Ampère’s law

Tomorrow I’m covering we’re working on Ampere’s law in my calc-based general physics course. In preparation I was looking around at different ways to present it, and I realized that I was getting crabby about most of the presentations I … Continue reading

What if they don’t do it?

I’m still refining yesterday’s idea of having one day a week for assessment/review/integration in my General Physics II course. As often happens, I’m narrowing in on an idea/approach that I think could really help students learn, but there’s always the fear … Continue reading
