A computer-based distance learning study aid on health economics (HELP
) for medical advisers was developed from an existing paper course usi
ng a user-centred, prototyping approach. We illustrate and discuss thi
s approach. The prototypes were iteratively tested and refined with po
tential users. The initial prototype was used for market research whic
h included a survey of medical and pharmaceutical advisers. Results fr
om the market research established the study aid's feasibility. The de
sign of the study aid was guided by the market research and by applica
tion of an architectural analysis and design framework. HELP was desig
ned in the form of an electronic, frame-based book with self-tests and
navigational facilities that permit additional exploration. On-line j
ournal articles were included for users' reference. The strategy adopt
ed for delivery of the new course consists of presenting the computer
study aid together with the paper course. The authoring shell that was
developed is generically reusable for other courses with other teachi
ng and learning strategies.
