I read the article and side with the teachers who suggest that real live lectures are better than recorded podcasts. I do feel that podcasts are better than notes only especially for the auditory learners (like me).
On a personal note I took a few classes that were offered on TV and on audio tape. The audio tape class was a waste of time. Reading the book was better than listening to a monotone lecture on cassette.( Sorry Dr. Hammer) The TV lecture was better than nothing, but without any real life person in front of you it was hard to see facial expressions, etc that you in person.
Finally and my main point of contention is that learning, especially in high school, SHOULD NOT BE ABOUT LECTURE!. I work very hard to engage my students and I limit my lecture time to less than 30 % of my total classroom time. Sometimes less IS more!
Here are the POD casts that I use with my class. I like information that is current and from respected sources (i.e. don't just listen to me class) . The other kinds that are valuable are shortened versions of Video that allows us to discuss.
