The construction of a very fast network backbone between all Scottish universities, in conjunction with the formation of a common core curriculum for Scottish medical schools teaching child health, has provided the schools with an opportunity to provide collaborative, computer assisted learning (CAL) across the World Wide Web, delivered by a central site. CAL, embracing the latest technologies of Java, Dynamic HTML, Javascript and MPEG-1, was successfully developed and implemented in the form of interactive, multimedia Model Patients. This paper discusses: materials and methods used, including the World Wide Web, Java, and Dynamic HTML; student user experiences to date; and implementation issues, including hardware and software requirements, delivery speed, and design. It is concluded that use of the Web as a delivery medium for CAL is both feasible and practical with the provision of high bandwidth networking; collaboration between institutions allows for resources to be shared from one server, leading to efficient use of developers and content contributors and lowering delivery costs and administration needs.
