The significance of socially shared metacognitive regulation (SSMR) in collaborative learning is gaining momentum. To date, however, there is still a paucity of research of how SSMR is manifested in asynchronous computer-supported collaborative learning (CSCL), and hardly any systematic investigation of SSMR’s functions and evolution across different phases of complex collaborative learning act...

Email is the most common collaborative tool in use today. Although originally designed as an asynchronous communication tool, it is being used increasingly for information management, coordination and collaboration tasks. For effective collaborative work, email must be designed that meets users’ needs and their experience. The traditional approach to designing interfaces has been increasingly c...

One of the main problems of collaborative filtering recommenders is the sparsity of the ratings in the users-items matrix, and its negative effect on the prediction accuracy. This paper addresses this issue applying cross-domain mediation of collaborative user models, i.e., importing and aggregating vectors of users' ratings stored by collaborative systems operating in different application dom...

Online learning is the latest in a long list of social technologies that have been introduced to improve distance learning by adding various augmentations, substitutions, or blending of new pedagogical approaches and technologies. Technologies utilized for distance and online learning include: correspondence courses, physical mail, and printed matter; telephone and/or audio recordings; televisi...

This paper introduces intersubjectivity as a concept playing a crucial role in collaborative tasks, even when performed between partners at a distance. Two 5th grade classes from two European countries (Italy and Greece), collaborated in writing fairytales inspired by philosophically relevant issues. The software supporting the task is an asynchronous virtual environment. Videos recorded in the...

The ability to collaboratively edit work artefacts is important in many kinds of editing tools, including Computer-Aided Design (CAD) tools, Computer-Aided Software Engineering (CASE) tools, drawing packages, and document editors. However, most existing such tools either do not support collaborative editing or provide limited collaborative editing facilities. We describe our recent work in addi...

Computer-supported collaborative learning (CSCL) is an emerging branch of the learning sciences concerned with studying how people can learn together with the help of computers. As we will see in this essay, such a simple statement conceals considerable complexity. The interplay of learning with technology turns out to be quite intricate. The inclusion of collaboration, computer mediation and d...

A variety of field trials have been conducted at NJIT in the past few years to demonstrate the utility of a Delphilike approach to promoting asynchronous class wide collaboration. These utilized the Social Decision Support System (SDSS) originally developed as a Computer Mediated Communication (CMC) system for large group decision support. This paper provides an overview of these studies and th...

Although most online learning environments are predominately text based, researchers have argued that representational support for the conceptual structure of a problem would address problems of coherence and convergence that have been shown to be associated with threaded discussions and more effectively support collaborative knowledge construction. The study described in this paper sets out to...

Through a series of projects carried out by the Computer–Human Interaction and COllaboration (CHICO) group University Castilla-La Mancha, some proposals are presented to improve current e-Learning systems making use different paradigms human-computer interaction. Synchronous asynchronous collaborative systems, ubiquitous computing, augmented reality can learning environments. The artificial int...
