近年来,数学高考逐步以知识立意转向能力立意,在全面考查学生的数学知识技能和数学思想方法的基础上,积极探索试题的创新设计。本文就近年来的高考数学解答题中的创新题型进行归类评析,以供参考。1.归纳概括型归纳概括型是指题目给出一些条件,通过观察数据特征,从特殊到一般进行归纳,或从具体到抽象的概括,得出一般性结论的一类新题型。解这类题的关键是要准确计算,仔细观察、分析特征、提出猜想,再进行论证。
In recent years, the mathematics college entrance examination has gradually turned from a knowledge perspective to a competence concept. Based on a thorough examination of students’ mathematics knowledge and skills and mathematical thinking methods, the mathematics college entrance examination actively explores innovative design of test questions. In this paper, the author analyzes and analyzes the innovative questions in the mathematics problems in college entrance examinations in recent years for reference. 1. Inductive generalization Inductive generalization refers to the fact that the title gives a number of conditions, by observing the characteristics of the data, summarizing from special to general, or from concrete to abstract summarization, to arrive at a new type of general conclusion. The key to solving such questions is to calculate accurately, observe carefully, analyze characteristics, make conjectures, and then conduct arguments.
