INVESTIGATION ON THE ACTUAL STATE OF IN-SERVICE EDUCATION OF MATH-TEACHER AND FORMULATE THE DEVELOPMENTAL STATE OF IT-IN CASE OF OKAZAKI CITY-

本研究的目的在于提出一套能引起广大数学教师兴趣和支持的中学数学学习活动指导的基本原则。它的框架遵循传统的三个观点（意义。意义重大在指导小学生数学学习活动的过程中，我们摸索出了一种新的教学方法--“后藤-豪斯基”教学法（五答法）“作为实现以儿童为中心的课堂的真正精神。后藤厚生木五答法的第一个答案是：每个学习者都能自己得到答案，即使它可能是粗鲁或谦卑的。第二，即使错误也可能有用。我们希望有很好的机会利用它进行更高级别的教学。第三，为了培养观察和发现某些自然的能力，谈论他的答案和其他人是非常重要的训练。第四，在他的回答中发现了新的意义，新的关系和新的想法，这是有趣和有趣的。第五，欣赏他的解答思想，并利用他的解答提出新问题的人是非常快乐的人。大约35年前，冈崎市的数学教师自发地聚集了一个名为“冈崎-山水数学-独学会”的数学俱乐部，意思是[喜欢学习有关学校数学书籍的人的聚会]。现在他们仍然每个月开会。以教师社会的行业认同为支撑。Dokusyokai作为在职教育是发展性的，因为它继续为会员提供新的项目，不仅讨论更好的数学教学，而且还编写报告，小册子，书籍，在实际的数学课堂上进行教学实践。

This investigation is to aim to formulate the basic principles of guiding learning activities in school masematics, which is interested and supportted by all ambitious math. teachers. Its'frame work are followed after traditional three views (Meaning. singnificance. and pschology) and well prepared problem situations with children's feeling rearities and necessities.In process of guiding children or pupil's learning activities in school mathmatics, We developed to attain a new teaching method called "Gotou-Housiki (five answers'method)) "as a realizing true spirit of child-centered classroom.First of five answers in Gotou-Housiki, we mean : Every leaner be able to get his own answer by himself even if it may be rude or hummble. (himself-gotou)Second, It may be useful even if error. we are expected to have nice chance to make use of it for higher grade instruction. (Error-gotou)Third, for sake of nurishing powers on observating and finding some nature, it is very important training to talk about his answer and others. (Talkabout-gotou)Fouth, It is amusing and entetaining to find out new meaning, new reration and flush out new idea in his answer. (Enterainment-gotou)Fifth, It is very happy person who appreciate his idea of answer and fomulate new problem using his solution.For about 35 years ago, Math-tearchers in Okazaki city gathered spontaneusly a math-club named 'Okazaki-SansuuSuugaku-DokusyoKai', which means [meeting who liked to study books concearning school mathmatics]. and still now they are continuing to meet every month. suported by tradetional approvement in teacher's society. Dokusyokai as Inservice Education is developmental, because it is continuing to offer to its member new projects for intances, not only to discuss better mathematics teachings but also to write Reports, Booklets, Books, to do teaching practise in actual math class.
