I have found that a very useful way off interacting with students, while at the same time, building a rapport and an environment of trust, is to tap into the expertise of students in my classes. While I am the most expert on our topic, oftentimes I have students who have real-life and work place experiences that help to illuminate key points in the course. So, when I pinpoint subject-matter experts within the student roster, it (a) helps to teach by using anecdotal information, (b) create a defined role of importance for many students, and (c) provides non "SME" students with an immediate connection with a peer. This helps to "gel" a class and to enrich the learning experience.
