A round-up of some recent (and not so recent) postings and musing on clickers in the classroom.
This posting is short and with some very specific hints and tricks to using clickers. It offers opinions (but not lots of discussion) on topics such as how many questions you should ask per class, what to do if students forget their clickers, and aligning questions with specific learning goals.
Why using clickers just for attendance is not the ideal.
It comes down to writing effective questions for different situations or objectives.
