The purpose of this study is twofold. First, to develop a 3DCG teaching material for strata that can be displayed in AR. Second, to evaluate the developed 3DCG teaching material. To achieve the second objective, we conducted a classroom practice for third-year junior high school boys using the developed teaching material. The evaluation of the teaching material was based on the following three points. First, the impact of the 3DCG display method on immersion. Second, the characteristics of stratigraphic observations using 3DCG materials. Third, the influence of prior learning using 3DCG stratigraphic materials on the perception of geological events in the field during field trips and other outdoor activities that do not involve planned stratigraphic observations. The results of the classroom practice suggested the following three points. First, AR display is generally evaluated as having higher immersion than conventional desktop display, although there are differences depending on the item. Second, in observations using stratigraphic 3DCG materials, differences were found between items with regard to the ease of recognizing geological events and three-dimensional features. Third, observing strata in the 3DCG teaching materials in advance makes it easier to recognize the elements that constitute strata in field observation.
