At this time, we can use multimedia

At this time, we can use multimedia technology to assist our experimental teaching. For example, in the laboratory, students can't see experiments such as molecular diffusion, Brownian motion and α - ion scattering. If students can not get enough perceptual materials, it is easy to cause perceptual obstacles, and then affect the mastery of physical knowledge. Using multimedia technology, we can copy or simulate these experiments. With the help of multimedia technology, it can also demonstrate the ideal slope experiment affected by friction in real life, so that students can experience the great Galileo thought and the great changes of experimental thought brought by this experiment. Using multimedia technology, we can also simplify some complex physical problems, and transform the physical evolution process of α - ion scattering into the evolution process that can be controlled by human beings. Therefore, the introduction of multimedia technology into physical experiments not only provides students with a wealth of perceptual materials, so that students can perceive complete, clear and image physical phenomena and physical processes, but also enrich students' brains, stimulate students' interest in learning, and improve students' understanding and mastery of knowledge.
