TRAJECTORIES OF PARTICIPATION AND PRACTICE: SOME DYNAMIC ASPECTS OF THE THINKING PRACTICES OF TEACHING, EDUCATIONAL DESIGN, AND RESEARCH

ByJames G. Greeno

The chapters by Stein, Silver, and Smith and by Lampert present innovative and stimulating perspectives in which they focus on participation by teachers in practices of teaching and discourse about teaching. Both of these chapters have significantly advanced my understanding of practices and communities of teachers, and also have advanced my understanding of the theoretical concepts of participation, communities of practice, and personal identity. I hope that in these comments I can convey my strong enthusiasm about both of these contributions, and can also communicate a framework that I believe highlights some of the conceptual advances that they provide.
