计算机辅助教学系统的开发与应用 计算机辅助教学系统的开发与应用 Development and Application of Computer-Assisted Instruction System【中文摘要】 建构主义理论的不断成熟与发展为计算机辅助教学带来了新的契机与挑战,在该理论的指导下开发更具实用性、更有利于学生自我建构的计算机辅助教学系统是非常必要的。因此本文尝试开发基于建构主义的计算机辅助教学软件平台,且为了更好的体现该软件的应用价值,选取计算机图形学作为该软件的应用举例。该课程理论性强,涉及算法多,不少学生在学习过程中被困扰,感到难于理解。因此将该软件应用到计算机图形学的教学中,一方面拟改善该课程教学难的现状,另一方面也使之更具实用价值。为了更好的研究该问题,本文在研究过程中从课堂教学与课外教学同时入手,以建构主义理论为指导思想,以积件理论为指导方法,首次搭建了具有通用性的计算机辅助教学软件平台。在详细分析计算机辅助教学系统功能需求的基础上,采用面向对象的软件工程方法进行了全方位的系统设计,然后利用JAVA技术和JBuilder2006集成开发环境,分前台客户端和后台服务器端两部分实现了计算机辅助教学平台软件系统。其中前台客户端主要实现课件新建、放映、检索等功能,而后台服务器端主要实现对课件、积件库的管理工作。在搭建通用计算机辅助教学软件的基础上,以计算机图形学为例,分课堂和课外两部分对系统功能进行了验证。受时间限制,在教学内容的取材上,针对计算机图形学发展迅速的特点,以计算机图形生成为线索选取了课堂教学的部分基本图形的生成和课外教学的复杂图形的生成。本文完成了预期的所有工作,但由于时间有限,系统还有许多问题有待于进一步研究,例如在今后的研究中可以尝试将系统发布在网络上,供更多人使用,也可以让更多人参与到积件库的建设中来。【英文摘要】 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 studentsself-construct is necessary. So, I try to develop the computer assisted instruction platform that based constructivism, and for better incarnates this platforms 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 graphicsteaching 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 le more people participate in the construction of integrableware library in future research.【中文关键词】 计算机辅助教学; 计算机图形学; 建构主义; 积件 【英文关键词】 Computer-Assisted Instruction; Computer Graphics; Constructivism; Integrableware 【毕业论文目录】中文摘要 4-5 ABSTRACT 5-6 文献综述 7-12 1. 绪论 12-14 1.1 研究背景 12 1.2 问题的提出和意义 12-13 1.3 主要工作内容 13-14 2. 计算机辅助教学系统的理论基础 14-17 2.1 建构主义理论 14-15 2.2 积件思想 15-16 2.3 面向对象的思想 16-17 2.4 本章小结 17 3. 计算机辅助教学平台的需求分析与总体设计 17-23 3.1 平台的总体需求 17-20 3.2 平台数据库的设计与实现 20-23 3.3 系统的特点 23 3.4 本章小结 23 4. 计算机辅助教学平台的详细设计与实现 23-50 4.1 平台的设计思路 23-25 4.2 平台的设计与实现 25-50 4.3 本章小结 50 5. 图形生成模型的设计与实现 50-66 5.1 基本图形生成模块的设计与实现 51-56 5.2 分形图形生成模型的设计与实现 56-60 5.3 元胞自动机图形生成模型的设计与实现 60-66 5.4 本章小结 66 6. 总结与展望 66-69 6.1 总结 66-67 6.2 展望 67-69 参考文献 69-71 致谢 71-72 附录 72-73
