The Development Of High School Chemical Experiment And The Research On Teaching Application Based On The Transducer Technology

Transducer technology is closely related to modern science. It is easy-to-conduct, visual, real-time and accurate. Application of transducer technology to chemical experiment teaching not only makes it possible for students to carry out those experiments that are difficult to conduct through traditional methods, but also enhances students' understanding of the advanced science and technology, helps them obtain the scientific learning methods and form the correct learning attitude.To promote the use of transducer technology in high school chemical teaching, in this paper researches are conducted in two aspects, namely, chemical experiments development and their application on teaching. In the first part, transducer technology is combined with traditional experiments, making the chemical changes more visible and able to be tested quantitatively. In the second part, three turns of action researches have been done according to the action research pattern. After that measures and effects of transducer technology's application to chemical experiment teaching are discussed.According to this paper, transducer technology is a very important technology. In one hand, it overcomes the weakness of traditional laboratory equipments and makes those experiments that are hard to do through traditional way easy to conduct. In another hand, it is an innovation of chemical experimental apparatus and teaching method. More chemical experiments are available by using transducer technology. Applying transducer technology to inquiry learning leads to unprecedented teaching result and better learning efficiency. It plays an important role in inquiring study, especially in solving problems with fast reactions, complicated calculation, integrated disciplines and open end.In addition, the results of the research tell that in the class, helping students learn how to use sensors is more important than letting them know how sensors works, considering the limitation of their understanding. Before such experiments, teachers should make good preparation and give students full guide. In the end, the validity, feasibility of chemical teaching using transducer technology and students' agreement are analyzed.However, the application of transducer technology in the high school chemical teaching is far beyond this paper. It needs more exploration and refinery in the long-term research and teaching.
