电子技术网络课程的研究与实现
|
摘要
随着网络技术和现代教育技术的发展,网络课程已经成为远程教学资源的重要组成部分和开展网络教学的基本单元。高质量网络课程的研发成为网络教学资源建设和教育教学改革重大而紧迫的课题,引起广大教育工作者的极大关注。
本文在研究和分析国内外网络课程发展现状的基础上,结合机械类专业电子技术课程教学改革实践,探讨了该网络课程的教学设计原则、方法、步骤和技术实现:提出了由8个模块组成的电子技术网络课程体系构架。以建构主义学习理论为主导、其他教学与学习理论为补充,充分运用计算机技术,实现了基于B/S结构的电子技术网络课程平台和框架;完成了电子技术网络课程各个模块的设计。
本文对电子技术网络课程的课程内容、教学资源和讨论天地等部分的设计进行详细论述,建立了丰富的电子技术课程动画资源库、图片资源库和网络资源链接等相关资源,这些教学资源不仅适用于网络教学,也可作为传统的课常教学素材和辅助教学手段。
在深入研究的基础上,本文提出了采用数字水印技术对电子技术网络课程中的静态图像和Flash动画进行加密处理的方法,比较有效地解决了电子技术网络课程知识产权保护的问题。
本文从6个方面介绍了论文的主要工作及特点,对其他网络课程的研究与开发也具有一定的参考和借鉴作用。最后,为进一步改进和完善电子技术网络课程,还对电子技术网络课程的后续开发从3个方面进行了阐述。
本文研究属于西北工业大学重点规划教材资助项目(MO15151)。
With the development of network and modern instructional technology, web-based course has been an important part of distance instruction resources and a basic unit of web-based instruction. To develop high-quality web-based course becomes an important task of constructing web-based instruction resources and teaching reformation, it brings the greatest attention of the most teaching staff.Based on the studying and analyzing on the status and development of web-based course home and abroad, the paper combines the teaching reformation of enginery electronic technology course, probes into some aspects of web-based course that include foundational principles of teaching design, design steps and realization method, at the same time, it offers electronic technology web-based course system frame which is composed of 8 modules. Guided by the studying theory of Constructivism, and supplemented by other teaching theories and studying theories, the paper adequately uses computer technology, realizes electronic technology web-based course platform based on B/S mode, and develops all modules of the course.The paper gives a detail introduction of some questions such as course content design, teaching resources design and discussion space design, provides abundant teaching resources of the web-based course, such as Flash resource library, picture resource library, related internet links, etc. Teaching resources are suitable not only to web-based instruction, but also to assistant teaching in traditional classroom teaching.The paper offers that pictures and Flash files of the electronic technology web-based course are encrypted by digital watermarking technology, which effectively solves the problem of copyright protected.Finally, the author describes the thesis's main work and characteristics from six aspects, which provide a reference for the development of other web-based courses. And the author prospects the development trend of the electronic technology web-based course, which is significant to the improvement and development of electronic technology web-based course.In this paper, the research is aid financially in stress program textbook of Northwestern Polytechnical University (M015151).
