Mathematics learning of senior high school students is inseparable from problem-solving training,and the level of problem-solving directly affects the level of mathematic achievement.Therefore,starting from the difficulty of solving mathematic problems of senior high school students,this paper investigates and analyses the causes of the difficulty in solving mathematic problems,and then puts forward relevant countermeasures.Its main purpose is to help senior high school students overcome it by putting forward some practical teaching strategies.First of all,through learning the relevant literature,we can understand the theoretical knowledge of mathematical problem solving.such as polya’ problem solving theory,also read a lot of outstanding thesis about the problem solving,and it is concluded as following aspects: The grasp of basic mathematics knowledge does not arrive the demand level,the mathematic computation is not good enough,the thought barrier,the problem solving standard question as well as the problem solving reflection does not arrive and so on.Then,for the sake of accurately understanding the causes of high school students’ difficulty in solving mathematical problems,the author selected a high school in yan ’an to conduct a questionnaire survey on the causes of high school students’ difficulty in solving problems in mathematics.In addition,the author also interviewed excellent high school teachers on the causes and countermeasures of high school students’ difficulty in solving problems.Through the analysis of the questionnaire data,the collation and analysis of the interview results of the teachers,finally the causes of high school students’ difficulty in solving math problems are summarized: psychological barriers to deal mathematical problems,knowledge barriers,operational barriers,thinking barriers,habit barriers to solve mathematical problems.Finally in order to change the present situation of high school students’ mathematics problem solving difficulties,I put forward the corresponding strategies to overcome the students’ problem solving of all kinds of obstacles respectively from the angles of teachers and students,such as teaching through revealing the essential knowledge to overcome obstacles in knowledge,through variant practice to overcome operational obstacles,through expose the thinking process to overcome the thinking obstacle etc.these policies and measures is convenient to apply,also can facilitate high school teachers in the teaching implementation.In addition,it also combines specific teaching cases to prove the rationality of the proposed strategy,so as to provide some help for front-line teachers in problem-solving teaching,but also help students gradually overcome the difficulties of mathematical problem-solving. |
