Development And Application Of Chemistry Interesting Experiments In Middle School

The purpose of chemistry education is to stimulate the curiosity of students to learn chemistry,guide students to understand changing rules of the material world and form the basic concept of chemistry.The chemistry experiment is an important way to inspire students ’scientific thinking,cultivate ones practical skills,guide students to understand the relationship between chemistry,technology,society and environment,and improve students’ scientific literacy.Interesting chemistry experiment can stimulate students ’interest in learning and desire for seeking rather than teach chemistry knowledge vividly,and can active classroom atmosphere effectively,overcome teaching difficulties,inspire students’ thinking,and ultimately achieves the purpose of cultivating students’ love and pursuit to science,promoting Scientific literacy,improving self-cultivation.Based on the theory of constructivist learning,theory of meaningful learning and theory of "doing middle school",this study follows the principles of safety,simple feasibility and lifelization of interesting experiment development,and makes use of a variety of ways to collect material from the two aspects of chemistry teaching,daily life and develope series of interesting chemical experiments.Ways including the color change in the chemical reaction,the change of material state,experimental device Improvement,the "magic" elements adding,etc.;We obtained the best experimental conditions through a large number of experimental exploration.To facilitate the use of students and teachers,high-quality teaching resources were settled finally by combining words images and video to show the development of the experiment clearly.This study is used in practice teaching class and teacher application in two ways to apply.In the teaching class using of fun experimental video or fun experiments to teach,students were interested in the chemistry has been significantly improved.In the city of secondary school chemistry teachers teaching and research activities and the "National Peking Program(2016)" national teacher training project to promote the classroom atmosphere becomes more active,students have a positive attitude to answer questions.The experimental research shows that interesting chemistry experiments have apositive effect on improving students’ interests in learning,activing classroom atmosphere,and enhancing students’ love and pursuit of science.This study will continue to enrich and perfect the interesting chemistry experiment.Furtherly,the research results will be summarized and promoted by the ways of monographs,CDs.
