1. The Remote Blackboard Presenter System for Remote Lessons in Conventional Blackboard Based Style
Kenzi WATANABE <watanabe@is.saga-u.ac.jp>


The instruction based learning is typical style of lessons in school. In the instruction based learning, teachers use a blackboard as a teaching material. We call this style of lessons as "Blackboard Based Lessons".

We are researching next generation distance learning with rich-media environment. We have developed a remote blackboard presenter system. In the distance blackboard based lessons using the DVTS, a screen in the students' side shows blackboard at the teacher side by the DVTS. When the teacher pushes "capture" button of the system, the system captures the video stream, and creates high quality screen-shot image file. The system transfers the image file to the students' side automatically, and the system presents the image to the sub screen in the students' side automatically.

In this paper, we described details of the system.

2. Presentation: Vclass - Presentation Component
Chaiwarat Chaiyapotpanit <chaiwarat@ait.ac.th>


This paper describes the presentation component of a Web-based Learning Management System called Vclass. The presentation component utilizes both static information (i.e., electronic documents and images) and dynamic information (i.e., audio/video streams) along with interactive information to enhance typical learning contents presentation. Learning objects, comprising of static and dynamic information, are stored on a multimedia database and can be retrieved on-demand via Web browsers. User interface is divided into three sections displaying static, dynamic and interactive information, respectively. Viewers can control the audio/video presentation through a set of VCR-like functions where corresponding static information is synchronously displayed using the developed Java applet controller and a dynamic pointer mechanism. An electronic notepad as well as interactive information in the forms of chat, discussion board and email help provide a close to "real-life" classroom environment.


Mr. Chaiwarat Chaiyapotpanit has been working as a project manager of Distance Education Center (DEC) at Asian Institute of Technology (AIT) since 2002. His major tasks are to lead the DEC team to research and to develop a Learning Management System (LMS) called VClass.

1. A framework for facilitating video-centered discussions on the Web
Ng S.T. Chong <chong@unu.edu>


One form of adding interactivity to online learning is video annotation, which is an active field of research in content-based video retrieval and summarization. However, it is less known in educational contexts, partly due to the lack of video annotation capabilities in current learning tools and systems. With the popularity of Web video lectures, there is a rising demand for the support of discussion and collaboration around video contents. This work presents the design and preliminary evaluation results of a Web-based multi-user video annotation environment. The system allows users to attach notes to video segments and share their notes with other users asynchronously. Unlike the traditional use of video annotation, which is mainly designed as a single-user desktop application, the Web-based implementation allows users to learn and collaborate with fewer constraints of time and location. At the same time, it can be readily integrated in a Web learning environment.


Ng S. T. Chong. He directs the research at the Media and Technology Laboratory of the United Nations University and heads the advancement of the computing environment of the university. He is currently involved in the development of systems and tools to facilitate and increase opportunities for people to collaborate on the Web. He completed his MS degree in Computer Science from the University of New Mexico in 1992 and passed his PhD comprehensive examinations in 1995.

2. Grid Architecture for eLearning
Eric YEN <eric@gate.sinica.edu.tw>


eLearning usually means how to take advantage of virtual learning environment for more dynamic, effective, and on-demand ways of activities, fulfilled by the deployment of knowledge technologies, and to be facilitated by cooperative learning. Abundant and assorted learning materials could come from anywhere in the world thru Internet, and also users are dispersed all over the world. In addition, there is always needed to harvest, integrate and even mining useful information from heterogeneous resources. Besides the aspect of learning and cognition theory, information infrastructure becomes the most critical point for eLearning. Grid infrastructure deconstructs computing resources into fabric scale but makes the Internet as a super computer system, and paves the way of optimization of usage of distributed resources. Even though not a single total-solution application system has been produced, various individual customized applications (such as EU DataGrid, PPDG, SRB, etc.) and common standards building (for instance, GSI, DGSA, and Grid FTP) have laid the foundation for the future development of Grid. However, Grid is the most viable solution for all sorts of group works among Internet-based virtual organizations right now. In Academia Sinica, a prototype of eLearning environment over Grid is under construction. Major requirements come from collection of use cases of target groups. A common application layer will be built upon the Grid middle serves as a dedicated application interface to the underlying infrastructure. Lessons and experiences learned and future plans will be discussion in this presentation.


Eric Yen is now in charge of the Computer System Management Team and GIScience Team in the Computing Centre, Academia Sinica. He has been leading a project for archiving historical maps and remote sensing imageries of modern China, and also acts as a project leader for building a WebGIS-based spatiotemporal application environment and related technical support in the National Digital Archive Project in Taiwan since 2001. In addition, He is helping coordinating the development and deployment of Grid Technology for basic research in the Academia Sinica.

3. Development of Multipoint Communication Systems for Remote Seminar
Toshihiro Hayashi <hayashi@is.saga-u.ac.jp>


This paper describes communication systems for constructing a multi-point remote seminar environment. The remote seminar is a remote education type that consists of only a few members connected by an information network. We propose a system construction model called "MASF: Multi-Applications with Single Function" that establishes the guidelines for developing communication systems for remote seminars. In the MASF model, each system has one or only a small number of communication function(s). Seminar members can participate in the seminar by using plural MASF based systems. Based on the MASF model, we developed four prototype systems for Linux and Windows. These systems provide multi-point and peer-to-peer communication. In our systems, we encountered two problems: (1) the number of data connections is increased, and (2) it is difficult for members who are unfamiliar with the MASF style to use these systems adequately. In this paper, we propose a data-flow control system called "MHB: Media Handling Block" to deal with problem (1), and an auto configuration system called "ACU: Auto Configuration Unit" to deal with problem (2).

3. Distance Education in China: Modes, Policy, Market and Future Development
Feiyu Kang <fykang@mail.tsinghua.edu.cn>


Distance education was started in China in 1950s. People received textbooks and other course materials from post office, and learned by themselves, then had class tutorials in some centers by face to face, finally passed the uniform examinations. In 1980s, Central University of Television and Radio was established and developed very quickly, by far, it has 1 million students in China. Today, modern distance learning has become very popular in China since 1997, there are more than 1.5 million students took the courses from 67 top universities permitted by the Ministry of Education. Their motivations are to catch a diploma, bachelor and master degrees. Both part time and full time students are learning by using computer, website, cable TV as well as CD-Rom, VCD, DVD, paper materials. The data transportation modes include internet, satellite, ISDN as well as mailings. Tutorial and discussions may be conducted by emails, telephones, internet, satellite, ISDN conferences. China has large area and lack of high education resource, the enrollment percentage for high education in China is only 13% currently, and therefore, distance education has a huge market in China.

Tsinghua University is the earliest and largest university for distance education. It offers 4 programs at undergraduate level and 5 programs at postgraduate level as well as many programs for professional training. Tsinghua adopts hybrid system including internet, satellite and cable TV, the tutorials are given by ISDN, internet and satellite. There are more than 20 thousand students who are learning in more than 100 learning centers in the whole country.

I'm a professor now in the Department of Materials Science and Engineering, and the executive deputy dean, in the School of Continuing Education, Tsinghua University.

4. Metadata for eLearning Objects
Arthur Chen <arthur@gate.sinica.edu.tw> and Sophy Chen <sophy@gate.sinica.edu.tw>


Nowadays, many electronic information resources are used to support electronic learning (e-Learning) on Internet scale. How to organize these electronic resources systematically in order to facilitate discovery, management, exchange, and evaluation on e-Learning resources becomes an urgent but essential issue for e-Learning community. Metadata is one of approaches to achieve these goals. In terms of metadata domain, e-Learning resources covers a variety of dimensions, that is, course materials, learning activities, learning platform, and persons including tutor and learner. This paper aims to offer a practical metadata approach and related findings on e-Learning metadata in Taiwan. Firstly, the paper reviews on current existing metadata standards and research projects, like DCMI-Education, LOM, SCORM, GEM, and so forth. Secondly, a case study approach is adopted to examine the state-of-the-art e-Learning cases. One is National Science Digital Library in USA, and the other is the Edu.Cities in Taiwan. Thirdly, a comparison between NSDL and Edu.Cities is also conducted. Finally, several strategic advice and related issues on e-Learning metadata in Taiwan will be addressed.
