ビデオ映像から読み取られた運動情報の内容分析

─小学2年生と6年生の記述内容の比較から─

This research aims to examine the motion information described by elementary school pupils after watching videos. Second graders and sixth graders of an elementary school were asked to describe in writing the techniques they observed in videos. We then compared the contents of the written observations of the two groups of graders. Subsequently, we discussed the written observations by classifying them into cases; case analysis revealed the following three points.
(1) While e second graders tended to focus on the preparation for a technique, the sixth graders used many nouns signifying parts of the body, such as leg, hand, back, and head, in their written observations.
(2) The sixth graders described the trunk of the body and legs and major phases of a technique. This indicates that the six graders tended to observe the moves essential for a technique.
(3) Some sixth graders described leg movements using a spatial image and timing and time lag between movements. Although some second graders also produced similar descriptions, their descriptions were exceptions. Analysis of the description contents of the second graders revealed that they were not adequately competent to explain the movements of the trunk of the body and legs.
