Collaboration principle in multimedia learning

Based on sociocultural and social cognitive theory, computer support for collaborative learning (CSCL) has emerged as a new research and development subdiscipline of computer-mediated communication. The emphasis of CSCL is on supporting collaborative learning activities in online multimedia environments. In this chapter, we review research on the nature of the technology used, how the learning groups are comprised (e.g., group size, learner characteristics), the learning outcome engaged by the task, the role of the tutor, the effects of community-building activities, the nature of the learning or communication assessment, and the effects of scaffolds or discussion constraints on learning. Based on this research, we make a variety of recommendations for the design and implementation of learning environments.
