Using a case-study approach, the structures, interactions and cultures in four teaching groups at a New Zealand university are explored. The aim of the research is to better understand the potential of teaching groups for assisting academic development. To contextualize this work, the case-study outcomes are compared to research on microcultures. Similarities between strong teaching groups and strong microcultures are found, pointing to the potential of drawing on findings from microculture research. In particular, the use of social commons as a theoretical framework seems indicated, presenting teaching quality as a group and not just individual concern. Differences between the contexts stem from the sole focus of teaching groups on teaching compared to the combined research and teaching mandate of microcultures. As research often dominates teaching, the suggestion is made that teaching groups provide more suitable contexts for addressing teaching issues. The research recommends that organizational units in higher education should identify and analyse teaching groups and build on those groups in addressing teaching quality.
