Graduate students are often employed as teaching assistants (TAs) in the larger universities, meeting students in small tutorial groups.

The setting allows an enterprising TA to open some eyes with good examples and questions. For an illustration, check out this amusing blog entry "What I taught students in my first TA session", written by an anonymous American grad student.
