The Research Of Tetra-Representation Teaching Model On Chemistry Concept In High School

Multiple Representation theory is applied to the concept of teaching theory, the theory of multiple representations focus and integrate the chemical concept teaching has been studied. On the basis of the theory of multiple representations, Professor Yang Yi Qian made quadruple characterization teaching mode, designed to guide students to promote understanding of chemical concepts in essence, the nature of the reaction and experimental works. In this paper, after the three versions of the system and the concept of high school chemistry concept formation process is analyzed, discussed the concept of multiple representations in the concept formation process of the value determined can be characterized three concepts quadruple group.Professor Yang Yi Qian quadruple teaching mode characterized as the prototype for the lack of description of the specific teaching of thinking and ignore the development path of two problems that exist in prototype mode, the model was amended to incorporate the build-centered thinking 5S sub-mode and deductive thinking centered 5D sub-pattern to provide a desired reference and inspiration for the chemical concept teaching.The thesis is divided into five parts:Part I:Overview of research. Of the research background, significance, research content and methods are outlined study chemistry concept teaching strategies and quadruple chemical characterization of the current mode of review, and the text of the core concepts were defined.Part II:high school chemistry concept of ontological analysis. The concept of system characteristics of high school chemistry textbook three versions were analyzed to explore the concept of multiple representations of concepts in the process of formation of the value determined can be characterized three concepts quadruple group.Part III:teaching model based on quadruple characterized Construction. Professor Yang Yi Qian on the proposed four-fold characterization of prototype teaching mode memory problem is corrected in order to build inductive thinking centered 5S sub-mode and deductive thinking centered 5D sub mode.Part â…£:Design and Application of the teaching model based quadruple characterization of the case. Using 5S and 5D sub-sub-mode mode "electrolyte" and "ion reaction" instructional design concept, the design of the case applied to the teaching practice and teaching model were evaluated.Part V:Conclusions and reflection. Summarizing the results of the study, the lack of research present during reflection.
