【摘要】 发展现代远程教育，构建终身学习体系是教育信息化的一项重要任务。现代远程教育是随着现代教育信息技术的发展而产生的一种新型教育方式。要促进基于Internet的远程教育，需要一大批网络课程。因此，开发高质量的网络课程，是当前现代教育技术工作的重要内容。由于基于Internet的网络课程与一般的多媒体教学软件的使用环境、教学功能和教学作用不同，因此，探索和研究网络课程的开发理论、构成要素、设计原则以及编写过程与方法具有重要的意义。 根据《21世纪国家网络课程建设工程》的要求，为适应新世纪教育发展的需要，本文对现代教育理论、网络及多媒体技术在远程教育中的应用进行了探索和研究。 本文对几种网络编程技术进行了比较，最后采用DHTML、JavaScript技术，同时运用动画、视频等多种媒体的形式，使教学内容以生动活泼的方式展开；采用Stream技术进行网上视频的传播；以Flash及其Action的强大功能制作的虚拟实验室，形象逼真，交互性强；采用ASP／ADO技术，实现与数据库的连接和访问，开发了交互性强的网上测试系统。 本网络课程突破传统的教育模式，将网络课程、网上实验、视频点播、电子教案、网上测试、化学视野等有机的融为一体，结合人—机、人—人交互活动，构成学生学习的“十字交叉”立体结构网。利用先进的网络技术，发挥多媒体技术、交互技术的优势，创建了有效的远程个体学习环境。其中采用的实现技术及问题的解决，对促进网络课程建设的发展将具有长远的意义。更多还原

【Abstract】 Developing modern distance learning and establishing a life-long learning system is an important task for education informationization. Modern distance learning is a new-patterned educational method accompanying the development of modern educational information technology. In order to promoting distance learning based on Internet, a batch of web courses is needed. Therefore, developing web courses of high quality is an important content of current work of modern education technology. Because Internet-based web courses are different from ordinary operating environment and educational function of multi-media education software, thus, it bears significant meaning to explore and to research the development theory, composing elements, designing principle and compiling process of web courses.According to the requirements of National Web Course Construction Project in 21st Century, the application of modern education theory, web and multi-media technologies in distance learning is explored and researched in this thesis.In this thesis, several web-programming technologies have been compared; DHTML and JavaScript techniques are adopted in the end. At the meantime, the application of several media forms such as motion and video, etc. enables teaching contents to be taught in more lively form. Also, stream technique is adopted to transmit video image online. The Virtual Lab produced by Flash and its Action function possesses vivid image and strong interactive feature. The ASP/ADO Techniques are adopted to realize the connection and visit to database, and to develop online testing system with powerful interactive features.This Web course breaks through the traditional educational model, integrates web course, web experiment, video ordering, electronic teaching plan, online testing and chemical outlook together; utilizes interactive activities of person-computer, person-person, and constructs Cross-Crossing cubic structure network for students’ learning. With advanced network technology, multi-media technology and interactive technology, this web course established an effective distant individual learning environment. Therein to, the realization technology adopted and problems resolved will have far-reaching effect on promoting the development of Web course construction.更多还原
