Development Of CAI System Based On CSCL

With the development of globalization and advancement of information technology, represented by multimedia computer and internet, revolutionary changes have been brought to education. In traditional field of education, classic teaching is characterized by the teacher-focused mode in which the teacher plays the main role of an orator, and the students serve only as listeners, Another choice is the teaching by correspondence or through broadcasting and television, however, even this kind of distance teaching fails to provide opportunity for the str nts to give full play to their initiative, activity and creativity. This is still a kind of closed teaching especially when the students in the same classroom in different levels and are differently based. The teacher will find it difficult to decide what and how to teach a class of verified levels. However, modern distance education based on internet, which combine internet with CAI (computer aided instruction), is born to meet the challenge, though it is still in its initial stage of experiment as how to give full play to its throng points.This paper presents a new building of CAI system which is computer support corporative learning (CSCL). Based on (CSCW), and instructed by "CAI system of information technology", this new building of CAI system, which is CSCL successfully combined multimedia technology, OLE, ASP.NET, and ADO.NET, it offers the users two choices of stand-alone edition and Network Edition which the users can choose freely according to their own hardware setting. The highlight of stand-alone edition design lies both in the realization of physical evaluating function of operation exercises, and the animating demonstration function of the operation. With this highlight, the new building of CAI serves as a patient "teacher" to meet the need of every individual student, who allows the students to decide by their own when and where to study or to communicate with the "teacher", At the same time, teachers are also released from the heavy task of homework correction. On the basis of stand-alone edition, the design of Network Edition adds more, including Co-room, BBS, information Board, and opinion Box where you can share room forcommunication and discussion between students VS teachers, and students VS students, or teachers VS teachers.This paper is a detail description of the theoretical Basis, the design thought, and the detail process of its enforcement. The first two chapters give a brief introduction of the CAI, the development of distant education, national and international developments, general outline of the system, the designing environments and its theoretical basis. The following four chapters give detail introduction of the system project, technological adoption of the system and its function and enforcement. The last chapter gives a total generalization of the system project, and points out its incompleteness and its improvements.This system of CSCL is very practical and has been carried out in our school as a test. The stand-alone edition of the system is convenient for market sale and commercial spread, while the Network Edition can serve as a training mode of schools and enterprises.
