This book presents a broad range of research related to how social knowledge is shared, transmitted and transformed in the context of education and professional formation. The chapters of this edited collection reflect different theoretical and empirical approaches to that form of common-sense knowledge called social representations, the theory of which was developed almost a half-century ago by Serge Moscovici. Scholars from various research institutions in Brazil, France and Sweden, spanning a wide variety of disciplines within the social sciences, have contributed chapters that are grouped into three main categories related to education, professionalization and transformation of knowledge. Part I covers theoretical approaches to understanding the transformation of social knowledge from the perspective of social representations. Part II analyzes the impact of the theory of social representations on the transformation of knowledge in the field of education and professional formation. Finally, Part III presents several empirical studies focused on the social and cultural frames that condition the transformation of knowledge. While the book is devoted to education and the emerging field of research on professionalization, it will also appeal to anyone with a general interest in how people acquire their worldviews and how these views influence their actions.
