Empirical Study On Operating System In High School Chemistry Textbook Changes In The Composition Of Features And New Materials Operating Capacity

Abstract:Chemistry operations is an important part of high school chemistry textbooks, but also an important guarantee for high school students to learn chemistry. It is not only charged with the task of basic knowledge of chemistry to help students to consolidate classroom learning, is also charged with the important mission to cultivate students’ability to innovate, improve students’scientific literacy. China’s new round of curriculum reform focused on improving the scientific literacy of the citizens in the21st century to enable students to form a scientific world outlook, cultivating students’ innovative spirit and practical ability to achieve the purpose of the overall development of students. New curriculum reform requires the preparation of chemical exercises should be diversified, to increase the proportion of practice questions and open problems, and must also help students identify problems and ask questions by students on the integrated use of knowledge to solve practical problems.Since the1980s, with the high school chemistry textbook changes, the operating system has also undergone some changes, and in the operating philosophy, the number of jobs, job forms and job columns. The topics selected typical chemical materials for years in China since the1980s, specifically:the senior high school textbook published in1983, the next book, published in1995the first volume of the senior high school textbooks, Volume II, Volume III, published in2000full-time ordinary senior high school textbooks of compulsory and elective materials, the latest round of curriculum reform is to use the People’s Education Press, Shandong Science and Technology Press, Jiangsu Education Press published three textbooks. Statistics the number of job total number of old and new textbooks, the average number of exercises in each section, all kinds of questions proportion, use data analysis software for analysis of statistical data and obtained the characteristics of the changes on the job number and kinds of questions of the old and new textbooks, analysis of old and new teaching materials job showing some of the differences in the way, summed up the characteristics of the new textbooks for the training of the students’ thinking abilities, concluded that the characteristics of the operating capacity of the new materials. Five modules in accordance with the chemistry of chemical concepts, the classification of the theory of chemical elements and compounds, organic chemistry and experimental chemistry of each module, the knowledge of related operations into the statistics, combined with the knowledge of learning characteristics and new curriculum knowledge of learning requirements, analysis of the operating capacity of the three kinds of teaching materials, and operating capacity to the wrong place to make a reasonable proposal, and select the two instances of the appropriate operating capacity model. Reasonable, with a workable proposal for the design of the operating capacity of high school chemistry textbooks for reference, but also for the majority of high school teachers and students in teaching and learning, better use of chemical materials operations.
