Mathematics in the 2023 college entrance examination will fully implement the party's educational policy and promote the all-round development of students' morality, intelligence, physique and beauty; Reflect the curriculum concept of basic education in the new era, implement the reform of examination evaluation and the reform of high school education methods, comprehensively examine the core literacy of mathematical abstraction, logical reasoning, mathematical modeling, intuitive imagination, mathematical operation and data analysis, reflect the requirements of basic, comprehensive, applied and innovative examinations, highlight rational thinking, and play an important role in talent selection.
The role of mathematics in 2023 college entrance examination;
In 2023, the national mathematics volume of the college entrance examination gave full play to the role of basic subjects, highlighted the examination of literacy and ability, identified the quality of thinking, demonstrated the thinking process, set up a stage for candidates to show, and devoted themselves to cultivating talents independently, improving their quality and serving the modernization of talent selection.
1, focusing on logical reasoning literacy. For example, the seventh question in the first volume of the new curriculum standard takes arithmetic progression as the material to investigate the necessary and sufficient conditions, requiring candidates to judge the adequacy and necessity, and then prove them separately. The key to solve the problem is to use arithmetic progression's concept and characteristics to make reasoning.
The essence of the second volume of the new curriculum standard 1 1 is to judge the relationship between the coefficients of the equation according to the properties of the roots of the quadratic equation with one variable. After the derivative of the function in the problem, the properties of its maximum and minimum can be transformed into a quadratic equation with two positive roots. Question 2 1 of National Science Volume B requires candidates to conduct classified reasoning discussion according to the nature of parameters to examine the order and rigor of thinking.
2, in-depth examination of intuitive imagination literacy, for example, Volume A National Science 15 requires that the common points of a sphere and a cube edge be determined through imagination and simple calculation. On the basis of geometry, the topic of National Science Volume B 19 examines the relationship among space, line and surface. The ninth question in the second volume of the new curriculum standard examines the content of the cone in the form of multiple-choice questions. The topic is the basis of comprehensive investigation, and the four options are asked step by step. The previous options provide conditions for the later options, and each option examines the different properties of the cone, which are interrelated and focused.
3, a solid examination of mathematical operation literacy, requiring candidates to understand the object of operation, master the algorithm, explore the operation ideas, and get the operation results. For example, the first volume of the new curriculum standard 17, sine theorem, the basic relationship of trigonometric functions with the same angle, solving triangles and other mathematical contents. Used to examine mathematical operation literacy. The second book of the new curriculum standard 10 sets the intersection of a straight line and a parabola, and examines the calculation ability through the simultaneous expression of the straight line equation and the parabola equation.
