The school day is already jam packed. How do you find time for networking?
Administrators have to facilitate change. A lone teacher can do it, but it's hard to sustain.
Administrators have to decide this is valued for the whole school community, and they have to give
teachers time and freedom to learn, experiment, and play. Lots of teachers are doing it on their
own, but it can be exhausting. That's classroom 2.0, not school 2.0.
