Comment on the thinking of the first round of reviewing the proposition of mathematics in college entrance examination?

First, the delivery is accurate and comprehensive.

20 17 test paper is placed accurately, the main knowledge of high school mathematics is examined stably, the basic knowledge is covered comprehensively, the traditional questions and general methods are emphasized, and the questions are impartial and not strange. The new knowledge points in teaching guidance are mainly examinations, and the examination questions also reflect the concern for Chinese traditional mathematics culture.

Second, the starting point is low and the slope is slow.

The entrance of the test paper is wide, and the starting point of different questions is low. Both multiple-choice questions and fill-in-the-blank questions strengthen the examination of basic knowledge, requiring understanding of basic concepts and mastering basic operations. The problem solving is based on the foundation, step by step, and the gradient is appropriate. For example, Question 19 proves that the parallel relationship paves the way for the angle between the line and the plane, Question 20 solves the derivative function to bridge the range of values, and Question 22 (1)(2) is entitled to solve the problem (3) to build a stage.

Third, strengthen concepts and focus on key points.

Investigate the basic knowledge of high school mathematics such as trigonometric function, sequence, solid geometry, analytic geometry, function and derivative, and accurately grasp the key points of high school mathematics.

The test questions focus on mathematical concepts. For example, question 8 examines the basic concepts of expectation and variance, and question 12 examines the basic operation of complex numbers. The test questions also require a clear understanding of the nature of the problem and a reasonable transformation. For example, 9 questions and 10 both seek the essence of the problem from the diagram, and reasonably match the questions with different requirements to effectively improve the discrimination.

Fourth, the questions are stable and the narrative is clear.

The types of test papers are stable, the number of multiple-choice questions is fine-tuned, the basic questions are increased, the scores are refined, the score points are increased, the blank-filled questions are kept in a multi-empty form, and the intermediate scores are increased without increasing the calculation amount. The function of each question type is clear. Multiple-choice questions and fill-in-the-blank questions mainly examine basic knowledge, while analytical questions examine the ability of operation and reasoning.
