Development of CAI System for Language Education Using Machine Translation and Communication Facilities

为了促进计算机在课程教育中的应用，我们针对计算机在语言教育，特别是英语教育中的应用进行了一些具体的尝试。这是一个针对英语听说阅读和写作四项技能中的听说读阅读每项训练的CAI系统。然而，提到写作（英语作文），它只对应于一种方法，其中程序是用传统的方式估计答案描述的。在这种方法中，这样的缺陷和容易出错，其程序需要修改，每当一个新的正确答案出来，并作为一个更大的问题，其英语作文支持只有一个估计的错误答案和KR（结果的知识）信息，由于其错误判断。本研究提出利用翻译软件来弥补这些缺陷，并将翻译引擎作为翻译软件的核心部分嵌入到CAI英语训练辅助工具中，以支持英语写作。通过将翻译软件定位为CAI训练辅助工具的一个功能，学习者在CAI学习屏幕上显示他们自己键入的英语作为翻译的日语，以对抗CAI训练辅助工具指示的英语作文问题。学习者判断自己翻译的日语单词是否正确，并重复，直到最佳的日语单词组成，然后他们的英语作文肯定是固定的。

In order to promote the utilization of personal computers in the education by curriculum, we have carried out some specific trials focusing its object on the language education, particularly on English language education. These are a CAI system aiming at each training in listening, speaking and reading among the four skills in English, listening, speaking, reading, and writing. However, referring to writing (English composition), it was corresponded to only a method of which program was described with an estimated answer in the conventional manner. In this method, such defect and apt to mistake, its program is needed to revise whenever a new correct answer came out, and as a further great problem, its English compositions were supported with only a estimated wrong answer and KR (Knowledge of Result) information due to its erratum judgment. In other words, it was a from that forces to learn something mechanically.This research is to support English compositions by proposing the utilization of a translation software to make up for these defects and by embedding a translation engine which is a central part of the translation software into the CAI English training aid. By positioning the translation software as one function of the CAI training aid, learners display English typed by themselyes on the CAI learning screen as a translated Japanese against the question of English composition indicated by the CAI training aid. Learners judge whether their translated Japanese word are proper or not and repeat until optimal Japanese words are composed, then their English composition are definitely settled.
