The general purpose of this study is to investigate the effects of education or common schooling upon the attitudes of high school students who are socialized in tribal societies and who belong to different sociocultural groups within the total society. The specific problem is to conceptualize the independent variables which can be considered to have theoretical relevance for the formation of interpersonal attitudes, to derive from them conditions of interpersonal experience which can be expected to lead to the formation of positive attitudes, and to test the relationship between experience and attitude in an experimental design in a field setting. Chapters discuss: 1) theory of conditions of interaction to promote positive attitudes; 2) population and experimental sample; 3) treatments of forced compliance and participation in goals, observation of interaction, attitude scales, sociometric test, measurement of actual associations, testing procedures; 4) statistical results and inferences; and, 5) theoretical and practical significance, i.e. under certain conditions, different patterns of classroom interaction do affect intergroup attitudes, and lead to better understanding of the relationship between education and the integration of social and political communities.
