The purpose of this study was to analyze the self-assessments of their own movement using a full-screen video and a dual-window comparison video. To do this, the study compared the descriptions by pupils who were elementary school 4th graders. The results of this study were as follows; It was surmised that for both the self-assessments using a full-screen video and the selfassessments using a dual-window comparison video adopted the instructions given by the teacher as the perspective for their assessment. Pupils wrote a larger number of descriptions excepting instructions given by teachers in case of the self-assessments of their own movement using a full-screen video than the self-assessments using a dual-window comparison video. This suggests that by using a dualwindow comparison video where one’s technique can be compared with model footage, it is easier to have a new viewpoint that allows them find differences in the movements.
