The idea for this book emerged from discussions at the Research Study Conference
15 organised by the International Commission for Mathematical Instruction. The
study focused on professional education and development of teachers of mathematics
and brought together invited participants from around the world. The authors in
this book are a selection of presenters at that study conference, who subsequently
contributed chapters with examples and elaborations of tasks used in primary mathematics
teacher education. The authors first provided outlines that were subsequently
reviewed by the editorial group and then after a second review process revised to
produce the chapters you will find here
