Nice videos made by Mrs. Yollis and her 3rd grade students. She is a fantastic teacher who integrates technology and shares what she does really well. If you are an elementary teacher, her classroom blog is a great one to subscribe to with your RSS reader.
If you want to have your thinking pushed regarding teaching and technology, Ira Socol's blog here is one to subscribe to. This post is a prime example that challenges many of our assumptions about learning, school, and technology.
