I attended a workshop on team-based learning 2 years ago and almost immediately started thinking about how to use some of the components in my classroom. I adopted permanent, instructor-selected teams (for labs, quizzes, science fair), and group quizzes. The group quizzes have been particularly effective; I developed my own re-usable version of the IF-AT scratch sheets. Students have the opportunity to discuss and debate answers with their peers, gain immediate feedback on the correct answers and have fun doing it! I introduce the quiz to students in this short video.
