Study On The Teaching Practice Of Constructing Basic Chemistry Concepts

The basic chemistry concepts is the essence of chemistry. In the high school compulsory teaching practice, pay attention to the construction of students' basic chemistry concepts, to train students' chemical thinking, improve students' scientific literacy have a profound influence. By referring to the existing literature on the basic chemistry concepts, developping on the theme of constructing students' basic chemistry concepts, selecting "Chemistry 1" (Shandong Scientific Press) as a blueprint, making a profound research on the study value of basic chemistry concepts, putting forward some aspects of constructing students' basic chemistry concepts, such as teaching principles, teaching strategies, teaching analysis, etc. Through the teaching practice to evaluate the effect of research. This thesis includes nine parts. The main contents are as follows:The first part, Question put forward. The importance of constructing the basic chemistry concepts in the teaching of "Chemistry 1".I explain the purpose and task of researching on this research.The second part, Journals reviewed. Consult about the research results of basic chemistry concepts at home and abroad, learn the essence, looking for areas of future research, clear the research direction.The third part, The theoretical basis of the research.Part IV, Teaching analysis of constructing the basic chemistry concepts.The teaching principles and teaching strategies of constructing the basic chemistry concepts.In the principle of concept for the teaching goal, overall planning, step by step, perseverance, teach by strategies such as the creation of scenarios, setting problem, clever use of analogy, strengthening the thinking in images, structured knowledge, with experiment, using four characterization, pay attention to the reflection.Part V, comprehensively analyze the modules of "Chemistry 1"in the aspects of curriculum standard and textbook.Part VI, the practice of research. In"oxidizing and reducing agent", "sulfur conversion " for the case of the concept of constructivism teaching material analysis, provide teaching record. Finally, the end of the module test, case interviews, the practice of the report as a reference, analysis and comparison of experimental classes and control classes, to find the theoretical basis for the study of the facts.Part VII, the problems and prospects of the study.This paper has two innovations:First, the teaching principle and the analysis of the basic chemistry concepts are clear, which provide theoretical support for classroom teaching. Second, based on the "Chemistry 1" module to carry out the construction of the basic chemistry concepts teaching research, and through the teaching effect to test the feasibility and operability of the existing research results.
