The “discussion post” has been a staple in higher education online classrooms for decades. While educators of learning widely rely on asynchronous discussion posting to engage students using institutional management systems (LMS), requires mediation and motivation sustain participation, is considered task-oriented by students, frequently criticized inauthentic dialogue. Slides Strategy, which u...

This study aimed at investigating the potential of collaborative and e-collaborative writing modalities in developing interactional complexity, utilization of interactional demonstrators and density of interaction. To this end, 66 Iranian intermediate female English as foreign language learners (EFL) were selected to participate in this study according to their scores on Oxford Placement Test (...

The interactions among peers in Peer-to-Peer systems as a distributed collaborative system are based on asynchronous and unreliable communications. Trust is an essential and facilitating component in these interactions specially in such uncertain environments. Various attacks are possible due to large-scale nature and openness of these systems that affects the trust. Peers has not enough inform...

In this work we demonstrate the use of Petri Nets as applied to the interaction in a Collaborative Environment in the educational context, particularly Elearning. The scenarios and models proposed in this paper have been studied and applied to TeleMeios, an elearning platform in the Multimeios Research Laboratory of the School of Education, at the Federal University of Ceará. TeleMeios is a uni...

This paper elucidates the experience and thinking behind our new web-based environment for asynchronous group deliberation: Deme (pronounced "deem"). Deme grew out of participation in and observations of group decision making and community democracy, and is being developed within a university-community partnership to enhance civic participation and to bridge digital divides. Civic decisions in ...

There is a need for collaborative group activities that promote student social interaction in the classroom. Handheld computers interconnected by a wireless network allow people who work on a common task to interact face-to-face while maintaining the mediation afforded by a technology-based system. Wirelessly interconnected handhelds open up new opportunities for introducing collaboration and t...

Computer Supported Collaborative Learning methods support fruitful social interactions using technological mediation and orchestration. However, studies indicate that most existing CSCL methods have not been applied to large classes, means that they may not scale well or that it’s unclear to what extent or with which technological mechanisms scalability could be feasible. This paper introduces ...
