Study Of The Functions And Application Strategies Of Analogy Image In Chemistry Textbooks Of Senior High School

Analogy image is an indispensable form to convey information in senior high school chemistry textbooks. It is not only an intuitional and vivid image, but also an effective tool for knowledge migration. It is a unity of analogical thinking and image intelligence. Documents analysis、comparison analysis、statistic analysis and case study are adopted in this thesis to introduce the present research situation the inner structure、 characteristic、function and teaching strategies of analogy image. This survey is set to excavate the educational value of analogy image, provide teaching cases for teachers who intend to promote analogical teaching. Apart from the above, this study can be reference material for further research in the theory and practice of analogy image.This thesis is mainly made up of the following six parts:The first part is the introduction of the reason of choosing this topic, present research situation at home and abroad, and the purpose, significance, details and method of the study. The first part points out the direction of this survey.The second part firstly focuses on the instruction of analogical thinking theory basis from the angle of logic and psychology; then it discusses the characteristics and educational value of images in pedagogic context, presents the educational confusion which is brought about by images.The third part stats the inner structure and explaining sentences of analogy images in senior high school chemistry textbooks published by People’s Education Press. After the analysis of the statistics, the characteristics of the analogy image stand out. The analogy images are used properly; the analogical objects mainly come from daily life; the analogical traits are recognized; the types of the images are diversified; the background of images is colorized; and the texts and images are paid equal importance to. Analogy image is the research object in this survey. Better understanding of the object can lay a solid foundation for the follow-up research task.The fourth part introduces the epistemological、methodological、didactics and aesthetic function of analogy images. These are the core content of this thesis.The fifth part gives a brief introduction of the distinction and types of teaching strategies, mentions the TWA and FAR strategies for analogical teaching and then chooses energy changes in chemical reactions classification of material Hess law electro negativity and chirality as typical examples to design teaching plans on the basis of FAR. Analogy image teaching strategies is another core content of this thesis.The sixth part is conclusion and prospect. It overviews the study of this thesis, and the limitations of the study are pointed out. At last, it looks into the development of the functions of analogy images and the prospect of analogical image teaching.
