My principal just sent around an interesting article from the Sacramento Bee (free registration required to read) about a teacher, Dylan Holcomb, who is using, among other tools, Google Earth and blogs to enhance his students' learning in English class. It is worth reading, and it strikes me as one of the few news pieces which portrays these web 2.0 tools in a positive, innovative light, rather than as a warning siren of a murky online community, ripe with lurking predators.
The bottom line is that the only way for such changes to become truly embedded in the educational system is for teachers, like Dylan, to take on leadership roles. The article states that he taught a packed workshop for his district's teachers, showing them digital tools, including everything "from sites to help generate surveys to free podcasts by professors at UC Berkeley and Massachusetts Institute of Technology." Numerous examples abound about teachers leading the change, including most recently by Dana, who presented to her faculty how to incorporate the use of wikis in the classroom.
