The argument in this paper is that teachers' interpretations and theories about what works in classrooms, can and should constitute the basis of change. Teachers have the capacity to engage in practical reflection through collaboration that enriches their sense of what is feasible and possible as well as transforming their understanding of those realities. Critical reflection, however, requires various forms of assistance, and in this case it occurred through the provision of a paradigm, the Cogan (1973)/Goldhammer (1969) notion of clinical supervision.
