Visual cognitive tools (VCTs) are external mental aids that maintain and display visual representations (VRs) of information (i.e., structures, objects, concepts, ideas, and problems). VCTs allow learners to operate upon the VRs to perform epistemic (i.e., reasoning and knowledge-based) activities. In VCTs, the mechanism by which learners operate…

This paper presents a cognitive model of how interactive multimedia authoring (IMA) affect novices' cognition in object-oriented programming. This model was generated through an empirical study of first year computer science students at the university level being engaged in interactive multimedia authoring of a role-playing game. Clinical…

Discussion of computer-supported collaborative learning, distributed artificial intelligence, and intelligent tutoring systems focuses on the concept of agents, and describes a virtual learning environment that has a multi-agent system. Describes a model of interactions in collaborative learning and discusses agents for Web-based virtual…

This article suggests that researchers need to reconfigure their conception of multimedia based interactivity. By integrating and extending earlier conceptions of the construct, it is argued that the cognitive processes of users should be central rather than peripheral to interactivity research. A model is presented in which interactivity is…

The ultimate aim of this research is to specify and implement a general authoring framework for content and knowledge engineering for Intelligent Educational Systems (IES). In this context we attempt to develop an authoring tool supporting this framework that is powerful in its functionality, generic in its support of instructional strategies and…

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…
