In a huge lecture hall, it can be easy for students to fade into the crowd while professors rhapsodize about abstract academics. But that scenario is no fun for anyone -- teachers or students. And passive listening rarely leads to a lifelong love of learning. Instead, psychology professors at the University find entertaining and unusual ways to engage their students, whether they are teaching a class of 20 or 200. Meet three professors who are inspiring students to learn -- and enjoying themselves in the process.
