At the beginning of this century, the new schools in China have just started, and the educational system and teaching materials are mostly copied from Japan or Europe and America. Hu Dunfu and members of Rieter Society feel from personal experience that one of the ways for China to strive for academic independence is: "To ensure that science beginners can get rid of the shackles of foreign languages and get more reference materials. Scholars have studied a lot, and self-energy groups tend to invent a way. " "Today, starting from middle school textbooks, it is more appropriate to gradually reach reference books, step by step, and even advanced learning. The materials can be simple and detailed, and the structure need not be grand, but the opinions must be original, so that middle school students can benefit from observation first; Go to Yingke and introduce the treasure forest. " Therefore, an important feature of Datong teaching is to mobilize teachers to compile teaching materials and teaching reference books. The "Editorial Department of Datong University Series" headed by Hu Dunfu was established, with 14 members, all of whom are knowledgeable in various subjects. Hu Dunfu practiced, and soon after Datong was founded, he co-edited junior high school mathematics textbooks with his wife Hua Guixin (a scholar studying in Japan); In the 1920s, he co-edited one volume of Arithmetic and two volumes of Geometry with Wu Zaiyuan. The Geometry of Senior High School, which they co-edited, was written for the new textbook "Mixed Mathematics" adopted by junior high schools at that time. This book can make up for the unfinished course of geometry in junior high school and is adopted by many schools. In 1930s, he co-edited Plane Geometry and Solid Geometry with Rong, and Hu Dunfu's New Middle School Geometry was approved as a high school textbook by the Ministry of Education. 1935 The Guidance of Integral Equation, which was jointly translated by He, Fan Huiguo and Gu Cheng, was listed as one of the earliest "university series" in China by the Commercial Press. In the 1940s, his English Collection (volume 1-5) was approved by the Ministry of Education as a textbook for junior high schools in China. In addition, he prefaces or revises many textbooks and teaching reference books. His work laid the foundation for the construction of early middle school textbooks in China.
The textbooks compiled by Hu Dunfu are generally tried by themselves, which is a combination of scientific theory and practical experience. In Datong, in addition to mathematics, he also taught English, Latin, philosophy, Chinese studies, physics and other courses. He will teach any course without a teacher, and the teaching effect is very good. Wang Daohan, the former mayor of Shanghai, said, "I have heard Professor Hu Dunfu teach calculus. Mr. Hu is knowledgeable and his lectures are clear. When the school was founded, it had a beautiful meaning in the name of' Datong'. Datong is very famous and has trained many talents. " At Shanghai Jiaotong University, Hu Dunfu has at least two calculus classes in each class. Professor Li and Professor Huang, his students in the 1930s, recalled: "He has been teaching this course for many years, but he still has to prepare lessons before each class and never goes into battle carelessly. Students are willing to listen to him. "
In charge of the Mathematics Department of Shanghai Jiaotong University 15 years (1930-1945). At the beginning, I started to recruit math undergraduates. He is the only 1 professor in the whole department, and has offered a series of specialized courses. By 1936, there are 5 professors and 2 lecturers, and the curriculum of the Department of Mathematics has basically formed a system. The department pays equal attention to theory and application in teaching, not only to basic theory, but also to the application of combinatorial engineering discipline. Starting from the second grade, the course "Mathematical Problems" is offered every semester to guide students to study important problems or new fields in mathematics and cultivate their scientific thinking and creative spirit. The second grade also offers the course "History of Scientific Thought", which aims to let students know the origin of scientific thought and the development of various important sciences. These courses have played a certain role in broadening students' horizons and cultivating their independent research ability. Hu Dunfu realized that the guarantee of teaching quality lies in the improvement of teachers' academic level. Because of the busy administrative affairs and little consideration, he encouraged and actively supported teachers to participate in academic activities and conduct scientific research. Before the Anti-Japanese War, the teachers of the Department of Mathematics of Jiaotong University published more than 1 10 articles in various journals, which was the most fruitful department of the School of Science of Jiaotong University. The research content involves calculus, series, function and modern mathematics. Because of his rich knowledge, during the period of War of Resistance against Japanese Aggression, he led the teachers and students to make joint efforts, not only offering all the courses required by his department, but also offering mathematics courses for other departments.
Professor Su commented on Hu Dunfu in May 1993: "Hu Dunfu is very kind and smart. At that time, it was said that Mr. Hu Dunfu was the best mathematician in Britain and his literature was also very good. " "Mr. Hu Dunfu is a good educator, because he didn't write any papers, so he was not so famous at that time." 194 1 year, the Ministry of Education of Chongqing National Government set up departments to hire professors all over the country to reward those who have been professors in universities for more than 10 years, who have made outstanding achievements in teaching and made special contributions to this subject. After repeated deliberation, it was decided that the first batch of professors hired by the Ministry would select 30 professors from 24 disciplines, including 2 professors from 6 disciplines including China Literature and Mathematics, and 0 professors from other disciplines. Among these 30 people, two others were not officially announced in the occupied areas at that time. Hu Dunfu was selected as one of two professors in several disciplines and occupied areas. In the list of records, Professor Hu Dunfu actually only has 1, which is a full affirmation of his teaching achievements in the past 30 years.
