中學(xué)化學(xué)趣味實驗的開發(fā)及應(yīng)用研究
[Abstract]:The purpose of chemistry education is to arouse students' curiosity in learning chemistry and to guide students to understand the changing law of the material world and form the basic concept of chemistry. Chemistry experiment is an important way to enlighten students' scientific thinking, cultivate practical ability, guide students to understand the relationship between chemistry and technology, society and environment, and improve scientific literacy. Interesting chemistry experiments can teach chemistry knowledge through lively and interesting experiments, stimulate students' interest and desire to learn more effectively, activate classroom atmosphere, overcome teaching difficulties, and inspire students' thinking. Finally, the purpose of cultivating students' love and pursuit of science, improving scientific literacy and individual practice is achieved. This study is based on constructivism learning theory, meaningful learning theory, "doing learning" theory, and follows the principles of scientific, safety, simplicity, life, etc., and makes use of the color change in chemical reaction. The series of interesting chemical experiments have been developed from the aspects of chemistry teaching and daily life by means of changing the material state, improving the experimental device, adding the "magic" element, and obtaining the best conditions of the experiment through a large number of experiments. The experiment is presented clearly by the combination of text, picture and video. It is spread and popularized online and offline, which is convenient for students and teachers to watch and use. Finally, the high-quality teaching resources are generated. This research adopts the practice in the practice teaching class and the peer teacher practice two ways carries on the application research. In the teaching class, students' interest in chemistry has been obviously enhanced by playing video of interesting experiments or by means of interesting experiments. The teaching and research activities of chemistry teachers in middle schools in this city and the National teacher training Program (2016) have been popularized, and the classroom atmosphere has become more active after the use of interesting chemistry experiments for teaching. The students' enthusiasm for answering questions has been greatly improved. Experimental studies show that interesting chemistry experiments can promote students' interest in learning, active classroom atmosphere, and promote students' love and pursuit of science. This study will continue to enrich and perfect interesting chemical experiments, summarize the results of the research, and continue to promote in the form of monographs, CDs and so on.
