Dell, 1981
Reacting to the incredulity of his high school students that the holocaust could have happened under the apathetic eyes of a nation, a high school teacher decides to show his history class what it was like to be under Nazi rule, and how easily people conform in order to be part of a group. The experiment works much better than he expects, unfortunately. Most of the students are only too happy to follow their "leader" blindly, and some unexpected and terrifying behavior occurs as a result.
Based on a true story, this short book is appropriate for middle school and high school students, but interesting for adults as well.
Do you mean "The Wave" was a good movie? I'm checking out article, thanks for posting.
I read The Wave after you told me about it. I think I wasn't as impressed because I had just seen The Stanford Prison Experiment. Which, it turns out, was a fraud. Good movie though.
