Experimental Research On Teaching Strategy Of Problem-solving In The Mathematical Teaching Of High School

Problem-solving was first raised by the united states Joint committee of Mathematics Teachers in 1980. Since then, it has become a topic of general interest of the national mathematic education research and a thread of mathematic education reform. It focus on acquiring scientific Knowledge implied in the problems by solving important and practical problems. The present experimental study, under the circumstance of newly-established course reform, criticizes the disadvantages of traditional teaching method and makes the first exploration on how to realize the eductive and instructive goods of the new course reform.The paper is divided into five section .The first section: IntroductionThe paper advance that problem-solving during the class is a good choice to realize the aim of new course reform and states it in psychology and mathematics education , and point out that the problem-solving should be improved with developing situation.The second section: The basic theory of teaching strategies of problem-solvingBased on the theory of constructivism, this article revacates the essence, mental process and influential factors of problem-solving, trying to reveal the nature, motive of characteristics problem-solving study and teaching, according to this , the article puts forward the ways of problems and its features, such as circumstance, construction, positive ness , popularity, accumulation and reversibility; besides, encouragement, democracy ,coordination demonstration and conition have also been raised. The third section: The teaching strategies of problem - solvingThe teaching strategies of problem - solving, proposed in the study are:(1) innovating problem situations;(2) independent exploration;(3) exchange and discussion;(4) induce and deduce.The fourth section: The teaching procedure of problem - solvingThe teaching procedure of problem-soling highlighted in the paper is problemraising → analysis of problem→ problem solving → rational induction → problemapplication→ adjustment.The fifth section: Experiment research The conclusion drawn in the experiment is as follows:(1) Implementing the teaching strategy of problem solving takes advantage to arouse students interest in mathematics.(2) Fulfilling the teaching strategy of problem solving is helpful developing the subject status of students.(3) Executing the teaching strategy of problem solving plays a leading role in bringing about good results students will achieve in their exams.
