Session 5.1: Making Lectures Interactive (AM)

Diane Bunce, a professor of chemistry at Catholic University, is introduced. Diane will lead the day's workshop on how to make large lectures more interactive.

The day will begin with a lecture given by Bunce to an actual class at UMASS, a section of second-semester general chemistry now being taught in summer session. Before proceeding to the lecture hall, participants are asked to monitor both their own responses and those of students to the lecture. Bunce asks: What about the lecture draws the room into the material and helps the class get a better grasp on it? What DOESN'T seem to "work" during the class period?

With these charges, participants attend the 9:30 section of *******. (A video of this lecture is available for viewing. Briefly, the lecture focuses on a range of concepts such as kinetic molecular theory, intermolecular forces, dipoles, sublimation, and molecular bonding. During the lecture, Bunce illustrates these concepts by asking students to "act" as molecules and perform their functions; by asking students to engage in informal group work [i.e., turn to your partner and discuss]; and by projecting on the wall computer simulations of molecules interacting under various conditions.)

The class ends at 11:00 p.m. and workshop participants take a break until 11:30.

At 11:30, participants reconvene to discuss why lectures should be interactive. To make the case for interactive lectures, Bunce shows a video of three different instructors whose lecturing styles range from "straight" to "interactive" and asks participants to evaluate how much comprehension they gain from listening to each instructor. Discussion of this video and what it exemplifies ends at 12:00.
