DEVELOPING A PARTICIPATION-TYPE LEARNING ENVIRONMENT WITH MULTIMEDIA NETWORK LINK MECHANISM AND IMPROVING CLASSES

在课堂超媒体学习材料的创作中，除了顺序、各种意义和案例关系外，还开发了一种具有连贯关系的方法，以动态链接机制为基础构建了一个系统。该系统使教师能够构建多媒体网络学习环境，学习者可以在其中进行自己的学习活动，如收集信息、阅读信息、连接多个信息源、展示自己的作品以及相互交流。本文还介绍了超媒体学习材料的创作实例。此外，本文还讨论了超媒体学习材料在网络上动态链接的机制。提出了利用CGI构建动态链接机制的www服务器的方法。这种方法可以应用于互联网。在此基础上，本文在小学、初中和高中社会科学课程中实施了多媒体网络教学。举了八个例子来说明多媒体网络类。从认知科学和教学设计的角度对这些例子进行思考，可以看出动态链接机制和创作方法实现了促进学习者进行由文化实践、认知实践和社会实践组成的探究活动的参与式学习环境。最后，给出了超媒体教材的教学规划和开发流程，并对多媒体网络课堂的改进提出了建议。

About the authoring of hypermedia learning materials for classrooms, a system is formulated on the basis of dynamic link mechanism by developing a method with coherence relations additionally to the order, the various meanings and the case relations. This system enables teachers to construct the multimedia network leaning environment in which learners can take their own learning activities such as collecting information, reading them, making connections with several information sources, presenting their works and communicating with each other. Examples of authoring for hypermedia learning materials are also presented.Furthermore, the mechanism that dynamically links the hypermedia learning materials on networks is discussed. The method of constructing WWW-server with the dynamic link mechanism by applying CGI is proposed. This method can be applied to the internet.On the basis of above results, multimedia network classes in social studies and science were put into practice in elementary, junior high and senior high schools. Eight examples are taken to illustrate multimedia network classes.The consideration for these examples from the aspects of congnitive science and instructional design makes it clear that the dynamic linking mechanism and the authoring method realize the participation-type learning environment that promotes learners'inquiry activities consisting of cultural practice, congnitive practice and social practice. Finally, the procedure for instructional planning and development of hypermedia teaching materials is shown, and the improvement of multimedia network classes is proposed.
