Architecture of Web-Based Intelligent Collaborative Learning : System Design and Peer Modeling

Article excerpt

This paper discusses architecture of web-based intelligent collaborative learning system (WebICL) and delves upon (systems design and peer modeling). A systems framework has been introduced, which has been designed based on the web-based collaborative learning fundamental theory. The peer modeling includes knowledge-based peer modeling, general peer model and virtual peer model in WebICL. The objective of this study is to implement an intelligent and flexible web-based intelligent collaborative learning system and to facilitate learners learning performance in web-based environment.

INTRODUCTION

Collaborative learning approach has dealt primarily with standard, classroom-based environment and not the web-based environment, which raised the question of how well the benefits of collaborative learning will translate to the web-based environment (Brandon, 1999). Collaborative learning means that knowledge is not something that is 'delivered' to students, but rather something that emerges from active dialogue among those who seek to understand and apply concepts and techniques. Student-student interaction in collaborative learning communities may contribute to the achievement of educational goals by influencing educational motivation and aspirations through peer relationships (Hiltz, 1993; Johnson, 1981). To collaborate means to work together, which implies a concept of shared goals, and an explicit intention of "add value"-to create something new or different through a deliberate and structured collaborative process, as opposed to simply exchanging information or passing on instructions (Kaye, 1994). Collaborative learning would be the acquisition by individuals of knowledge, skills, or attitudes occurring as a result of group interaction, or put more tersely, individual learning as a result of group process (Kaye A, 1992). Most outstanding experiments show that group learning is an important element of collaborative learning. Group learning is based on making individual fell responsible towards the group (Trentin, 1999). The idea that collaborative learning is the development of shared meaning among group members reflects the larger CSCL (computer supported collaborative learning) perspective on learning, a perspective that emphasizes the social creation of knowledge as the basis of learning. Meaning is not pre-packaged and delivered to the student for memorization; rather, it is negotiated among group members (Pea, 1994; Roschelle, 1992).

According to the above description, the main important components of collaborative learning in web-based environment is how to realize social context, group learning process, communication with each other (collaboration), and performance evaluation. Web-based collaborative learning is not only computer programming but also system integrated collaborative learning which depends process & social context. It should be more flexible and suitable for on-line group learning (Brandon, 1999). The collaborative development of requires a substantial amount of communication, perhaps even more so in on-line than in face-to-face groups. The intelligent learning method needs to be integrated into web based collaborative earning system because the intelligent characteristic is the basis of otherfeatures, suitable, practical, available.

RELATED WORKS

Web-based collaborative learning system can be divided into two categoriesone is asynchronous system and another is synchronous underwhich many practical systems were developed. The popular asynchronous system includes First Class, CSILE/Knowledge Forum, Learning Space, WebBoard, and WebCT; synchronous system includes Conference MOOS, WebChat Broadcasting System and Microsoft Netmeeting.

First Class is a very practical conferencing system accessible through a browser. Its features include 'software which has a rich environment that offers both real-time (synchronous) facilities and delayed time (asynchronous) resources. …
