A group-decision approach for evaluating educational web sites

With the advent of network technologies, many educational web sites have been developed to assist students in the learning of subjects on computer networks. However, without proper aid, students may have difficulty in selecting appropriate web sites, that are of benefit to them; hence, studying, evaluating and recommending educational web sites has become an important and challenging issue. In this paper, a group-decision approach is proposed for evaluating educational web sites. Several soft computing technologies have been employed in the approach, including fuzzy theory, grey system and group decision method. A computer-assisted web site evaluation system, EWSE (Educational Web Site Evaluator), has been developed, based on an experimental approach, which is capable of selecting the proper criteria for an individual web site and achieves greater accuracy when evaluating results. # 2003 Elsevier Ltd.
