In this article, Betsy Potash shares the frustration she experienced as a student when working on group projects. She struggled with being a good listener and with a tendency to dominate the group projects. Teachers had not taught her how to work well in a group. During her first year as a teacher, Betsy attended a faculty retreat where she learned about the Harkness method of discussion--invented and pioneered at Phillips Exeter Academy (New Hampshire), and named after philanthropist Edward Stephen Harkness. As she read about the roundtable discussion method--in which the teacher acts as a guide for the discussion and works mainly to help students learn to ask good questions, share the air, provide support for their opinions, and navigate through distractions and accidental domination--she became more and more interested. She decided to launch a Harkness experiment in each of her classes. This article discusses how using the Harkness method helped unleash an understanding of the power of group dynamics in her classes.
