The Study Of Developing Critical Thinking In High School Mathematics Teaching

Since the last century,many western countries have realized the importance of critical thinking and carried out a comprehensive critical thinking education activities.At present their critical thinking education has developed very deep.In the 21 st century,with the rapid development of science and technology,our country also began to attach importance to the cultivation of critical thinking,In the field of higher education,as well as some important science education,is to develop critical thinking.The cultivation of critical thinking,which is a systems,needs to start from basic education,but we lack of research and practice in this respect.This study aimed at how to cultivate the critical thinking questions in high school mathematics teaching.First of all,this passage will explain the concept of critical thinking,and expounds its relationship with the thinking and mathematical thinking.And then I analyze the status of the student's critical thinking by the questionnaire.On this basis,I propose the teaching significance,teaching principle,teaching focus and teaching strategies of developing the critical thinking,and test training methods by comparing the teaching result between the regular class and experimental classes.The last process is to have a in-depth reflection on the train.The main result of this study has the following two points:First,the teaching key points will be raised,including questions of critical thinking asking questions,reflecting,the cultivation of metacognitive ability.Second,the strategies of cultivating the critical thinking is put forward in different types of math class,including mathematics concept teaching strategy,teaching strategies of mathematical reasoning and mathematics problem-solving teaching strategies,etc.
