Here is the first lesson I've come across produced by NPR. Not surprisingly, it's terrific! After a discussion about what pupils know, and would like to know about slavery, the entire class listens to an NPR report. While they are listening, they take notes on a worksheet embedded in the plan. The program can be paused at any time for discussion. Excellent discussion questions are included, as is a meaningful writing task at the end of the lesson. Bravo NPR!
