First, the principle of "truthfulness, vividness, accuracy and precision" is always implemented in peacetime teaching.

"Reality" means seeking truth from facts. Starting from the reality of our school, classes and disciplines, we should carry out teaching work at different levels, that is, teach students in accordance with their aptitude and promote them by classification. ① Pay attention to the cultivation of top students. The topic of Group B is their homework. In the process of solving problems, they are required to take shortcuts, be creative, pay attention to logical relations, and strive to solve problems completely and perfectly. This aspect is not unrelated to the high excellent rate of senior high school entrance examination results. For students with good acceptability, we should develop interest groups after class, cultivate problem-solving skills, improve flexibility and make them "sharp".

② Pay attention to the transformation of underachievers. First of all, how to motivate underachievers? Take a low starting point, give examples and exercises in the textbook, so that they can be interested in the exam and build up their confidence. Secondly, those who fail the exam will be corrected face to face, and make-up exams will be organized until they are good. ③ Pay attention to the substantial improvement of middle school students' grades. These students have a weak grasp of knowledge and often lose the ability to solve problems. Therefore, try to solve the problem strictly and seriously, so that you don't lose a lot of points in the routine. "Flexibility" means that teaching methods and means should be flexible, that is, heuristic teaching method, counseling method, discussion method, chart method, comparison method and other teaching methods and means should be adopted as far as possible. For example, for practical problems, we can generally use the chart method to analyze the meaning of the problem and list the equations to solve it. Secondly, we should teach students the mathematical thinking method of solving problems, attach importance to the cultivation of ability and strengthen the thinking training of "association, imagination and transformation". For example, students did well in the final exam of this year's senior high school entrance examination, which is inseparable from the usual emphasis on the strengthening of mathematical thinking.

"Quasi" means that the syllabus and teaching materials shall prevail. Taking teaching materials as the main line, in strict accordance with the requirements of the syllabus, we should pay close attention to double basics and training, and at the same time emphasize the standardization and accuracy of students' problem solving, and infiltrate the word "quasi" into daily teaching and practice.

"Refinement" means selecting, emphasizing, refining and evaluating. It is impossible not to engage in sea tactics, practice and strengthen. This requires careful preparation of teaching materials, teaching methods and learning methods, so as to be targeted and get twice the result with half the effort. This article starts with the word "Jing".

Second, grasp the direction, based on reality, and review steadily and solidly in stages.

Closely follow the outline and examination outline, define the review objectives, and reasonably arrange the "three rounds" general review.

① In the first round of review, the knowledge points were comprehensively summarized and reviewed, and the basic questions in the research papers compiled by the county were summarized systematically and appropriately, and the "double-base" training was appropriately strengthened. Strive for backward students to "get rid of poverty".

(2) In the second round of review, it is necessary to systematically sort out the knowledge of each unit and conduct comprehensive training, so that key issues are prominent, difficult issues are practiced layer by layer, and confusing issues are compared, so as to overcome stereotypes and practice flexibly. Pay attention to multiple solutions to a problem to cultivate divergent thinking and multiple solutions to cultivate thinking.

③ In the third round, stick to the "key points" and strive for a breakthrough. How to solve the latter two problems is the key to the success of undergraduate course. Therefore, it is necessary to master the anatomy of problem-solving methods and laws, as well as the training of thinking methods of association and number-shape transformation.
