Research On Chemistry Teaching Practice In Senior High School Under HPS Educational Vision

The national education congress in 2018 and the two sessions in 2019 both put forward higher requirements for talent cultivation,and promoting the development of students' core literacy has become the theme of education reform in the new era.HPS(History of Science,Philosophy of Science and Sociology of Science)advocates to integrate the History of Science,Philosophy of Science and Sociology of Science into Science education in primary and secondary schools,infiltrate scientific concepts into daily teaching,and promote students' understanding of the nature of Science and the improvement of scientific literacy.Under the guidance of the concept of HPS education,HPS education should be integrated into the chemistry teaching process in senior high school,so as to promote the formation and development of students' core qualities in chemistry.The main research content includes five parts:The first part proposes the research background,significance and methods,reviews the research progress at home and abroad,and defines the core concepts and analyzes the characteristics of HPS education.The second part makes a questionnaire survey and analysis on the application of HPS education in high school chemistry teaching.The third part collects and arranges the contents of HPS involved in compulsory1 and compulsory 2 of high school chemistry textbooks of pep edition,and proposes the teaching strategy of implementing HPS in high school chemistry.In the fourth part,the high school chemistry teaching practice based on HPS education is explored,and three teaching cases of "chemical properties of metal aluminum","limits of chemical reactions" and "benzene" are selected for case analysis.By using the method of educational experiment,the teaching practice results were investigated and analyzed,and SPSS software was used to analyze the mean value of students' test scores,to test the implementation effect of HPS education in high school chemistry teaching,and to summarize the experimental conclusion.The fifth part summarizes the research conclusions and prospects the integration of HPS into high school chemistry teaching.
