A Practical Study On The Training Of Reasoning Ability In Physics Science By Situational Teaching Method

Physics Curriculum Standards of the Ordinary Senior High School(2017 edition,2020 revision)(hereinafter referred to as the new curriculum standard)requires that senior high school physics curriculum should cultivate students’ core quality of physics,in which scientific thinking includes model construction,scientific reasoning,scientific demonstration,questioning and innovation.Scientific reasoning is the core of scientific thinking.High school physics teaching should attach importance to the cultivation of high school students’ scientific reasoning ability.At the same time,the new curriculum standard points out that the creation of situations for teaching plays a key role in cultivating students’ core quality of physics.Context teaching method takes context as the link.By creating a life context in which students actively participate and are willing to explore,students can reason and analyze in the interaction with physical situations,understand physical laws,and improve their scientific reasoning ability.Therefore,this thesis carries out a practical research on the cultivation of scientific reasoning ability by situational teaching method.This thesis uses the literature research method to sort out the domestic and foreign researches on situational teaching method and scientific reasoning ability,and determines the purpose and content of this study.By means of questionnaire survey,this thesis understands the current application status of the situational teaching method in senior high school physics,summarizes the teaching principles,strategies and processes of the situational teaching method in cultivating the reasoning ability of senior high school physics science,and carries out teaching practice to analyze the practical effects of the situational teaching method in cultivating the reasoning ability of senior high school physics science.The resulting research is summarized as follows:(1)At present,the research on situational teaching method and scientific reasoning ability at home and abroad has been deeply involved in middle school curriculum teaching.However,there are few researches on the combination of situational teaching and scientific reasoning ability,and there is a lack of practical research.(2)Fresh students of senior high school like situational physics class and hope teachers can use situational teaching method to teach more.Physics teachers attach importance to the creation of situations in physics classroom.Different physics teachers use situational teaching methods in different teaching frequencies.(3)The situational teaching method should follow the principles of scientificity,interestingness,subjectivity and authenticity in cultivating the reasoning ability of high school students in physical science;Make good use of the situations contained in the textbook,form a logical chain physical situation,set up the problem situation skillfully to develop the hypothetical deductive reasoning ability,design a variety of situations to develop the reasoning ability of various dimensions.In the classroom teaching,the physical science reasoning ability of senior high school students is cultivated according to the teaching process of situation introduction,situation reasoning,conclusion of reasoning results and situational exercises.(4)Situational teaching has a positive effect on the cultivation of physical science reasoning ability of senior high school students,among which,it has a significant effect on conservation reasoning ability,correlation reasoning ability and hypothesis deductive reasoning ability.
