There were a total of 52 full papers, representing an acceptance rate of about 30%, plus one invited paper accepted for inclusion in this LNCS proceedings. The authors of these accepted papers came from many different countries. We would like to thank all the reviewers for spending their precious time reviewing the papers and for providing valuable com- ments that aided significantly in the paper selection process. Authors of the best papers presented in this conference will be invited to submit extended versions of their papers for possible publication in a special issue of IEEE Internet Computing. This was the second time that the ICWL conference was organized in China. It was particularly special this year to hold ICWL 2008 in China, as the Beijing 2008 Olympic Games were co-located in the same country during the conference period. We would like to especially thank our Organization Co-chair, Lanfang Miao, for spending an enormous amount of effort in coordinating the local arrangements. In fact, we would like to thank the entire conference Organizing Committee for their hard work in putting together the conference. In particular, we would like to express our appreciation to our Registration Chairs, Jiying (Jean) Wang and Lanfang Miao, and Treasurer Howard Leung for their tremendous efforts in communicating with the authors regarding registration matters and maintaining the registration lists up-to-date. Our Workshop Co-chairs, Elvis Leung and Philips Wang, organized a Workshop on Blended Learning (WBL 2008), which was co- located with ICWL 2008. At this workshop, participants could share their ideas on and experiences in supplementing e-learning with classroom learning. We would also like to thank Won Kim for delivering an invited speech and sharing his insightful views on Web-based learning research issues. Finally, we would like to thank all the authors of the submitted papers, whether accepted or not, for their contri- bution to the high quality of this conference. We will continue to count on your sup- port of the Web-based learning community in the future.
