The purpose of this study is to examine what kinds of motion information students can obtain from video images. Students of various ages from third-graders in elementary school to second-graders in junior high school observed a video-teaching material showing dual-screen playback of the “straddle vault” and were asked to describe what they noticed about the performance. The analysis results of descriptions collected from a total of 569 students indicated the following two points:
1) Regarding the categories of momentum and speed, as well as about the overall performance, a greater proportion of junior high school students tended to give descriptions, while fewer elementary school students of middle years tended to do so;
2) With regard to positional relations of body parts, especially the categories that involve fast motion, elementary school students of middle years were inclined to describe less. By contrast, they described more about landing, suggesting that it was easier for them to focus their attention when the motion was halted.
