New Strategies For Cultivating Students' Rational Thinking In High School Chemistry Teachin

Rational thinking ability is the concentrated embodiment of human skill development,it is an important part of chemical core literacy,and also the basis of students’ participation in learning.When students use chemical knowledge to solve practical problems in life and study,they have to go through continuous analogy,observation,model construction,summary and other thinking processes.These methods play an extremely important role in cultivating students’ rational thinking ability.The Ministry of Education pointed out that rational thinking is a basic point in high school chemistry learning.Teachers in middle school chemistry teaching process,must fully realize the importance of thinking ability development,pay attention to activate and develop the students’ ability of rational thinking,in the teaching work,to grasp the chemical characteristics of thinking,to explore the rational thinking of effective training strategies,so further exploration and the innovation of the concept adapt to the new teaching mode is very important.More and more teachers have changed their focus from just on students’ basic knowledge and skills of chemistry to the development and cultivation of students’ rational thinking ability.Therefore,no matter from the perspective of the trend of education reform,or from the perspective of students’ lifelong development,it is very important to explore how to cultivate students’ rational thinking in chemistry teaching in senior high school.Through the interpretation of chemical core literacy,rational thinking and other relevant literature theories,this study understands the research status at home and abroad.On the basis of theoretical research,the present situation of rational thinking of senior high school students and the cultivation of teachers are investigated.Through the analysis of the results of the investigation,the problems existing in the cultivation of rational thinking in current chemistry teaching are found.Aiming at the existing problems,the cultivation strategies of rational thinking are put forward based on the analysis of the connotation of rational thinking.Finally,the proposed strategy is designed for teaching and practice to verify its effectiveness.Secondly,action research method is adopted to cultivate students’ rational thinking in high school chemistry teaching as the main research purpose.Considering the inconsistency of the development of high school students’ rational thinking in different grades and between different genders,aiming at the current situation of high school students’ rational thinking cultivation,the theory of rational thinking is integrated.Teaching strategies are studied from four dimensions of cultivating students’ rational thinking learning strategy,rational thinking habit,rational thinking ability level and rational thinking cognitive attitude.Finally,in view of the current situation and formation reasons of students’ rational thinking,the strategy of cultivating students’ rational thinking in different dimensions is proposed,and the teaching topics that pay more attention to the cultivation of rational thinking are designed,including "The Nature of Benzene" and "Problems of organic molecules coplanar and collinear",and the teaching practice and evaluation are carried out respectively.
