What can I say. Old dog, new tricks. I found this method very interesting but hard to grasp. I think I played it about 4 times and still had some difficulties. It is hard to unlearn the traditional method of problem solving that I have used for the last 30 years. Is this something new that you came up with, or is this a varient of how they teach solving for x nowadays? If this is something you came up with, this is sweet. Different ways to solve the same problems is the best way to reach as many of the learners as possible. Hats off, and I'll raise you a star for inginuity. However, I think you might want to take it slow, and use baby steps. I started to twitch on the last problem. If this is one of the newer ways to teach this topic, well, I suppose I should just sit back down and try not to hurt myself. That being said, It is a well thought out and well put together lesson,I just all that confident with the topics and tactics in a couple of places.
The only other thing that I might suggest is to put a little flavor into it. This is just my opinion, but I like to offer the viewer a bit of fun when navigating. Throw some clip art in, some sound files, maybe something on the visually silly side to lighten things up. I did like the whole regurgitation thing. That will wake them up.
No real technical issues. There were a couple slides that I wanted to go back on, but the buttons were not available. It was during the question and answer section where we were suppossed to write the equation down. I thought I had the right answer, I answered wrong and I wanted to see the equation again. Then at the end there was no end button. The show just looped around to the beginning and started again.
