The Internet opens up the possibility of allowing students in different countries to tune in to the same information, thus creating a 'global lecture theatre', a symposium was told. Computer communications pioneer John December told the Hong Kong Web Symposium at the University of Hong Kong, that information put on the Internet could also boost links between educators. 'We have books. We have CD-ROM, which is efficient in storing information, but they are bound by locations and time. 'Teachers can only discuss and exchange ideas after receiving a copy. 'The Web brings to life communication, which allows people to relate information to each other.' He urged governments to set up national education webs, which would allow teachers to sort information more easily. 'The Web is a wonderful way to provide methodology for research on an international level,' he said. Besides spreading information, educators can make use of the Internet for teaching. 'Teachers can establish course webs to distribute on-line reference readings, syllabuses and suggest links to related on-line information. 'That can save students' time in searching books in libraries,' he said. Related modules on the Web could also be used to make tutorials more interesting. According to figures from the Australian Academic and Research Network, there are 10 million computers connected to networks in 170 of the world's 240 countries. Network manager George McLaughlin estimated that there were currently 10 million Internet users around the world. Head of the Department of Social Work and Social Administration at the university, Professor Law Chi-kwong, said: 'I am more alert to the use of the Web for social education. 'I have thought of using CD-ROM for creating an interactive learning package, but I think the Web is more up-to-date.' Professor Law said the Web could be used to distribute research papers in an economically and environmentally friendly way. 'Just mailing research papers costs us a few thousand dollars. 'I think we can save that money and spend it on making a Web site. That could allow more people to benefit and save much paper,' he said. Professor Hae Un-rii at the Department of Geography at Dongkuk University in South Korea, who visited the symposium to find out how to set up a network in her home country, said the Web would be useful to widen students' horizons. 'The Web is useful, especially for students who study geography. 'They can have updated knowledge of landscapes in the world,' she said. 'Many universities in Korea have computer centres. 'I think more and more university students will use the Internet two years from now.'
