A successful virtual educational environment must be able to emulate the kernel of traditional environment. That is, the interactions must be maintained to preserve the relationship between the teacher and learners in the on-line class, and the relationship among the off-line learners. We developed two systems to provide the needed functions which can provide on-line and off-line interactions. ...

in the present century, which is the age of rapid growth of technology and knowledge, in addition to the development of formal teaching, increasing attention has been paid to distant education by various organizations and societies. this paper is a report of a research entitled “a study of the success and obstacles of distant education services project of khorassan province literacy organizatio...

We consider an agent who has to repeatedly make choices in an uncertain and changing environment, who has full information of the past, who discounts future payoffs, but who has no prior. We provide a learning algorithm that performs almost as well as the best of a given finite number of experts or benchmark strategies and does so at any point in time, provided the agent is sufficiently patient...

Tele-training is a main issue nowadays and it is strongly motivated by the increased mobility of people. This mobility shouldn’t be a limit for a good training: pertinence and efficiency have to be the core of distant training environments. In this paper, we introduce SyTroN, a tele-learning system using virtual reality and tele-operation techniques. The first aim is to propose intuitive virtua...

— Collaborative learning models are widely used in educational institutions. These models require a high interaction level among students and are mainly oriented towards in-class scenarios. But when collaborative models are deployed in a distant scenario, user expressiveness is significantly reduced thus creating a gap that hinders the effectiveness of this collaboration. A computer-supported m...
