The only thing here I take MAJOR issue with is the idea of requiring teachers to submit one lesson a week involving iPads. Maybe a good alternative would be creating a virtual space where teachers can choose to share those lessons with others to help them generate ideas for their own lessons. We definitely do need a careful, structured, and thoughtful approach to integrating new technologies into our classrooms, especially if doing so becomes increasingly expected by administration and the board. "Let them have iPads" isn't really a sustainable pedagogy or leadership strategy.
A great example of why we need to exercise our own professional discretion in how, when, and why we use social media for learning.
