Five minute videos explaining how to use specific tools in a classroom setting. It's a great first stop if you haven't used a tool or want to hear from an educator about how it could be used in a classroom. 

If you are looking for examples of teacher OR student blogs, this new Edublogs directory can be handy. Categories by content area, as well as a category for students (student blogs in content area sections too). Great place to look for ideas of what you might do in your classroom.

A middle school classroom teacher reflects on the tools they use in their classroom and the fact that it's the learning and how you empower students to create, think, evaluate and find resources that is key, not the tool itself.  Great reality check when it comes to integrating technology in the classroom.

Biology teachers, check out the lovely graphics linked from this site. Might be useful for Health classes, psych class, bio, anatomy, etc.  (from twitter)

Listen to the actual podcast, 14 minutes. Yes, it's from 2006. Yes it's aimed at higher-ed. However, the concepts, applications, ideas are all valid, esp for 7-12. Make podcast tours of town, local sights, etc. with historical context or other curricular relevant information and making them available to others to download - even for small town locales.

Excellent blog post with ideas for teacher podcasts and student podcasts. See what you think!

Check out the list of student and class podcasts by grade span, then check out the subject specific podcasts as examples of what might be done.  

Great page of links to resources on how to use Google in the classroom with students. LOTS of links. You will need to scan to see what you actually are looking for. Interesting graphic of how Google Apps components can work for a student over the course of their education.
