Although collaborative learning is becoming a widely popular instructional method, little research has been undertaken considering human cognitive structures and their influence on the design of collaborative learning tasks. Using cognitive load theory as a theoretical framework in this study, forty-five undergraduate students were assigned to…

In this article, we discuss key requirements for collecting behavioural data concerning technology-supported collaborative learning activities. It is argued that the common practice of analysis of computer generated log files of user interactions with software tools is not enough for building a thorough view of the activity. Instead, more…

Web-based collaborative Problem-Based Learning (PBL) environments have great potential for learner improvement in solving ill-structured problems in practical situations. Web-based environments, however, offer learners relatively few chances to solve problems through face-to-face interactions compared to traditional classrooms, thereby making it…

The goal of this study was to gain insights into the interactions that occur in online communications in a project-based learning activity implemented in an undergraduate course. A multi-case study was conducted of six collaborative groups, focusing on the types and frequencies of interactions that occurred within each group and the perceptions…

Investigates the patterns of intertextual linking as learners engaged in problem solving when using hypermedia. Learners were observed in their synthesized discourse in six cases using Perseus, a Greek culture database. Discusses themes that emerged from learners' on-line protocols and interactions and implications for instructional designers.…

In this paper an analysis is made about how awareness in digital learning environments relates to communication, coordination and cooperation and, consequently, collaboration. A collaboration model, where awareness occupies a central position, is presented. The awareness elements of the AulaNet environment are also analyzed, seeking to identify…

Describes an interactive, cooperative-learning environment, "The Biology Sleuth." Characterizes students' interactions with this system, relates the underlying design concepts and principles, and presents a rationale for the system design. Describes a series of three formative evaluations, that were critical in the maturation of the system.…
