Comparative Study Of The "Optics" Unit In Six New Versions Of Domestic Junior High School Physics Textbook

This paper selects the " optical " unit as the research object in the six editions of compulsory education physics textbooks(People ‘ s Education Edition,Beijing Normal University Edition,Shanghai and Guangdong Edition,Education and Science Edition,Soviet Science Edition and Shanghai Science Edition),which are matched with "compulsory education physics curriculum standard(2011 edition)".Taking the analysis theory of physics curriculum and teaching materials,physics teaching theory,physics and educational psychology as the theoretical basis,based on the " compulsory education physics curriculum standard(2022 edition)",core literacy,physics and students learning psychology.The above six editions of textbooks in the ’ optics ’ unit were compared by selecting the indicators of comparative research of textbooks and using educational comparative research methods.This paper is divided into three parts.The first part is the introduction,which mainly expounds the research background,research purpose and significance,the current situation of domestic research,research methods and theoretical basis of this paper,and then determines the index of comparative analysis of teaching materials in this paper.The second part is the key part of this paper.The comparative analysis was carried out from five specific aspects listed as follows of the above six versions of the textbook " optics " unit.(1)The choice of inquiry activities conforms with the Curriculum Requirements of the New Curriculum Standard of 2022;(2)Appropriate blanks in inquiry activities create space for students independent inquisition;(3)The Choice of Ways to Carry out Inquiry Activities is Helpful to Improve Students ’ Scientific Inquiry Ability;(4)Arrangement of physics experiment is beneficial to cultivate students ’ scientific inquiry ability;(5)The process of establishing physical concepts helps to improve the ability of scientific thinking for students.The third part is the summary and discussion part.According to the analysis results of the second part,this paper summarizes the advantages of the " optical " unit in the six editions of compulsory education physics textbooks,and puts forward some suggestions for the compilation of the " optical " unit in the compulsory education physics textbook.It provides necessary reference for the compilation of the " optical " unit of textbooks matching with " compulsory education physics curriculum standard(2022edition)".At last,it points out the limitations of this paper,and puts forward prospects for future research.
