From student to teacher - whole topic revision

This is a fun task to do, that requires students to take over as the teacher. The teacher should have props available, ideally, a traditional teacher's morter board and down, and a clipboard. 

1) Students to recap as a class what they have learned in the hardware topic.

2) As a class, discuss what makes a question 'easy' and what makes a question 'harder'. Can they think of an example of each to illustrate their understanding. Students should have come up with e.g, What does RAM stand for? and State three storage devices? all have very specific answers that require no explanation. On the other hand, Why do computers have hard drives? and How could you compare three different hard drives in a shop before deciding which one to buy? all require more than a few words to give a full answer.

3) Ask students in pairs to come up with three easy questions and three harder questions. They should write down both the questions and the answers they expect to be given. 

4) Randomly pick a student, who should don the morter board and gown and be given the clipboard. Other students can test the teacher by asking them questions. After each answer, the class can decide if it was a full answer, a wrong answer or an 'okay but incomplete' answer. They can all do this quickly as a class using the 'thumbs up', 'thumbs down' and 'thumbs horizontal' method' and then any corrections can be made. 

This can be repeated until all topics have been covered.
