"Salman Khan talks about how and why he created the remarkable Khan Academy, a carefully structured series of educational videos offering complete curricula in math and, now, other subjects. He shows the power of interactive exercises, and calls for teachers to consider flipping the traditional classroom script -- give students video lectures to watch at home, and do "homework" in the classroom with the teacher available to help."
Easy video student response system. I can think of quite a few applications, exit tickets, flipped classroom, student response to reading material,etc. I'll write more next week after trying this.
Interesting comments about why the lecture is not going away from around 13:00-16:00 minute marker. Is the "flipped classroom" model still about efficiency rather than meaningful learning?
