The paper discusses the impact of a semester-abroad political science program on the attitudes and behavior of college students. Participants included 52 students in a 1977 Kent State University Geneva Semester Program. The hypothesis was that positive attitude changes on worldmindedness would: (1) occur among students participating in the study abroad program; (2) relate positively to the enjoyment of the students' overall experience; and (3) relate positively to the closeness of contact with non-Americans. For the study, questionnaires were administered which focused upon attitudes of worldmindedness, support for the United Nations, self-esteem, and ambiguity. Responses of participants in the study abroad program were compared with responses of 17 students in a class on international organization at Kent State University. Findings based on simple percentages and multiple regression analysis of responses indicated that significant change occurred on only one variable, self-esteem. The conclusion is that relatively brief experience in another culture has a limited impact on attitudes such as worldmindedness and ethnocentrism. A major implication of the study is that claims about the potential of overseas study programs to produce attitude and behavioral changes among student participants should be given careful scrutiny.
