The authoritative evaluation of the 221 college entrance examination questions has come

The authoritative evaluation of the 221 college entrance examination questions has come. Mathematics subjects have implemented the overall requirements of the reform of the college entrance examination content, implemented the educational policy of all-round development of morality, intelligence, beauty and labor, focused on core literacy, and highlighted the examination of key abilities, which embodies the scientific selection function and educational orientation function of college entrance examination mathematics. In 221, the authoritative evaluation of the mathematics test questions in the college entrance examination came to 1

In 221, the examination center of the Ministry of Education ordered the national mathematics test papers of literature and science in volumes A and B, the mathematics test papers of volumes I and II of the new college entrance examination (regardless of arts and sciences), and ***6 sets of mathematics test papers.

The mathematics discipline implements the general requirements of the reform of the content of the college entrance examination, implements the educational policy of all-round development of morality, intelligence, physique, beauty and labor, focuses on core literacy, and highlights the examination of key abilities, which embodies the scientific selection function and educational guidance function of the college entrance examination mathematics. Test questions highlight the essence of mathematics, attach importance to rational thinking, and adhere to the proposition principle of literacy-oriented and ability-oriented; Advocate the integration of theory with practice, apply what you have learned, pay attention to the important achievements of China's socialist construction and scientific and technological development, design real problem situations, and reflect the application value of mathematics. The examination paper steadily promotes the reform, scientifically grasps the relationship between essential knowledge and key ability, scientifically grasps the openness of mathematical questions and mathematical thinking, and strives for innovation while maintaining stability, which fully embodies the basic, comprehensive, applied and innovative examination requirements.

1. Give full play to the characteristics of the subject and highlight the educational function

The mathematics proposition of the college entrance examination always adheres to a high degree of unity of ideology and science, gives full play to the characteristics of the subject that mathematics is widely used and linked with reality, and orders educational test questions to enhance students' sense of social responsibility and guide students to form a correct outlook on life, values and world. The test questions use the great achievements of China's socialist construction and scientific and technological development as the test questions, dig deep into the subject materials of China's social and economic construction and scientific and technological development, guide students to pay attention to China's social reality and economy, scientific and technological progress and development, enhance national pride and self-confidence, enhance national identity, and enhance ideals, beliefs and patriotic feelings.

1. Pay attention to the development and progress of science and technology. The fourth question of the second volume of the new college entrance examination takes the Beidou-3 global satellite navigation system, an important achievement of China's space industry, as the test situation to design solid geometry problems, and to examine the candidates' spatial imagination ability, reading comprehension and mathematical modeling literacy.

2. Pay attention to social and economic development. Taking the training of volunteers in Beijing Winter Olympics as the background, the sixth question of science in Volume B examines the ability of logical reasoning and operational solution. Question 18 of the new college entrance examination volume I is based on the "One Belt, One Road" knowledge contest, which examines the candidates' understanding and application of the basic knowledge of probability and statistics. On the background of China's overall victory in poverty alleviation and rural revitalization, the paper gives the results of a sample survey on the income of farmers in a certain place through charts, so as to design questions and examine candidates' ability to analyze problems and process data.

3. Pay attention to excellent traditional culture. The ninth question of science in Volume B takes the measurement method in the book "Island Calculations" written by Chinese mathematician Liu Hui in Wei and Jin Dynasties as the background, and examines the examinee's comprehensive ability to use knowledge to solve problems, so that the examinee can fully realize the intelligence of ancient Chinese mathematicians. Question 16 of the new college entrance examination volume I is based on the traditional Chinese paper-cutting art, which allows candidates to experience the process of exploring mathematical problems from special to general, focusing on the ability of candidates to flexibly use mathematical knowledge to analyze problems.

Second, adhere to open innovation and examine key abilities

In October 22, the General Plan for Deepening the Reform of Education Evaluation in the New Era of the State Council, the Central Committee of China, proposed: steadily promote the reform of the college entrance examination, build an examination content system to guide students' all-round development in morality, intelligence, physique, beauty and labor, change the relatively solidified form of examination questions, enhance the openness of examination questions, and reduce rote memorization and "mechanical brushing". The college entrance examination for mathematics subjects actively implements the requirements of the General Plan, strengthens the innovation of open questions, uses open questions to examine the core literacy and key abilities of mathematics subjects, and exerts the selection function of the college entrance examination for mathematics subjects.

1. "Examples" are flexible and open. For example, the answer to question 14 in Volume II of the New College Entrance Examination is open, which provides candidates of different levels with a space to give full play to their mathematical ability and plays a very good role in examining the flexibility of thinking. There are many groups of correct answers to the second volume of the college entrance examination and the 16th question of science, and there are many solutions to choose from, which examines the spatial imagination of candidates and has good selection.

2. The problem of "bad structure" is moderately open. For example, Question 18 of Science in Volume A gives some known conditions, requiring candidates to construct a proposition according to the requirements of the test questions, giving candidates sufficient choice space, fully examining students' understanding of the essence of mathematics, guiding middle school mathematics to pay attention to cultivating the core literacy of mathematics in the teaching of mathematical concepts and methods, and overcoming the phenomenon of "mechanical brushing". Question (2) of Question 22 in Volume II of the New College Entrance Examination embodies the scientific and literacy-oriented proposition principle of "Ill-structured Problem", and makes a deep examination of logical reasoning ability, mathematical abstraction ability and intuitive imagination ability, which is not only conducive to the selection, but also conducive to the candidates to play their own mathematical ability level.

3. "Existing problems" are open in an orderly manner. For example, the design of Question 18 in Volume II of the New College Entrance Examination is open, and based on the curriculum standards, it focuses on examining candidates' logical reasoning ability and problem-solving ability, which not only reflects openness, but also reflects the accuracy and order of thinking. Question 21 (2) of the new college entrance examination (Volume I) asks about the exploration of orderly and open questions, which requires candidates to analyze and solve problems by using the basic thinking method of analytic geometry, and to examine the ability of candidates to find major contradictions in open situations.

Third, advocate integrating theory with practice, and apply what you have learned

In 221, the college entrance examination for mathematics will focus on the application and make a breakthrough. The test questions focus on integrating theory with practice, reflect the application value of mathematics, and let students feel the beauty of mathematics application. Integrating theory with practice reflects the characteristics of modern science and technology development and modern social production, and organically permeates the application of mathematical core literacy and mathematical thinking methods such as mathematical modeling, data analysis and logical reasoning, which is of positive significance to selection and education.

1. based on real situations, solving practical problems

for example, the 21st question in the second volume of the new college entrance examination is based on real problems in life science, which reflects the application of probability in life science. The test questions examine the core qualities of mathematics such as mathematical abstraction, intuitive imagination and logical reasoning, and focus on the ability of candidates to comprehensively apply knowledge and methods such as probability, sequence, equation and function to solve practical problems, which embodies the requirements of "basic, comprehensive, applied and innovative". The eighth question of science in Volume A is designed with trigonometric leveling as the background, which is one of the methods to measure the elevation of Mount Everest. The situation is real, emphasizing the integration of theory with practice. Candidates are required to correctly apply geometric knowledge such as line-line relationship, line-surface relationship and point-surface relationship to build a calculation model, and at the same time, the ability of candidates to solve practical problems by using sine theorem and other knowledge and methods to solve triangles is examined.

2. Pay attention to teenagers' physical and mental health

Physical and mental health is the core content of quality education. In the core value index system of the college entrance examination evaluation system, there are indicators of healthy emotions, which require students to have health awareness, pay attention to strengthening their physique, improving their personality and exercising their will. Mathematics test questions also reflect the relevant content. For example, the fourth question of science (the sixth question of liberal arts) in the first volume of the college entrance examination is designed in the background of teenagers' vision problems, which is generally concerned by the society, and focuses on the students' mathematical understanding ability and operational solving ability.

3. Pay attention to real production and life

For example, the second volume of NMET and the 17th question of science, take the etching rate in chip production as the prototype, design the application problem of probability statistics, examine the examinee's understanding and application of knowledge such as mean and variance, and guide the examinee to establish a correct outlook on life and values. On the background of the measurement of a physical quantity, the sixth question in the second volume of the new college entrance examination examines the understanding and application of the basic knowledge of normal distribution, and guides students to attach importance to mathematical experiments and applications.

In 221, the mathematics examination questions well implemented the ``core function of "educating people by virtue, serving talents and guiding teaching", adhered to the core value of the college entrance examination, highlighted the characteristics of disciplines and attached importance to the essence of mathematics, and played a positive guiding role in deepening the reform of mathematics teaching in middle schools. In 221, the authoritative evaluation of mathematics test questions in the college entrance examination came to 2

What should be avoided after the first day of the college entrance examination?

1. Don't discuss the college entrance examination paper, and don't discuss the answers to the questions.

here, the author uses two "don't" to answer. On the first day of the college entrance examination, Chinese and mathematics are generally tested. After the first day of the examination, students will leave the examination room one after another and meet their classmates or parents. At this time, a large number of students go out of school in order, and then most students will get together to discuss the examination papers, questions and answers of the college entrance examination.

Especially some candidates with moderate academic performance are uncertain about their answers, so they will refer to their classmates with good academic performance to see if their answers are the same as theirs. This situation and phenomenon is a big taboo after the first day of the college entrance examination. After the first day of the college entrance examination, students should not discuss the college entrance examination papers or the answers to the questions, because everyone's answers are different. When they learn that they have made a mistake, they will be very anxious and regret why they have made a mistake. Such negative emotions will remain until the next day's exam, so candidates should pay attention to it. Don't discuss the college entrance examination papers or the answers to the questions after the first day of the college entrance examination.

2. Don't judge yourself.

Many students have a habit, which was formed during the usual school exams. That is, they will evaluate their own scores after the exams to see if their estimated scores are consistent with the real scores or how much they differ. And once a habit is formed, it is difficult to get rid of it. After the first day of the college entrance examination, many students will evaluate their scores in their hearts, so as to roughly judge the results of the first day of the college entrance examination.

It's understandable if you usually score, but when you take the college entrance examination, you will have a great psychological burden. If the exam goes well, you can do the questions smoothly and the correct rate is high, which is a positive promotion. Once there is a mistake in the exam, the score will be relatively low, and the candidates will bear a lot of pressure, which is not conducive to taking the college entrance examination the next day.

Therefore, every candidate should understand the above two points. After the first day of the exam, don't discuss the college entrance examination paper, don't discuss the answers to the questions, and don't give yourself random marks, which is not good for the next day's exam. Even if the students want to discuss it, it is ok to wait until the college entrance examination is over. After all, the college entrance examination is over, and discussing the topic will not affect your performance, nor will it affect your grades. I hope you can pass the article on to your friends. Let's wish the senior three candidates in 22 all their wishes come true and have a bright future!
