Academic development recognizes the strengths of communities, such as communities of practice or learning communities, in providing academics with supportive environments for the development of teaching. The problem academic development faces is that not enough academics are involved in these communities. Instead of trying to interest academics in joining communities, this research looks at the existing contexts around academics, which it refers to as "teaching groups". It is proposed that every academic involved in teaching belongs to at least one teaching group, formed by colleagues teaching in the same course, degree or subject and that teaching groups form relevant contexts for engagement with teaching. The research investigates how teaching groups compare to communities and finds that less than half of teaching groups named by participants have strong community characteristics, indicating large space for improvement in the remaining majority of groups. The suggestion is made that identifying teaching groups across an institution might provide a promising starting point for engaging a majority of academics and working with these academics towards increased interaction on teaching in open and trusting collegial atmospheres.
