Learning by doing: collaborative conceptual modelling as a path forward in ecosystem-based management

Distance Learning as "Learning by Doing"

The papers in this Special Issue of Educational Technology and Society are extensions of presentations given at the 1999 Texas Distance Learning Association (TxDLA) Annual Conference held April 5-8, 1999, in Waco, Texas, U.S.A. TxDLA is pleased that our collaboration with IFETS has afforded the opportunity to present these papers for publication in their official Journal. The eight extended pap...

Introduction to Collaborative Conceptual Modelling

Collaborative E-learning Processes in Conceptual Content Management Systems

An ongoing trend of e-learning systems is to not only concentrate on the management of learning materials and other information, but instead to focus on learning processes. Thus a stronger focus is put on the people engaged in learning activities: the learners which shall be served by an e-learning system and the teachers who instruct and guide the learners. The Conceptual Content Management (C...

DisTriB: Distributed Trust Management Model Based on Gossip Learning and Bayesian Networks in Collaborative Computing Systems

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...
