| Teaching materials are the concentrated embodiment of educational ideas and education training objectives.The construction of teaching materials not only affects the promotion of elementary education curriculum reform but also deeply relates to the development of socialist cause.Therefore,the CPC Central Committee and the State Council have always attached great importance to the compilation and publication of teaching materials.Since the reform of basic education curriculum in the 21st century,the implementation of the policy of "One outline and multiple textbooks" has made the teaching materials of each subjects present a diversified situation.At present,five sets of high school physics textbooks have been used in the test areas of all over the country.In addition to meeting the consistency requirements of the new curriculum standards,each version of physical textbooks have their own characteristics in aspects of teaching material structure,knowledge presentation and meet the needs of students in different regions Learning needs.Comparing and analyzing different versions of physical teaching materials plays an indispensable role for teachers and students.However,researchers are mostly based on the subjective understanding of teaching materials,which makes most teaching materials analysis mainly qualitative,and lacks the support of quantitative data.Therefore,in order to break through the new way of teaching material analysis,the author decided to use the interpretative structure model(ISM),take the PEP edition and Shanghai Science edition high school physics compulsory 1 Textbook as the research object,and develop a new method based on educational information science,analyze and compare the knowledge structure of the two textbooks,in order to provide useful reference for the arrangement of teaching acti vities.Firstly,the relevant concepts and the operation steps of ISM method were summarized by literature research method.In order to further understand the teachers and students on the use of physics textbooks and evaluation.Part of high school students in Changsha,Taiyuan and three teachers in Wuhan were selected as the investigation objects to carry out interviews and questionnaires.Secondly,discussion on the basic basis of analysis physics teaching materials,using ISM method to analyze two version of the physics teaching materials,establish the hierarchical directed graph of the two editions of the textbooks,and compare the similarities,differences and characteristics of the two versions of physics textbooks from multiple dimensions.The results verify the feasibility of using ISM method in the knowledge structure analysis of physics textbooks is verified.compared with other methods of teaching materials analysis,ISM method is more detailed and comprehensive,which provides a new approach for teaching materials analysis based on educational information analysis technology.Finally,the author gives appropriate suggestions on the compilation of teaching materials,the use and analysis of teaching materials for teachers,reflects on the shortcomings of this study,and look s forward to the research on the application of ISM method in the field of education and teaching. |
