This reader explores the nature of interactions between children and their teachers. Part one looks at different cultural conceptions of the teacher-learner relationship, and how this relates to schooling, cognitive development and the acquisition of knowledge. Part two takes a closer look at the role of language and dialogue in interactions between adults and children in classrooms. Part three provides an overview of current research on collaborative learning. Part four looks at the potential impact of new technology on children's learning and cognition, and its role in creating global "learning communities."
