This website is not for the beginning podcaster. It requires knowledge of host URL's and broadcast site URLs with no explanations as to how they work. I was never able to successfully produce a podcast. More knowledgeable folks may have better luck.
Although I don't plan on using any sort of podcasting in my classroom as a mode of instruction, I might consider using it as a way for students to make up missed lectures or instruction. This would hopefully help students reduce stress in that they would know that if they miss class, important information can be caught up online through listening to my podcast.
I found yodio.com for podcasting. This is a unique site in that you "call in" to record your podcasts and then can go back to add pictures. Not the best for making videos.
NEATO! In most classrooms the teacher will find podcast episodes for students to listen to or watch. Sets of laptops, iPods, netbooks or other devices can be loaded with podcast episodes so students can use them at their desks, on field trips, in the library, or at home.
I wouldn't use it for the classroom but it is an Interesting site and very useful, a place for me to store sites that I would later add to my blog for students to view.
