In the Unplugged, there is an activity of learning Sorting Algorithm by using a set of a balance scale and some weights, as an educational material. Students can learn how computers work through repeating the comparisons of two weights assumed as data. However, through the lessons in shools, we recognized there were some ploblems in the activity. The first problem was that students did not compare data, if students could feel which weight was heavier/lighter in their hands. The second problem was that students could not understand algorithms if the balance scale could not measure with accuracy. To solve these problems, we focused on 'AR Technology'. AR is a new technology consisted of special markers and Web camera. We developed 'AR Balance Scale' as an educational material. This report shows how we designed AR balance scale and discuss the possibility of the educational material in school lessons.情報教育シンポジウム2014論文集201422532592014-08-172015-02-03
