Part 2 of the TED Radio Hour episode Building A Better Classroom.
In 2004, Salman Khan, a senior hedge fund analyst, began posting math tutorials on YouTube for his cousins. Six years later, he's posted more than 3,200 carefully structured educational videos offering complete curricula in math and other subjects.
In his TEDTalk, Khan demonstrates the power of interactive exercises and calls for teachers to consider flipping the traditional classroom script. He suggests giving students video lectures to watch at home, and says they should do "homework" in the classroom with the teacher available to help.
