Opis

Drawing upon field studies conducted in 1978, 1980, and 2001 with the Oksapmin, a remote Papua New Guinea group, Geoffrey B. Saxe traces the emergence of new forms of numerical representations and ideas in the social history of the community. In traditional life, the Oksapmin used a counting system that makes use of twenty-seven parts of the body; there is no evidence that the group used arithmetic in prehistory. As practices of economic exchange and schooling have shifted, children and adults unwittingly reproduced and altered the system in order to solve new kinds of numerical and arithmetical problems, a process that has led to new forms of collective representations in the community. While Dr. Saxe s focus is on the Oksapmin, the insights and general framework he provides are useful for understanding shifting representational forms and emerging cognitive functions in any human community. Video and visual supports for the book, the Cultural Development of Mathematical Ideas: Papua New Guinea Studies, which are key to a deeper understanding of this ground-breaking project are available online at http: //www.culturecognition.com"

Recenzje

'I can see at least three reasons why this book is a must-read for every mathematics education researcher. First, as an inexhaustible source of insights about numerical thinking and its development and also about human thinking in general, it can be trusted to provide the interested reader with a hearty serving of food for thought. Second, it is not every day that one sees a longitudinal study capturing a historical change in the making. This turns Saxe's story into something truly unique and precious. Finally, these [pages] of well-written text are too enjoyable a read to be missed.' Anna Sfard, Educational Studies in Mathematics
