Comparative Study On The New And Old Compulsory Textbooks Of High School Chemistry ——Take Compulsory Volume 1 And Compulsory 1 As An Example

With the development of economy and society,students' environment has changed,students' cognition and growth needs as well as the social requirements for the educates have all changed.Recognizing this change,the national education policy has also changed for the talent training of the new era,and put forward the educational purpose of "establishing virtue and cultivating people".Therefore,the new curriculum reform arises at the historic moment,and the teaching material changes accordingly.Teaching materials are the most basic reference materials for classroom teaching and the embodiment of the core content of curriculum standards.The change of teaching materials contains the change of educational ideas and teaching methods,so the research on the change characteristics of new teaching materials has a certain practical significance and theoretical value.Therefore,the 2007 edition of Required High School Chemistry 1 and 2019 edition of Required High School Chemistry(Volume 1)are taken as the research object to compare them,analyze the characteristics of changes in the new teaching materials,and put forward teaching suggestions according to the characteristics of changes.Specifically,it includes the following four parts:The first part is the introduction,which introduces the research background,research purpose and significance,research tasks and research ideas and methods.The second part is chapter one and two.Through literature research,this paper summarizes the comparative research status of high school chemistry textbooks and analyzes the connotation of Bruner's structure theory,Gagne's classification of learning results and Constructivism theory to pave the way for the construction of textbook comparison framework.Define core literacy,chemistry discipline core literacy,high school chemistry textbooks,textbook comparison.The third part is the third chapter,based on the existing research and literature to build a framework for the comparison of textbooks,from the new and old curriculum standards,overall content arrangement and selection,situational materials and exercises four aspects of the comparison,analysis of the differences to obtain the characteristics of the change of new textbooks.The fourth part,the fourth chapter,compares the results of teaching materials and puts forward teaching suggestions.The overall content arrangement of the new textbook reduces the learning difficulty and knowledge structure,which accords with the law of students' cognitive development.The number of material related to science and technology,life and chemical history of the situation material has increased significantly,and the material is more contemporary.Exercises less quality increase,increase the new questions,experimental questions accounted for the largest increase,flow chart questions and industrial production linked,exercises contained in the real situation,increased the actual situation from production,life,highlighting students' thinking,information processing ability and literacy examination.According to the conclusion,some suggestions are put forward in order to enlighten and help teachers' teaching.The suggestions are as follows: 1.Emphasize the links in the teaching content structure.2,emphasize the use of situational materials to introduce new knowledge.3,effective development and utilization of resources.4.Focus on classical experiments and industrial processes.5,improve the awareness of research learning.To the operation reform to quality.7.Change the classroom model.
