High School Mathematics Teacher s Teaching Summary

Mathematics grasps the core and exercises the ability to overcome difficulties.

Shandong Lanling County No. 1 Middle School Wang Xianxin.

The final sprint before the exam is not only the consolidation and improvement of a round of review, but also the key review stage for the success of the college entrance examination.

Grab the core. The final sprint time before the exam is limited, and in order to achieve good review results in a limited time, it is necessary to focus on the core. Grasp the core knowledge points.

For example, the core knowledge points of plane vectors are vector operations (linear operations, quantity product operations) and two theorems (collinear vector theorem, plane vector basic theorem), grasp the concept of vectors driven by them, vector coordinate operations, etc., so as to grasp both the core knowledge points and the internal relationship between knowledge. Second, grasp the core mathematical ideas and methods. The core mathematical ideas and methods are mainly the ideas of functions and equations, the combination of numbers and shapes, the ideas of classification and integration, and the ideas of naturalization and transformation.

In the review, we should always pay attention to its role in problem solving, and develop the ideological consciousness of consciously using mathematical thinking methods to guide problem solving. Third, grasp the core mathematical methods. The core mathematical methods include synthesis method, analysis method, counterproof method, mathematical induction method, matching method, undetermined coefficient method, commutation method, construction method, cut-and-make method, etc.

Practice ability. 1. Practice logical thinking skills. To solve the mathematics test questions, we should rely on logical thinking to analyze the conditions and conclusions of the test questions, find out their internal relationships and determine the direction of problem solving, and put the practice of logical thinking ability in the first place in the final sprint before the exam.

2. Practice reasoning, argumentation and arithmetic solving skills. After determining the direction of problem solving, the problem solving process is mainly completed by reasoning and operation, and the ability of reasoning and argumentation and operation and solving are the key to the success or failure of the test question solution. 3. Practice spatial imagination ability.

Spatial imagination is a necessary ability to solve solid geometry questions, but the plane can also be regarded as a special case of space, and it also plays an important role in solving problems such as functions, plane vectors, solving triangles, plane analytic geometry, etc.

Difficulty. Difficulty is the main indicator that restricts the test score, overcome a difficult point can get a few more points, and try your best to overcome the difficulty in the final sprint before the test. It is necessary to overcome the high-frequency difficulties of mathematics test questions, mainly the comprehensive application of the image properties of functions, the combination of polyhedra and spheres, the synthesis of sequences and inequalities, the problems arising from the intersection of straight lines and conic curves in analytic geometry, the problems arising from the study of the properties of functions by derivatives, and the new definition questions.
