Abstract:Computer-Supported Collaborative Learning (CSCL) is the field concerned with how Information and Communication Technology (ICT) might support learning in groups (co-located and distributed). The chapter surveys key studies, common technologies, and significant events in the field. It presents basic concepts, multiple perspectives, and emerging trends in CSCL. A main distinction is drawn between the systemic and the dialogical approach to research. The former is rooted in the cognitive perspective on learning and the latter the sociocultural perspective on learning and development. Design-based research is prominent in the field and we differentiate pedagogical and technology design as two means to scaffold research, collaboration and learning.
