Optimization Of Chemical Experiment Teaching Theory System And The Practice Research In High School Chemistry Teaching

With the development of the society, the new curriculum reform puts forward higher requirements on the chemical experiment teaching, and the chemical experiment teaching theory also needs corresponding increase, which will guide the implementation of the chemical experiment teaching better.Chemical experiment,chemical experimental teaching,chemistry teaching theory, chemical experiment teaching theory,chemistry experiment teaching course system and related concepts are discussed in detailed elaboration in this paper to find out the different and focus. The current people in the subject have certain research about chemical experiment teaching theory, but little research on the system as a whole. The third chapter is the implementation present situation investigation and analysis of chemical experiment teaching theory in the high school chemistry, by means of Anhui Normal University sophomore, junior students’questionnaires, and Anqing, Chizhou in Anhui, Shanghai, Lanzhou, Gansu province, Tianshui city high school chemistry teacher interviews and questionnaires, realized the shortcomings existed in the current chemical experiment teaching theory, such as scientific definition is undefined, absence of subject research object, subject research method is not clear, the subject system of experimental teaching and experimental research method are separate, subject teaching methods are rigescent and there are certain problems in teaching methods and teaching evaluation. Aiming at the shortcomings of the above, analyzed teaching syllabus of the chemical experiment, and analyzed the existed teaching material " chemical experiment teaching theory", giving the optimization of chemical experiment teaching theory system in the teaching idea, teaching content, teaching methods, assessment methods and teaching level.Concept level, achieved the unity of textbook titles, a perfect theory system can provide a scientific and standardized basis, formulate the principle and strategy of optimization; content level, construct a new chemical experiment teaching theory content system, the basic theory article, teachers and students, teaching research papers article and practice design article.The new module system increased the teachers and students, highlights the connection between the subject and the experimental teaching. Optimized concrete experiment content in practice design article, the verification experiment was carried out exploratory design, increased microchemical and half the miniaturization experiment, increased the life fun small experiment, instill the concept of green; teaching method level, according to the different training objectives and teaching content to develop different ways of teaching; teaching practice level, the experiment method, the experimental device for the innovation; evaluation way level, pay great attention to comprehensiveness of evaluation content, the diversity of evaluation method, the rationality of the evaluation category and evaluation of simplification of the operation. In high school chemistry compulsory module, for example, to select some typical experiment using the chemical experiment teachingtheory as cases of specific design analysis, different emphasis on from the performance optimization of experiment contents design methods, retained the metallic iron react with water, in order to train students to the standardization of operation; miniaturization is made for the conventional experiment of charcoal reduction copper oxide and greening design; the traditional verification experiment conducted to explore the design of preparation of nitrobenzene.
