Belbin team role self and observer perceptions were applied to a large cohort (145) of Geography, Earth and Environmental Sciences undergraduates in a module assessed through two separate group projects. Students self-selected groups for the first project; for the second, groups were more "balanced." Results show slight improvement in group performance compared with that of previous years, with a significant increase in first-class grades. No evidence was found linking group balance to performance; however, students recognized the value of their Belbin report when entering the job market. Belbin usefully contextualizes regularly occurring group work issues and provides students with ways of managing these issues. (Contains 4 tables and 3 figures.)
