Understanding the seasonal diurnal motion of the sun is difficult. Previous research has suggested that students have learned incorrect concepts and that these were not corrected even after studying. This study aims to help students comprehend the diurnal motion of the sun using a 360° panoramic video, based on the body motion, which traces the motion of the sun. In Practice 1, the effect of the embodied cognition was confirmed using the 360° panoramic video. It was observed that those students who had problems in drawing a celestial sphere model showed an improvement in their ability to do so. However, there were problems in assimilating the azimuths of sunrise and sunset. Practice 2 involved actions with a 360° panoramic video having grid lines and actions of filming and overlooking one's body motion. The gridline class demonstrated an improvement in understanding sunrise and sunset. The filming class, however, exhibited limited efficacy. It is presumed that one of the causes of the results is the necessity of advanced cognition in order to comprehend the diurnal motion viewed from the ground based on overlooking one's own posture.
