Comparison And Analysis Of Textbooks Of High School Chemistry Compulsory 1 Based On ISM

So far,the new high school curriculum reform has been implemented over the past decade.Textbooks are the bearer of curriculum objectives and educational philosophy,whether the quality of the content of teaching materials is high or not,whether the arrangement of the order of teaching materials fits the development of cognitive laws of students or not,whether the structure of teaching materials system is perfect or not,all of these are related to the success or failure of curriculum reform.To solve the above problems,Interpretive Structural Model(ISM)was introduced,which is applied to the comparison and analysis of Chemistry Compulsory 1 textbooks.Firstly,the current situation of application of ISM in comparison and analysis of textbooks was investigated,the existing literature research areas were combed,the existing problems had been emergied and the cut-in point of the paper was found.Secondly,the questionnaire and interviews were used to investigate the teachers' and students' perception of the content of the "elements and their compounds" in high school Chemistry as well as the use of Chemistry textbooks in high schools.Specifically using the ISM to make a comparison and analysis on the actual presentation order of the content of textbooks about the "elements and their compounds" of the version of People's Education Press(PEP)Chemistry textbook and the version of Jiangsu Education Press(JEP)Chemistry textbook that provides a brand perspective for comparison and analysis of teaching materials.Thirdly,based on the ISM,a digraph of factor level about the"elements and their compounds" of the version of PEP Chemistry textbook and the version of JEP Chemistry textbook was constructed,and their respective characteristics in the order of arrangement was discussed.Finally,based on the ISM,the analysis results of the textbooks forming the digraph of factor level,which attempts to provide the innovation of teaching as well as the guidance of learning methods.The results show that:Based on the ISM,a digraph of factor level can be constructed,which provides a new perspective for the comparison and analysis of textbooks.To promote the innovation of teaching,with the help of digraph of factor level,teachers can design a reasonable lesson plans and also improve the teaching effectiveness.And to promote the guidance of learning methods,it explores a scientific and rational guidance model.
