Study of CAI system for the university and adult education with a view to adapting to the information oriented society

当今社会，高等教育和成人教育是与高学历社会和老龄化社会相联系的信息化社会的重要主体。本研究从建立适合当前社会环境的大学和成人教育学习环境入手，最终设计并实现了学习者可以随时随地任意自主学习的CAI （Computer Assisted Instruction，计算机辅助教学）系统。本研究包括三个主题；教学策略、教材及其管理。从教学策略的角度出发，根据学习者的理解水平，设计了控制学习过程及其文本的框架式cai。具体来说，我们建立了一个基于模糊集合理论的试错学习模型，一个基于语义网络的复合概念学习模型和一个基于人工智能的行动者模型。此外，为了确认CAI教学策略的能力，我们编辑了一些教材，如国际金融学科、计算机素养教育、食品营养教育和美术教育。在教材和软件的管理上，数据库将这些小的分段（所谓的框架或模块）存储起来，并重新组合成一个层次结构以供实际使用。数据库中的框架和模块与文件传输相匹配，适合通过局域网使用CAI的远程学习者。本研究开发的CAI模型具有信息管理、信息交流和信息处理等功能，有望应用于各种应用领域。同时，从基础设施在信息社会中有效应用的角度来看，由于信息网络和多媒体技术的未来发展，本研究的成果将具有实用性和现实性。少

Nowadays, university and adult education are important subjects of the information oriented society in association with the highly educated and the old aged society. This research was started to establish learning environment of the university and adult education suitable to the recent social circumstance, and we finally conluded the research with the design and implementation of the CAI (Computer Assisted Instruction) system by which learners can arbitrarily have their self-learning at any time and any place.The research consists of three subjects ; instruction strategy, teaching materials, and their management. From the viewpoint of the instruction strategy, we designed frame type CAIs that control learning process and its text in correspondence with the grade of learner's understanding. Concretely speaking, we have formulated a trial-and-error learning model based on the fuzzy set theory, and a learning model about composite concepts by semantic networks and an actor model of the ar … More tificial intelligence techniques. Furthermore, in order to confirm the ability of the instruction strategies in the CAI,we have edited some teaching materials such as a subject of international finance, computer literacy education, food-nutrition education, and fine art education. On the management of teaching materials and softwares, a database stores these small fractionalized segments (so called frames or modules), and reassembled into a hierarchical structure for actual use. The frameworks and modules in the database matches file transportation, and suits remote learners who use the CAI through LAN.The CAI model developed in our research is expected to be used in various applications, because the CAI consists of the functions of information management and communication as well as processing. And also, from the viewpoint of effective application of infrastructure in the information oriented society, the products of this research will be practical and realistic owing to the future advancement of the information network and multimedia technologies.
