As I've said many times:
If a teacher gets it, a classroom changes. If a principal gets it, the whole building begins to change. If a superintendent gets it, the whole district begins to change. [And, if state or federal policymakers get it, the statewide or nationwide climate begins to change.]
Seems obvious, right? So why are so many government / corporation / foundation educational technology reform initiatives (money, time, training, energy, vision) focused on teachers, who at best are usually informal leaders, rather than formal leaders such as principals and superintendents? Do they want systemic change or just something they can tout for public relations purposes?
I'm all for investing in students and teachers when it comes to educational technology. But if we don't also set aside some dedicated resources for formal leaders, the kind of changes we need are never going to happen.
