2012年云南省初中学业水平考试数学卷的第23题是全卷的压轴题,全题共分三个小题,各小题间承接明显,较好地实现了对初中数学基础知识、基本技能和以数学思维为核心的能力考查.特别是第(3)小题,综合程度高,难度进一步加大,是一道几何与函数综合的探究题,要求学生具备分类讨论的思想,这无疑对学生的数学思维提出了较高的要求.本题在编排上具有起点低、坡度缓、难点分散,但综合程度高的特点,属于能力提
The 23rd question of the mathematics volume of the 2012 Yunnan Junior High School Proficiency Test is a full-volume finale title. The whole title is divided into three sub-questions. The sub-questions are obvious, and the basic knowledge and basic skills of junior middle school mathematics are well achieved. And the ability to take mathematics thinking as the core of the examination, especially the first (3) topic, a high degree of integration, further increase the difficulty, is a combination of geometry and function of the inquiry question, requires students to have the idea of classification discussion, which is undoubtedly for students The mathematical thinking raises higher requirements. This topic has a low starting point, slow slope, and difficulty in decentralization, but features a high level of comprehensiveness and is an ability
