The development of ICAI system for the individualized learning in WWW environment and its data analysis

本研究开发了基于WWW的CAI系统和基于e-mail的报告评价支持系统。该CAI系统在实用性和普及性方面得到了发展。本系统通过制作以下课件进行评估。(1)个性化学习型课件：利用神经网络为英语学习课件提供与学习者的理解水平相适应的最适合的框架。在课件学习前和学习后的确认测试有20%左右的差异。通过添加与学习者使用的客户端程序相对应的字符区分代码，可以在一个服务器程序中呈现与学习者所在国家相对应的sp图（1999）。(2)重复学习型课件：测量课件的学习时间，直到学习者完全理解问题为止。结合一些问题，学习时间的分布方程可以用beta双标称分布简单实用地表示出来。此外，还证实了估计值与实测值（2000）一致。当学习者通过电子邮件提交C编程习题学习报告时，服务器自动对报告进行评估，并将结果通过电子邮件发送给学习者。从这个结果来看，教师可以将实际工作时间减少到最高的35%，可以很容易地确认每个科目提交的报告，并且可以很容易地管理报告（2001）。

In this research, the CAI system using WWW, and the report evaluation support system using e-mail was developed.1. The CAI system in the practical and in the popular was developed. This system was evaluated by making the following courseware.(1) Individualized learning type courseware : The most fitted frame could be provided corresponding to the learner's comprehension level by using the neural network for the courseware of English learning. There was about 20% difference in the confirmation test before the learning of the courseware and after the learning. The SP-chart corresponding to the learner's country could present in one server program by adding the code of character distinction corresponding to the client program that the learner used (1999).(2) Repeating learning type courseware : The learning time of the courseware, which is repeated until the learner could understand the problem completely, was measured. The equation of the learning time distribution, which is combined with some problems, could show easily and practically by the beta bi-nominal distribution. Furthermore, it was confirmed that the estimated value agreed with the measured value (2000).2. When the learner submitted the report for the studying of C programming exercises by the e-mail, the server evaluated the report automatically, and the result was sent to the learner by the e-mail. From this result, the teacher could reduce the real working time to 35% of the maximums, could confirm easily the submitted report of every subject, and could manage the report easily (2001).
