The Open University of Hong Kong aims to implement full- scale Web-based instruction in two years' time. The university's newly-appointed Director of Technology Development Professor, Leung Chun-ming, said using technology to enhance distance learning was at the top of his agenda. With Web-based instruction, teaching activities would be conducted on the World Wide Web, which integrates text, sound and images. Students would be able to plan their studies at their own pace and convenience through their personal computers. To implement the plan, the university will first convert materials for more than 100 existing courses into on-line versions. Tutors and students will then be able to interact on the Web. There will also be training sessions for students, tutors and academics to introduce them to Web-based instruction. Professor Leung said Web- based instruction had four key components: multimedia course materials; on-line drills and tests; monitoring and assessing students' performance; and communication between teachers and students.
