If you look over this excellent and helpful document on Lesson Planning and the famous “Plenary “, you’ll see that it says that:
“There are a number of reasons why the plenary tends to be the least successful part of the lesson. Sometimes teachers have not planned it sufficiently thoroughly or don’t allow enough time for it. Sometimes the teacher does all the work instead of making sure that the pupils are as active in this part of the lesson as they are in the starter, perhaps summing up without giving the pupils an opportunity to articulate what they have learned.”
Also, OFSTED say that it is looking for the following:
“…plenary sessions in lessons are used flexibly and geared to giving pupils an opportunity to say what they have learned.”
So I found a brilliant website that helps with this challenge. Visit FortheTeachers Blog and you’ll find some very helpful (and printable) ideas!
