How does the work get done?

Once we have all agreed that schools owe it to their students to engage them in different ways and shift to a more student centered classroom, what happens next? It takes so long to get "buy in" from all of the teachers, do we have to wait for everyone to be on board, or can we just start.

I really feel like I need to get the infrastructure up to speed to support the usage. Nobody should have to struggle with the equipment.
