Research On The Evaluation Of "Acids And Bases" In The Chemistry Textbook Of Three Editions In Junior High School

Since the Ministry of Education issued the "Basic Education Curriculum Reform(Trial)" in 2001,the development of Chinese textbooks have entered the "One Standard,Multiple Versions" era.The "One Standard,Multiple Versions" policy created a new situation of curriculum innovation in China but also led to a number of academicians,experts questioning the curriculum reform,many of which were about the textbook's imperfections.With the "Chemistry Curriculum Standards of Compulsory Education" promulgated in 2011,the development of junior high school chemistry textbook presented a diversified situation.Textbooks complied by the People's Education Press,the Shanghai Education Press,the Shandong Education Press,the Popular Science Press,the Science Press and the Guangdong Education Press have been through the review of the Ministry of Education,and are now on trial in some provinces and cities.The quality and the effect of the five versions of textbooks have increasingly become the focus of the education researchers.In recent years,the number of thesis with the research subject on the evaluation of textbook cross-strait showed an increasing trend,but most of the existing researches stay at the macro level,lacking exploration at the micro level.This paper combines the methods of document analysis,expert consultation method,survey method and fuzzy analytic hierarchy process,constructed the junior high school chemistry textbook evaluation system,Using the content of "acids and bases" as an example,it evaluated the three versions of the junior high school chemistry textbooks.The paper mainly includes the following five parts:The first part is mainly an introduction,including the background and significance of the study,the domestic and foreign research situation,subjects and methods of the study,the research ideas and the thesis structure.The second part is about the theoretical basis.It conducts analysis on some of the basic concepts related to the textbook evaluation in the article,and briefly introduces the theoretical basis for the design and the evaluation of the textbooks.The third part is about the construction of the junior high school chemistry textbook evaluation system.The complete system is built through the investigation on the evaluation indexes,the recognition on the evaluation criteria and the evaluation index weight coefficient.The fourth part is about the evaluation of the content "acids and bases" in three versions of junior high school chemistry textbook.The conclusion is drawn based on the analysis on the characteristics of the specific content as well as the survey results.The fifth part is the conclusion and the enlightenment of the study.The author summarizes the evaluation results on the content "acids and bases" of the three versions of the junior high school chemistry textbook,and puts forward reasonable proposals to the textbook managers,the textbook writers,the chemistry teachers and the future researchers.Finally,the author reviews the study,summarizes the research limitations and makes prospects for future studies.
