The first sheet: Mathematics Volume 1984
This year's college entrance examination is far away from us. Many people don't know that this year's exam questions have changed a lot, especially the math group. They also put forward the slogan "Make a living question, test the foundation and test the ability", which means to increase the difficulty, thus creating the most difficult test paper in the history of college entrance examination.
How difficult is this test paper? Anhui province, which has always been among the best in mathematics, has an average score of 28, while Beijing's average score is 17, and the national average score is only 26.
Is it so difficult? A math teacher in senior three didn't believe me. After the college entrance examination, she found a copy written by herself and only got 84 points. It feels good to see this score, but in other words, many questions can't even be written by the teacher.
Many schoolmasters walked into the examination room with confidence and suddenly froze when they saw this paper. It took more than ten minutes to complete such a difficult question. Even if they finished, they were confident. In the end, many people didn't finish the questions or even check them. Many students shed tears of injustice after the exam.
Later, Anhui Province, whose comprehensive scores in science have been among the best, called 750 students to do a sampling survey. Results The scores of these 750 students on the 1984 math test paper were incredibly low, among which 8 1.5% students scored below 50 and 9.8% students scored below 20. This is not an examination question, but an advanced question in Olympic Mathematics.
It is no wonder that the media can't stand it anymore, and they have issued articles criticizing the problems such as difficult test papers, tricky test questions and uneven distribution. But you are difficult, I am difficult, everyone is difficult, and it is relatively fair.
The second sheet: Jiangxi Mathematics Volume in 2008
This year's Jiangxi math paper is difficult enough, but the last one is an important circle. This finale is as much as 14, which looks very attractive. But in 2008, none of the candidates in Jiangxi province answered all the questions correctly. The average score of 300,000 people on this question is only 0.3 1.
According to a candidate at that time, his classmates were famous scholars in the school, especially the Olympic Mathematics. His classmates finished all the other questions on the test paper in less than an hour, but he spent a whole hour on the last question and finally didn't get it right. Not to mention students, even academicians of China Academy of Sciences and famous mathematicians were shocked to attend the meeting in person, but Academician Chen shook his head after reading it.
Academician Chen shook his head not because he couldn't do it, but because he thought that such a difficult topic should not appear in the test questions, but should be placed in the math competition. Later, Academician Chen made a standard answer, up to a whole page. However, many candidates still don't understand after reading it, which shows the difficulty of this question. Presumably, after this, there will be no such difficult questions for more than ten years.
