Only give them two or three minutes to work on a problem. That concentrates them and prevents them just talking about the football or whatever it is that’s on their mind. You need to keep changing the activity, rather than have extended activities. We want them to chat, but human beings won’t sit and chat about quantum mechanics for more than two or three minutes, they’ll get onto what they want for lunch. So it’s finding that balance. Two or three minutes seems to work about right.
Make the students think about the ideas themselves. Have them talk amongst themselves about it. If there’s too much lecturer in the lecture it just washes over them after five to ten minutes. They need to have a break, think about the problems, do a couple of problems and talk amongst themselves. That seems to keep them engaged, especially with the variety of students in the class. It keeps their attention. Lecture for five or ten minutes and use work sheets, which they pick up as they come in.
Students’ patience in thinking about this material is quite short sometimes. So don’t lecture the material for very long. Have a break and get them to do a problem. Do this after introducing the topic, once it’s getting a little bit more concrete, that is, when they can actually work through a problem.
Lecture for five or ten minutes and use work sheets, which they pick up as they come in. Let them work on the worksheets, then have a discussion and use a response devise, like their mobile phones, to feed back answers.
