Over the past two decades, western scholars increasingly have embraced cultural-historical activity theory as a framework for thinking about knowing and learning in school and workplace settings. Yet in the adoption of this framework, many of its fundamental underpinnings in materialist dialectic have dis-appeared. Cultural-historical activity theory has been fitted to a fundamentally dualistic way of thinking the subject and object of activity, individual and collective, subjectivity and intersubjectivity, abstract and concrete, etc.

This book redresses the inappropriate translation by radically sticking to a materialist-dialectical theorizing of knowing, learning, participation, and identity. The authors draw on several detailed ethnographic studies at the kindergarten, elementary school, and middle school levels and in a workplace as case materials to articulate various aspects of the specifically human activity observed in each setting.
