The Semantic Research Of Word Problems

Application is the practical problems expressed in athematical language,and equation is an effective model for depicting quantitative relationship between the real world,Equation makes word problems directly,and make unclear relationship clear,the questions become simple.In the elementary school,Students have studied the equation of simple word problems,But the method they used conveniently is Column formula.When they become junior middle school students,word problems became the important and difficult of the teaching,the master degree of it directly affects the high school mathematics learning.Students are familiar with the real world problems,but they can't understand the practical problems expressed by mathematical language.Some of them don't understand the topic and some don't understand the meaning of the sentence,and others don't understand the practical significance of the sentence expression,So they can't find the relations among the equivalent,this also make them can't make the equations correctly.This paper is based on the relevant theories of the native and abroad and my own teaching experience in practice.It analyzes the obstacles in the application of equations and the semantic comprehension ability of the students in solving the applied problems,So as to arouse the attention to the semantic competence cultivation of equations,This paper provides reference for mathematics teaching reform.It also puts forward some strategies to train students 'semantic comprehension ability and puts forward some suggestions on practical teaching.It is of great significance to improve teachers' teaching effect,develop human potential and improve the success rate of problem solving.
