高考数学试题往往蕴含着丰富的数学基础知识和数学思想方法.高三专题复习课中,精心选择高考试题,引导学生深入分析题目的结构、解法及其来源,通过变式、拓广和深化,广泛建立相关知识的联系,能有效地提高复习效率,促使学生更好地领会相应的数学思想方法、提高解题能力.笔者对此作了尝试,本文展示其中的一堂课,期待同行批评指正.例(2014年山东省高考理科21题节选)已知抛物线C:y~2=2px(p>0)的焦点为F,A为C上异于原
Entrance math test often contains a wealth of basic knowledge of mathematics and mathematical ideas and methods.Professional review class, carefully selected entrance exam questions, guide students to in-depth analysis of the structure of the problem, its solution and its source, through the variation, expansion and deepening, extensive The establishment of the connection of relevant knowledge can effectively improve the efficiency of review, encourage students to better understand the corresponding mathematical thinking and methods to improve the ability to solve problems. The author made an attempt, this article shows one of the lessons, looking forward to peer criticism. (Shandong province college entrance examination in 2014 Subject Selection 21) known parabola C: y ~ 2 = 2px (p> 0) the focus is F, A is different from the original C
