I'm just about to start lecturing the tutorials for a linear algebra class next week. The prof that is running the course taught it to me 4 years ago and is the reason I'm now in grad school. She did more or less the same thing that you mention, and it definitely works. I remember all of this material from back when I took the class; it's still familiar and I use it all the time. But despite being very useful for a half to two-thirds of her students, there is always about 1/3 of the class who does terrible in this course. How did you get these people to keep up? Anyway, I'm glad you posted this. It's a good pick-me-up motivator as I'm about to be trying to do the same thing!
