Operating Systems IV is a subject taught to fourth-year information technology learners at Technikon Natal, a tertiary educational institution in KwaZulu Natal (South Africa). During 1998, the need to introduce elements of flexibility in this course was identified. As a result, a virtual classroom was used as a communal resource base and a construction site where learners collaborate. To date, two cycles of this project have been executed. The new Web-based approach to the course has led to substantial improvements in teaching practice. Furthermore, benefits have emerged well beyond the original aims of the project--the process that was set in motion at fourth-year level has begun to transform the broader curriculum. This paper reflects on the first two cycles of an action research project. It deals with the impact of the World Wide Web on a traditional curriculum. Changing teaching and learning methodologies are discussed. (Contains 16 references.) (Author/MES)
