Large-scale school change often involves both complex systems (lots of different people, schools, organizations, etc.), as well as, things that teachers have never experienced themselves.
That's why schools need a model of deliberate leadership for school change. One such model is Lead4Change.
Lead4Change grew from early learnings from the Maine Learning Technology Initiative (MLTI) about what strategies successful schools were using, and were often missing at schools having less success. Working with a variety of schools designed to motivate students, it became clear that the lessons generalized nicely to all kinds of school change, not just 1to1 laptop and tablet initiatives.
This 16 minute video provides an overview of the model.
My school district is applying this model to our technology initiatives, MLTI & Advantage 2014, and several districts, including mine, is using it to help shape our work around Customized Learning.
