Abstract
Human society is now facing serious environmental problems. It is necessary to build a sustainable society in which human economic activities and nature can exist together. To achieve this, environmental education is seen as a way to encourage the youth to have broad perspectives and cooperative attitudes in regard to environmental problems. This study thus aims to develop a card game “GAWL,” based on the Monopoly DEAL, which enables the youth to have this perspective attitude regarding environmental problems through communication among players. This game consists of 146 cards in the three categories of effect, action and eco-point. Using these cards, players gather more ecopoints and develop cooperative attitudes in regard to preventing global warming. Experimental testing of the game was conducted with 12 university students as subjects. In quizzes on selecting environment-friendly actions, the correct answer ratio changed from 44.4% to 66.7% before and after the game. In response to a questionnaire, all of the students answered that they could have fun with the game. These results verified the educational effectiveness of the game.
