Podcast are a wonderful teaching tool for educators to use in the classroom, audio and video podcast are available. I see podcast more beneficial to university, high school, and middle school students. Video podcast can be used by students taking a web-based course so they have visual examples of the lesson. Professors or teachers can assign students to download lectures from different universities.
Itunes U has every subject on every level of learning. Teachers could assign history lessons to be view on a video podcast or watch an example of a statical problem being solved for math class. There are video podcast for students learning another language or if taking an art class you can find examples on drawing different subjects, use of this tool is endless.
Although I do feel it is more beneficial to older students there is plenty of material for elementary school students. Teachers could assign students to download and watch mini field trips then write a report on what they learned. Students could listen to certain stories and write a book report. The material found on itunes U is free to use, as an educator I plan on taking advantage of this resouce.
