Algorithm of Modern Information Technology Applications and Data Fusion in Volleyball Teaching of College Sports

With the rapid development of human society and knowledge economy, information technology is also undergoing tremendous changes. The emergence of modern information technology has given us a new choice to optimize the educational process and improve educational efficiency. Modern information technology promotes knowledge to students in comprehensive forms such as text, images, sound, comics, and videos, and improves the guidance of volleyball courses. The application of new technology has stimulated students' interest in sports knowledge and sports technology, increased their enthusiasm for learning, broadened their horizons of knowledge, and improved the effect of education. This article adopts research methods such as literature data method, questionnaire survey method, expert interview method, and experimental teaching method. Based on many professional theoretical books related to volleyball and modern information technology, as well as the application status of modern information technology, the teaching application of professional volleyball has been deeply studied. The results of the experiment showed that the scores of the control group on the theoretical knowledge test of volleyball increased by about 8 points compared with the pre-experiment, and the experimental group increased by about 13 points. In contrast, the scores of the experimental group were significantly higher than those of the control group.
