The effectiveness of the high speeded visual contents for online education was examined in this paper. Three types of visual contents, which have the same content but different speed rates; 1.0x, 1.5x, and 2.0x, were showed to 75 subjects in the empiric test. The content covered declarative knowledge about information science in Japanese high school. Our main finding is that visual contents-speed rate doesn’t influence the post-video test results. Meanwhile, questionnaire survey shows that more subjects didn’t give a positive assessment about the visual contents played at 2.0x speed. Consequently, the possibility that 2.0x speed visuals can allow learners to study twice in a certain period of time is discussed.
