Introduction: The Learning and Development of Mathematics Teacher Educators

Research into the learning and development of mathematics teacher educators (MTEs) is an emerging field that offers many opportunities as well as challenges. This book provides an opportunity to gather together international perspectives on MTE learning and development and identify future research directions. Chapters in the book address three major themes: (1) the nature of MTE expertise, (2) learning and developing as a MTE, and (3) methodological challenges in researching MTE expertise, learning, and development. Two commentary chapters provide critical reviews of the research approaches and findings reported in the main body of the book. This Introduction chapter outlines the rationale for the book, briefly reviews key research issues and questions within the three themes, and gives an overview of the theoretical and methodological contributions made by each chapter.
