nd The 2 International Conference on Web-Based Learning (ICWL 2003) took place in Melbourne, Australia. ICWL 2003 followed the tradition of the successful ICWL 2002 held in Hong Kong and aimed at providing an in-depth study of the technical and pedago- cal issues, as well as incorporating management issues of Web-based learning. Additionally, there was a focus on issues of interest to the learner, o?ering the optimal Web based learning environment to achieve high academic results. - akin University organized this conference in conjunction with the Hong Kong WebSociety,toprovideaforumwhichgatherededucators,researchers,techno- gists and implementers of Web-based learning from around the world to discuss, collaborate and advance all relevant issues pertaining to this area of research. The main focus of ICWL 2003 was on the most critical areas of Web-based learning, in particular, Web-based learning environments, virtual universities, pedagogical issues related to Web-based learning, multimedia-based e-learning, interactive e-learning systems, intelligence in on-line education, e-learning so- tions, CSCL, and authoring tools for e-learning. In total, the conference received 118 papers from researchers and practitioners from 13 countries. Each paper was reviewed by at least three internationally renowned referees. Papers were ri- rously examined and selected based on their originality, signi?cance, correctness, relevance, and clarity of presentation. Among the high-quality submissions, 50 papers were accepted and included in the proceedings. Later, the proceedings editors will recommend that some high-quality papers from the conference be published in a special issue of an international journal.

With the rapid development of Web-based learning and new concepts like virtual cla- rooms, virtual laboratories and virtual universities, many issues need to be addressed. On the technical side, there is a need for effective technology for deployment of W- based education.On the learning side, the cyber mode of learning is very different from classroom-based learning. How can instructional developmentcope with this new style of learning? On the management side, the establishment of the cyber university - poses very different requirements for the set-up. Does industry-university partnership provide a solution to addressing the technological and management issues? Why do we need to standardize e-learning and what can we do already? As with many other new developments, more research is needed to establish the concepts and best practice for Web-based learning. ICWL 2004, the 3rd International Conference on Web-Based Learning, was held at the Tsinghua University (Beijing, China) from August 8th to 11th, 2004, as a continued attempt to address many of the above-mentioned issues. Following the great successes of ICWL 2002 (Hong Kong) and ICWL 2003 (Australia), ICWL 2004 aimed at p- senting new progress in the technical, pedagogical, as well as management issues of Web-based learning. The conference featured a comprehensive program, including a tutorial session, a keynote talk, a main track for regular paper presentations, and an - dustrial track. We received 120 papers and accepted only 58 of them in the main track for both oral and poster presentations.
