本刊将连载齐民友先生谈中学数学课程中向量、三角函数和复数的文章。齐先生是武汉大学教授,是我国著名的数学家,曾在偏微分方程等研究领域内做出过重要贡献。齐先生为培养数学人才倾注了毕生精力,他给本科生上课,指导研究生,编写偏微分方程等方面的教材,甚至在担任武汉大学校长,行政事物繁忙的四年多时间里,他仍然坚持上课,参加讨论班。他认为培养年轻人,“共同治学,一乐事也”。近年来,齐民友先生对数学教育特别关注,经常到湖北省和武汉市的中学教研室、师院、师专、教育学院等地讲学,从“集合论的基本知识”,“向量”,“中学老师进修的几个问题”,“国内外数学教育比较”到“世纪之交话数学”,题目广泛、观点明晰、思想深刻,有独到见解。(见中国现代数学家传,第四卷)目前,世界上不少数学家参与到中小学教育中来,比如日本数学家,菲尔兹奖得主小平邦彦,日本学士院院士弥永昌吉,日本数学教育学会会长藤田宏等都编写过日本中学教科书,齐民友先生也参加了我国的中小学教材编写,本刊发表的文章,就是齐先生在教材编写中的思考,相信会对老师们和数学教育工作者们有所启发。 This print will be serialized Mr. Qi Minyou talk about middle school mathematics courses in vector, trigonometric functions and plural articles. Mr. Qi is a professor at Wuhan University and a famous mathematician in China. He has made important contributions in fields such as partial differential equations. Mr. Qi devoted all his life to training math talents. He taught undergraduates, taught postgraduates and wrote some teaching materials such as partial differential equations. He even insisted on lecturing for more than four years as president of Wuhan University and busy administrative matters , Attend the seminar. He believes that cultivating young people, “joint scholarship, a happy thing ”. In recent years, Mr. Qi Minyou has paid special attention to math education. He often gives lectures to high school teaching and research institutes, teachers ’colleges, teachers’ colleges, and education institutes in Hubei Province and Wuhan City. From “Basic Theory of Set Theory”, “Vector” A few questions for further study “,” comparison of mathematics education at home and abroad “to” conversation of mathematics in the century "with a wide range of topics, clear points of view, profound thinking and unique insights. (See Chinese Modern Mathematician Biography, Volume 4) At present, many mathematicians in the world are involved in primary and secondary education, such as Japanese mathematician, Fields Prize winner Kobayashi Toshihiko, Japanese academician Miyake Changji, Japanese math Education Society President Fujita Acer have compiled textbooks of Japanese secondary schools, Mr. Qi Minyou also participated in the preparation of primary and secondary teaching materials in our country, the article published in the article, that is, Mr. Qi thinking in the compilation of teaching materials, I believe that teachers and math education The workers are inspired.
