In The New Old Version High School Chemistry Teaching Material The Element Compound Knowledge's Comparison Studies

Textbook is what teachers and students can feel directly. It is a specific form through which curriculum objectives can be realized. Based on the elements and compounds of senior high school chemistry textbooks, the old and new textbooks are studied thoroughly. With previous experience and theory and combining with the aim of the present study, a vertical and horizontal comparison between the new and old textbook is made using literature method, textbook analytic method, statistics, comparative research, case analysis and other methods.Under the background of the new curriculum, this study has certain practical significance and important reference value for chemistry teachers who can learn to change from"teaching textbooks"to"teaching using textbooks". We try to understand the essential difference between the old and new curriculum by comparing target dimensions, content dimension and resources dimension of the element and compound knowledge of the textbooks. We suggest that a new element and compound knowledge system should be reconstructed based on the new textbooks. The material selection, structure system, writing ideas and the way to present the above things of the elements and compounds of the three textbooks were analyzed. Combining the analysis of some cases, this paper puts forward some reasonable advice to use the new textbooks.
