Practical Research On Classroom Infiltration Of Science Nature Teaching In High School Physics

In the 21 st century,knowledge has become an important force to promote economic development,many countries have formulated the strategy of building a strong country with talents as the core,and then the talent training mechanism with core literacy as the guide has been highly praised by all countries and has arisen a research boom.In 2017,the Ministry of Education issued the general high school physics curriculum standard(2017 Edition),which put the cultivation of students’ core literacy in the core position of cultivating people with morality.The core literacy of physics includes four aspects: "physical concept","scientific thinking","scientific exploration","attitude and responsibility of the imperial examination".Compared with the three-dimensional goal,the fourth aspect of physical core literacy "scientific attitude and responsibility" is to add the requirements of scientific essence,scientific ethics and social responsibility on the basis of the three-dimensional goal "emotional attitude and values".The core literacy points out clearly the necessity of students’ understanding of the nature of science,and also shows that the state attaches great importance to the education of the nature of science.At present,the research on the teaching of the essence of Science in the core quality of physics in China is mainly focused on the theory and less on the practice,so the research of this paper has a certain significance.Firstly,this paper has summarized the research on the essence of science at home and abroad,the current situation of the concept of the essence of science of teachers and students,the research on the essence of science of teaching materials,the teaching strategy of the essence of science and the practice of the essence of science education.In order to explore students’ understanding of the essence of Science in the core literacy,a questionnaire survey was conducted among students from a key high school directly under the central government of Ganzhou City,Jiangxi Province.The results showed that there was a significant difference between the average scores of male and female groups for the samples of the concept of Science in the core literacy,and the average scores of female students were higher than that of male students;the concept of Science in the first year of senior high school,the second year of senior high school and the third year of senior high school There is a significant difference,but there is no significant difference between senior two and senior three students,which shows that with the growth of grade and the increase of physical knowledge,students’ understanding of the scientific essence of physical core literacy has improved.Secondly,basis on the previous research,"the teaching strategy of infiltrating the essence of science education in senior high school physics classroom" was proposed in this paper.In order to test the effectiveness of the proposed teaching strategy,one or two A-level students in a key high school in Ganzhou City were selected as the research objects for a semester of teaching practice research.The experimental class adopted the teaching strategy proposed in the paper,and the control class adopted the conventional teaching strategy.The results of the teaching practice show that there is no change in the students’ view of scientific essence when the control class adopts the conventional teaching,and the students’ overall understanding level of the view of scientific essence is improved when the control class adopts the explicit teaching of scientific essence and the teaching strategies of "physics history + problem creation situation,explicit scientific essence" and "writing after class".A questionnaire survey was conducted before and after the teaching practice of the experimental class.The results show that after one semester of teaching,the students in the experimental class have a significant improvement in their understanding of scientific knowledge,relativity,empirical and non absolute objectivity of scientific inquiry,science and ethics,science and technology.Finally,a summarizes on this research and three suggestions to improve the students’ understanding of the nature of science are given: firstly,in the preparation stage,the teacher analyzes the teaching materials in depth,accumulates the knowledge of the history of physics,excavates the nature of science contained in a section of teaching content,and formulates the teaching objectives containing the nature of science;secondly,in the course of class,the teacher adopts "physics" Learning history + questions create situations,express the nature of science,and carry out explicit teaching of the nature of science;thirdly,homework is not limited to the form of brushing questions,and the form of "writing after class" can be used appropriately.
