What are the characteristics of dis experiments? What are the advantages of introducing dis experiment in secondary school chemistry laboratory teaching

DIS experiment is introduced into the process of high school physics experiment teaching with the new curriculum reform of high school physics, which is a kind of experimental method closely related to modern science, and has the characteristics of convenient, intuitive, real-time, accurate and so on. Adopting DIS to design high school physics experiment teaching not only makes certain experiments that cannot be realized by traditional experimental methods successfully completed, but also prompts students to understand advanced science and technology, acquire scientific learning methods, and form correct learning attitudes. However, in the process of teaching high school physics "mechanics" experiments, not all experiments are suitable for DIS to complete. This paper combines the characteristics of DIS experiments and traditional experiments, analyzes their respective advantages and disadvantages, and experimental comparisons, and finally, through research and comparison, the majority of experiments involved in high school physics, "mechanics" in the analysis and study of individual textbooks on the existing DIS experimental design program proposed improvements. Opinions, the purpose is to make the changes in the experimental process is more clear, the phenomenon is more clear, and the improved design can reflect the changes in the experimental process from a quantitative point of view, change the traditional way of teaching experiments, so that the experimental teaching is more effective.
