Distance learning combines modern computer and communication technologies to provide an interactive environment between students and far-away teachers. Through multi-media video conferencing systems and ISDN network, teachers and students can perform face-to-face communication from different places, and the design of teaching material can also be multiform. National Hsin-Chu Teachers College started its experimental distance-learning project since 1996, based on the platform of campus network and PC-based video conferencing systems. After funded by the Ministry of Education (MOE), we purchased a larger video conferencing system, a multi-port control unit (MCU), and other related instruments to set up the distance-learning classroom and courses as well. Since then, our college became a member of many schools executing MOE's distance-learning projects. Teaching and taking distance-learning courses are both new experiences for teachers and students. Teachers must perform their instruction which is broadcast to far-away receiving classroom through ISDN network. They can also communicate with students after class by using E-mail or Bulletin Board System (BBS). Students can prepare their homework in the form of homepages, which are linked to the WWW server designated by their teacher. As a result, the students can acquire course knowledge and also become acquainted with the usage of Internet tools and resources. However, distance learning has its drawback as compared with traditional learning system. For example, low visual resolution and interactivity may reduce the learning effectiveness directly, and taking exam or submitting homework is more laborious. Also, course schedule and registration requires corporation between broadcasting and receiving schools. These problems can only be solved after the enhancement of technology and establishment of execution model in distance learning systems.
