Investigation of the Idea of Internet Teaching Materials and its Teaching/Learning Support Functions, and Research of the Effects

本研究的目的是探讨目前透过互联网展示的教材(在本报告中称为网络教材)的理念及教学支援功能。并明确了使用这些教材进行学习的效果。对网络教材进行了调查。在调查中，教师试探性地使用了国内外网络教材。并调查了在理念或学习支持功能方面优秀的教材。调查内容包括教材大纲、课程构成、课程设置、理念特点、技术特点、网络使用情况、多媒体效果等25项。从而明确了教材的特点和内容。教师对网络教材进行了评价。评价内容包括一般内容、教育价值、呈现上的技术素质、网络的技术质量和可靠性等55项，从而明确了好的网络教材的特征。将网络教材的功能分为学习信息参考功能、交流与公开展示功能、传播功能等，并进行了实验教学，明确了各功能的作用效果。进行了新型网络教材及其教/学系统的开发。开发了集信息检索、仿真、实时交流、电视会议交流等功能于一体的教/学系统。将开发的教材应用于小学和初中课程，进行了实验课。从结果中可以看出网络教材的效果。

The aim of this research is to investigate the idea of the teaching materials currently exhibited through the Internet (in this report, it is called Web teaching materials) and the teaching/learning support functions. And the effects of study with those teaching materials were clarified.1. The Web teaching materials were investigated. In investigation, teachers used domestic and foreign Web teaching materials in a tentative way. And the teaching materials that are excellent in respect of the function of an idea or study support were investigated. Investigation is 25 items, such as the outline of teaching materials, course composition, course deployment, the feature of an idea, technique, practical use of a network, and effects of multimedia. Consequently, the feature and the contents of the teaching materials were clarified.2. Teachers evaluated the Web teaching materials. Evaluation is 55 items, such as general contents, educational value, technical quality on presentation, technical quality and reliability of the network, Consequently, the features of good Web teaching materials were clarified.3. The function of Web teaching materials was classified into reference of study information, exchange and public presentation, communication, etc. And the experimental lessons were performed and the effect of each function was clarified from the results.4. Development of new Web teaching materials and its teaching/learning system was performed. Consequently, the teaching/learning systems incorporating functions, such as information retrieval, a simulation, communication on real time, and communication by the TV conference system were developed.5. Experimental lessons that applied the developed teaching materials into elementary and junior high schools courses were performed. The effects of the Web teaching materials were clarified from the results.
