Benefiting from the advent of social software, information sharing becomes pervasive. Personalized rating systems have emerged to evaluate the quality of user-generated content in open environment and provide recommendation based on users' past experience. In this paper, a trust-based rating prediction approach for recommendation in Web 2.0 collaborative(More)
is deploying a flexible learning scheme for selected pilot courses in engineering education. In such a scheme, traditional lectures and written exercises are combined with additional Web-based learning resources. The main objective of this initiative is to sustain the evolution from traditional teaching to active learning and to better integrate the(More)
—This paper presents investigations on formal and informal requirements for personal learning environments taking into account students' personal and social learning practices. The potential of global Web 2.0 educational service bundles and informal learning communities, as well as their recommendation by educators are addressed. A scenario showing how(More)
Web-based experimentation is a key feature in the deployment of eLearning solutions for engineering education. At the Swiss Federal Institute of Technology in Lausanne (EPFL), Web-based experimentation is deployed thanks to a comprehensive environment called the Cockpit. This environment integrates all the components necessary to carry out hands-on practice(More)
This paper presents an innovative approach in flexible learning that can facilitate hands-on activities in engineering education. The approach focuses on the mediation role of artifacts within a learning community. The artifacts serve both as a medium and as a product of the collaboration process in the community. We have proposed the eJournal as a(More)
A new approach to developing Web-enabled environments for remote diagnostics, maintenance, and experimentation in engineering is based on a middleware layer that uses a Java-lntemet-Labview server to provide communication between Java programs and Labview virtual instruments. The authors illustrate their technique by applying it to the development of a(More)
A prototype system based on an inverted pendulum is used to study the Quality of Service and discuss requirements of remote-experimentation systems utilized for carrying out control engineering experiments over the Internet. This class of applications involves the transmission over the network of a variety of data types with their own peculiar Quality of(More)
—This paper investigates the acceptability of using social media for collaborative learning in the context of higher education. A social media platform, Graasp, is used to support students' learning activities in a project-based course. An evaluation of Graasp regarding its usefulness as a collaboration platform, a knowledge management site, and a gadget(More)
