The second phase of the lesson allows more focused (and therefore potentially more meaningful) explanations as the teacher takes on the active role to clarify and validate the student’s answer. First, all the answer for activities in the first phase are provided briefly and groups check their scores. These can then be recorded by the teacher for assessment purposes. Detailed reasons for the correct (and perhaps incorrect) answers can then be explained. Students record the answers on worksheets with complete sentences, the same as those distributed for discussion, so that the correct answers have a clear context. This serves to reinforce vocabulary and grammar key points, not only during a particular lesson, but also for the purpose of topic revision, actual TOEIC test preparation and end of term examination.
