中考数学压轴题是对学生所学知识的灵活运用,以及分析、解决问题能力的全面考查,由于它的知识覆盖面广、综合性强、难度系数大,既考查基础知识和基本技能,又考查数学思想方法和数学能力,特别是注重发展学生的创新能力方面,有较大的区分度.如何才能在压轴题中提出有利于解题的问题呢?如何才能用科学的方法解决遇到的压轴题呢?按照罗增儒教授的《数学解题学引论》一书指引,笔者结合2014年张掖卷第28题从理
The mathematics question in the senior high school entrance examination is a comprehensive examination of the students’ knowledge and their ability to analyze and solve problems. Because of its wide coverage, comprehensive and high degree of difficulty, it not only examines basic knowledge and basic skills, but also examines mathematics. Thinking methods and mathematics ability, especially focusing on the development of students’ innovative ability, have a greater degree of differentiation. How can we propose problems that are conducive to problem solving in the finale? How can we use scientific methods to solve the problems encountered in the finale? According to Prof. Luo Zengru’s “Introduction to Mathematical Problem Solving”, the author combines the 28th problem of Zhang Qiang in 2014.
