We regard the whole substitution of the proposition group as a generation, so generally speaking, from the end of 1980s to 2000, it basically belongs to the same generation, and half of the new members of the 1998-2000 mathematics proposition group were changed, so the style began to change obviously.
At present, the most popular teaching AIDS are mostly the works or revised versions of the first generation members, such as Li Fan, which was once the complete works of Li Er (you can laugh at the comments on the forum that Li Er has become a bad person in Li Fan, and Professor Fan Peihua is also the backbone of the first generation), and Li Wangquan (most of this book comes from an old book published by Professor Jolin Tsai and Professor Hu Jinde in 2002).
The transition from 1998-2000 group to 200 1 group can be called the second generation proposition group. Among them are Professor Zhu Shixin and Professor Huang Youdu from Gonggong University (the editing school of university mathematics magazine, with strong mathematical strength), Professor Chen from Southeast University (a leading figure in the line generation) and two professors from Dalian Institute of Technology and Mathematics. The rest are Nankai, Harbin Institute of Technology and Shangcai.
Since this period, the Ministry of Education has established a relatively mature question bank system, and the questions given by the above-mentioned proposition teachers may be reprocessed by another group of professors. There are basically no second-generation groups in the auxiliary circle of postgraduate education, except for the colleagues of two professors at the University of Technology who insist on five sets of high-quality series every year, probably because most of them have not yet reached retirement age.
The composition of the third generation group is confidential. At present, we only know that there are professors from Nankai University, South China University of Technology and Xi Jiaotong University, professors from National University of Defense Science and Technology, and professors from Institute of Mathematics of Chinese Academy of Sciences.
Starting from 20 15, the test difficulty of 15 is very mild, and there are many things that return to the foundation, and even the derivative quotient law in the textbook is tested to prove such a problem; However, 16 gave a blow to a considerable number of candidates, and the completely different types of questions and huge amount of calculation made many candidates collapse directly after the exam.
17 the overall difficulty returns to peace, and only a few questions reflect the level of mathematical thinking, so as to reflect the degree of distinction.
However, in the past, 18 was rather bleak (especially in Math II and Math III), and many candidates complained bitterly, but Bian Xiao thought it was less difficult than 16, because 16 had many new routines, which were not found in previous years, and there were all kinds of traps, but 18 had almost no new routines, and many questions looked quite good at first glance.
It can be seen that the propositional style of this group is basically mature and stable. Generally speaking, the mathematics in these four years is getting harder and easier year by year (accordingly, the difficulty of mathematics will be reduced in 19), but the overall style of the proposition remains unchanged, that is, the understanding degree and calculation accuracy of most basic concepts are investigated.
