Ever wondered how much students are learning from what their instructor just covered? How do instructors know whether their students are ready to apply what they have learned? Classroom Assessment Techniques (CATs) can help instructors find out. CATs are simple and often ungraded in-class activities that help instructors and students alike monitor the teaching-learning process in real-time. In this workshop, participants will have the opportunity to experience and discuss CATs and will gain practice selecting and integrating appropriate CATs into their teaching.
