Mixing it up with Khan: Thoughtful wrap-up to the Oakland Envision project with Khan Academy by Envision's former chief academic officer, Brian Greenberg. His point: it's not just about the videos, as charming as they are. Great tech can unshackle teachers to do the cool stuff, like meaningful projects. That's the best blend. There will be more "pilot" Khan schools this autumn. Stay tuned for the full list but we're betting at least one will pop up in Oakland.
