Application and Strategy of Computer Multimedia Technology in College Students' English Reading and Writing Teaching

With the rapid development of information technology, computer multimedia technology has become one of the important means to improve the quality of higher education teaching. This paper aims to explore the application of computer multimedia technology in college students' English reading and writing teaching and its optimization strategy. First, the target tracking algorithm under the computer multimedia algorithm is studied. CamShift, Kalman filtering and other technologies are used to achieve real-time tracking of multimedia classroom courseware, and the angle of the camera is automatically adjusted according to the position of the teacher to achieve better recording effect. Then, a questionnaire survey was conducted on teachers and students of a certain university, and a one-month teaching was carried out. Finally, the results were verified by examinations. The experimental results show that the average reading and writing scores of the two classes before teaching are basically the same, and the average reading and writing scores of the experimental class after teaching are also basically the same, but the scores have surpassed the control class, with an average score of 3.3 points higher. It can be seen that multimedia-assisted teaching helps to improve students' reading and writing scores.
