Comparative Analysis Of Chemical History Contents And Development Of Curriculum Resources In High School Chemistry Compulsory Textbooks

The new round of curriculum reform requires the cultivation of students ' accomplishment in all aspects,and the education of Students ' chemistry history is the most effective way to cultivate students ' scientific accomplishment.Learning the knowledge of chemistry history can not only enhance students ' interest in learning chemistry,generate initiative for learning,but also give full play to students ' subjective status.The most direct way for students to study chemistry history is chemistry teachers,and teaching materials are the most direct and main curriculum resources,teaching materials are also the main basis for teachers to obtain the history of chemistry teaching,so it is of far-reaching significance to analyze the main presentation methods of chemical history in teaching materials.Based on the theoretical discussion of the connotation and function of chemical history,this paper selects the Chemistry teaching materials published by the People's Education publishing house and the chemistry textbooks published by Shandong Science and Technology Press as the research object,mainly taking the compulsory teaching materials as an example,using text analysis method,comparative research method,The case study method and Leite analysis scale compare and analyze the presentation mode,Content Selection and learning mode of chemical history in the two version textbook,draw the deficiency of chemical history in the textbook,and develop the course resources of chemistry history according to the deficiency of chemical history in the textbook,in order to make up for the deficiency of chemical history in the textbook,It also provides the corresponding curriculum resources for students to study chemistry.The research shows that the chemical history involved in the teaching materials is relatively simple,the chemical history of the exercise column appears less,the lack of students ' view of chemical essence and the carrier of chemical values education,so this thesis has developed the Chemistry history curriculum resources from four aspects,in order to make up for the shortcomings in the teaching materials,but also for students to learn chemistry knowledge To meet their unique needs.Therefore,on the basis of analyzing teaching materials and developing the curriculum resources of chemistry history,in order to optimize chemistry teaching,this paper puts forward some suggestions to the writers,chemistry teachers and students of chemical teaching materials.In teaching materials,we should pay more attention to the history of chemistry and the controversy between schools,the body part of teaching materials should pay attention to the presentation of the history of chemistry,and the secondary school teachers should first attach importance to the teaching of chemical history,and secondly,we should enrich their knowledge of chemical history,and give full play to the educational value of chemical history.Allowing students to combine chemical knowledge in class with historical materials of chemical history can help them understand chemical knowledge in essence.
