Three before-and-after questionnaire studies were made to test the effectiveness of a simulation game called "Ghetto." In this game the player takes the role of a poor person living in an inner-city slum neighborhood. The education purpose of the game was to increase the players' understanding of the obstacles and hazards that the poor must face in their daily lives. Tests administered immediately after the game showed the players' attitudes toward the poor became more favorable. The results of later tests however did not show this effect. It was suggested that the game would be valuable at the beginning of a unit of instruction so that the temporary attitude change induced by the game would make the students more receptive to the related instruction which followed.
