I teach Philosophy at Bentley University in Waltham, MA, and my favorite subject to teach is Critical Thinking. This file contains all the course materials for my Critical Thinking class, including lectures, quizzes and tests. It covers cognitive biases, fallacies, basic logic, probability, issues with the media, inductive logic, science vs. pseudoscience and a handful of other topics. I think that High School students could easily handle the material.
