Development And Application Of Computer-Assisted Instruction System

The continuous maturity and development of constructivism bring new chance and challenge for computer assisted instruction, develop the computer assisted instruction software under this theory which have more practicability and is propitious to students'self-construct is necessary. So, I try to develop the computer assisted instruction platform that based constructivism, and for better incarnates this platform's practical value, choose computer graphics as application example. Because, this curriculum has strong theoretical and involves many algorithms, it puzzles students with the massive algorithms in the learning process, makes them feel that it is difficult to understand .So apply this platform in the teaching of computer graphics, on the one hand, plan to change the actuality of computer graphics'teaching difficulty and on the other hand, can make this platform have more practical valueFor better research on this problem, this paper intend to research both on the classroom instruction and the extracurricular teaching, take the theory of constructivism as guiding ideology and the thought of integrableware as guiding method to build a computer assisted instruction platform that have the general use firstly. On the basis of particular analysis with the requirement of computer assisted instruction system, adopt the object-oriented methodologies of software engineering to do the omnibearing system design. And then use JAVA technology and one of integrated development environment-JBuilder2006 to realize the computer assisted instruction platform software both in client-side and server-side. Thereinto, the client-side mainly realize the creation, showing and retrieve of the cousreware, whereas the server-side mainly realize the management of the courseware and integrableware.On the basis of build the computer assisted instruction software that have general use, this paper take computer graphics as example, validate the function of this system both in classroom and extracurricular. Because the time is limited, when choosing the teaching content, aim at the character of rapid development of computer graphics, take computer figure generation as the clue to choose part of fundamental figure generation in classroom instruction and complex figure generation in extracurricular teaching.This article accomplishes all works that intend to do, but because the time is limited, the system also have many problems to be researched, for example we can try to publish this system on the internet to use by more people and also can let more people participate in the construction of integrableware library in future research.
