Comparative Study Of Three Versions Of Junior Middle School Physics Textbook Exercises

Curriculum reform is an important measure to promote the development of the national education and improve the status quo of education.The emergence of curriculum standards has vigorously promoted the pace of curriculum reform.The "Compulsory Education Physics Curriculum Standards(2011 Edition)" is a programmatic document of physics teaching in China,and the teaching materials are the core teaching materials and important teaching tools of the curriculum.All versions of physics textbooks of junior middle school are compiled in strict accordance with the physics curriculum standards.As an important part of the textbook,the part of exercises is a great success of the compilers.At present,there are many versions of junior high school physics textbooks used nationwide.What are the similarities and differences in the number,nature and presentation forms of exercises in different versions of textbooks? What are the differences in the degree of embodiment of exercises in the requirements of physics curriculum standards? Solving these problems has very important reference value for the preparation of textbook exercises and the rational use of teachers.Therefore,this study takes the exercises in the three versions of the textbook as the research object,and analyzes and compares the contents of the exercises in the three versions of the textbook and the consistency between the exercises and the physics curriculum standards in detail.Firstly,the paper analyzes the similarities and differences between the three versions of the exercises in terms of the number,nature and presentation of the exercises,and compare it to the physics curriculum standards.From the type of exercises,the three versions of the textbook exercises are all of the same type,with more emphasis on short answer questions and calculation questions.In contrast the number of exercises is from high to low,followed by the Shanghai Science Edition,Peoples Education Edition,Beijing Normal University Edition.From the nature of the textbook exercises,this study divides the exercises into two categories: application and understanding.Shanghai Science Edition is relatively simpler than the other two versions;in the edition of Beijing Normal University Edition,the applied exercises are basically equal to the comprehension exercises,which are of certain difficulty;the Peoples Education Edition pays more attention to the development of students' cognition and thinking,which is relatively difficult.On the one hand,from the content of the textbook exercises,the three editions of the textbooks have certain emphasis on the maps.In particular,the students will have a stronger sense of resonance with the real pictures of the people's education edition.On the other hand,the language of life in each edition of the textbooks narratives are generally higher than abstract language narratives.The three versions of the textbooks have their own merits in the matching of the exercises and language narratives.Only when two different elements are mixed together can the exercises be more suitable for the practical needs of junior middle school students.Secondly,based on the two consistency analysis tools of Webber and SEC,this paper focuses on the analysis and comparison of the consistency between the exercises of the third edition textbook and the standards of the physics course.Meanwhile using these two tools to analyze and compare the degree of agreement between the three editions of textbook exercises and the curriculum standards,the results of the research can be confirmed with each other,providing evidence for each other's results.According to the result of Webber consistency analysis,the consistency of the exercises in the three versions of the textbook with the physics curriculum standards is acceptable.In combination with the number of acceptable topics and their proportion in the consistency results of the four aspects,in contrast,the consistency degree of exercises in the third edition of textbooks is from high to low: Beijing Normal University Edition,Shanghai Science Edition,Peoples Education Edition.From the results of SEC consistency analysis,the SEC consistency index of the three versions of textbook exercises and physics curriculum standards are above 0.7,which is at an acceptable level.The consistency of the Beijing Normal University Edition is the most significant,followed by the Shanghai Science Edition.The Peoples Education Edition has the lowest consistency.The consistency degree obtained in this paper cannot fully reflect the advantages and disadvantages of the textbook exercises.The preparation of textbook exercises requires the author to carefully study the physics curriculum standards,in combination with the specific conditions of different regions of China.And there are many factors in the research that will interfere with the conclusion of the study.Finally,combined with the above analysis results of all aspects of the three versions of the textbook exercises,respectively from the compilation and use of the textbook exercises put forward some suggestions.
