It’s now been about eight years since AVI CHAI became interested in the field of personalized learning and the potential that this new model of education has to impact student growth and classroom experience. We concentrated our efforts on supporting a shift to blended learning, the strategic combination of teacher-led instruction and technology, as a way of creating more student-centered classrooms, where teachers are personalizing instruction based on data from technology platforms. Of course it now is satisfying to witness the adoption of these methods in many North American day schools. At the same time, we have learned a great deal about the most effective ways to approach this work to help schools actually make these changes.
