Research On The Application Of Polya's Problem-solving Thought In The Teaching Of Mathematics Problem-solving In Junior High Schools

All the time,as the main subject of students' learning,mathematics has been paid more and more attention,and solving problems is the main content of mathematics learning,it can be seen that the key to learn mathematics well is to learn how to solve problems.The new curriculum also emphasizes improving students' ability to solve mathematical problems.Polya's problem-solving thought plays an important role in the development of students' mathematical problem-solving ability,so this paper applies Polya's problem-solving thought to practical mathematics teaching,and tests the influence of Polya's problem-solving on students' problem-solving ability by carrying out educational experiments.The research objectives of this paper are two: first,to carry out experimental research on Polya's problem solving teaching in a middle school in Sujiatun District,Shenyang city,Liaoning Province,to test whether Polya's problem solving teaching can improve students' math performance;Second,a case study is carried out in a middle school in Huanggu District of Shenyang,Liaoning Province.Under the guidance of Polya's problem-solving method,targeted case studies are carried out on students of three different ability levels.This study first Sujiatun district in Shenyang,Liaoning province a experimental study of high school for three months,select the eighth grade two classes as experimental object to carry on the control experiment,the experimental results show that the poly a problem solving teaching can improve students' mathematics performance,then explain the poly a problem solving teaching in the actual feasible first-line teaching work.At the same time,the author Huanggu District a middle school in shenyang,liaoning province choose three different ability level of students in Polya's problem-solving ability promotion case study,the researchers from the students attitude towards Polya's problem solving thinking,problem solving and the problem solving content three aspects to carry on the analysis,the results showed that Polya's problem-solving ideas was generally positive influence on students.
