This paper presents a framework for selling up a system to deliver on-line learning and leaching materials via the Internet, with enhanced rich-text, graphics, video on demand, interactive revision or self-test exercises, synchronous and asynchronous chat groups, and a quality monitoring mechanism. A prototype system has been set up at the Department of Building and Real Estate of the Hong Kong Polytechnic University and is being used in some of the undergraduate teaching. It is planned that a new MSc programme in Project Management will make full use of the system for the distance-learners.
