To address the problems of poor compatibility, weak load capacity, and time consumption of existing multimedia-assisted
teaching systems, we propose and design a physics multimedia-assisted English teaching system based on a concept network. The
architecture of the physics multimedia-assisted teaching system is constructed with the logical layer as the core, and the theoretical
knowledge module, experiment module, and student practice module are designed, respectively. Based on the concept network, a
large number of rules in the physics teaching system are attached to the concepts to form the concept network knowledge system
and complete the design of the theoretical knowledge system. This paper explores the multimedia teaching of college English and
points out the advantages and characteristics of this teaching mode and the problems to be paid attention to in the process of
application. The design of the physics multimedia-assisted teaching system is completed by realizing students’ practice and giving
feedback on the practice results. The experimental results show that the system has good compatibility, strong load capacity, low
time consumption, and practical application value.
