Comparison Study Of "structure And Properties Of Substances" In Three Versions Of Textbooks

Based on the chemistry curriculum standards, the new chemical curriculum textbooks is the specification of the new curriculum, and primary curriculum resources for teachers and students. "Structure and properties of substances" is a high school chemistry major elective module, and " chemical bond and properties of substances," "intermolecular force and properties of substances " knowledge of these two areas is the course foundation and core subjects content of this module. However, this module in the actual teaching of elective courses encountered difficulties and cold, had caused our focus and thinking before carrying out new curriculum. Based on the present situation and problems, we chose "chemical bond and properties of substances," "intermolecular force and properties of substances" these two themes of the "Structure and properties of substances" module to compare three versions(Renjiao version,Sujiao version,Shandong version) of high school curriculum standards test textbook.Hope to provide useful help to the choice and teaching of the textbook in the implement of the new high school curriculum standards textbook.Under the guidance of Structure theory of the teaching materials, textbooks System "three sequence" of the Combination, textbook evaluation criteria such as the theory of a selection of textbooks, as well as meaningful learning and Constructivism learning theory, we initial build out the framework of textbook Analysis; to Content Analysis guidance for the methodology of comparative analysis of patterns and establish the theme and content of the analysis model into analysis of specific categories. Related operation is static and dynamic study of the method of combining, and based on high school chemistry curriculum standards, the content of the three versions of the textbook selection and arrangement, content, organization and presentation of the design and preparation of exercise three dimensions, the static analysis and comparison, combined with the dynamic study was a survey and interviews, to explore the arrangement of the various versions of the textbook features and advantages and disadvantages, proposed advices of use of the textbooks.Static study of the textbook, begin with the study of convergence of the two themes and compulsory modules. Comparison of content selection and arrangements involving the new knowledge content, the chapter layout, and the activities and inquiry in the three versions of textbooks. Quantitative and qualitative comparison of the content organization and presentation related to function and type of the columns and charts. Comparison of exercise of textbooks discussed the classification of types and related characteristics.To further understand the "Structure and properties of substances" module in the actual teaching and learning situation of the two themeswe investigate the curriculum reform area to do dynamic studies.Used self'-design questionnaire to survey,combined with interviews of teachers and students to find the results.We found that there are common characteristics about the arrangement of the three versions of textbooks:â‘ The content consistent with the requirements of course standard point , and highly academic, theory difficult; Added a number of important concepts in academic theory and extends the practical application of the theory, making both the academic and the Times.â‘¡Two themes had been integration in the structural, that means lay the main line which unite to arrangements microstructure and macroscopic properties,and combining the abstract theory and modeling method.â‘¢There are a variety of organizations forms to reflect the construction of activities of the textbook.,which including the multifarious of columns and graphics material, especially the thinking and discuss columns.â‘£The model-oriented method is applied to theory construction.Common features from the textbook, combined with the investigation, and puts forward the general recommendations of teaching:â‘ Good linking up teaching course content with other modules, practical grasp the depth and breadth of teaching content.â‘¡Make full use of modeling approach, combining macro and micro explanations abstract theory.â‘¢Full use of the textbook variety of columns and material build learning ladder diagrams.â‘£Closely around the interaction between particles and interpreting the relationship between structure and properties of substances.According to the advantages and disadvantages of different versions of textbooks proposed advices of using of the textbooks.â‘ Renjiao version textbook focuses on practical and Reading, and thinking types of activities, charts are relatively rich and comprehensive ,and provice adequate practical Questions for after school study. In the teaching we should made good use of activity and comprehensive chart resources, and make up relevant knowledge of the required course module. Supplement the lack of exercise about some knowledge point, and to increase training of the contextualization of. problem solving.â‘¡Sujiao version textbook: the theory of structure and the applications of properties used simultaneously, learning activities focus on discussing and thinking types of activities. Using the textbook should make full use of their knowledge convergence compact, optimized combination of different sections, textbook exercises at different levels of advantage, increase the innovative exercises and hands-on practice-type exercises, the phenomena in the experiment plan to do additional supporting material.â‘¢Shandong version textbooks written focus on expanding the theoretical depth and the application breadth, thinking and reading activities, focus on the learning guidelines. When teaching we need to exert functions of guiding learning methods about the method section and evaluation of praxis, use information section to expand theory, and can added appropriatly the chemical history of theoretical development to promote understanding and learning.
