Much of the most important learning happens through social interaction. Learning, Culture and Social Interaction is an international journal devoted to the publication of high-quality research on learning within, and through, social practices. Its particular focus is on understanding how learning and development are embedded in social and cultural activities, and how individuals and collective practices are transformed through learning. Such understanding requires a careful analysis of learning in social context, and of the communicative processes involved. In-depth studies of interaction in schools (in various subjects and settings), universities, work-places, voluntary organizations, public agencies, hospitals, laboratories and other institutional settings will be welcome, as well as studies of informal settings such as everyday conversations, play settings, youth clubs, games and other cultural practices. Longitudinal studies of learning trajectories are relevant as are analyses of contexts and interactional patterns that hinder learning.
