数学与应用数学-初中数学解题中隐含条件的挖掘论文VIP免费

摘 要对数学题中的隐含条件没有挖掘或者挖掘不充分，是导致初中生解题错误的一个重要因素。本文首先概述了隐含条件的内涵及其在解题中的作用；然后按初中数学的两部分内容：数与代数、几何，归纳了初中数学题中隐含条件的类型；最后提出了培养初中生解题过程中挖掘隐含条件的能力的两个策略：加强对概念、性质及定理的教学和加强数学阅读能力。关键词：初中数学；解题；隐含条件；数学阅读1AbstractIt is an important factor for junior high school students to make mistakes in solving problems that they do not dig or not dig enough the hidden conditions in mathematics problems. This paper first summarizes the connotation of implicit conditions and its role in solving problems; then according to the two parts of junior high school mathematics: number, algebra and geometry, it sums up the types of implicit conditions in junior high school mathematics problems; finally, it puts forward two strategies to Cultivate Junior High School Students' ability of mining implicit conditions in the process of solving problems: strengthening the teaching of concepts, properties and theorems and strengthening the ability of mathematics reading 。Key words: junior high school mathematics; problem solving; implicit conditions; mathematics reading2目 录1 引 言.........................................................11.1 论文选题背景及意义..............................................11.2 文献综述........................................................12 隐含条件概述.....................................................22.1 隐含条件的内涵..................................................22.2 隐含条件在解题中的作用..........................................23 初中数学题中的隐含条件...........................................33.1 数与代数问题....................................................33.1.1 整式与分式的问题..............................................33.1.2 实数问题................
