Sometimes I and students would see a different goal of a class. I will make them practice one thing and they would think about something else.
I need students to practice a Swing Out a lot. But just practicing is boring even if I give them tips and techniques to work on. Spending more then 1 class on swing out might not be that fun.
Instead I teach them Swing Out footwork variations.
Students get busy thinking about rhythms and steps, but at the same time they do hundreds of Swing Outs in a single class. And they make Swing Out work with every partner, because they are learning and focusing on footwork.
They might and will forget lots of stuff what I teach, but making them practice some basics/moves/rhythms will make them better.
