Analysis On The Content Development Of Chemistry History Of High School Chemistry Textbooks In China In The Past 40 Years Of Reform And Opening-up

In 1952,the Ministry of Education issued the "Provisional Regulations for Secondary Schools(Draft)" for the first time that the educational goal of secondary schools was to cultivate "double bases";in 1999,the "Decision on Basic Education Reform of the State Council" proposed "three-dimensional goals";The "General High School Chemistry Curriculum Standards(2017 Edition)" promulgated by the Ministry of Education proposes to develop students’ core literacy.Whether it is "double base","three-dimensional goal" or "core literacy",chemical history can serve as a good carrier,because the history of chemistry contains a wealth of chemical knowledge,including the process of scientific thinking,students can not only from chemistry The family learns the methods of chemical research in the process of exploring chemical knowledge,and can learn and inherit the unique scientific attitude and scientific spirit of chemists.It can be seen that the content of chemical history is a valuable resource for chemistry learning and an important way to develop students’ core literacy.Textbooks are the carrier of teaching and learning and play a pivotal role in chemistry teaching.What is the evolution and evolution of the history of chemical history in China’s high school chemistry textbooks during the 40 years of reform and opening up?In order to better understand the development of chemical history content in textbooks,this paper selects the contents of chemical history in several sets of chemistry textbooks that have been representative since the reform and opening up,from the content selection,presentation methods,and the organization of chemical history content.Several dimensions such as learning methods were compared and analyzed in order to find out the development trend and trajectory of the history of chemical history,and to draw conclusions and enlightenment from it.I hope to provide some reference for the preparation of the new textbook chemical history content,and help frontline teachers and educators understand the concept of the new curriculum standards,attracting the importance of the history of chemistry,and giving full play to the importance of chemistry history in chemistry teaching and learning.effect.This article is divided into six parts:The first part is the introduction.The background and significance of the topic,the purpose and method of the research are expounded,and the research ideas of thispaper are clarified.The second part is a review of research at home and abroad.On the basis of consulting a large number of documents,it summarizes the research status of textbooks and chemical history in China and abroad.The third part is the theoretical basis of concept definition and research.The concept definition of chemistry textbook,chemistry history and chemistry history education is defined,the theoretical basis of this research is clarified,and the framework of content analysis of chemistry history is constructed.The fourth part is a comparative analysis of the contents of the chemical history of high school chemistry textbooks,which is the key part of this paper.Firstly,the development trajectory of high school chemistry textbooks in China is clarified,and then a detailed comparative analysis is made on several dimensions such as the overall quantity distribution,content selection,presentation mode and learning style of chemical history in textbooks.The fifth part is the conclusion of the study.Based on a comprehensive analysis of the contents of chemical history in textbooks,the results are compared and the reasons for changes in the history of chemical history are analyzed.The sixth part is the revelation.According to the research conclusions,some suggestions are put forward for the preparation of chemistry textbooks and the teaching of chemistry history.
