We all know that we learn best through doing, which means that effective training isn't just lecture, but also hands-only exercises. The thing is, there are different types of exercises that you can give in your class, with each serving a different purpose. In this talk, I'll review a few different types of exercises that I use in my courses, and discuss the trade-offs associated with each one. I'll also talk about how I present and then review exercises, and how I structure them in general, for maximum educational impact.
