Research On The Optimization Of High School Physics Unit Assignments Based On Core Literacy

In 2018,the newly revised curriculum standard of physics for ordinary high schools was published,through this optimization,the core quality of the subject was condensed based on the nature of the subject.Compared with physics teaching,the reform of physics homework is relatively slow.Most physics teachers will not go through certain screening of homework,and students will have a greater overall academic burden due to more subjects.Existing physics assignments do a good job in testing knowledge,but they are often limited to the level of physical knowledge.The content is relatively dull,lacking the connection with life practice,the type of questions is often single,lack of diversity,the only answer lacks certain openness,the form of investigation is limited to writing,and lack of certain practicality.In this case,students often practice their homework mechanically in order to get high marks.In the short run,the scores may be improved,but students often do not realize the pleasure of physics homework.Naturally,they are not very enthusiastic about physics learning,and it is difficult to apply what they have learned in the face of practical life problems.Core literacy focuses on students' lifelong development,aiming at cultivating students' correct values,scientific thinking mode and the ability to deal with problems and solve problems.It is obvious that the current physical homework can not fully meet the requirements of core literacy.Therefore,in order to better enhance students' core physical literacy,it is necessary to optimize the physical homework.This paper is divided into six parts: The first part is the introduction,including the research background,the significance of the study,the status quo of the study,the objectives and contents of the study,the ideas and methods of the study.The second part is the definition of related concepts and optimization dimensions,firstly,it defines the related concepts of physical core literacy,physical unit assignment and optimization.Secondly,it introduces the dimensions of optimization assignment,including physical core literacy and related requirements,relevant theoretical basis and students' actual situation.The third part is to better understand the actual situation of students,design and implement the survey program,by means of questionnaires to students and interviews to teachers,the present situation of physics homework in senior high schools is comprehensively and deeply understood.Through the analysis of the survey and interview results,the present situation of physics homework in senior high schools is summarized from students' ideas,teachers' views and the quantity,quality and types of physics homework in senior high schools.The fourth part is the optimization design of the physical unit operation in Senior One.According to the optimization dimension,the corresponding optimization strategy is designed.The optimization strategy is embodied in the content,type and evaluation of the physical unit operation.Finally,the specific optimization and evaluation of the two units operation are carried out.In the fifth part,the optimized unit assignments were tested in the form of practice,and the contents of the corresponding chapters were arranged every week.SPSS software was used to compare and analyze the scores of the students in the experimental class and the control class before and after the test,and questionnaires and sampling interviews were used to test the implementation results.The sixth part is the conclusion,innovation,deficiency and prospect of the research.The research results of this paper are summarized as follows: Firstly,according to the investigation of the current situation of the physical homework in the practice area,it is found that it is necessary to optimize the type and evaluation of the physical homework in the practice school.Secondly,on the basis of core physical literacy,combined with the constructivist knowledge view,the intelligent category of multiple intelligence theory and the actual situation of students,the corresponding optimization strategy is formulated,and the optimization strategy is embodied in the selection of homework content,the improvement of types and the reference of evaluation.Thirdly,for the author's optimized homework,it gives a detailed evaluation,which provides some research ideas and models for future generations to study the exercises of core literacy.Finally,through practical research,the optimized physical unit operation of Senior One is tested in a practical way,and the validity of the optimized unit operation is verified.
