Higher education calls for reform, but deeper knowledge about the prerequisites for teaching development and pedagogical change is missing. In this study, 51 university teachers' experiences of supportive or constraining factors in teaching development were investigated in the context of Finland's multidisciplinary network. The findings reveal that the supportive factors in teaching development arise from the nature of the development itself, i.e., from the teachers' opportunities to act as active agents in an authentic development process. Furthermore, the circumstances of the development also play essential roles (both constraining and supportive) in teaching development. Such support, at its best, will come when teachers and others view teaching development in the university context as being valuable and rewarding, and when teachers are encouraged by management and are supplemented with the necessary equipment, tools, and networks they need to do their job. Increasing interaction between the institutional levels can make educational development successful.
