BL101: The growth of blended learning and Khan Academy go hand-in-hand. So it's only fitting that Khan is now offering a Blended Learning 101 course, in partnership with the Clayton Christensen Institute and the Silicon Schools Fund. The five-part course, which spans over 40 videos and resource guides, covers the basic principles (and lab models), questions about how to re-designing the roles of students, teachers and schools, and how to pick the right tools. Case studies look at how Summit Public Schools, KIPP LA, and Navigator Schools are shaking up the school formula.
