A Comparative Study Of The Old And New Textbooks Of Lu Ke's "Principles Of Chemical Reaction"

In 2013,the Ministry of Education initiated the revision of the high school curriculum.On the basis of summing up and absorbing the experience of past curriculum reform and learning from the outstanding achievements of international chemistry curriculum reform,the high school chemistry curriculum system with Chinese characteristics and reflecting the requirements of the times has gradually been built.As the first optional module,the "Principles of Chemical Reaction" carries the important task of implementing the new curriculum concept,and simultaneously plays a vital role in cultivating and improving students' core literacy.The Luke version of the "Chemical Reaction Principles" textbook has been published in 2019 and put into use in 2020.In order to help front-line teachers better understand the changes in the textbook under the guidance of new curriculum standards,and then better carry out the curriculum practice based on the core literacy of chemistry,this study chooses the textbook analysis model to conduct a static analysis of corresponding textbooks.On the basis abovementioned,a questionnaire survey and interview research were conducted among senior high school chemistry teachers in various regions of Qingdao city.This dissertation is composed of five parts,the specific content is as follows:The first part introduces the background of the new curriculum reform,reasons and significance of choosing the textbooks of " Chemical Reaction Principles ".It summarizes the current situation of the comparison of textbooks and introduces the research ideas and methods.In part 2,the basis for compiling the two editions of textbooks,"Curriculum Standards(Experiment)" and "Curriculum Standards(2017 Edition)",is compared to clarify the changes in curriculum standards.In part 3,comparative analysis for the two editions of textbooks is conducted from the perspective of content organization,content selection,and content presentation according to the selected model.The content organization is mainly to compare and analyze the layout system of each chapter of the two editions of textbooks.The content selection concentrates on analyzing the addition,modification and deletion of the selected textbooks.The content presentation focuses on the comparison of columns,illustrations and exercises of corresponding textbooks.Through the in-depth comparison and analysis of the text,the similarities and differences between the two editions of textbook,together with the characteristics of the new textbook,are explored.In part 4,questionnaire surveys and interviews with senior high school chemistry teachers in various regions of Qingdao city are conducted to understand the opinion and usage of the two editions of textbooks by frontline teachers,and draw the comparison results of the two editions from the practical level.In part 5,the texts of comparative analysis and the results of investigation and research were summarized and corresponding teaching suggestions on the use of the new version of textbook were provided,hoping to provide some references for teachers' teaching design and practice.The research shows that the revised textbooks,on the basis of inheriting and carrying forward the characteristics of the old textbooks,further highlight the new characteristics of core literacy orientation,and explain the connotation and development of the core literacy of chemistry from a high point of view,a large field of vision,a multi-angle,and a layered interpretation.The characteristics of the new textbook are specifically manifested in five aspects:(1)The new textbook keeps pace with the times,highlights new ideas and new content,and attaches more attention to the connection between chemistry and social life.(2)The new textbook attaches importance to the stages and continuity of knowledge development,and optimizes the arrangement of some knowledge.(3)The new textbook refines core experience,creates activities and experimental advancements,and highlights that chemistry is a characteristic of experimental science.(4)The new textbook creates "micro-projects" to develop students' core literacy and realizes the integration of "teaching,learning,and evaluation".(5)The new textbook is equipped with more diverse columns,illustrations,and exercises to better meet the development needs of students.
