Khan Academy, best known for its free online library of video tutorials, is using the summer months to offer in-person teacher trainings in places like Chicago, New Orleans, and Redwood City, California. The workshops are integrating what teachers and Khan Academy staff have learned over the past few years while experimenting with different ways of integrating videos and Khan assessments into classrooms.
