Abstract: At present, media science is at a turning stage towards the development of cross-media. With its immersive, interactive and imaginative characteristics, the mixed media virtual simulation technology is applied in the teaching activities of science and engineering, while the film and television media majors with the background of literature, art and technology have potential for growth in the teaching and application of virtual simulation technology. Based on the analysis of the practical teaching difficulties of film and television media, this paper discusses the three dimensions of the application of virtual simulation technology in cross-media teaching, for instance, how to apply science and engineering thinking in the field of humanities and social sciences, which may solve the problems of insufficient experimental resources and imperfect practical training model, thereby promoting its demonstration and leading role in the training of journalism & communication applied talents.
