In this part of the book there are three chapters addressing the theme of Teacher Learning Through and In Relation to Use of Curriculum Materials. My response to these chapters is in three sections: first, a short account of my perspective of the research setting in which these chapters are located; then a summary of each of the chapters, with suggestions about its contribution to knowledge in the field; and finally, a discussion of compelling themes suggested through my reading of the chapters leading to questions and theoretical issues to be prioritized in future research.
