The Optimization Tactics Of The High School Chemistry Demonstration Experiment Teaching Research

High school chemistry demonstration experiment is an important part of high school chemistry teaching, and from it is concluded that the knowledge of chemistry in chemistry teaching is an important method and means.Therefore decided the important position of chemistry demonstration experiment in chemistry teaching and the role.A good demonstration experiments can fully arouse the students’ interest in learning chemistry knowledge, help students to understand the chemical concepts and principles of boring to understand, to cultivate the students’ ability of observation and thinking.So, in the high school chemistry teaching, the status of the chemical experimental demonstration to be reckoned with.Due to the demonstration experiment is so important, but in actual teaching, the chemical experiment teaching demonstration has shortcomings, therefore, the author combined with previous studies and according to the characteristics of chemistry demonstration experiment and the actual teaching situation, under the guidance of "the high school chemistry curriculum standard", choose the high school chemistry demonstration experiment teaching present situation investigation and optimization strategy for research.This thesis consists of five parts.The first part:introduction, mainly including high school chemical experiment teaching demonstration and optimization strategy research background, research content, thinking method and current research situation at home and abroad about chemistry demonstration experiment.The second part:the basic theory of high school chemistry experiment teaching demonstration, mainly explains the definition, classification, function of chemistry demonstration experiment teaching, and should follow the teaching principles and the theoretical basis of demonstration experiment teaching.The third part:the establishment of the present situation of the current high school chemical experiment teaching demonstration questionnaire, recycling questionnaire and statistical analysis was carried out on the collection of data, it is concluded that the current status of high school chemistry experiment teaching demonstration:(1) High school chemistry teachers in the contradiction between the idea and practice demonstration experiment teaching.(2) The pursuit of simple graduation rates and ignore the learning ability of the students and the improvement of ability.(3) In practical teaching of high school chemistry teachers did not often present in the classroom demonstration experiment.Ready to relatively is also not very good.(4) Less attention to students through reflections on the core concepts of the demonstration experiment.(5) High school chemistry teachers to demonstrate initiative of improving poor effect of experiment is lower.(6) The demonstration experiment curriculum resource utilization in high school chemistry teachers still stay on the level of teaching materials.(7) High school chemistry teachers in chemistry knowledge and contact aspect of life is not enough attention.The fourth part:through the analysis of the data of questionnaire investigation, put forward the optimization tactics of the high school chemistry experiment teaching demonstration:(1) Improving teaching method, reform the traditional teaching mode.(2) Increase the students’ experiment, improve students’ learning interest.(3) Improve the experiment ability, optimize the teaching effect.(4) To improve the teaching method, improve the multimedia auxiliary teaching.(5) To improve the experiment teaching AIDS, optimizing experimental teaching effect.(6) To optimize the design of experiment, improve students’ learning interest.(7) Pay attention to the experimental results, master the necessary life skills.The fifth part:conclusion, mainly expounds the summary and deficiency of this study.Hope this article through research of the related conclusion can cause the attention of teachers, more deeply aware of the importance of chemistry demonstration experiment of teaching, actively explore optimization demonstration experiment, make it play a greater effectiveness, and promote students’ learning, the maximum in order to improve teaching efficiency.
