This paper describes the development and practice of high school field work teaching materials using smart phones and tablets. In addition, this paper examines effects and problems based on practice. In field work it is difficult to find the feature to be observed. Here is an advantage of using the Augmented Reality (AR) application. AR (Wikitude and GISAR) and Google Maps were used in practice at Waseda Senior High School. As a result, AR proved to be useful. However, AR was not fully utilized. Therefore, a method to effectively utilize AR is examined in this paper.
