Comment on the 221 National Mathematics Test Paper B

The college entrance examination for mathematics has ended. I have sorted out the evaluation of the national B-volume mathematics test questions. Let's have a look!

evaluation of the mathematics test questions in the national second volume

The mathematics of the college entrance examination in 221 carried out the educational policy of all-round development of morality, intelligence, physique, beauty and labor, focused on the core literacy, and highlighted the examination of key abilities, which reflected the scientific selection function and educational function of the mathematics of the college entrance examination. 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 has been steadily promoted, the relationship between necessary knowledge and key abilities has been scientifically grasped, the openness of mathematical questions and mathematical thinking has been scientifically grasped, and the innovation has been sought while maintaining stability, which fully embodies the basic, comprehensive, applied and innovative examination requirements. The test questions give full play to the subject characteristics, 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 economic, scientific and technological progress and development, and decide on "four self-confidences"

. The sixth question of science is based on the training program of volunteers in Beijing Winter Olympics, which examines the ability of logical reasoning and operational solution, and plays a positive role in enhancing students' national pride and self-confidence. The examination questions focus on promoting the excellent traditional culture of China 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 Chinese mathematician in the Wei and Jin Dynasties, in his book "Island Calculations", which requires candidates to infer the calculation method of island height according to the relevant conditions in the measurement process.

The test questions examine the examinee's ability to solve problems by comprehensively applying knowledge, so that the examinee can feel the process of mathematicians exploring and solving problems, fully realize the intelligence of Chinese ancient mathematicians, and subtly strengthen their ideals, beliefs and patriotic feelings. The college entrance examination of mathematics subjects actively implements the requirements of the General Plan, increases the innovation of open questions, uses open questions to examine the core literacy and key abilities of mathematics subjects, and gives play to the selection function of the college entrance examination.

In the 16th question of literature and science, the question does not give a spatial figure of a "geometric body", but only gives a front view of this "geometric body". Candidates are required to choose two of the four given figures as side views and top views respectively, and form three views of this "geometric body" with the front view. There are two correct answers to the questions, which are open.

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 with the top view and then select 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 selection. Mathematics has fully implemented the examination requirements, and focused on its application.

in question 17 of arts and sciences, 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 value of the 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. The test questions examine the examinee's understanding and application of knowledge such as average and variance, and guide the examinee to care about China's intellectual creation and scientific and technological development, and to establish a correct outlook on life and values by paying attention to the important hot issue of "chip".

In 221, the college entrance examination for mathematics will implement the requirements of moral education, advocating five educations and carrying out all-round education. The examination questions highlight the characteristics of mathematics, pay attention to the educational function of mathematics culture, and focus on the rational thinking ability of candidates, which embodies the positive role of the college entrance examination for mathematics 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, and master all kinds of questions skillfully, so as to effectively improve math scores. At the beginning, you should focus on the exercises in books, answer the basics well, then gradually increase the difficulty, open up ideas and practice various types of problem-solving ideas. For the types of questions that are prone to errors, you should record them and contact them repeatedly. When doing problems, you should develop good problem-solving habits and concentrate, so that you can get into the best state and form habits, so that you can use them freely in the exam.

Adjust your mentality and treat the exam correctly

When taking an exam, most of the questions are basic, and only a few 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 regular questions, don't increase the speed of doing the questions in order to catch up with time, and do it in an orderly way.
