Comparative Study Of The Two Chemical Materials In China And The United States On The Mystery Of The Material Composition

Teaching material as the subject of knowledge and skills system, not only embodies the nature and development of the discipline, and embodies the specific form of the course, embodies the content of learning, plays an important role.Now development level of teaching material is relatively low in our country, So it is necessary for foreign interdisciplinary study compared the excellent teaching material, teaching will help China’s chemical and reform the precious experiences we should adopt.This paper use research methods such as comparative research, case comparison method and literature method in “the mystery of the material composition”, for example contrast the Chinese version of junior middle school chemistry teaching and <the scientific explorer?Chemical reaction >(mainstream American junior high school science teaching material of the third edition).Through to the United States and the junior middle school chemistry teaching material analysis and comparison, find out the chemical teaching material in the architecture, the choice of content, the depth of the content, the content of presentation of similarities and differences, analyzing both the advantages and disadvantages of the chemical teaching material and the characteristic. By analyzing and summarizing <the scientific explorer?Chemical reaction>(mainstream American junior high school science teaching material of the third edition)advantages and characteristics, provides some revelations for Chinese junior high school chemistry textbook. This thesis is composed of five parts:The first part mainly elaborated the research background of this paper and selected topic reason, research methods and research contents, research status and research significance. The second part to the United States and the middle school chemistry teaching material “the mystery of the material composition”, mainly from the mystery of the material of the structure, content choice and adopted by the organization and it show the way of comparison, find out the same and the difference between, and through analysis and comparison of two the advantages and disadvantages of the teaching material, this is a key part of this thesis. The third part is through the comparative analysis summarizes the two in front of the chemistry teaching materials of their respective writing features. The fourth part is the conclusion part of the paper is to compare the content of above conclusion and enlightenment, through the analysis and summary finally concluded similarities between two of the textbook and different writing features, and then lists some Revelations of the junior middle school chemistry teaching material write to our country.
