1 Teaching with Tasks for Effective Mathematics Learning

2 MATHEMATICS TEACHER EDUCATION VOLUME 9 SERIES EDITOR Andrea Peter-Koop, University of Oldenburg, Germany Patricia Wilson, University of Georgia, United States EDITORIAL BOARD Andy Begg, Auckland University of Technology, New Zealand Chris Breen, University of Cape Town, South Africa Francis Lopez-Real, University of Hong Kong, China Jarmila Novotna, Charles University, Czechoslovakia Jeppe Skott, Danish University of Education, Copenhagen, Denmark Peter Sullivan, Monash University, Melbourne, Australia Dina Tirosh, Tel Aviv University, Israel SCOPE The Mathematics Teacher Education book series presents relevant research and innovative international developments with respect to the preparation and professional development of mathematics teachers. A better understanding of teachers cognitions as well as knowledge about effective models for preservice and inservice teacher education is fundamental for mathematics education at the primary, secondary and tertiary level in the various contexts and cultures across the world. Therefore, considerable research is needed to understand what facilitates and impedes mathematics teachers professional learning. The series aims to provide a signi fi cant resource for teachers, teacher educators and graduate students by introducing and critically re fl ecting new ideas, concepts and fi ndings of research in teacher education.

5 Acknowledgements This project was funded by an Australian Research Council Linkage Grant, and we are grateful for the support of the ARC. We also acknowledge the contribution of the Department of Education and Early Childhood Development (DEECD, Victoria, Australia) and the Catholic Education Of fi ce Melbourne (CEOM, Australia) who assisted with funding, provided links with schools, and offered helpful guidance throughout the project. In particular, we thank Nadia Walker and Helen Gist (DEECD) and Gerard Lewis and Janeane Anderson (CEOM) for their roles in this. We thank the three clusters of schools and their cluster leaders, Merging Minds Cluster (Jan McCluskey): Armadale Primary School, Hawthorn Secondary College, Lloyd Street Primary School, Malvern Central School, and Toorak Primary School; Berwick South Cluster (Peter Sanders): Berwick Fields Primary School, Brentwood Park Primary School, Hallam Valley Primary School, Hillsmeade Primary School, Kambrya College, and Timbarra Primary School; and Geelong Cluster (Peter Caddy): Our Lady Star of the Sea Ocean Grove, St Aloysius Queenscliff, St Anthony s Lara, St Ignatius Secondary College, St Margaret s East Geelong, St Therese Torquay, and St Thomas Drysdale. There was a group of teachers within the clusters who volunteered to develop and teach extended units of work as the research team studied their teaching. We are particularly grateful to these teachers. They were Shaye Bradbury, Elizabeth Campbell, Anthony Cavagna, Robyn Frigo, John Hassett, Alison Jordan, and Chris Powers. We also thank Helen O Shea who was a Senior Research Fellow on the project for the last two years and who made a major contribution to the data on students which are reported in this book. We acknowledge too the work of Anne Roche in data collection, professional development leadership, and research assistance. We also thank Orit Zaslavasky, Ron Tzur, and Irit Peled who contributed to the project when visiting Monash University. Meredith Begg and Leicha Bragg assisted with v

6 vi Acknowledgements the documentation of lessons and the development of the website, while Alison Jansz-Senn and Nike Prince undertook important administrative and research work in the earlier years of the project. Wendy May assisted us greatly in bringing this book to fruition with her management and editorial skills in the later stages, while Sheryl Sullivan assisted with re fi ning the tasks included in the fi nal chapter. Sarah Ferguson and Richard O Donovan completed PhDs which focused on aspects of the project involving low attaining students and the challenges teachers experience with using tasks effectively, respectively.

7 About the Authors Barbara Clarke is an Associate Professor in Mathematics Education at Monash University (Peninsula Campus) where she teaches primary pre-service teachers. Barbara has considerable experience in conducting and supporting research and directing or supervising major research projects and contracts. The major focus of her writing and research has been concerned with mathematics teachers, their practice, and their professional development. Doug Clarke is a Professor of Mathematics Education at the Australian Catholic University (Melbourne), where he directs the Mathematics Teaching and Learning Research Centre. In recent years, Doug has worked on four Australian Research Council grants, focusing on integrating mathematics and science, the role of tasks in mathematics learning, encouraging student persistence while working on challenging tasks, and providing appropriate support for teachers implementing national curricula, respectively. Doug s professional interests include young children s mathematical learning, using mathematics to explore current events and students interests, the role of task-based assessment interviews with students, problem solving and investigations, manageable and meaningful assessment, and the professional growth of mathematics teachers. Peter Sullivan is a Professor of Science, Mathematics, and Technology at Monash University. His main professional achievements are in the fi eld of research. His recent research includes four Australian Research Council grants funded projects. He is an author of the popular teacher resource Open-ended maths activities: Using good questions to enhance learning that is published in the US as Good questions for math teaching. Until recently he was chief editor of the Journal of Mathematics Teacher Education, was immediate past president of the Australian Association of Mathematics Teachers, was the author of the Shape paper that outlines the principles for the development of the Australian Curriculum in Mathematics, and was the author of the 2011 Australian Education Review on research informed strategies for teaching mathematics. vii
