构造法在中学数学解题中的应用

The application of construction method in solving math problems in middleschoolAbstract This thesis researches the application of construction method in figuring out problems inmiddle school.It still gives advice for students to study construction methods.Throughout the middleschool semester As the mathematical problem became more and more difficult.The students can'tget an answer when students use traditional methods.At this time,the structural thinking method isadopted to start from a new direction,change the idea and construct a new mathematical model,which can quickly uncover the mystery.It often happens that you can't get the answer by the methodyou learned in the book.At this time,the problem can be solved quickly by constructing a newmathematical object from a new Angle by using constructive thinking method.It can be seen that ifstudents can expertly use this way.Can make oneself in the process that solves a problem twice theresult with half the effort.But there is still big difference between the ideal and the reality.In reality,students are unable to master the construction methods and find suitable construction objects.There was not enough consciousness of the importance of construction in The College EntranceExamination.So when we face with this situation.This paper discusses the application ofconstructional method in solving math problems in middle school from the aspects of constructionalfunction,constructional equation,constructional sequence,constructional geometry (It's mostly acombination of Numbers and shapes)and Construct the dual.Key Words construction method the problem solving middle school第II页
