The evaluation of the national volume B 202 1 NMET mathematics paper implements the educational policy of all-round development of morality, intelligence, physique, beauty and labor, pays attention to core literacy, and highlights the examination of key abilities, which embodies the scientific selection function and educational function of NMET mathematics. The test questions highlight the essence of mathematics, attach importance to rational thinking, and adhere to the proposition principle of literacy orientation and ability. The test questions advocate integrating theory with practice, applying what they have learned, paying attention to the important achievements of China's socialist construction and scientific and technological development, designing real problem situations, and embodying the application value of mathematics.
The reform of examination papers is steadily promoted, the relationship between necessary knowledge and key abilities is scientifically grasped, the openness of mathematical questions and mathematical thinking is scientifically grasped, and progress is made steadily, which fully embodies the basic, comprehensive, applied and innovative examination requirements. Give full play to the characteristics of the subject, take 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 economic and technological progress and development, and decide on "four self-confidences"
. The sixth question of science, based on the volunteer training program of Beijing Winter Olympics, examines the ability of logical reasoning and operational solution, which plays a positive role in enhancing students' national pride and self-confidence. The examination questions focus on promoting Chinese excellent traditional culture and guiding students to pay attention to the development of ancient mathematics in China. The ninth question of science is based on the measurement method of Liu Hui, a mathematician in Wei and Jin Dynasties in China, in his book Island Calculation, which requires candidates to infer the calculation method of island height according to relevant conditions during the measurement.
The test questions examine the comprehensive ability of candidates to solve problems by using knowledge, so that candidates can feel the process of mathematicians exploring and solving problems, fully understand the intelligence of ancient mathematicians in China, and subtly strengthen their ideals, beliefs and patriotic feelings. The college entrance examination of mathematics actively implements the requirements of the general program, increases the innovation of open questions, examines the core literacy and key abilities of mathematics with open questions, and gives full play to the selection function of the college entrance examination.
In the question of Arts and Sciences 16, the question does not give a spatial graph of "geometry", but only gives a front view of this "geometry". Candidates are required to choose two of the four given figures as side view and top view respectively, and form three views of this "geometry" with the front view. There are two correct answers to the question, which are open-ended.
Candidates can start with the side view and determine the corresponding top view with the help of the line-plane spatial relationship; You can also start from the top view and choose the corresponding side view. Different answers correspond to different thinking schemes, and the flexibility of thinking is reflected in the choice of schemes, which examines the spatial imagination of candidates and has good selectivity. Mathematics has fully implemented the examination requirements, focusing on application.
The application of probability statistics is designed based on the etching rate in chip production. The test questions require candidates to judge whether the average index of the products produced by the new equipment is significantly higher than that of the old equipment, that is, whether the research is established, according to the data of one index obtained by the new and old equipment. The test questions examine the examinee's understanding and application of knowledge such as mean and variance, and guide the examinee to care about China's intellectual creation and scientific and technological development by paying attention to the important hot issue of "chip", so as to establish a correct outlook on life and values.
202 1 College entrance examination mathematics implements the requirements of moral education, advocates the simultaneous development of five educations and implements all-round education. The examination questions highlight the characteristics of mathematics, pay attention to the educational function of mathematics culture and the rational thinking ability of candidates, which embodies the positive role of mathematics college entrance examination in deepening the curriculum reform in middle schools and improving the quality of education.
How to improve math scores, do more problems and develop good problem-solving habits?
If you want to learn math well, it is inevitable to do a lot of problems. Only by mastering all kinds of questions can you effectively improve your math scores. At first, we should focus on the exercises in books, lay a good foundation, and then gradually increase the difficulty, open up ideas and practice various types of problem-solving ideas. For error-prone questions, you should record them and contact them repeatedly. When doing problems, we should develop good problem-solving habits and concentrate, so that we can get into the best state and form habits, so that we can use them freely in the exam.
Adjust the mentality and treat the exam correctly.
During the exam, most of the questions are basic questions, and only a few questions are difficult, so we should adjust our mentality, encourage ourselves, think carefully when doing the questions, don't be impetuous, prepare well before the exam, do routine questions, don't speed up the questions in order to catch up with time, and do them in an orderly way.
