The purpose of this study was to make visible the actual situation of spatial images of students. For this purpose, the authors analyzed a viewpoint locating process that was considered necessary in improving spatial cognition. The authors investigated by using three viewpoints. These were on getting a spatial image from three or two dimensional figures and locating relative viewpoints in a spatial image. The results were as below : (1) It was possible for the students to locate a viewpoint in case there was only a single direction. Therefore, the students could obtain spatial image from the figure on a paper. On the other hand, the students could not do it in case the directions are many. (2) Inside a spatial image, the students could rotate the whole frame of the image they possess. However, a partial operation was difficult. (3) It became clear that the third graders of the junior high school were on the transitional period toward the higher step of spatial cognition.
