Abstract: Based on the inherent characteristics of physics,multimedia technology has increasingly become an indispensable auxiliary teaching method in junior high school physics teaching. Compared with the traditional single teaching model,physics teaching supported by multimedia technology can become more intuitive,vivid and interesting. The scientific utilization of multimedia technology characteristics stimulates students' interest in learning and thirst for knowledge. It involves setting the content,methods,and rhythm of multimedia-assisted teaching in a reasonable manner to adapt to the actual teaching needs. Additionally,it involves effectively utilizing multimedia simulations and reproduction function to optimize experimental teaching. It can guide and help students understand physical phenomena and theories from a broader perspective,gradually establish a sense of scientific inquiry,greatly improve the effect of classroom and experimental teaching,and improve teaching results.

Key words: junior high school physics, teaching, multimedia technology, application
