A Study On Students' Physics Core Competence Development Based On Excerpts From Junior-High-School Textbooks Of Several Versions

Textbooks,in daily teaching activities,has a closest relationship with teachers and students.The compilation features and content settings of textbooks can reflect curriculum concepts and core literacy systems that adapts to students' lifelong development.All those will affect teachers and students in a certain degree,especially the acquisition of a certain subject,the development of learning ability and the development of emotions,attitudes,values,and even the implementation of students' core literacy development goals.Therefore,textbooks is an important medium for teachers to carry out core quality education.As a result,the thesis aims to explore the implementation of the development of students' core quality education in the mechanics part of several versions of junior middle school physics textbooks,analyze the core literacy of physics combined with physics textbook,and compare the implementation of core literacy of physics in junior high school physics textbooks.The thesis,based on the core literacy of physics discipline,takes literature and comparative methods to compare the mechanical part,which plays an important role in junior high school,in physics textbooks of the latest Beijing Normal University edition,PEP edition,Shanghai and Guangdong editions,Shanghai Science edition,and Jiangsu Science edition.The thesis strives to outline the current situation of core literacy of physics discipline in the textbook,and tries to provide some reference for current physics education in junior middle school.It also clarifies the advantages and disadvantages of existing textbooks in embodying the core literacy system and strives to provide useful insights on the secondary development of textbooks and school-based compilation,and also provides some suggestions and ideas for the compilation and revision of future junior middle school physics textbooks.The thesis consists of five chapters:The first chapter is introduction,mainly describing the research background,explaining the research purpose and significance of this paper and the research status at home and abroad and finally determining the research content,methods,technical routes and innovation.The innovation of this thesis is that the author compare and analyze the textbooks from the perspective of the development of students' core qualities,so that the textbooks can better exert the media function of infiltrating core literacy education,which opens up a new perspective on the analysis of textbooks;The second chapter is theoretical study,mainly introduces the connotation and structure of core quality,core literacy of physical discipline,as well as the relationship between the both.Through the analysis,the core quality and core literacy of physical discipline are complementary with each other.Citizen common core quality can strengthen and guide the implementation of subject core literacy and the implementation of subject core literacy opens a new way for the realization of the citizen common core quality.The third chapter is a comparative study among lead-in system,activity system,example system,after-class exercise system and feature column of the mechanics partfrom five sets of junior-high-school textbooks from the perspective of physics concept cultivation,science thinking cultivation,experiment and exploration cultivation and sense of responsibility cultivation.Research data have been expressed with table,and transformed into bar graph,as the conclusion of the implementation situation of core literacy of physics of the five sets of textbooks.The fourth chapter is introspection and suggestions.Based on research results of Chapter Three,the author has found that the five sets of textbook have emphasized the permeation of physics history,to cultivate the core literacy of science attitude and responsibility,and also have emphasized the core literacy of “experiment and exploration” for paying close attention to the relation between physics knowledge and life,industry.Besides,the five sets of textbook have emphasized the immersion of physics knowledge and other disciplines and methodologies,which has displayed the emphasis on comprehensive science thinking.However,there is proportional imbalance among the four elements of core physics literacy.Lateral comparative study of the five sets of textbooks indicates that,the emphasis on the core literacy of science thinking is not enough in the versions of People's Education Press,Shanghai Science Technology Press-Guangdong Education Press,Shanghai Science Technology Press and Beijing Normal University Press,and this should be taken seriously.In this chapter,there are also suggestions on textbook compilation and revision for junior-high-school physics,and on optimizing the utility of textbooks for teachers,that's,to seek a balanced proportion among the four elements of core physics literacy in the textbook to promote a balanced growth for students.These suggestions are to add exercise types,to enrich content,to diversify assessment methods for the purpose to cultivate the core literacy of “science thinking”,to pursue the quality and quantity of activities and to diversify activity types for a better cultivation of the core literacy of “experiment and exploration”.Besides,similar columns should be merged for an optimal column setting.Suggestions on optimizing textbook utility include teachers' blending multiplex sources,updating,expanding and recombining the content of textbooks,tailoring knowledge based on students' cognition features,creating teaching scenarios,adding opportunities of studying problems with scientific methods,paying attention to students' experiences of science attitudes and values,and enriching physics development history.The fifth chapter is the conclusion and implications for future study.Research results and limitations in this study have been summarized,and the discussion of reasons,implications and suggestions for future studies has also been conducted.Due to the lack of theoretical basis,vision and research ability of the author,the understanding of the elements of core physics literacy and parts of the content of the textbooks in this study is not good enough.Besides,limiting the research subject to mechanics is not scientific.These problems and limitations will be the direction for the author's endeavor,and the author will make efforts to search for better methods for the cultivation of core physics literacy in the future job with positive attitude.
