The past simple is the English verb form used for an action or state completed at a finished time in the past. Most verbs form it by adding -ed, while a closed set of common verbs change their form instead. It is the ordinary narrative form of English and the first past form most learners meet.
The present perfect is the English verb form made with have or has plus a past participle, used to link a past action to the present moment. It covers experience up to now, a situation that began in the past and still continues, and a past event whose result matters now. It never takes a finished time reference.
Eliciting is the set of techniques a teacher uses to draw language, ideas or knowledge out of learners rather than presenting it to them. The teacher supplies a prompt, usually a picture, a context or a question, and the learners supply the answer.
