At the upper levels, students make more formal oral presentations, sometimes giving answers to specific homework questions, lecturing on a section of the textbook, or talking about readings they have done on their own. Occasionally, formal presentations are planned for a full class period, but more commonly the material can be covered in a few minutes. In addition to the merits of gaining experience with technical presentations, students usually are highly motivated to make a clear and careful presentation in front of their peers. During an effective theatrical production, the stage company forms a bond with the audience to create an atmosphere and to reinforce themes. Actors use such techniques as pace, intonation, facial expressions, and stage presence for dramatic effect.
Technicians work with such elements as stage design, lighting, and color.
As part of this activity, both actors and technicians must pay attention to audience reactions to learn how viewers react and why. While I certainly do not think of teaching as a form of entertainment, I think my style of teaching does have some elements in common with good theater. During lecture times, I try to read the faces of students to assess reactions, and I worry about pace, intonation, and expressions. At times, I may try a demonstration or other device for to make a point dramatically. Similarly, during lab times and when reading papers, I pay attention to what students are really thinking.
