This paper reports on a study undertaken to identify the strategies and models used to facilitate curriculum change within teacher education institutions. Findings indicate three main approaches, which we name the "resource development", "action research" and "contextual change" models. A new model that combines the best features of each is proposed. In this paper we provide a brief overview of the three models, a rationale for the new model being proposed, and a discussion of the systems theory concepts underpinning the model. It is our contention that the Mainstreaming Change model provides a structure for change to occur simultaneously at a number of levels within a teacher education system. We conclude by discussing some issues that may facilitate or limit the effectiveness of the model in practice. (Contains 4 figures.)
