Anytime we debate or discuss a major topic, I have students fill out this Debate doodlenote. It asks them to look for pros, cons, form their own opinion on the matter, and then gather excellent points for someone opposite them.
For example, we used this when discussing the death penalty (debate over cruel and unusual punishment). Students did research by gathering the pros and cons of each side. Then, they had to choose which side they agreed with. Did they think the death penalty was constitutional or not? Once they took a stance, they were paired with someone who had a differing viewpoint.
