Keeping Their Attention
So, just to make them do some work, and made them think about the ideas themselves. Talk amongst themselves about it. I think that just too much of me in the lecture just washes over them after five to 10 minutes. So they just need to have a break, think about the problem, do a couple of problems, talk amongst themselves... that seems to help, with both the variety of students in the class, but also just keeping them engaged. Keeping their attention.
