In the history of China's college entrance examination, the lowest average score of mathematics appeared in 1984, and this year's mathematics college entrance examination topic was recognized as the most difficult. 1984 during the reform of college entrance examination, the difficulty of mathematics examination increased greatly, which broke the hearts of countless candidates. In the end, the national average score was only 26, and the average score in Beijing was only 17. Most candidates can only do the above multiple-choice questions, but they can't do big questions at all. After the exam, there were many complaints in the examination room.
Not only do students think the test questions are outrageous, but many math teachers also think that these questions are beyond the outline. The college entrance examination is to test whether students have studied solidly in the past three years, but many of these math problems have never been seen, and students have never studied them at all, even the most powerful people can't do it. In order to thoroughly understand the difficulty of this exam, Anhui Province made a sample survey, and the reason for choosing Anhui Province is that its science scores have been in the forefront of the country.
750 papers were selected in the survey, among which 9.8% scored below 20, 39.7% failed to score 30, 60.5% failed to score 40, and 8 1.5% failed to score 50. The survey samples are all from science students, and their math scores are better than those of liberal arts students. If the papers of liberal arts students are extracted, the survey results may be even more tragic.
In Anhui, where science scores are better, students with better math scores are chosen, but this result is finally obtained. It can be seen that there was really a big problem with the math paper in those days.
Generally speaking, the last big question on a math test paper is the most difficult, but the big question behind that math test paper is very difficult. In the random test paper, only 1. 1% students answered these six big questions correctly, while 26. 1% students didn't write any questions and didn't get any big questions. The last big question is still the most difficult. Although the proposition intention belongs to the recursive sequence problem as before, the difficulty is not the same as before, and many high school students may not have been exposed to it.
It is said that at that time, only two people in the whole country answered this big question correctly. Naturally, these two people got high marks, and all the other students were wiped out. That year's mathematics college entrance examination paper was even criticized by the People's Education Edition, which issued a document saying that this year's mathematics examination paper did not meet the standards and principles of the college entrance examination, and it was also divorced from the requirements of current middle school mathematics teaching. The examination questions were sharp and uneven.
This year's college entrance examination has taught many people a profound lesson, especially the teacher who gave the questions paid more attention to the balance of the questions. Since then, there have never been such exaggerated college entrance examination questions. But occasionally, teachers are biased and have to ask some questions to embarrass students. For example, in the 2008 college entrance examination, there was another super question in the mathematics volume of Jiangxi college entrance examination.
This big question is worth 14 points, but the average score of all students in Jiangxi Province is only 0.3 1, and less than ten people wrote it correctly and got high marks. This problem not only gives students a headache, but many math teachers say that they have never seen such a difficult problem and can't do it. Later, the academicians of the Chinese Academy of Sciences were alarmed and sent a famous math educator, Mr. Zhang Jingzhong, to evaluate the difficulty of this problem.
Teacher Zhang Jingzhong solved the problem naturally, but he went on to say that this problem is very difficult, and it is not suitable for the college entrance examination at all, but only for the difficult math competition. He put forward a teaching idea before, instead of asking students to do a bunch of similar problems after learning a formula, which could not achieve good teaching effect at all. In fact, the best education is not to teach students how to calculate, but to let them learn to think.
However, due to the great defects in China's education system, at present, China's mathematics teaching still focuses on letting students memorize formulas and problem-solving methods, in pursuit of finding answers in the shortest time. Many students see that the same type of problem can be solved quickly, but when a new type appears, they may be at a loss, which they have never seen before.
Therefore, many mathematicians are not from traditional schools, but are trained through the Olympic mathematics competition system, which can better train students' thinking ability and mathematical thinking.
