Research On Students’ Evidential Reasoning Ability In High School Chemistry Teaching

Throughout the domestic and foreign education reform,pay attention to the cultivation of students ability to ascend and values as well as the development of core literacy has become a mainstream education.High school chemistry core literacy is an important part of students’development of core literacy.Among them,evidential reasoning ability is a thinking method with chemical characteristics,and chemical principles and theories are formed on the basis of a large amount of factual evidence.Cultivating students’ reasoning ability of chemical evidence is helpful to help students effectively deal with evidence,deduce and draw conclusions,accelerate their understanding of chemical principles and theories,and improve their chemistry level.At the same time,the process of improving evidential reasoning ability is also the process of changing students’ thinking,and the ability to solve problems is also improved,which is conducive to students’ future development and of great significance.Reasoning is an important scientific way of thinking.The research on taxonomy,psychology and logic of reasoning is widely concerned,and there are many related researches.However,as for the research of evidential reasoning in chemical science,a relatively systematic system has not been constructed up to now.In this paper,starting from the logical relationship of evidence and reasoning,on the basis of literature review and analysis,chemical evidence reasoning and chemical evidence reasoning ability were analyzed,and the connotation,characteristics and cultivation strategies of reasoning ability of chemical evidence are deeply studied.On this basis,the following work is completed:（1）The system of chemical evidential reasoning ability including the connotation and characteristics of evidential reasoning ability is constructed.（2）According to the structure of chemical evidential reasoning ability,the paper designs the test paper of chemical evidential reasoning ability of senior high school,this paper probes into the chemical evidence reasoning ability of 250 senior high school students and analyzes the important factors that affect the improvement of students’ chemical evidence reasoning ability.（3）Based on the theoretical analysis and investigation results,this paper puts forward some teaching strategies to cultivate students’ ability of chemical evidence reasoning in the implementation of chemistry courses.The innovation of this study is to try to construct the high school chemistry evidence reasoning ability structure system,and on the basis of the development of testing tools,by measuring the students chemical evidence reasoning ability analysis of the present research situation and its influencing factors.
