Proposition leader, professor of Yangzhou University: Wu Xing

Deputy Head, Professor of Nanjing Normal University: Ma Hongjia, change while maintaining stability in chemistry, die, Wu Xing, you want to change all the students to Yang Da, right?

Chemistry is more abnormal than mathematics, so abnormal, the dream is broken, and it's so dirty! ! Like doing a contest, the paper maker is a butcher, and he doesn't kill pigs. Professor Zheng Ziyue said: Chemistry is not a science at all!

Coaxing us into being sinners in Jiangsu, what is it to embarrass us if we have the ability to win a Nobel Prize? Show that you are capable. How many people have been harmed by the college entrance examination system in Jiangsu, that pig brain, and come up with a 50% B.

Chemistry is killing me, and my hand in the paper is shaking again. Who gave it and let people live! ! !

It is said that mathematics is difficult, and chemistry is even more difficult. I am still a representative of chemistry class, and I feel cold when I see the topic.

Why is it so difficult? Chemistry is not good. I have done dozens of sets of comprehensive exercises, and the result directly meets this abnormal test paper. It makes people feel that the chemical era in Jiangsu is over!

Although mathematics is difficult, it is not as difficult as chemistry, which does great harm to candidates. Moreover, biology is less difficult than chemistry, which is absolutely unfair to candidates who choose materialization.

The damn paper teacher is out of line. In the future, we should just go to the chemical plant to take the chemistry class. As for the exam, we should still focus on books. Students who produce such a paper can't do well in the exam, and many students with high scores have failed in the exam. You are not harmful.

What a stupid teacher's problem is simply not large, and it has never been so difficult.

Chemistry is too difficult. What is the teacher's purpose in writing a paper? Can he show his level by crying his students? Can such a teacher make a proposition in the future? If his level is very high, then I will give him a few questions to do, which seriously violates the concept of current new curriculum reform.

Proposers take their own level as the level of students to make propositions. Such teachers should be expelled from the proposition team forever, and even be held accountable. Such people bring shame to Jiangsu.

How many students who usually study hard should the teacher who wrote the chemistry paper kill this time?

After studying chemistry in senior high school for 3 years, many of them came up with industrial problems without taking the exam. It's still a brain teaser to innovate.

I usually protect A against a+. If I am a chemical C, I will take revenge on the society and hack to death the sb who helps the college entrance examination system. ..

I am planted in chemistry, which is unfair to materialization. I really want to hack the proposer to death!

It is such a difficult test paper to ask whether the person has a cramp in his brain. All grew up eating shit.

First smash the Education Examinations Institute, and then the Cultural Revolution. The root of the problem lies in Jiangsu college entrance examination system.

The leader of the chemistry proposition group killed hundreds of candidates in Jiangsu, and the last chemistry pushed me down the abyss.

The biological difficulty is much lower than the chemical difficulty, which is absolutely unfair to the candidates who choose physical chemistry! ! !

No matter how easy it is, it is 20%A, and no matter how difficult it is, the problem is that all the students who choose chemistry are good students, and only 20%A is unfair.

The college entrance examination for science has increased the difficulty in mathematics and chemistry. But the biggest and most unexpected increase is chemistry. Although the difficulty of mathematics has greatly increased, compared with chemistry, it can really be described as "dwarfing". When I saw this test paper, I found many problems worth thinking about. First of all, we must understand; What kind of chemistry skills are students required to master in senior high school? The following aspects illustrate my point of view:

1) The overall difficulty of the test paper is seriously out of touch with the teaching practice.

From the requirements for students' chemistry study, we can be sure of the fact that "Examination Instructions" emphasizes a key word: "Basic (Ben)." From the actual learning situation of high school students in chemistry, we can also see the reason for this emphasis: a student has been exposed to chemistry since the third grade, and even if he chooses science, he will only study chemistry for four years. In addition, there are many repetitions between the teaching contents of chemistry in junior high school and chemistry in senior high school, which can be merged into a chapter of chemistry in senior high school, so the time for students to really receive chemistry education is only three years. Under this condition, it is impossible for us to ask students to have a high and precise grasp of chemistry. This is the requirement of the actual teaching situation, but unfortunately, this year's Jiangsu chemistry college entrance examination proposer obviously ignored this point: many candidates were caught off guard, and this year's chemistry test paper was full of "competition flavor". I can't play my best.

2) The background of the test questions is divorced from daily production and life.

This year's chemistry 15 and 16 respectively examined the relevant contents of experiment and chemical production. But I found that the background settings of these two topics are relatively uncommon. The 15 experiment itself is rarely touched by students, and the subsequent design experiment questions are also very poor, and the candidates' thinking is constrained by limiting spaces. I think this is contrary to the requirements of the new curriculum standard for cultivating students' innovative ability. The 16 problem itself is a failed problem. First of all, it fails to keep up with the reality of life and production. Moreover, I also thought of one thing, that is, chemical propositions around the country have been desperately pursuing new technologies and new processes this year. What's new, what comes out-all the latest processes published in chemistry magazines are moved to high school papers. Not to mention whether it is far-fetched to ask such a question. If these processes are really so close to the content of high school courses, what did the experts and doctors who designed these processes learn in college? Did they come out after four years in college and use what they learned in high school to complete such a complicated industrial production process design? Then what chemistry department should we open in the university?

3) The test paper is unreasonable, and marking it to "make up": extremely irresponsible to students!

There have been rumors over the years that if the college entrance examination is difficult this year, it will be looser when marking papers, and the harder it is, the looser it will be. One year, Jiangsu college entrance examination physics was said to be extremely difficult. Later, it was changed to adjust the test paper group: as long as there are words, you will get points! It's really ridiculous. This is the first move that undermines the rigor of teaching. Why? Your paper stumped everyone, and as a result, you randomly graded it when you corrected it. This is a contradiction in itself: since you want everyone to do well in the exam, why not rationally allocate the difficulty of the paper so that everyone can give full play to their personal standards?

4) The design of the test paper failed, and the degree of discrimination was not obvious.

The test paper is simple and can't show the degree of discrimination. Similarly, if the test paper is too difficult, it can't distinguish the level of students. Take this college entrance examination as an example. First of all, for the top chemistry students, the problem is basically a cinch. For better students, they can't solve the problem, and many people can only get the intermediate problem, and their total score is close to that of the intermediate students. That is to say, there is a "bottleneck effect", and large sections of people are crowded at 607080 points, which makes it impossible to distinguish students' grasp of knowledge. This is not conducive to the performance of most students' personal level. At the same time, this is also a disrespect for the hard work of the candidates for more than ten years-because this test paper failed to let them release the strength accumulated in 12 years.

The college entrance examination in 20 10 has passed, and success or failure can only be put into a joke, but I hope that many diseases exposed by this exam in chemistry are worth pondering by every educational participant. Children are our future and our hope. They bear too much expectation and too much pressure from all sides. But I can say that they are all good, and they are all top-notch good children! ! ! As children, they have done their best. The college entrance examination should not give them such an unfair blow. I hope that the candidates of the 20 1 1 year college entrance examination will not make the same mistake again.
