A Comparative Study On Junior Middle School Chemistry Textbook Of PEP And That Of "Zhejiang Education Edition"

This research takes the chemistry part of the middle school science textbook used in most areas of the country,and the chemistry part of the junior middle school science textbook used in Zhejiang area as the research subject,The writer analyzes and compares the chemistry textbook of the two versions,to find out the similarities and differences,advantages and disadvantages of the two versions,to promote the complementary advantages of the two versions of textbooks,to enrich the contents of the two versions of textbooks,and to provide possible suggestions for teachers' teaching at the same time.In this study,the literature research,case analysis and comparison method are used to study the two versions of the textbooks.In general,the two versions of the textbook are compared and analyzed in the following aspects---the standard,the structure,the contents,the illustrations,the columns,the exercises.In detail,the“law of mass conservation” the “preparation of oxygen” and “chemical properties of metals” are selected to analyze the various elements of the two versions of textbooks according to the established analytical model.Through the macro and micro analysis of the two versions of the textbook,the author finds the following three points: first,the chemistry system of the textbook is complete,the system presents the whole chemical system,and the content structure is arranged strictly.The relative knowledge of "Zhejiang Education Edition" textbook is scattered;Second,"Zhejiang Education Edition" textbook is more interesting,rich in illustrations,and closely linked to life;The third is that the textbook has more overall knowledge,more questions,more difficulties in knowledge points,and more basic knowledge for students to understand and memorize,while the "Zhejiang Education Edition" textbook has more basic knowledge.Two versions of the textbook each have their own characteristics.After carefully comparing the two versions of the textbooks,the writer provides some possible relevant suggestions for the teacher's teaching.
