Students often enter introductory biology courses with misconceptions about evolution. For example, many students believe that traits arise when a species needs them or that evolutionary processes are goal-oriented. To address these and other misconceptions, we have developed an activity called "Boost Your Evolution IQ." Student groups compete against one another in a fast-paced, challenging quiz that is presented using PowerPoint. Questions get harder from beginning to end, and the stakes get higher: Each correct answer earns double points in round 2 and then triple points in round 3. Student collaboration throughout the activity helps reinforce the concepts in advanced students and allows struggling students to hear evolution explained in various ways. Further, the same misconception is often tested multiple times, allowing students to learn from their mistakes. This activity is useful as a review before an evolution exam or as a pre- and post-test. It may also be adapted for large classes using clicker technology. We provide a detailed explanation of the approach in the attached video (Supporting File S1).
