The Khan Academy started as a tutoring program and has now become a model for the "flipped classroom."  His work is being featured in several of our schools, as we examine the impact on students.  Check out the 60 minutes video at the link below.  If you want more information, you can also see Mr. Khan's famous "TED Talk."  You can find all TED talks at ted.com.
