Ghislaine Gueudet is professor in mathematics didactics. She works at the University of Western Brittany in France. She is co-director of the CREAD (Center for Research on Education, Learning and Didactics). Her research concerns the interactions between teachers and resources (with a specific focus on online resources), and their consequences in terms of professional development. This theme lead her to develop, together with Luc Trouche, a documentational approach to didactics.Web page: http://cread.bretagne.iufm.fr/spip.php?article447Birgit Pepin is professor of mathematics didactics at Sør-Trøndelag University College in Trondheim, Norway. For many years she has worked with mathematics teachers in terms of professional development, and in different countries. One of her main research projects concerns teachers working with mathematics curriculum materials, including textbooks, in order to develop knowledge in/for teaching.webpage: http://hist.no/content/35372/Pepin-BirgitLuc Trouche is professor in mathematics didactics. He is director of research in the IFE (French Institute of Education), located in the ENSL (Ecole Normale Supérieure de Lyon). His research concerns the conceptualisation of mathematics in digital environments, and, more recently, with Ghislaine Gueudet, the professional development of mathematics teachers working on/with resources.Webpage: http://educmath.inrp.fr/Educmath/recherche/educmath/page_luc_trouche/

From the reviews:“This book is clearly intended for mathematics education researchers who investigate the preparation and teaching of K–12 mathematics teachers, it would also be of interest to mathematics teacher educators and curriculum designers. … The book is organized into four parts – each part has an introductory chapter and is followed by an ‘expert’s reaction.’ … a worthwhile read for those who are interested in how teachers use a variety of resources, material and non-material, digital and non-digital.” (Annie Selden, MAA Reviews, December, 2012)
