Social relations data is an especially useful but often neglected means of obtaining information on the effects of social processes that are involved in educational interventions. A four-fold table conceptualizes educational interventions and their outcomes as consisting of social and academic interventions and their outcomes. This model characterizes programmatic interventions as a mechanism for changing opportunities and making interaction more or less convenient. The model is applied to evaluation of two nationwide policies that call for social intervention in public education: racial desegregation and the mainstreaming of mildly handicapped children. In the case of desegregation, data include numerical levels of desegregation, the level of effort, and the repeated measures of social interaction. The outcome noted is the level of integration across various settings. The optimum process for developing data on social outcomes is sociometric testing. (LP)
