Yeah, more tests, please.

I have to say that I hoped this was/is true. I used to give more tests than the average teacher in the UK. Certainly in the schools I taught physics in. I just felt, rather than knew, that it was good - for physics learning. I used as wide a variety of testing as I could. Short, ten question tests, half termly exam practice questions etc.

What is your view about testing, given this evidence?
