The Handbook for Economics Lecturers

Group structure can have profound effects on what students achieve in terms of both group learning and task accomplishment. Jaques (2000, chapter 6) provides information on a wide range of alternative structures, with possible variations on each. It ranges from the minimal-size Buzz groups, where students turn to their neighbours for discussion (often used in lectures to provide a break), to other forms of direct communication such as 'Snowball', 'Fishbowl', 'Crossover', 'Delphi' and 'Nominal' groups.
