Link: Spiral Notebook.
My favorite education related web site hands down is Edutopia, a production of the George Lucas Educational Foundation. In addition to producing a comprehensive web site on educational innovation, GLEF produces a companion magazine that is also superb and FREE.
Each week GLEF also publishes a newsletter and I noticed in today's edition that the GLEF now sponsors a blog. This blog is called The Spiral Notebook and contributors include a variety of experienced teachers and administrators. This is another welcome addition to my growing list of feeds I subscribe to using NetNewsWire.
I highly recommend any of the above resources. The overall design of the Edutopia materials is excellent and I love the content that focuses on educational change. Content is supplemented by extensive videos supporting new ideas. It's a practical, user friendly place to research best practices.
