Research On The Influence Of SSI Teaching Of Physics In Senior High School On Students’ Informal Reasoning Ability

SSI(Social-scientific issues)are some controversial social issues related to science or technology.Non-formal reasoning ability is the key ability to help students integrate into social life.Whether there is a correlation between SSI teaching and informal reasoning ability is a question worth exploring for educators.Based on the review of domestic and foreign scholars’ research on SSI teaching,that is,students’ informal reasoning ability,a total of 13 SSI related to high school physics textbooks and high school physics knowledge are sorted out,and the scientific principles,controversial principles and subjective principles of SSI teaching design are discussed.Simulation hearing,group debate and debate competition are selected as the teaching forms of SSI teaching.Then,according to the classification characteristics of SSI and combined with the characteristics of physics teaching,SSI issues were divided into three categories:human health + environmental protection issues,ethical issues and resource use issues.After that,three subjects,"The debate on Nuclear Power Plant construction","Should Nuclear weapons Development be Limited" and "Advantages and Disadvantages of space technology Development",were taken as examples to design three types of SSI teaching cases,which reflected the characteristics of using SSI as the main line,teaching through different forms and reflecting interdisciplinary practice thought.Finally,three SSI cases were designed for teaching practice in provincial demonstration schools,municipal demonstration schools and township high schools,and the results were preliminarily evaluated.It was found that: 1.SSI teaching in high school physics can improve students’ informal reasoning ability;2.SSI teaching in high school physics mainly improves students’ argumentation ability and refutation ability in non-formal reasoning ability;3.SSI teaching in high school physics has no effect on the improvement of reasoning ability and problem interest in the non-formal reasoning related ability;4.After SSI teaching,there is no significant difference in the non-formal reasoning ability of students from different levels of schools;5.After SSI teaching,there was no significant difference in the nonformal reasoning ability of students of different genders,but the SSI teaching in high school physics improved the non-formal reasoning ability of boys better than girls;6.Different forms of SSI teaching in high school physics have different effects on the improvement of students’ non-formal reasoning ability:(1)Simulated hearing can significantly improve students’ decision-making ability and verbal ability;(2)Group debate can significantly enhance students’ interest in debate;(3)Debate competition can significantly improve students’ interest in debate and speech ability...
