This research reports on factors concerning the correlation between quality of presentations and use of media resources. To do this, the study developed evaluation criteria based on prior research and collected data from 607 research participants. The data were analyzed according to regression analysis, three-way ANOVA, and ANCOVA. The results were as follows. First, factors on the quality of presentations with media resources are five types of discourse. Second, factors pertaining to writing were more powerful than factors pertaining to speaking, provided ability to construct content was controlled. Third, some students were poor at constructing content but good at using multimodalities for writing while other students were good at constructing content but poor at designing slides. Fourth, even if the student had a high level of content composition, teaching “interaction with audiences” could improve the quality of their media presentations. In this paper, multiple regression analysis was conducted to derive regression coefficients. It is possible to further elaborate this study and also to construct theoretical models by using Amos to explore the mediating effect between variables of media presentations.
