Mathematics is really difficult for students who are not good at it, but it is not so difficult for students who are good at it, because no matter how difficult the math paper is, some students will get full marks and of course some students will fail. So mathematics is not the most difficult subject, but the subject with the most scores.
High school mathematics core literacy;
According to the 20 17 version of senior high school mathematics curriculum standard formulated by the Ministry of Education, the core literacy of senior high school mathematics is the thinking quality and key ability of people who have the basic characteristics of mathematics and meet the needs of personal lifelong development and social development. Specifically, it includes six aspects: mathematical abstraction, intuitive quadrant, mathematical reasoning, mathematical operation, mathematical modeling and data analysis.
Professor Wang pointed out that the outline of 1962 puts forward three abilities: operation, spatial imagination and logical reasoning. At the beginning of this century, the reform outline of senior high school mathematics curriculum developed into five abilities: abstract generalization, logical reasoning, spatial imagination, operational solution and data processing. And mathematical modeling is still a short board at present. Shortboards should be filled. Mathematical modeling emphasizes application.
