Current Situation Of Secondary Development Of Ninth-grade Chemistry Textbook For People's Education Edition

Textbook plays a very important role in the implementation of curriculum,and it is the key content for teachers to carry out teaching activities and organize students' learning activities.However,in the former teaching concept,the teaching material has the absolute authority position,the teacher's teaching activity completely revolves around the teaching material and unfolds,is the teaching material "imitators".This kind of teaching is monotonous,boring and not innovative.At the same time,with the rapid development of information technology,access to knowledge has become diversified,"teaching materials" teaching method has been unable to meet the requirements of The Times.Therefore,the secondary development of textbooks is the development trend of the new curriculum reform.Textbooks of secondary development is in a development on the basis of the subject in curriculum implementation,teachers and students on the basis of system science method,content of teaching materials properly add,delete,modify,replace and change the content sequence,and the related teaching materials integrate reasonably,to reach the desired operational process of the teaching goal.This paper analyzes the research status of the secondary development of textbooks and finds that most of these researches are theoretical researches and empirical researches on textbooks in different stages of different disciplines.Even the research on the secondary development of chemistry textbooks is mainly focused on high school textbooks,and there are few empirical studies on the secondary development of chemistry textbooks for the 9th grade in PEP junior high school.Therefore,in view of this situation,this paper takes some junior high schools in Nanning,Guangxi as examples to investigate and study the current situation of the secondary development of chemistry textbooks for the 9th grade in PEP junior high school.On the basis of the analysis of questionnaires and cases,combined with the teaching experience of myself and other teachers,it is found that the main problems of teachers are that they do not study curriculum standards deeply enough,are subjected to examination-oriented education deeply,ignore students' subjectivity in the secondary development,and lack scientific and relevant guidance.When there are major problems in students' learning,they are too dependent on teachers and lack the consciousness of autonomous learning.The backwardness of school hardware facilities and the lack of relevant funds also increase the resistance factors to the secondary development of textbooks.In order to promote the effective implementation of the teaching material of secondary development,the need to teaching material's secondary development current situation of the implementation of a comprehensive range of the overall analysis,from the establishment of teaching material is the basis of secondary development requirements to the research and analysis of the relevant factors of teaching to the selection of the design of teaching aims and teaching methods,then the effect of secondary development of teaching material of summary and reflection,and finally elaborates the developing environment of security to the teaching material,for the ninth grade chemistry teachers to provide practical guidance.This paper is divided into six parts: The first part describes the reasons for the topic,research significance,research ideas,research methods and theoretical basis;The second part is the literature review,which mainly analyzes and summarizes the theories and current situation of the secondary development of textbooks at home and abroad,and points out the deficiencies in the research,to determine the research direction of this paper.The third part is the investigation and case study.The investigation and research are mainly analyzed from two aspects: One is to investigate the current situation of teachers' secondary development of teaching materials and the resistance factors encountered;The second is to investigate and analyze the current situation of the secondary development of textbooks and students' learning needs from the perspective of students.The case analysis is mainly based on the research and analysis of the specific development results of the secondary development of teaching materials by the chemistry teachers themselves and others,from which the existing problems are found.The fourth part mainly analyzes and summarizes the problems existing in the implementation of the secondary development of teaching materials,and puts forward feasible Suggestions for the basis of the following;The fifth part is based on the existing problems in the investigation and cases,combining with the author's teaching experience as a first-line chemistry teacher and other chemistry teachers' teaching cases,to provide relatively perfect Suggestions;The sixth part is the summary and reflection,which mainly summarizes the current situation of the secondary development of textbooks in Nanning,Guangxi,and reflects on the shortcomings of this paper.
