Ever wondered how much students are learning from what intructors just covered? How do instructors know whether students are ready to apply what they have learned? Classroom Assessment Techniques (CATs) can help. 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.
