As a psychology graduate student I have the opportunity to teach an introductory psychology course. I'm hoping to take what I have learned here and start helping my students improve their rationality. Specifically, I'm planning to have the students read excerpts from Ch 22 & 23 of HPMOR as a fun and interesting way to start learning to think like a scientist. I'm hoping the community can assist me with possibly narrowing down the sections I'm going to have them read and consider possible methods of assessment. As of now, I know that I want to have the students analyze the methodology used by Harry in his two experiments from those chapters (Harry and Hermione testing spells and Harry and Draco "testing" the blood hypotheses), and I probably want to have students come up with their own hypotheses and methods to test them. Any help the community wants to provide is most appreciated.
You might want to crosspost this in http://reddit.com/r/hpmor - in addition to helping, it might make a good testing ground for anything you want to try.
Here's a probably relevant thread from that: What Experiments Should Harry Run on Magic?
