Howard Iver Thorsheim is Professor of Psychology and Neuroscience at St. Olaf College, Northfield, Minnesota, USA. In these blogs he offers his first-person insights into effective teaching techniques gleaned from a combination of scholarly research and over 40 years in the classroom.
The Challenge:
The challenge was how to promote cooperative thinking of team members doing psychophysiology, drawing from their richly diverse interests and ideas, and in the process to learn a “soft” skill that could transfer to later life.
The Solution:
I adapted a tried-and-true group process to help team members doing psychophysiology research identify diverse ideas and think about their group project in a cooperative way. (The technique can be scaled up to engage many teams simultaneously). The technique is called the Nominal Group Technique, first developed by DelBecq and Van de Ven (1975).* The reason for the word nominal is evident in Step 1.
Step 1. Each student in a team was given a stack of 25 or so Post-it® notes. Because each student is working alone at this point, they are a group in name only (i.e., nominally a group). Their homework assignment was to think independently about ideas and interests that came to mind for them, and jot down a few words identifying their idea or interest on each of the Post-it notes. Interaction comes in step 2.
Step 2. The next class, the team members gathered together near a whiteboard. In a round-robin interactive fashion, one at a time, the students placed their Post-it notes on the board: One person started by placing the top Post-it from their stack on the board; the second person placing their first Post-it note close or further away from the first person’s Post-it note, depending upon their sense of closeness of the ideas. So it goes with the other students, with the round robin continuing until all Post-it notes are placed on the wall. Step 3 is the convergence!
Step 3. Again in a round-robin fashion, students take turns with a non-permanent marker drawing dashed lines around clusters they observe, and jotting down their idea for a name for each cluster. The result from the large group of individual ideas or interests becomes a smaller cluster of related ideas. The result is more coherence of ideas, engagement, social cohesion, and team focus. It works every time in any team or group!
