Relevance Feedback and Content Aged in Course Management System

Abstract

User’s Reference Feedback and trust information is needed for both learners and teachers in virtual university system. In this paper, we presented an advanced Petri Net model to manage the workflow of a web-based multiple participants in virtual University. The presented approach not only can conspicuously help the developer to comprehend the interaction relationship but also to easily construct a shared and trusted virtual world. This approach was based on the scaffolding theory. Learning activities of students and teachers are supervised and understood by each others by the intelligent control system. Their behaviors including the student’s self regulations and the teacher’s/virtual campus regulations are performed and built with trust development. Problems of providing the multi-user interaction on the Web and the solutions proposed by the Petri Net model are fully elaborated here. This paper can be used as a basic/fundamental research framework and tools to study and understand the characteristics of e-learning and to explore its optimal education application.
