5.1 Group structure

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.
