| Summary: | 碩士 === 國立臺灣師範大學 === 工業教育研究所 === 86 === In accordance with the development of National Information Infrastructure project of " Distance Learning pilot system " is set up with 3 expenirimental Distance Learning subsystems including " Real time broadcasting "," Virtual Classroom " and " Course-on-demand ". National Taiwan University, National Tsinghua University, National Chiao Tung Univ., National Cheng Kang Univ. and National Chung-Chen Univ. can choose one of the experimental sets of system to install and test on the basis of each school''s characteristics and experiences. Therefore, on-line teaching by means of Internet has become an important research task.
Because of the limit of geographical distance and time, teachers and students cannot have class at a proper time and place, which results in insufficiency of learning. VC is a kind of teaching activity that combines information and Internet technology to be applied in Distance Learning. It mainly employs the communicative function of Internet and the structure of Electronic Information Exchange System, to construct Virtual teaching and learning circumstances to make up the demerit of being limited by time and space, which is typical to traditional teaching methods. Besides, to create a good learning environment to enhance learning effect is the goal of all educators. Traditional teaching method is that teachers pass knowledge of teaching materials down to students in one-way direction. Such way is limited by distance, time and space. Also, it has the problem of difficulty in controlling pace of teaching and in evaluating learning effect. Thus, if we want to solve the problem generated by traditional technique and create a good learning environment, we have to improve such 4 factors as teacher, teaching material, classroom, and student.
In coordination with Executive Yuan''s "Plan of Development and Training of Information software Professionals," schools and private institutes will cooperate to promote the development and training of software professionals. The goal is to develop and train 5000 people in the year of 1999, 7500 people in 2000 and 10000 in 2001. At present every trade and information business face the serious shortage of software professionals. Besides those software professionals who are cultivated by standard education system, it''s estimated that there is a lack of 5000~10000 people per year. With a View to this phenomenon, this study tries to establish and install Visual Basic Virtual Classroom to cultivate information software professionals. Any students at a far end who are interested in learning Visual Basic can practice on-line learning through internet at any time. Systematic analysis and programmed record of learner''s learning path will provide basis for diagnosis of student''s learning. At last, the conclusion of the study is as follows : VC has 5 characteristics.
1. Providing Service
The aim of VC is to serve users learning Visual Basic with necessary contents and techniques for using Visual Basic.
2. Open to the public
Any interested students or teachers, following a fixed norm can enter the system for learning and teaching.
3. Establishing by collaboration
The designers of the system analyze and plan the control factors of courses and contents in advance, and adopt some established and preserved contents of other Web-sites. This Web-site is often updated to keep it new and plentiful. For example, the basic common sense of Visual Basic, useful commands, and differences of all versions are set up in this site. The programming of high-tech programs are linked from other professional Web-sites to this site by means of hyperlink.
4. Using Multimedia
Using the most advanced interactive technique of establishing Web-site such as ASP of Platform, etc. and database server to achieve the effect of interactive browsing effect. The record of student''s learning history by computer also realizes the idea of internet-centered learning.
5. Capacity of expansion
The system not only adopts the protocol of Internet/intranet like TCP/IP, HTTP/HTML, SMTP and soon; but also classifies units and characteristics of service items to make the Web-site liable to expansion.
