Various problems in mathematics education and developments of new materials.

近年来微型计算机的迅速发展也对教育产生了很大的影响，人们迫切希望在学校中找到它们的用武之地。在我们的研究中，主要采取了以下几点。(1)挑选出能最有效地用微型计算机处理的教材。通常，人们使用微型计算机作为设备，让学生练习他们的演习，但在我们的研究，我们希望找到微型计算机的使用，使学生变得更吸引人的研究。意外事件的发生，材料的现象学解释，学生自己发现新的事实等等，这些都是我们对材料发展的看法。(2)屏幕上的图片，设备发出的声音似乎对学生很有吸引力。从这个角度来看，激光视盘似乎非常有效。在数学中，我们如何使用激光光盘？特别是，我们如何在课堂上使用它们，而不是在个人学习中？我们设计了一个以激光视盘机为主体的计算机辅助教学系统。(3)中学教学资讯学之研究（4）学生个人档案之处理。制定学校时间表编制方案。

Recent rapid developments of microcomputers have excercised strong influences in the education too, and it is urged to find their good use in schools. In our research, following points were mainly taken up.(1) To singly out teaching materials which are most effectively treated by the use of microcomputers. Usually, one uses microcomputers as apparatus to make tudents practice their drills, but, in our reseach, we hoped to find the usage of microcomputers so that the students become more attracted to the studies. Occurence of unforeseen events, phenomenological explanation of materials, discoveries of new facts by students themselves, etc. These are our aspects for the developments of materials.(2) Pictures on the screen, sounds made be devices seem to be very attractive for students. Laser discs appear to be very effective from this point of view. In mathematics, how can we use laser discs? Especially, how can we use them in the class lessons, not in the personal studies? We worked out a system of CAI having laser disc units as its main part.(3) Studies of teaching informatics in high schools(4) Processing of personal records of students. Development of programs for making up time table in schools.
