Material delivery
I have found the 15 minute mini-lecture concept to be very useful in adult courses. The challenge I've had with several of those brief lectures though is that many of them run over. By focusing on a 15 minute lecture, the material seems to be more interesting to the students and I actually have a hard time staying on schedule. But, the interactivity that comes with the briefer lecture achieves the ultimate goals of helping people learn the materials.
Gordon, you raise an interesting point. Taking information in smaller bites seems to help students absorb and get involved in it more easily. Having too much participation is a good problem to have, in some ways. :-)
Gordon,
I think it is easier for people to comprehend if the lectures are broken up. It is like playing a basketball game, it is best to break-up the game and focus on winning every five minute intervals.
