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...

It has become popular in recent years to talk about identity as an aspect of engagement with technology in virtual environments, in games, in social media, and in our increasingly digital world. But what do we mean by identity, and how do our theories and assumptions about identity affect the kinds of questions we ask about its relationship to technology and learning? Constructing the Self in a Digital World takes up this question explicitly, bringing together authors working from different models of identity but all examining the role of technology in the learning and lives of children and...

How Students Come to Be, Know, and Do builds a theoretical argument for and a methodological approach to studying learning in a holistic way. The authors provide examples of urban fourth graders from diverse cultural and linguistic backgrounds studying science as a way to illustrate how this model contributes to a more complete and complex understanding of learning in...

Co-Operative Action proposes a new framework for the study of how human beings create action and shared knowledge in concert with others by re-using transformation resources inherited from earlier actors: we inhabit each other's actions. Goodwin uses videotape to examine in detail the speech and embodied actions of children arguing and playing hopscotch, interactions in the home of a man with severe aphasia, the fieldwork of archaeologists and geologists, chemists and oceanographers, and legal argument in the Rodney King trial. Through ethnographically rich, rigorous qualitative analysis of...
