Martial arts short-armed sport is an important item of martial arts. At present, the martial arts short soldier movement in the society cannot be carried out due to various reasons. As a sports academy, it is our responsibility to shoulder this important task. With the popularization of the Internet and the rapid development of multimedia and network technologies, human society has entered an information age. Traditional classroom teaching has been unable to meet the requirements of the times. Due to its characteristics of remote real-time interaction, network education has become a new generation of educational technology that combines network and multimedia technology. Network course is the most important learning content in network teaching, and its design, development, and implementation have received more and more attention. With the rapid development of computer network technology, the status of computer-aided teaching in teaching improvement has also been continuously improved. Computer-assisted instruction (CAI) is a hot topic in today’s classrooms. In physical education, computer-aided teaching makes up for the shortcomings of illustrations, text descriptions, teacher explanations, demonstrations, etc., in textbooks and overcomes the shortcomings of traditional teaching aids. It simpliﬁes complex actions and concretizes non-decomposable actions. Computer-aided teaching can not only help students understand, master knowledge, and develop intelligence, but also help teachers master information and improve teaching quality. (is study studies the recognition and application eﬀect of CAI in the short-armed martial arts courses in physical education colleges.

Computers can soldiers themselves, it can be seen that martial arts short not only provide simple text, numbers, and other text soldiers are a valuable competitive sport.
