Infiltrate China's mathematical culture into the basic examination questions.
In 20 15 years, the general feeling of mathematics (arts and sciences) test questions in Henan college entrance examination is to persist in seeking innovation in stability, pay more attention to the examination of basic knowledge and skills, emphasize general methods, and pay attention to the examination of students' application ability, mathematical literacy and learning potential. It highlights the examination of mathematical thinking methods and abilities, and there are no strange topics. The knowledge points examined are more comprehensive.
The test paper structure is consistent with previous years, and the scores and distribution of each question type remain unchanged, which meets the requirements of the new curriculum standard and examination outline. The difficulty of science mathematics is similar to last year, and it is easier to fill in the blanks in liberal arts mathematics than last year, but it is not easy to get points for big questions, and the overall difficulty is similar.
The science topic 16 guides candidates to apply the triangle solution principle to quadrilateral, and requires candidates to break away from conventional ideas, think independently and actively explore. The science test paper 19 changes the calculation of probability and expectation in previous years, but requires candidates to choose the type of regression equation independently according to the scatter chart given in the test paper to predict the publicity cost of products invested by enterprises. And the topic is novel and unconventional. These questions are based on the concepts and principles of statistics, draw conclusions through reasoning, emphasize students' understanding of the essence of mathematical concepts, and require students to have certain inquiry ability. The three-choice test questions of arts and sciences are more conventional and slightly less difficult than last year. Another highlight of this year's math test paper is the infiltration of China's math culture into the basic test questions. Explain the important role of China's ancient mathematical masterpiece Nine Chapters Arithmetic in the development of human society.
There are differences between arts and sciences, and the examination paper pays attention to the differences between arts and sciences students in mathematics learning. The liberal arts examination questions have lowered the requirements in content, topic setting and difficulty, and the topics are relatively backward, which is more in line with the characteristics of liberal arts students. Science has outstanding characteristics. On the original basis, it requires higher thinking ability and understanding of the essence of mathematics.
The whole volume examines the main knowledge of high school mathematics such as solid geometry, analytic geometry, function and derivative, sequence, probability statistics, trigonometric function, etc. Accurately grasp the key points of high school mathematics, reflect the key examination of key knowledge, and pay attention to the general methods to solve these problems. The distribution of 20 15 mathematics test questions is from easy to difficult, step by step. Choosing fill-in-the-blank questions focuses on basic knowledge and application ability. The overall difficulty distribution of the test paper is relatively gentle, the calculation amount is moderate, and the difficulty distribution of the test questions is also from easy to difficult, with a certain gradient and good discrimination.
