A Study On The Order Of "Chemical Balance" In High School Chemistry Textbook

Over the years, our teaching system is based on "one key link",which is the principle of teaching material redaction under the guidance of the nationally standardized outline or curriculum standards. In particular, some core basic courses(such as Chinese, mathematics,English, etc.) are nationally standardized textbooks. In 2001, the Ministry of Education issued the "Basic Education Curriculum Reform(Trial)"proposing to implement the diversification of Textbook: “under the guidance of national basic requirements we execute the textbooks diversification policy, encourage the relevant agencies, publishing and other organizations to write textbook for primary and secondary schools based on nationally standardized curriculum." Under the guidance of this policy in recent years, different textbooks are coexisting in our market of teaching materials under the regulation of basic education curriculum reform syllabus and curriculum standards specification. In the context of the new curriculum reformation, teaching materials are changing with the new curriculum reformation ideas; the role change of teaching materials has also put forward new requirements for teaching materials; the selection of teaching materials is more than before; a lot of novel ideas on how to write a textbook have been bought into consideration and the formation is more diverse than before. However,teachers as the organizers of teaching activities and the direct users of those teaching materials are still confusing about some of the changes.Although the theory of teaching is more advanced and content is richer, many teachers in the teaching practice feels "not work " and are confused to the change of the sequence in teaching content. Some teachers even abandon the use of materials or rarely use them. Instead, they look for other teaching Information. This does not only increase the workload of teachers and waste the well-developed teaching resources, but also does not ensure that the new concept of curriculum reform to be achieved in practice. In this case, witch compiling sequence can be used in organizing the teaching contents?How can these sequences be used in organizing the teaching contents scientifically and reasonably?And which sequences can promote the overall development of students?Studying the compiling sequence of a certain teaching content in textbook is a necessary measure and basis of solving these problems. In this study, we proposed two aspects which are subject content clues and cognitive processes clues to analyze the “chemical balance” in five sets of domestic high school chemistry textbooks. We attempted to provide references in using textbooks, thus classroom instruction could be organized more effectively and efficiently, and teaching quality could be improved. We also hope to provide some experience and methods for the study of chemistry textbooks written.There are four parts in this study.The first part is chapter one.In this part, the origin of the problem 、 the literature review and the research object and method are in it.The second part is chapter two. In this part, we established our research tool.The third part consists chapter three to chapter seven. There is the research and analysis of the “chemical balance” in five sets of domestic high school chemistry textbooks.The forth part is chapter eight. On the basis of the above analysis, it summarized the similarities and differences of the compiling sequence in "chemical balance", and it provided its own little humble opinion for the preparation of textbooks.
