Different Versions Of Comparative Study Of High School Chemistry Compulsory Teaching Material "Element Compounds"

With the start of the reform of basic education curriculum,The new changes have been made accordingly.Textbook is no longer in the pursuit of "multi-edition with a common aim" but "one series of textbooks under the same syllabus".At the same time,the content of "Element compounds" is the basis of other chemical knowledge. If of this part of the knowledge is not strong mastered, Students will seriously affect the subsequent learning of knowledge.So this paper comparative analysis of the content about “Element compounds” in the three sets of high school chemistry teaching material.This has a positive significance for teachers to better understand and grasp the teaching materials, as well as the more effective teaching of “elements compound”.This paper started from the curriculum standard, analyses and compares the current three versions of the compulsory "element compound" part. These three versions the three sets of high school chemistry compulsory(2012 revision) new materials. This paper adopts literature method, text analysis method, comparative research method, and summarizes the general idea of the analysis of the teaching material,and analyses the consistency of teaching material contents and curriculum standard,the content arrangement system,and content presentation mode according to this idea.The specific analysis is as follows:In terms of content selection,the teaching material first analyses specifically the requirements of the curriculum standards, and then analyses the consistency of the curriculum standards and textbooks elements in some compounds.Further specific knowledge of the various elements were selected for analysis, to obtains the version knowledge point selection characteristics.In the content organization, the paper first analyzes the overall preparation of the teaching materials, and the three versions of the "element compound" part of the layout characteristics were compared;And then analyzes the various versions of the "elements" of the specific elements of the arrangement of ideas, the characteristics of each version.In terms of content presentation,This paper contrast analyses the three versions in the "element compound" part of the similarities and differences from three angles—the column design, experiment, and picture.Finally, the author gets their respective characteristics of three versions of the "element compound" through a series of comparative analysis,and gives suggestions for teaching textbooks.
