An aspect built on a tense

The past continuous is usually taught as the second past tense a learner meets, and in a classroom that is a sensible fiction. Strictly, it is not a tense at all.

The Cambridge English TKT Glossary, the reference list used across the Teaching Knowledge Test, defines aspect as a way of looking at verb forms without looking specifically at the time of the action or event, and adds that the continuous/progressive aspect may describe an action that is in progress at a particular time. English marks tense in two places, present and past, and the past continuous is the past tense of be with continuous aspect stacked on top. The time comes from was and were. The sense of being in progress comes from -ing.

That matters in practice for one reason. Everything a class already knows about was and were, including the negative, the question and the fact that did never appears, transfers directly to the new form. A teacher who presents it as a fresh tense with fresh rules is making it harder than it is.

How it is formed

The British Council states the rule in one line: the past continuous is made from the past tense of the verb be and the -ing form of a verb. Because the auxiliary is be, the negative and the question are simpler than in the past simple. There is no did to introduce and no base form to return to.

The spelling of the -ing form follows the same three rules as the present continuous: a final silent e is dropped, as in making; a single final consonant after a single stressed vowel is doubled, as in sitting and running; and ie becomes y, as in lying. A class that has done the present continuous has already done this.

The five uses, in the British Council wording

The British Council LearnEnglish grammar reference lists five uses. The first is the one every coursebook teaches and the one most worth the lesson time. The other four are extensions of the same idea, that the action was spread out over a period rather than done at a point.

Use categories and examples quoted from the British Council LearnEnglish page Past continuous. The fourth use, with always, usually carries a note of irritation, and that is worth teaching because learners who use it neutrally will sound more annoyed than they mean to.

The interrupted action pattern

This is the pattern the form is taught for and the pattern most of its real use falls into. Two past actions are set against each other. The longer one, already in progress, takes the past continuous. The shorter one, which happens in the middle of it, takes the past simple.

The two sentences describe the same event. What changes is which clause carries when or while, and the choice is not free.

The clauses can be swapped round in every row with a comma, so When the phone rang, I was cooking is equally correct. What does not work is while with the short event. While the phone rang makes the ring last as long as the cooking, which is rarely what the speaker means.

Two further points belong in the same lesson. First, two past continuous forms together mean two long actions running in parallel: I was cooking while she was reading, with no interruption at all. Second, two past simple forms together mean one event followed by another: When the phone rang, I answered it. Only the mixed pattern gives the interruption, and that is why the form is taught in contrast with the past simple rather than on its own.

How it is used in practice

1. Draw the timeline before you say the rule. A long wavy line for the continuous action and a short vertical stroke cutting across it for the past simple event. The picture does more than the explanation, and learners can point at it when they are not sure which form a clause needs.
2. Teach it against the past simple, not after it. The form has no meaning on its own in the interrupted action pattern. Every presentation sentence should contain both forms, and every controlled practice item should make the learner choose between them.
3. Ask what the context trains. A lesson built on what were you doing at nine o’clock last night trains the continuous for every verb last night, which is the failure case below. A context built on interruptions trains the contrast.
4. Use a concept checking question on duration. Did the walking take a long time? Did the rain start suddenly? Which started first? Three questions settle most cases faster than a rule does.
5. Keep stative verbs out of the practice stage. A gap fill that asks learners to put know or want into the past continuous teaches an error. Choose activity verbs for the practice and deal with the stative limit as a separate, short stage.

A worked classroom example

An A2 group of ten adults in a morning class, mostly Spanish and Brazilian Portuguese speakers with one Polish and one Vietnamese learner. The target is the past continuous in the interrupted action pattern, and the teacher has sixty minutes.

She opens with a short story about her own weekend. She was cycling to the shops when her chain came off. She was fixing it when a neighbour stopped to help. The class listens twice and on the second listening writes every verb they hear, which gives a board list of was cycling, came off, was fixing, stopped. She asks the class to sort the four into two columns and to say what the difference is, which is guided discovery and takes a few minutes.

She draws the timeline, labels the two columns with it, and the class produces the pattern correctly in the controlled stage. Then the freer practice, in which learners tell a partner about something that happened to them last week, produces this from one of the Spanish speakers: I was watching a film when my brother was arriving.

The teacher does exactly that, on the board, with the class watching. She draws the long line for watching a film, asks where the arriving goes, and the learner draws a short stroke across it without being told. The next three sentences from the group all carry the contrast. The repair cost two minutes and it was cheaper than a second lesson.

Common learner errors

The form is easy. Almost every error is in the choice between the two past forms, and the pattern of errors is predictable from the learner’s first language, which makes this one of the clearer cases of L1 interference in the tense system.

What the research says about how it is learned

The best developed account of how second language learners pick up English tense and aspect is the Aspect Hypothesis, set out at book length by Bardovi-Harlig (2000). Its claim about the progressive is specific: learners first attach -ing to activity verbs, the ones that describe something going on with no built in endpoint, such as walk, play and talk, and only later extend it to verbs with an endpoint and, in error, to states.

Muñoz and Gilabert (2011) tested this with instructed Catalan and Spanish bilingual learners of English and found the association between -ing and durative verbs held across proficiency levels, though not as tightly to activity verbs as the strongest version of the hypothesis predicts. Qian (2015) found the same prototype pattern in Chinese and Mongolian learners and, alongside it, the overextension of -ing to stative verbs noted in the error table above.

Two limits are worth stating. Most of this research describes what learners produce, not what instruction should do about it, and Thane (2018) reviews a body of later work showing that first language, task type and the teaching materials all bend the sequence. For a classroom the practical reading is modest: start the form on activity verbs, because that is where learners will place it anyway, and treat the stative limit as a separate teaching point rather than expecting it to emerge.

Frequently asked questions

What is the past continuous tense?

It is the English verb form made with was or were plus the -ing form of a verb, as in I was working and they were waiting. It describes an action that was in progress at a particular time in the past, and it most often sets the scene for a shorter event told in the past simple.

Is the past continuous the same as the past progressive?

Yes. The two names describe one form. British coursebooks and the Cambridge teaching awards tend to say continuous, while North American materials and much of the research literature say progressive. Learners will meet both labels and should be told they mean the same thing.

How do you form the past continuous?

Use was with I, he, she and it, and were with you, we and they, followed by the verb plus -ing. The negative puts not after was or were, and the question moves was or were in front of the subject. No did is involved at any point, which is the main formal difference from the past simple.

What is the difference between the past continuous and the past simple?

The past simple reports a completed event and moves a story forward. The past continuous describes an action that was already in progress and gives the background. In I was cooking when the phone rang, the cooking was under way, the ring interrupted it, and the two forms together tell the listener which was the longer action.

Which verbs are not used in the past continuous?

Stative verbs, which describe states rather than actions, are not normally used in any continuous form. These include know, believe, want, need, own and belong. The British Council gives the example that on getting home a speaker needed a shower rather than was needing one. A few verbs, such as think and have, are stative in one meaning and dynamic in another.

When is the past continuous taught?

Most coursebooks introduce it at A2, usually a few units after the past simple and almost always in the interrupted action pattern with when and while. It is then recycled at B1 for narrative writing. The practical trigger is that learners can already form the past simple and know was and were, because the new form depends on both.

Where the term comes from

The word entered language teaching through second language acquisition research rather than through teacher training. Michael Long’s work on the linguistic environment in the 1990s treated the recast as a form of negative evidence delivered inside meaningful talk, borrowing the idea from studies of how adults respond to small children, who are rarely told they are wrong and are frequently echoed back in corrected form.

The term became standard in classrooms through Roy Lyster and Leila Ranta’s 1997 study Corrective Feedback and Learner Uptake: Negotiation of Form in Communicative Classrooms, published in Studies in Second Language Acquisition 19(1), pages 37 to 66. They recorded 18.3 hours of interaction across 27 lessons in four primary French immersion classrooms in Montreal, and sorted every correction a teacher made into six categories. Those six categories are still the standard vocabulary for talking about correction, and the recast is the first of them.

Their headline finding was not that recasts are common. It was the combination: teachers showed an overwhelming tendency to use recasts in spite of the latter’s ineffectiveness at eliciting student-generated repair.

The numbers that made the term famous

All figures below are from Lyster and Ranta (1997) and describe their four immersion classrooms. They are the most quoted numbers in the correction literature and they are not a universal constant.

Uptake, meaning any learner response at all following the feedback, ran at 31% after a recast, 50% after explicit correction and 100% after elicitation. More than half of all correction in those classrooms was delivered by the move that drew the least response.

How it is used in practice

A recast takes one turn and costs nothing in lesson time, which is a large part of why it dominates. It has three common shapes.

1. The full recast. The teacher repeats the whole utterance with the error fixed. Natural, invisible, and the easiest to miss.
2. The partial recast. The teacher repeats only the corrected fragment, which isolates the error and makes it far more noticeable. This is the version worth practising.
3. The stressed recast. The corrected element carries extra stress or a rising tone, which pushes an implicit move towards the explicit end without ever naming the mistake.

Translation counts as a recast too. When a learner reaches for their first language and the teacher supplies the English, the move is doing the same job: the meaning is accepted and the form is supplied.

Recasts are the default during fluency work, where stopping a speaker to analyse a verb ending costs more than the error does. They are a weaker choice during accuracy work, where the whole point of the stage is that the learner produces the form.

A worked classroom example

A B1 evening class of nine adults in Cork, thirty minutes into a speaking lesson about holidays. The teacher is not correcting much, deliberately, because the aim of the stage is fluency.

A learner says: I go to Spain last summer with my brother.

The teacher says: Ah, you went to Spain last summer.

The learner says: Yes, very hot. The conversation continues.

This is the characteristic failure of the technique, and it is not a failure of attention on the learner’s part. It is a design problem. Lyster’s 1998 follow-up study classified 377 recasts from the same corpus and compared them with the teachers’ non-corrective repetitions, where nothing was wrong and the teacher simply echoed a learner. The two moves turned out to serve identical functions in roughly equal proportions, and teachers delivered positive feedback such as good and yes alongside both of them at similar rates. From where the learner is sitting, a correction and an agreement can be acoustically and pragmatically the same event.

Two cheap repairs are available, and neither requires abandoning the technique.

Make the recast partial. Instead of returning the whole sentence, return the fragment: You went. Three syllables, the error isolated, and the flow of the conversation barely disturbed. The learner has something to compare against because only one thing came back.

Or switch to a prompt. You go, or you went. That is elicitation, it costs one extra turn, and it is the move the research says is most likely to get the learner to say the right form themselves.

Commonly confused with

What the evidence actually supports

The recast is the one correction technique that is routinely described as both the most common and the least effective, and that summary is too simple in a way worth understanding.

Lyster and Ranta measured uptake and repair: what the learner did in the turn immediately after the feedback. On that measure the recast performs badly, and necessarily so, because a move that supplies the answer cannot also produce an answer. What it does not measure is acquisition. A learner who says nothing in the next turn may still have registered the difference.

Later meta-analytic work, including Lyster and Saito’s synthesis of oral feedback in classroom settings, found that corrective feedback as a whole does help, and that prompts tended to outproduce recasts in classroom studies while recasts held up better in laboratory conditions. Dan Brown’s meta-analysis of observational studies confirmed the frequency pattern across many more classrooms than the original four: reformulating moves, recasts chief among them, still account for roughly two thirds of what teachers do.

Three honest limits follow, and they are usually left off pages about this term.

• The famous numbers come from four classrooms of children in French immersion. Not adults, not English, not a language school. The six categories travel well. The percentages should be treated as a finding about those rooms rather than a law.
• Low uptake is not proof of low learning. It is proof of low visible response, which is what was counted. This page does not claim recasts fail to teach anything, because the study design cannot show that.
• Noticing is the live question. The evidence that recasts work is strongest where learners could tell a correction was happening. That is an argument for making recasts more salient, not for abandoning them.

The defensible claim is a narrow one. A recast is the right move when the priority is keeping a learner talking, and it becomes a wasted move when it is used so often, and so gently, that nobody in the room can tell it apart from agreement.

Frequently asked questions

Is a recast the same as correcting a student?

It is one way of correcting, and the quietest one. A recast supplies the right form inside an ordinary-sounding reply and never says that anything was wrong. That is what separates it from explicit correction, which names the error first, and from prompts, which point at the error and leave the learner to fix it.

Do recasts actually work?

They work less visibly than the alternatives rather than not at all. The classic study measured what learners did in the very next turn, and on that measure recasts came last, because a move that hands over the answer cannot also produce one. Later meta-analyses found that corrective feedback does aid acquisition and that recasts perform better when learners can tell a correction is taking place.

When should I use a recast rather than a prompt?

Use a recast when the stage is about fluency and stopping the speaker would cost more than the error does, when the learner is fragile or new to the group, or when the item is beyond their current level and they could not produce it if asked. Use a prompt when the form is one the learner already knows and has simply slipped on, which is most of the time during accuracy work.

What is the difference between an implicit and an explicit recast?

It is a matter of degree rather than a hard line. A full recast delivered in a normal tone is at the implicit end and is easy to miss. Shortening it to the corrected fragment, adding stress to the changed element, or using a questioning tone pushes it towards the explicit end while still never stating that an error occurred.

Can recasts be used in written work?

The written equivalent is usually called reformulation: the learner’s text rewritten in correct English so the two can be compared side by side. It is more effective than a spoken recast for the simple reason that a written version sits still, and the learner can look from one to the other for as long as they need.

Why do teachers use recasts so much if they produce less repair?

Because they cost nothing. A recast takes one turn, breaks no one’s concentration, embarrasses nobody and lets the conversation carry on. Every other correction move costs time or face or both. The honest answer is that the recast is popular for the teacher’s reasons as much as the learner’s, which is why counting your own is a useful exercise.

Tense, or aspect

Almost every coursebook, syllabus and job advertisement calls it the present perfect tense, and almost every grammar reference says that is not quite what it is.

The Cambridge English TKT Glossary, the reference list used across the Teaching Knowledge Test, draws the line clearly. Aspect is a way of looking at verb forms without looking specifically at the time of the action or event, it says, and there are two aspects in English, the continuous/progressive aspect and the perfect aspect. English has two tenses, present and past. Perfect is something layered on top of one of them.

So the present perfect is the present tense carrying perfect aspect. The verb that is actually marked for tense is have, and it is marked present: I have, she has. The past participle is not a tense at all.

This matters in a classroom for one practical reason. A learner who has been told the form is a past tense will reach for it whenever they talk about the past, which is the single most common source of error with it. A learner who has grasped that it is a present form, built out of something earlier, has the rule.

How it is formed

The British Council states the formation in one sentence: The present perfect is formed from the present tense of the verb have and the past participle of a verb.

The contracted forms are what learners will actually hear. I’ve, you’ve, he’s, we’ve, they’ve, and in negatives haven’t and hasn’t. In connected speech the contraction is often barely audible, which is a listening problem before it is a grammar problem.

The three uses, in the British Council wording

The British Council LearnEnglish grammar reference groups the uses into three, and the grouping is a sound basis for a lesson because each one maps onto a different set of time expressions.

Use categories quoted from the British Council LearnEnglish page Present perfect. The same page also covers have been against have gone, and the present perfect continuous.

How it is used in practice

A present perfect lesson differs from most grammar lessons in one respect. The form is easy and the meaning is not, so the time spent on each should be the reverse of what most lesson plans allow.

1. Teach one use at a time. The three uses above look related to a teacher and unrelated to a learner. A lesson that presents all three at once produces a class that can conjugate the form and cannot choose it.
2. Put the time expression at the centre. Since, for, ever, just and yet do more work in deciding the form than any abstract rule does. Learners can be taught to spot them long before they can explain them.
3. Drill the contraction, not the full form. Learners who only ever practise I have seen will not hear I’ve seen in the wild. A short drilling stage on the contracted forms pays for itself in the listening lesson three weeks later.
4. Check meaning before you check form. A class can produce a flawless present perfect sentence while believing it means a distant past, so a round of concept checking questions belongs before the controlled practice, not after it.

A worked classroom example

A B1 group of nine adults in a morning class, most of them Spanish and Portuguese speakers, one Polish. The target is the third use, a past event with a present result, and the teacher has an hour.

She starts with a picture of a kitchen with a broken window and asks what happened. The class answers in the past simple, correctly and fluently: someone broke the window. She then asks a second question, which is what the room looks like now, and writes the class answer on the board next to the first one.

The pair is the whole lesson. Both sentences are true, both describe the same event, and the difference between them is not in the event at all. It is in which question the speaker is answering.

The class takes it quickly, and then the controlled practice produces a sentence she was not expecting: I have broken my arm when I was fifteen.

She does not explain this. She writes three time phrases on the board, this week, last week and when I was fifteen, and asks which of them is over. The class sorts them in seconds, and the rule follows from the sort rather than from her.

The lesson that ought to follow is not more present perfect. It is the comparison below, because a learner who can only produce the present perfect in isolation has learned a form rather than a choice.

Present perfect and past simple

This is the distinction learners ask about, the one examiners test, and the one that takes the longest to settle. The British Council lists four uses of the past simple, including something that happened once in the past, something that happened several times in the past and something that was true for some time in the past, with expressions with ago as the characteristic marker.

The fourth row is worth teaching explicitly because it is the pattern of ordinary conversation. The present perfect announces, the past simple narrates. Once a speaker has said I have been to Lisbon and the listener has asked when, everything after that is past simple.

Commonly confused with

Why it is hard, and for whom

The difficulty is unevenly distributed, and it is largely predictable from the learner’s first language. This is L1 interference in its most visible form.

Speakers of Spanish, Portuguese, Italian and French all have a compound past built the same way, with an auxiliary plus a participle, and in several of those languages it has drifted into general past narration. The form transfers across intact and the meaning does not, which is why a Spanish speaker will produce I have seen him yesterday with complete confidence. The sentence is not a guess. It is a correct sentence in another language.

Speakers of Slavic languages, Chinese, Japanese, Korean, Arabic and Turkish face the opposite problem. There is no compound past to transfer, so there is nothing to interfere, but also nothing to build on. Those learners tend to underuse the present perfect rather than misuse it, defaulting to the past simple everywhere. This is harder to notice in a classroom, because underuse produces sentences that are grammatical.

The practical consequence for a mixed class is that the same lesson is doing two different jobs in the same room, and the error correction that follows it should not be uniform.

A note on levels

Coursebook syllabuses usually introduce the present perfect late at A2 and work on it through B1 and B2, and teachers often report that placement as though the Common European Framework prescribed it. It does not.

The Council of Europe describes the framework’s six levels, A1 to C2, grouped as Basic User, Independent User and Proficient User, and says the levels are defined through ‘can-do’ descriptors that were created without reference to any specific language. There is no CEFR grammar syllabus, and no level at which the present perfect is officially due. The sequencing is publishing convention and classroom experience, which are reasonable grounds, and they are not the same as a standard.

Frequently asked questions

Is the present perfect a tense or an aspect?

Strictly it is an aspect carried on the present tense. English has two tenses, present and past, and two aspects, continuous and perfect, and the Cambridge English TKT Glossary defines aspect as a way of looking at verb forms without looking specifically at the time of the event. Almost everyone calls it a tense anyway, including coursebooks and exam syllabuses, and that is fine as a label. It stops being fine when a learner concludes from the word tense that the form belongs to the past.

What is the difference between the present perfect and the past simple?

The reliable test is the time reference rather than how long ago the event happened. If the time period is finished, or a specific past time is stated, the past simple is required. If the period still includes now, or no time is stated and the point is the present result, the present perfect is available. I saw him yesterday and I have seen him today can describe events a day apart.

Why do Spanish and Portuguese speakers overuse the present perfect in English?

Because their languages have a compound past built the same way, from an auxiliary plus a participle, which in ordinary use covers ground that English gives to the past simple. The form transfers across and the restriction on finished time references does not. The resulting sentence, such as I have seen him yesterday, is a confident translation rather than a careless mistake, which is why it survives correction so well.

Can you use the present perfect with a specific time?

No. A stated finished time such as yesterday, last week, in 2019 or when I was fifteen blocks the form, however relevant the event still is. Time expressions that include the present, such as today, this week or since Monday, are compatible with it. This is the one part of the grammar that is mechanical, and it is worth teaching as a constraint rather than as a preference.

When should the present perfect be introduced?

Coursebooks usually bring it in late at A2 and develop it through B1 and B2. That sequencing is a publishing convention rather than a requirement, because the Common European Framework defines its levels through can-do descriptors created without reference to any specific language and sets no grammar syllabus. In practice the useful trigger is whether learners can already handle the past simple comfortably, since the present perfect is taught against it.

Is did you eat yet wrong?

It is standard in American English and non standard in British English, where the present perfect is expected with yet, just and already. A learner preparing for a Cambridge or IELTS exam should use the present perfect. A learner working in the United States will hear the past simple constantly and should know it is correct there. Saying only that it is wrong leaves the learner unable to explain what they have heard.

Where the term comes from

The Cambridge English TKT Glossary, the reference list used across the Teaching Knowledge Test, defines guided discovery as an approach to teaching in which a teacher provides examples of the target language and then guides the learners to work out the language rules for themselves. Its worked case is a reading article containing examples of reported speech: learners find the examples, then answer questions about the grammar rules and the meaning of those examples.

The British Council Teaching Knowledge Database makes the contrast explicit. Guided discovery, it says, can be compared to didactic instruction, where the teacher sets out rules for students and then asks them to practice. Its example is a problem page carrying several instances of the second conditional, from which learners identify the structure and then the rules for forming it.

The wider idea is older than English language teaching and belongs to Jerome Bruner, whose 1961 paper The act of discovery argued that a rule arrived at by the learner is better retained than a rule received. English language teaching took the principle and added the word that does the work in it, which is guided. The route is set in advance by somebody who already knows where it ends.

Inductive and deductive, in the British Council wording

Guided discovery is the classroom form of an inductive approach, and the cleanest statement of that pair is the British Council one.

Wordings quoted from the British Council TeachingEnglish page Presenting new language. Inductive is the orientation; guided discovery is one way of running it in a room.

How it is used in practice

A guided discovery stage usually sits where a presentation stage would sit, at the front of a lesson, and it runs in four moves.

1. Choose the examples before anything else. Six to ten short sentences, all carrying the target item, written or chosen so that the only thing that varies between them is the thing you want noticed. This is the part that decides whether the stage works.
2. Give a sorting task, not a question. Learners match the examples to two timelines, two pictures, two situations or two headings. Sorting forces attention onto the distinction without asking anyone to name it.
3. Ask two or three questions that point at the difference. Short, answerable from the examples on the page, and in language simpler than the rule itself.
4. Let the class state the rule, then tidy the wording. The learners supply the content. The teacher supplies the terminology and the correction, and only at this point.

Pair or small group work is the norm at steps two and three, which is the point the British Council makes when it notes that guided discovery encourages independence, makes learning more memorable, and if analysis is done in groups is a meaningful communicative task.

A worked classroom example

A B1 group of eleven adults in an evening class in Galway. The target is the difference between the present perfect and the past simple with a stated length of time. The teacher wants the class to arrive at the idea that one of them describes a situation that is still true and the other one does not.

She puts six sentences about the same invented person on a handout:

The sorting task is two headings on the board, still true today and finished, and three minutes in pairs. Every pair sorts all six correctly. Then three questions: which column has has in it, which column tells you the person is still there, and does the sentence tell you when it started or when it stopped.

A learner states the rule and she states it clearly: the present perfect is for long things, the past simple is for short things.

Every learner in the room agrees, and the rule is wrong. It is also the only rule the handout supports. Ten years, 2019 and six years are all long. Three years, eight months and two seasons are all shorter. The sorting worked, the questions worked, and the class extracted a pattern that was genuinely there in the data they were given, because the teacher had chosen her examples for realism rather than for contrast.

Two minutes of concept checking follow, because a rule a class has stated is not yet a rule the class can use. That is the division of labour between the two techniques: guided discovery gets the rule out, concept checking questions confirm the meaning has landed.

The examples are the lesson

The usual advice about guided discovery is about questioning technique, and questioning technique is the easy part. The part that decides the outcome happens before the class walks in, when the teacher chooses which six sentences go on the page.

A set of examples is a small body of evidence, and learners do with it exactly what anyone does with evidence: they find the strongest pattern in it. If an irrelevant feature is present in every example, that feature becomes the rule. The Galway class did nothing wrong. They read the data correctly.

This produces the characteristic failure of the technique, and it is worse than the failure of a plain explanation. A learner who misunderstands an explanation holds the mistaken rule loosely and will drop it when corrected. A learner who derived a wrong rule from evidence holds it with the confidence of someone who worked it out, and will defend it. The discovery that makes the right rule stick makes the wrong one stick too.

The practical consequence is a design rule rather than a teaching tip. Build the example set so that the target feature is the only thing that varies, then look over the finished set and ask what other pattern a clever learner could extract from it. If one is there, break it with an extra example before the lesson rather than after it.

Commonly confused with

What the evidence actually supports

Guided discovery is often defended, and attacked, with research that is not about it.

Richard Mayer’s 2004 paper in American Psychologist, Should there be a three-strikes rule against pure discovery learning?, reviews three decades of studies on problem solving rules, conservation strategies and programming. Its conclusion is specific: in each case guided discovery was more effective than pure discovery in helping students learn and transfer. The paper is a case against unguided exploration and, in passing, a point in favour of the guided version.

Kirschner, Sweller and Clark’s 2006 paper in Educational Psychologist goes further against minimal guidance, and adds the qualification that matters most in a language classroom: the advantage of guidance begins to recede only when learners have sufficiently high prior knowledge to provide internal guidance. Read plainly, that is an argument for heavier guidance with beginners and lighter guidance with learners who already have something to work from.

Two honest limits follow from this, and neither is usually stated on pages about the technique.

• None of that research is about English language teaching. It is educational psychology on school and university learners in other subjects. There is no body of controlled trials showing that a guided discovery stage beats a clear explanation for teaching a grammar point to an adult language class, and this page does not claim one.
• Some learners do not want it. The British Council records this directly, noting that it is important, however, to understand that some learners are resistant to this approach. Learners who have been taught deductively for years can read a discovery stage as the teacher withholding an answer they are paid to give.

The defensible claim is the narrow one. Guided discovery is a reasonable use of class time when the rule is worth the minutes, when the class has enough language to read the examples, and when the teacher has built an example set that cannot support a second interpretation.

Frequently asked questions

Is guided discovery the same as inductive teaching?

Not quite. Inductive describes the direction, from examples towards a rule. Guided discovery is one procedure for running that direction in a classroom, with chosen examples, a sorting or matching task and directed questions. Every guided discovery stage is inductive, but a teacher can work inductively in looser ways that would not be called guided discovery.

Does guided discovery work with beginners?

It works less well, and the research explains why. Kirschner, Sweller and Clark found that the advantage of guidance recedes only once learners have enough prior knowledge to guide themselves, which means the lower the level, the heavier the guidance needs to be. With genuine beginners the examples often cannot be read at all, and a short clear presentation is usually the better use of the time.

How long should a guided discovery stage take?

Between ten and twenty minutes for a single grammar point in a sixty minute class is typical, including the pair work and the restatement. Set the limit in advance. If the rule has not surfaced within it, state the rule and move to practice rather than extending the stage, because the time saved by an explanation is the whole argument against discovery in the first place.

What happens if the class works out the wrong rule?

Add an example that the wrong rule cannot account for, and let the class see it fail. Correcting the rule directly wastes the stage and teaches the class that the discovery was decorative. A wrong rule reached from evidence is also held more firmly than one misheard from a teacher, so it needs disconfirming evidence rather than contradiction.

Is guided discovery better than simply explaining the rule?

There is no reliable evidence either way for language classrooms specifically. The research that is usually cited compares guided discovery with unguided discovery, not with clear explanation, and it favours guidance in both comparisons. What can be said is that discovery costs more class time, so it is worth spending on rules that reward attention and not on items a single sentence would settle.

Can guided discovery be used for vocabulary and pronunciation, or only grammar?

It is used for all three. Vocabulary works well when the target is a pattern rather than an item, such as how a set of phrasal verbs behaves with objects, or the shades of meaning across a group of near synonyms. Pronunciation works when learners sort recorded or written examples by a feature such as stress placement or a voiced and unvoiced contrast, then state what governs it.

How concept checking questions are used in practice

The problem a CCQ solves is narrow and very common. A teacher presents a structure, explains it, and then asks the class whether that is clear. Almost everyone says yes. Some say yes because they do understand, some because they do not want to hold the lesson up, some because they believe they understand and do not, and some because saying no in front of a class of peers costs more than staying quiet. The answer carries no information, so the teacher moves on to practice on top of a misunderstanding that surfaces twenty minutes later as a pattern of identical errors.

A CCQ removes the social pressure by not asking about understanding at all. It asks about the situation. If the target sentence is She must be stuck in traffic, the class is not asked what must means; they are asked whether the speaker knows for certain, and whether the speaker has a reason for thinking it. Those are questions a learner who has grasped deduction can answer and a learner who has read must as obligation cannot.

The Cambridge English TKT glossary makes the distinction between the question and the wider habit. A concept question is the individual question. Concept checking is the technique, and it includes concept questions alongside realia, timelines, asking learners to explain the meaning in their own words, and asking learners to repeat instructions back. The British Council’s Teaching Knowledge Database describes concept checking as especially important in inductive teaching, where learners work a rule out from examples rather than being given it, because in that case nobody has yet said out loud what the rule is.

Building a CCQ in four steps

The British Council’s guidance on checking understanding adds the constraints that make these questions work: keep the language simple enough that no difficult English is needed to answer, keep the new grammar out of the question, avoid unfamiliar vocabulary, bring out basic concepts such as time, and ask enough questions to cover several aspects of the item and several learners.

A worked classroom example

An intermediate evening class of fourteen adults in Galway, ninety minutes, the target language a set of deduction modals. The teacher has put She must be stuck in traffic on the board inside a short context: two colleagues waiting in a meeting room, the third one late, her car normally parked outside and not there. The teacher then runs three concept checking questions.

The first two questions came back clean. The third split the room. Roughly half the class answered yes, and two learners produced She must go to work as an example a minute later. That is the useful part of the lesson, and it is the part that would have been invisible behind a nod.

What the teacher did next is the load bearing move. She did not explain the grammar again, and she did not reach for the term modal of deduction. She went back to the context and added one line to it: the colleague phones and says she is on the motorway. Then she asked a fourth question, whether the speaker had been right, and a fifth, whether the speaker had known. Both answers landed. The class had not misunderstood an explanation; they had never been given a situation in which a guess and an instruction look different, and the fix was a situation rather than a rule.

Commonly confused with

Where the technique comes from, and what it does not do

Concept checking has no single author. It grew inside British initial teacher training in the 1980s and 1990s, where trainees were being asked to clarify meaning before practice and needed something better than an explanation followed by a hopeful question. It reached print through the standard training handbooks of that tradition, and it is now embedded in the Cambridge assessment vocabulary: the TKT glossary lists both concept question and concept checking as terms candidates are expected to know.

Two honest limits are worth stating on a page that recommends the technique. The first is that concept checking has a long practitioner literature and no body of controlled trials showing that classes whose teachers use CCQs learn more than classes whose teachers clarify meaning some other way. It is a discipline that makes understanding visible at the moment it is cheapest to repair, not a measured intervention, and no effect size is claimed for it anywhere on this page.

The second limit is that a CCQ can only check a concept the teacher has already analysed correctly. Writing the questions is the hard part, and it happens at the planning desk rather than in the room. A teacher who has not worked out that must in this sentence is a deduction will write three fluent questions about obligation, the class will answer all three correctly, and the check will confirm a misunderstanding rather than catch it.

Frequently asked questions

What is a concept checking question?

A concept checking question is a short question a teacher asks to confirm that learners have understood the meaning of a new word, phrase or structure, rather than asking them directly whether they understand. It uses simpler language than the target item, does not contain the target item, and expects a brief answer such as yes, no, or a single word.

How many concept checking questions should a teacher ask?

Two or three for each item is the working rule. A single yes or no question can be answered correctly by guessing, so it is weak evidence on its own, while a long run of questions turns clarification into interrogation and eats the practice time the check was meant to protect.

What makes a bad concept checking question?

Four faults account for most of them: the question contains the target language, so a learner can answer by recognition; the question uses harder words than the item being checked; the question carries two ideas at once, so a wrong answer does not say which idea failed; or the question supplies its own answer through a tag or an intonation pattern.

What is the difference between a CCQ and an ICQ?

A concept checking question checks that learners understand what a piece of language means. An instruction checking question checks that they understand what they have been asked to do in an activity, such as who they are working with or how long they have. CCQs come before practice; ICQs come before a task.

When in a lesson should concept checking questions be asked?

Directly after the meaning of the new language has been presented in a context and before learners move into controlled practice. That is the window in which a misunderstanding is cheap to repair. Once a class has drilled or produced a form it has misread, the teacher is no longer correcting a concept but unpicking a habit.

Can concept checking questions be used with beginners?

Yes, and they matter more at low levels, because a beginner has fewer ways to signal confusion. The constraint is that the question must be answerable with the English the class already has, so at beginner level checks lean on yes or no answers, either or choices, pictures, real objects and gesture rather than on wording alone.

Related terms

Concept checking sits between two techniques in the same stage of a lesson. Eliciting draws language out of learners before the teacher supplies it, and a concept check confirms that what was supplied has landed. Drilling comes next, and the order matters: a class that drills a form it has misunderstood is rehearsing the misunderstanding. In the presentation, practice, production framework the check belongs at the end of the presentation stage, and every entry in this set is listed in the tefl.ai glossary of teaching methods and classroom techniques.

How drilling is used in practice

A drill has three moving parts: a model, a prompt and a response. The teacher supplies the model, gives a signal or a cue, and the learners produce the response. Because the response is fixed, or nearly fixed, the learner has almost no choice about what to say. That is the defining feature. The British Council puts it plainly in its guidance on the technique: in all drills learners have no or very little choice over what is said, so drills are a form of very controlled practice, there is one correct answer, and the focus is on getting it right.

That constraint is the point. It frees attention. A learner who is not deciding what to say can spend the whole of their attention on how to say it, which is exactly what a difficult consonant cluster or an unfamiliar stress pattern demands. It is also the technique’s limit, and the reason a lesson made only of drills produces learners who can perform sentences and not hold conversations.

The main types of drill

The substitution and question and answer examples above are the British Council’s own, taken from its Drilling 1 article and its teaching knowledge database entry for drill.

What is worth drilling, and what is not

The other half of that list matters as much. The British Council’s guidance is explicit that drilling structures for their own sake is much less likely to be useful, because applying a grammar rule accurately takes mental processing that repetition does not supply, particularly when the language is new. A class can chant the third conditional faultlessly and still fail to produce it when they need it, and every experienced teacher has watched exactly that happen.

A worked classroom example

An A2 class of eighteen adults in a general English course. The target is a single functional phrase they will need from their first week in an English speaking workplace: Could you say that again, please? The difficulty is not the words. It is that could you runs together into something closer to one syllable, and that the phrase needs a polite rising contour rather than the flat delivery learners default to when reading.

Two things carry the example. The first is that the drill lasted under two minutes. The British Council’s advice is to keep drilling snappy and to stop before boredom sets in, on the grounds that a bored drill is unlikely to be useful at all. The second is move five. A drill with no transfer stage is the version of the technique that gave drilling its poor reputation, and the fix costs one activity.

Commonly confused

Where drilling came from, and why it fell out of favour

Drilling as a systematic classroom procedure belongs to the audiolingual method, which grew out of intensive wartime language programmes in the United States and was codified at the University of Michigan by Charles Fries and his colleagues in the years after 1945. Its two supports were structural linguistics, which treated a language as an inventory of patterns, and behaviourist psychology, which treated language learning as habit formation through stimulus, response and reinforcement. If a language was a set of habits, then drilling those habits to the point of automatic production was not one technique among many. It was the whole curriculum.

The theoretical support gave way first. Noam Chomsky’s 1959 review of B. F. Skinner’s Verbal Behavior argued that habit formation could not account for the fact that speakers routinely produce and understand sentences they have never heard, and the field moved on. The British Council’s own summary of the position is blunt: the behaviourist view held that repeating phrases correctly enough times would lead to mastery, we now know language learning is not like this, and an approach based mainly or only on language drills is unlikely to find many adherents today.

What did not follow, and what the more careless version of this history gets wrong, is that drilling itself was disproved. The method was abandoned. The technique was demoted. The British Council’s same guidance goes on to say that drilling remains a useful technique in the classroom if it is used appropriately, and in practice it never left: teachers who would describe their approach as communicative still drill a difficult phrase before a role play, because it works for that job.

What the research actually supports

The honest position is that the evidence for repetition is strongest where drilling’s defenders now place it, on pronunciation and on the automaticity of fixed forms, and weakest where audiolingualism placed it, on grammatical competence. A study by Jung, Kim and Murphy in Studies in Second Language Acquisition in 2017 tested this with fifty seven Korean high school learners across three groups over four weeks, measuring the production of English word stress patterns. Both repetition conditions improved accuracy, and for longer term retention repeating the same task with the same content twice beat repeating the procedure with different content. That is a narrow finding about lexical stress and priming tasks rather than a general endorsement of drills, and it should be read as such, but it points the same way as classroom experience: repeated production of the same target does shape how learners say things.

The claim that drilling builds the ability to communicate has no comparable support, and the page makes no such claim. Pronunciation notation is a useful companion here, and the Group’s global reference on it sits on the International Phonetic Alphabet for English teachers. For activity level treatment of the same ground in a European classroom, see TEFL.ie’s pronunciation activities for European English teachers.

Frequently asked questions

What is drilling in teaching English?

Drilling is controlled repetition of a target word, phrase or structure, led by the teacher, to build accuracy and automaticity in production. The teacher gives a model, learners repeat it chorally and then individually, and variations substitute one element at a time. It is a classroom technique rather than a method, and it can be used within almost any approach to teaching.

What are the main types of drill?

The common types are repetition drills, in which learners say back an unchanged model; choral drills, in which the whole class responds together; individual drills, in which one nominated learner responds; substitution drills, in which the teacher changes one cue each time; and question and answer drills, which practise a short exchange rather than a single line. Back chaining, building a phrase from its final word backwards, is a way of running any of these rather than a separate type.

Is drilling still used in modern language teaching?

Yes, though in a much smaller role than it had under the audiolingual method. The British Council’s position is that an approach based mainly or only on drills is unlikely to find many adherents today, but that drilling remains a useful technique when used appropriately. In practice most communicative classrooms still drill, usually briefly and usually for pronunciation, before learners use the language in a freer task.

What should teachers drill, and what should they not drill?

Drill what causes trouble in the mouth: sounds absent from the learners’ first language, consonant clusters, weak forms and linking, word and sentence stress, meaningful intonation patterns, and high frequency fixed chunks. Drilling grammatical structures for their own sake is much less productive, because applying a rule accurately requires mental processing that repetition does not provide, particularly when the language is new to the class.

How long should a drilling stage last?

There is no established figure, and any source offering one is guessing. The usable guidance is qualitative: keep the pace snappy, vary who repeats, and stop before the class loses interest, because a drill that has become boring is unlikely to be doing any good. In most lessons this means a stage measured in a small number of minutes rather than a block of the lesson.

What is the difference between drilling and eliciting?

The two techniques move in opposite directions. In eliciting the teacher supplies a prompt and the learners supply the language, which reveals what the class already knows. In drilling the teacher supplies the language and the learners supply the repetition, which shapes how accurately they can produce it. They are complementary rather than alternative, and a well built presentation stage often elicits a phrase first and then drills it.

Related entries in this glossary

Drilling sits inside the practice stage of a lesson, so it is best read alongside presentation, practice, production, which is the framework that gives the drill its place in a lesson shape. It is also teacher fronted by design, which makes it a recurring item in any discussion of teacher talking time versus student talking time, where the useful question is not how much the teacher speaks but what the speaking is doing. The comfort of choral repetition, and why exposed individual repetition can backfire, is covered in the entry on the affective filter.

What L1 interference actually means

Every learner arrives with a complete language already installed. When they meet a new one, they do what any efficient mind does: they look for correspondences and apply what they already know. Most of the time this is invisible and helpful. A Portuguese speaker meeting the English word possible has very little work to do. A Japanese speaker meeting it has a great deal more.

L1 interference is what happens at the points where the correspondence fails. The learner applies a first language rule in a place English does not accept it, and an error appears. The British Council’s teaching knowledge database defines it as the case “where a speaker uses language forms and structures from their first language in language they are learning”, and notes that it is “an area many teachers are concerned with”.

Three features make it different from ordinary error. It is systematic, so the same learner makes it repeatedly rather than at random. It is predictable, because it follows from the structure of the language pair and can be anticipated before a single lesson is taught. And it is shared, so in a class where everyone has the same first language, everyone makes it at once.

Where it shows up

The last two rows are the ones trainee teachers miss. Interference is usually taught as a grammar problem, and the errors that damage communication most are often the pragmatic and discourse ones, because the learner sounds fluent and rude rather than obviously wrong.

A worked classroom example

A B1 class of eleven teenagers in a Greek frontistirio, all with Greek as their first language, preparing for a Cambridge exam. The teacher sets a short written task and collects it. Three patterns come back across almost every script.

The teaching move that matters is the third column, and it is a decision procedure rather than a correction. The teacher asks three questions of every interference pattern.

1. Does it stop the listener understanding? If it does, it is a priority whatever else is true of it. If it does not, it joins a queue.
2. Is it shared by the class or personal to one learner? A shared pattern is worth ten minutes of board time. A personal one belongs in that learner’s feedback and nowhere else.
3. Is it a system difference or a slip? A slip is corrected in passing. A system difference needs its own lesson, because the learner is not failing to apply an English rule, they are applying a different one correctly.

Applied to this class, the article and adverb pattern is taught on Tuesday with a contrastive board stage, the present perfect is booked for its own lesson in a fortnight, and the vowel pair gets two minutes of drilling at the start of each class for a week. Nothing else on the scripts is touched. That restraint is the point. A teacher who red-pens every interference error in a monolingual class produces demoralised learners and no measurable change, because the errors that remain are the ones that were never taught.

Commonly confused with L1 interference

Where the idea came from, and what has survived

The term belongs to a specific moment in applied linguistics, and the history matters because the strong version of the idea was tested and failed.

Robert Lado’s Linguistics Across Cultures in 1957 set out the contrastive analysis hypothesis: compare two languages systematically, and the points of difference will predict where learners struggle. For a decade this was the field’s main tool, and the promise was total. Difficulty would be predictable in advance, and the syllabus could be built around the differences.

It did not hold. Pit Corder’s 1967 paper The significance of learners’ errors reframed error as evidence of a developing system rather than as failure, and the research that followed found that contrastive analysis both over-predicted and under-predicted. Many differences between languages caused no difficulty at all. Many of the errors learners actually made were developmental, shared by learners of every background, and had nothing to do with the first language. Larry Selinker’s 1972 paper named the learner’s system interlanguage and listed language transfer as only one of five processes shaping it.

What survived is the weaker and more useful claim, set out most carefully in Terence Odlin’s Language Transfer in 1989: the first language is a real and substantial influence on second language learning, it is one influence among several, and it works in both directions. Comparing two languages is good at explaining errors after they appear and unreliable at predicting them before. That is precisely how the concept should be used in a classroom, and it is why the decision procedure in the worked example above starts with observation of what learners actually produced rather than with a list of differences drawn up in advance.

Two cautions worth carrying into the classroom

Interference is not a defect. An error that follows the first language is evidence of an intelligent learner applying a working system to new material. Framing it to a class as carelessness is both wrong and demotivating, and anxiety about error is one of the conditions that raises the affective filter.

Not every learner has one first language. The British Council’s guidance on multilingual practice deliberately uses “learners’ other languages” instead of L1 or mother tongue, because many learners have no single dominant language. Its example is a learner who uses Mandarin at school, Malay and English with friends and Hokkien at home. For learners like that, the question is not what their L1 does, but which of their languages is shaping a given error. The concept still applies. The label is what needs loosening.

How to find out what your learners’ first language does

This is a needs analysis question, and it is cheap to answer. Three routes, in order of effort.

• Ask the class. In a monolingual group, learners can usually tell you how their language handles articles or word order once the question is put concretely. This also positions them as the experts on their own language, which the British Council explicitly recommends.
• Read a language-specific reference. Swan and Smith’s Learner English is the standard one, with a chapter per language group setting out the predictable difficulties.
• Collect and sort a set of scripts. One written task from the whole class, sorted into shared patterns and personal ones, is the most reliable evidence available and takes about forty minutes.

Frequently asked questions

What is L1 interference in simple terms?

It is what happens when a learner applies a rule from their first language to English and the rule does not fit. The learner is not being careless. They are using a system that works, in a place where it does not apply. The result is an error that is systematic and repeated rather than random.

Is L1 interference the same as negative transfer?

In practice the two terms are used interchangeably, and both name the same thing: first language influence that produces error. Negative transfer is the more precise of the pair, because it makes clear that there is also positive transfer, where the first language helps. Interference is the older and more common classroom term.

What causes L1 interference?

A structural difference between the two languages, met by a learner who does not yet know the English rule. Where the languages agree, the first language speeds learning up. Where they differ, and particularly where English makes a distinction the first language does not make at all, the learner defaults to what they know. Sound systems, article systems and tense distributions are the most common sites.

Should teachers correct every L1 interference error?

No. Correcting everything produces demoralised learners and very little change. Triage by three questions: does it obstruct understanding, is it shared by the class or personal to one learner, and is it a slip or a system difference. Shared system differences that obstruct understanding earn a lesson. Everything else waits or goes into individual feedback.

Can L1 interference be positive?

Interference is by definition the negative case, but the wider phenomenon it belongs to is not. Positive transfer is doing quiet work in every lesson: shared vocabulary, shared word order, shared script. A learner whose first language is closely related to English starts several thousand words ahead. Teachers notice transfer only when it fails, which makes the first language look like a purely negative influence when most of its effect is helpful.

How can teachers reduce L1 interference in a monolingual class?

Use the shared language rather than banning it. Make the difference between the two languages explicit at the board, use translation tasks that force learners to notice structural differences, and build the predictable problem areas into the scheme of work rather than reacting to them. A monolingual class is the easiest setting in which to address interference, because every learner has the same problem at the same time.

The three stages

The framework is set out by its authors in three stages, and the order is the whole point. Each stage answers a different question, and each one has to align with the others: what you named in stage one is what you assess in stage two and what you teach in stage three.

The authors describe the framework as guarding against two specific failures. One is treating the coursebook as the curriculum rather than as a resource. The other is activity oriented teaching, in which lessons are engaging but carry no clear priority or purpose. Both are recognisable in language teaching, and the second is the more comfortable of the two, because a class that is enjoying itself rarely complains.

How it is used in practice

In English language teaching the first stage is less exotic than it sounds, because the profession already has a shared vocabulary for outcomes. The Council of Europe built the CEFR around can do descriptors precisely so that a level could be stated as performance rather than as a list of structures, and those descriptors make a serviceable stage one when a course has no other stated goal. A stage one written as learners can take and pass on a phone message containing a name, a date and a reason is usable. A stage one written as the present perfect is not, because it names content rather than a result.

Stage two is where the method earns its keep, and it is the stage that separates backward design from ordinary good intentions. The question is not what test exists but what evidence would satisfy you. If the outcome is a phone message, the evidence is a phone message taken under something like real conditions, not a gap fill on reported speech. The British Council’s guidance on planning lessons and courses makes the same alignment point in simpler terms: any activities you plan to do should directly link to that aim or learning outcome, and each stage builds on the stage before it until the learners eventually have all the skills and language they need to achieve the learning outcome.

Stage three then becomes a shopping list rather than a creative act. You work back from the task and ask what it demands. That is usually a short, dull and surprisingly specific list, and it tends to be shorter than the one a coursebook unit would have given you.

A worked classroom example

A six week evening course for eleven adults at B1 in a language school in Seville, two hours a week, all of them working in customer facing roles in a call centre that has just added an English speaking line. The coursebook unit on the shelf covered travel and holidays.

The instructive part is what the sequence removed. Planning forwards from the coursebook would have produced six competent lessons on travel, and the group would have finished the course no readier for the call they were afraid of. The removal is the method working, not a shortcut around it.

One caution from the same course: the week six recording was the only piece of evidence that carried real weight, and that is a known risk of the framework. A single culminating task is fragile, because one learner with a cold or a bad night loses the whole record. The two interim recordings existed to guard against that, and they are the part of the design most often left out.

Commonly confused terms

Where it comes from, and what it does not claim

The idea that planning should start from ends rather than means is older than the name. Ralph Tyler set it out in 1949 in a four question rationale for curriculum planning that begins with the purposes a school seeks to attain. Wiggins and McTighe named it, gave it a template and made it usable at unit level in Understanding by Design, first published by ASCD in 1998 and revised in 2005.

Two parts of their framework are worth knowing and are often dropped in summaries. The first is the six facets of understanding, which is what stage two is supposed to assess against: the capacity to explain, interpret, apply, shift perspective, empathise and self assess. The authors are explicit that not all six are used every time, and that performance tasks built on them are culminating tasks for a unit rather than something a daily lesson carries. The second is that they do not recommend applying the full three stage process to an isolated lesson. The unit, not the lesson, is the design object, because an essential question is meant to be revisited over time rather than answered before the bell.

The honest caveat is about evidence. Backward design is very widely adopted and has a substantial practitioner literature behind it, including a peer reviewed account in CBE Life Sciences Education describing how graduate and secondary science teams used it to rebuild lesson plans under a National Science Foundation project. What it does not have is a body of controlled trials showing that courses planned this way outperform courses planned another way. It is best understood as a discipline for planning rather than as an intervention with a measured effect size, and a page that tells you otherwise is overselling it.

The second caveat is practical. The template can become the work. A three stage plan written for every unit of a general English course, complete with essential questions and transfer goals, is a large amount of paper for a teacher with four classes and no planning time. The part that survives contact with a real timetable is smaller: name the result, write the evidence, then plan. Everything else in the framework is optional scaffolding around those three moves.

Frequently asked questions

What is backward design in simple terms?

It is planning in reverse. You decide what learners should be able to do at the end, then decide what would count as proof they can do it, and only then plan the lessons that get them there. The name refers to the order of planning, not to anything about the teaching itself.

What are the three stages of backward design?

Identify desired results, determine acceptable evidence, and plan learning experiences and instruction. The three come from Wiggins and McTighe’s Understanding by Design framework, and the requirement that ties them together is alignment: what stage one names must be what stage two assesses and what stage three teaches.

Is backward design the same as Understanding by Design?

Not quite. Understanding by Design, often shortened to UbD, is the wider framework Wiggins and McTighe built, including the template, the six facets of understanding and the design standards. Backward design is the planning sequence at its centre. In everyday staffroom use the two names are treated as interchangeable, and little is lost by that.

How does backward design work in a language classroom?

Stage one is usually written as a can do statement of the kind the CEFR uses, because language courses already describe ability that way. Stage two is a performance task that resembles the real situation, such as a phone call, an interview or a written enquiry. Stage three is then the lexis, structures and skills work that the task turns out to require, which is often less than a coursebook unit would have covered.

Is backward design the same as teaching to the test?

No, although they can look similar from outside. Teaching to the test takes an existing exam and works back from its format. Backward design starts from what you want learners to be able to do in the world and then designs evidence for that. The two coincide only when the exam happens to measure the thing you actually wanted.

What are the criticisms of backward design?

Two are worth taking seriously. Its evidence base is adoption and practitioner report rather than controlled comparison, so it is a planning discipline rather than a measured intervention. And the full template is heavy for a teacher with several classes, which in practice means the paperwork gets abandoned before the idea does. Keeping the three moves and dropping the forms is a reasonable response to both.

What eliciting is for

The British Council’s guidance sets out three premises behind the technique: that a class collectively holds a great deal of language and world knowledge which needs activating, that new knowledge is usually built on what learners already have, and that questioning assists in self discovery, which makes information more memorable. The same guidance quotes the definition given in the Dictionary of Language Teaching and Applied Linguistics, “Techniques or procedures which a teacher uses to get learners to actively produce speech or writing”, and notes that this is wider than vocabulary alone.

That width is the part most trainees miss. A teacher can elicit vocabulary and grammatical form, and can just as usefully elicit ideas, feelings, situations, associations and memories. The British Council’s teaching knowledge database entry describes elicitation as a learner centred technique for teaching grammar and vocabulary, with the first conditional as its worked example: the teacher puts examples on the board and writes “We make the first conditional in English with…?” rather than stating the rule.

The diagnostic use is the one worth protecting. Eliciting tells a teacher what the learners know or do not know before the plan is committed to, which makes it the cheapest form of assessment available and a natural companion to needs analysis. A teacher who elicits at the top of a lesson and finds the class already has the target language has saved twenty minutes and learned something a lesson plan could not have told them.

A worked classroom example

A B1 class of fourteen adults, a reading text about commuting, and one item the text depends on: exhausted. The teacher has ninety seconds to get it into the room. The sequence below is the one that works, and the column on the right is what makes it work.

Two things make the difference between this and the version that dies. The first is that the situation comes before the question. The second is step three: the teacher had a narrowing prompt ready and used it after one exchange rather than asking the same question four more times in a hopeful voice. The British Council’s own advice is blunt about this, warning teachers not to “pull teeth” and to treat prolonged silence or wrong answers as a signal that input is required.

Commonly confused

The first two rows account for most of the confusion on teacher training courses. A trainee told to elicit more and concept check more frequently does both at once, producing a question that neither draws out language nor tests meaning. Keeping the two moves in order, elicit then check, fixes it in a lesson.

Where the idea sits, and the caveat that matters most

Eliciting is old enough that nobody owns it, but its analytical home is the study of classroom discourse. Sinclair and Coulthard’s 1975 description of the English used by teachers and pupils named elicitation as a class of act within the three part exchange of initiation, response and feedback, which is still the standard way of describing what happens when a teacher asks and a class answers. Long and Sato later separated display questions, which ask for what the teacher already knows, from referential questions, which ask for what the teacher does not, and found classroom talk dominated by the first. Brock’s 1986 study in TESOL Quarterly then showed that raising the proportion of referential questions produced longer and syntactically more complex learner responses.

The practical reading of that literature is not that display questions are bad. Eliciting a known word from a class is a display question and it works. The reading is that a lesson made entirely of them limits what learners produce, which is why eliciting belongs alongside referential work rather than replacing it.

The caveat that matters most in an international classroom is cultural, and the British Council states it plainly. An open invitation such as “Who can tell me something about…?” is met with silence in many settings, and the learners are then wrongly labelled as ignorant or shy when the reason is that volunteering information, or standing out from the group either as a success or a failure, is not done. The recommended corrections are practical: nominate rather than wait for volunteers, so that no learner chooses to stand out; give thinking time, and allow an answer to be written down first; ask questions with no right answer at the lead in stage; and encourage rather than correct, because confidence and not accuracy is what is being built at that moment.

The other reason to elicit is arithmetical. Every answer a learner supplies is an answer the teacher did not have to say, which is why the technique is the fastest available lever on teacher talking time and student talking time, and why it appears in the presentation stage of almost every presentation, practice, production lesson a trainee is asked to plan.

Frequently asked questions

What does eliciting mean in teaching?

Eliciting means drawing language, ideas or knowledge out of learners instead of presenting it to them. The teacher provides a prompt, such as a picture, a situation or a gapped sentence, and the class supplies the word, the rule or the idea. It is used to make learning more memorable, to keep the classroom learner centred, and to find out what a group already knows before teaching it something it does not need.

What is the difference between eliciting and concept checking questions?

They run in sequence and do different jobs. Eliciting gets the item into the room by asking the learners to produce it. Concept checking questions come afterwards and test whether the meaning has actually landed, usually through short closed questions with yes or no answers. If you elicit and never check, you have the word without knowing it is understood. If you only check, something else had to supply the word first.

Is eliciting the same as Socratic questioning?

No, and the British Council draws the line directly. Eliciting is designed to find out what learners know. Socratic questioning is designed to lead learners to a conclusion which only the teacher holds. The two can look identical from the back of the room, because both consist of a teacher asking a series of questions, but the purposes point in opposite directions and so does what the teacher does with an unexpected answer.

How does eliciting reduce teacher talking time?

Mechanically. Every item a learner supplies is an item the teacher did not explain, and the explanation is usually the longest turn in the exchange. The effect is not only arithmetical: a class that expects to be asked stays alert in a way a class that expects to be told does not. Eliciting is the most reliable single adjustment a teacher can make to the balance of talk in a lesson.

What should you do when eliciting produces silence?

Give input rather than repeating the question. Prolonged silence usually means the context was thin, the question was too open for the level, or volunteering is not something this group does. Narrow the prompt, nominate a learner by name, allow thinking or writing time, or simply supply the item and move on. The British Council’s advice is not to pull teeth: an elicitation that has failed twice has told you something useful and should be ended.

Can you elicit from beginners?

Yes, with tighter questions. At lower levels open ended questions should be avoided, because learners are unlikely to have the language to answer them to their own satisfaction, and the attempt produces frustration rather than production. Guided questioning works instead: yes or no questions, choices between two options, gapped sentences on the board and heavy visual support. Learners can also elicit from each other, which shifts attention away from the teacher and builds confidence.

What the two terms actually measure

Teacher talking time and student talking time are observation categories before they are anything else. They were designed to be counted by somebody sitting at the back of a room, which is why they are coarse: they record who is speaking and nothing about whether the speaking is any good. The table below sets out what each term covers and what it leaves out.

The British Council’s teaching knowledge entry puts the definition plainly: teacher talking time is the time that teachers spend talking in class, rather than learners, and student talking time is the time learners spend talking rather than the teacher. Both, it notes, are useful categories for observation of teaching or for self reflection about teaching. That is the honest scope of the pair. They are lenses, not verdicts.

How it is used in practice

The arithmetic that made TTT a standard training topic is simple. Steve Darn, writing for the British Council, puts it this way: if the teacher talks for half the time in a 60 minute lesson with 15 students, each student gets only 2 minutes to speak. Nobody learns to swim in two minutes a week, and that is the whole argument in one line.

The argument on the other side is equally real. The same source lists the forms of teacher talk that earn their place: personalised presentations, questioning, natural conversation and storytelling. In a monolingual classroom the teacher may be the only source of natural spoken English in the room, and roughly tuned teacher speech is comprehensible input rather than dead air. Silence is also doing work. Darn notes that it provides processing time between instructions, during explanations, while waiting for a student to respond, and during monitoring of activities, and that prompting or rephrasing is often counterproductive when the learner simply needs a moment.

So the practical use is diagnostic, not prescriptive. Declan Cooley, also writing for the British Council, describes the problem as leakage rather than volume: unhelpful teacher talk can leak out in many small, often unnoticed, ways, and he names four of them, which are repeating instructions, saying far more than the learner when receiving a contribution, asking long and elaborately polite questions, and echoing answers the class has already heard. None of those four is a decision a teacher makes. They are habits, which is why measuring is the first step and why Cooley says the first step to reducing teacher talk is simply being aware of it.

Reducing teacher talk is mostly a matter of changing the interaction pattern rather than exercising restraint. Group work with the teacher monitoring raises learner output at a stroke, because several learners speak at once. So does eliciting instead of presenting, demonstrating an instruction rather than narrating it, and cutting the echo. The stage where teacher talk reliably balloons is the presentation stage of a presentation, practice, production lesson, which is one of the standing criticisms of that shape.

A worked example: coding one recorded lesson

A teacher records a 60 minute upper intermediate general English lesson, fifteen learners, and listens back with a timer, marking every stretch of teacher talk into one of four categories. The total came to 26 minutes, or 43 per cent, which by the usual rule of thumb is unremarkable. The breakdown is where the lesson is.

The finding that matters is the last row, and it is not the one the percentage would have surfaced. Forty three per cent is a defensible total; four minutes of teacher talk inside a twelve minute discussion is not, because the discussion was the part of the lesson where the learners were supposed to be doing the work. This is the argument for coding the talk by category and by position in the lesson, rather than reporting one figure. A teacher told to talk less will usually trim the anecdote, which was the useful part. A teacher shown this table stops monitoring out loud, which costs nothing and returns four minutes of learner speech immediately.

Commonly confused

The confusion that causes most damage is the second one. Once a ratio becomes a target, teachers optimise for the target, and the easiest way to cut teacher talk is to cut the explanation and the anecdote, which were the parts a learner could not get anywhere else. The glossary entries on drilling and the affective filter describe the same trap from other angles: a measurable proxy quietly replaces the thing it was standing in for.

Where the idea came from, and the argument about it

The measurement predates the terminology. Interaction analysis in the 1960s, counting classroom moves with an observation schedule, established that teachers do most of the talking. Chaudron’s 1988 review of second language classroom research reports the first language finding that teachers tend to do most of the talking, about 60 per cent of the moves, and concludes that the language classroom studies confirm the standard finding of roughly two thirds of classroom speech being attributable to the teacher. Sinclair and Coulthard had already supplied the structural explanation in 1975: classroom discourse runs on an initiation, response, feedback exchange in which the teacher holds two of every three turns by design.

The terms TTT and STT themselves belong to communicative language teaching and to the initial training certificates that spread it. If the goal is communicative competence, and competence is built by using the language, then a lesson in which learners barely speak is failing on its own terms. Swain’s output hypothesis in 1985 gave that intuition a theoretical footing by arguing that producing language, not only receiving it, is what pushes a learner to process grammar rather than meaning alone.

Then the correction arrived. Thornbury in 1996 had teachers analyse their own classroom talk and found the useful variable was not volume but the kind of question asked and the kind of response invited. Cullen in 1998 made the case most directly: the profession had turned a reasonable observation into a slogan, and the right criterion for teacher talk is whether it is communicative in that classroom, not whether there is little of it. Walsh took the argument furthest, showing in 2002 that teacher talk can construct or obstruct learner participation depending on how it is used, and building a self evaluation framework so that teachers could examine their own talk against the aim of the moment rather than against a percentage.

Where that leaves a working teacher is unglamorous and sound. The figure is worth knowing once, because almost every teacher who measures it is surprised. After that the question is which category the minutes fall into and where in the lesson they land. A teacher who has never counted is probably talking more than they think; a teacher chasing a ratio is probably cutting the wrong minutes. Every technique named on this page has its own entry in the TEFL teaching methods and classroom techniques glossary.

Frequently asked questions

What is a good ratio of teacher talking time to student talking time?

There is no figure that holds across every lesson, and the ones in circulation, usually 30 per cent teacher and 70 per cent learner, are training heuristics rather than research findings. A beginners class needs more modelling than an advanced discussion class. The ratio is useful as a prompt to look at a lesson, and misleading as a standard to be marked against.

Is teacher talking time always a bad thing?

No. The British Council lists personalised presentations, questioning, natural conversation and storytelling as forms of teacher talk that earn their place, and in a monolingual classroom abroad the teacher may be the only source of natural English a learner hears. What displaces learning is unplanned talk: echoing answers, repeating instructions and filling silence.

How do I measure my own teacher talking time?

Record one lesson on a phone and listen back with a timer, marking each stretch of teacher talk as instruction, model, feedback or filler. The category matters more than the total. Most teachers find the overall figure is defensible and the proportion of filler is not, which is a far more fixable finding than being told to talk less.

What is the difference between teacher talking time and teacher talk?

Teacher talking time is a quantity, measured in minutes or as a percentage of the lesson. Teacher talk is the language itself and its quality, including how instructions are worded, how questions are framed and how feedback is given. Cullen’s argument in 1998 was that the second matters more than the first, and that a good lesson is not identified by a stopwatch.

How do I increase student talking time?

Change the interaction pattern rather than trying to speak less. Pair and group work with the teacher monitoring raises learner output immediately, because several learners speak at once instead of one at a time. Demonstrating an instruction rather than explaining it, eliciting rather than presenting, and waiting several seconds after a question all help.

Does teacher talking time work differently in online lessons?

Yes, and mostly against the teacher. Overlapping speech is harder to manage on a video call, so learners wait for a gap and the teacher fills it. In a one to one online lesson the split is naturally closer to even than in a class of fifteen, so the figure to watch is not the ratio but whether the learner is producing extended turns or only answering questions.
