Discussions You've Never Had is exactly that - around one hundred stimulating discussion topics in an exercise format that has never been used in EFL/ESL . Level? Low-intermediate to advanced, with no adaptation necessary by the teacher. What's new? The choice of topic is made by both teachers and students. This gives both teacher and student a feeling of being emancipated from course books. Discussions You've Never Had provide a refreshing alternative to the usual formula of: one topic + many related questions. Instead the formula is MANY TOPICS in the same exercise. Preparation? Once the Teachers Introduction has been read, the discussions require virtually no preparation. The exercises can be quickly dictated to students, thus no photocopies are required.
Duration? The discussions can be exploited both as warm ups or as 20-30 minute discussions. Anything else? Some of the discussions lend themselves well to practising particular grammar and vocabulary points. It is up to the teacher to decide whether to make such points a focus or not. If they do decide to exploit this element, then in this case the preparation simply involves reading the associated teachers notes.
