What are the characteristics of 202 1 National College Entrance Examination B Mathematics Volume? Pay attention to real production and life. For example, the second volume of the National College Entrance Examination, Science Question 17, based on the etching rate in chip manufacturing, designed an application question of probability statistics, inspected the examinee's understanding and application of knowledge such as mean and variance, and guided the examinee to establish a correct outlook on life and values.
Attach importance to excellent traditional culture. The ninth question of science in Volume B is based on the measurement method in the book "Island Calculation" written by Liu Hui, a mathematician in Wei and Jin Dynasties in China. It examines the comprehensive ability of candidates to use knowledge to solve problems, so that candidates can fully realize the intelligence of ancient mathematicians in China.
Pay attention to social and economic development. The sixth question of science in Volume B is based on the training of volunteers in Beijing Winter Olympics, and examines the ability of logical reasoning and operational solution.
What problems should be paid attention to in college entrance examination mathematics 1? Expand the foundation and strengthen the general method.
The college entrance examination examines the basic knowledge comprehensively and highlights the key points. Grasping the foundation is to pay attention to the review of teaching materials, especially to the formation process of concepts, formulas, rules and theorems, to the limited scope of conditions and conclusions in use, to understand the typical role of examples in teaching materials, not only to do exercises in teaching materials, but also to deeply understand the mathematical thinking methods embodied in solving problems.
2. Pay attention to the educational trends and the changes of questions.
Because the new content is widely used in the current social life and production, the content that is in line with the university is the knowledge that must be possessed after entering the university, and it is the content that must be tested in the college entrance examination, so we must review and train the basic requirements such as probability statistics, derivatives and their applications, reasoning proof, algorithm preliminary, block diagram and so on. We must use new teaching ideas to teach and review senior three mathematics.
