The purpose of this study wasņto grasp the current situation of performanceņduring practices and games in class using volleyball as teaching materials, and to clarifyņa gap between the two. For that purpose, we collected data from the video of the class and examinedņthe ball movement during the game. During pass practice between two people, the most typical class activity, theņball trajectory was not changing direction and was the same distance, but the ball movement during the game was diverse and complicated. There were many direction changes and trajectory changes inņthe ball movement during the game. During the game, the ball trajectory was changing direction over varying distances, and the ball was not returned to the same person in many cases, as it was during pass practice between two people. It was found that there wasņa gap between practices and games, with many differences in performance between them.
