Welcome to the 4th International Conference on Hybrid Learning (ICHL 2011). After spending ICHL 2010 at the Beijing Normal University and ICHL 2009 at University of Macau, we are back to Hong Kong with our new host, The University of Hong Kong’s School of Professional and Continuing Education (HKU SPACE).

“Hybrid learning” is undoubtedly the new frontier in education as neither virtual nor physical resources alone can provide the best teaching and learning environment. Technology is finally advanced enough that information or learning materials can be accessed immediately anywhere and anytime. Hybrid learning provides a great way forward for educators who are interested in helping students to learn without blindly using of technology for technology’s sake. We could ultimately create learning experiences to compensate for the shortcomings of, or at least to complement, conventional face-to-face teaching. We are thrilled that it has become mainstream and many models with educational underpinnings have emerged.

Many parties made ICHL 2011 a success. We would like to take this opportunity to thank: (a) the Organizing Committee; (b) the Program Committee; (c) the organizers; (d) all participants; (e) sponsors; and (f) all supporters.
