Abstract
This Study was conducted to analyze the reliability of pupil's self-awareness. Because we must sometime depend on their self-awareness during school hours. Then, it was begun experimenting in. high jump. Thirty-eight boys and thirty-two girls in the fourth grade or fifth grade participated in this experiment. A bar of high jump was set from 50cm at first, and lifted up every 10cm to 100cm. They were asked every time whether they were confident of success or not before jumping. As a result, we could know that pupil's self-awareness (metacognition) could be reliable, and that it was dependent on his experience (metaexperience) which afforded him great information.
