This article introduces a special, 20th anniversary issue of the Journal of Educational Change. The special issue edictoras have organized significant international contributions to theory-building into three areas. These concern diverse modalities of educators’ professionalism, debates around “getting to scale” with successful innovations, and conflicting views of social justice in schools and societies. Each of these areas comprises an independent vector of disagreement and debate, with differing meaning and interpretations based upon the cultures and histories of the given systems under review. The article asks what kinds of new research, and what kinds of affiliated theories in these topic areas, can best help to move the field of educational change forward in the coming years.
