Your instructional videos are top notch. Certainly better than mine. Your point about time is well taken and well understood by this classroom teacher. I've created several hundred multimedia instructional artifacts and I know well that you sometimes have to crank material out and go on.
The instructional screencasts I have made, like yours, are intended for reinforcement beyond classroom instruction. If a particular lesson seems difficult for the students, sometimes I'll fire up a screencasting application, whip out the tablet and headset and go at it. I have found that having some prepared text or graphics pre-made makes the video better and the lesson goes more smoothly. You have taken it to the next level by having the lesson thoroughly planned in advance.
My intent in the course is not to have teachers create top notch polished multimedia. I think that would be nearly impossible for a classroom teacher. I have noticed that having learned the research on effective multimedia has helped me improve, often in small ways, the quality of my multimedia. Many of the ideas here represent subtle shifts and, perhaps, reminders of what may already be obvious. Sometimes I can revisit my multimedia and tweak them before reuse.
Thanks for chiming in! It's great to have the input of such a skilled instructional multimedia craftsman.
