This investigation was designed to determine the frequency and extent of student unrest during the 1968-1969 academic year and to identify possible causal factors. The sample consisted of 382 colleges and universities which responded to a questionnaire concerned with the incidence of protest, their mode, the issues involved, the immediate consequences and any institutional changes occurring during the academic year. It was found that 22% of the institutions in the country had disruptive protests. The most frequent modes of protest were the occupation of buildings and disruption of school functions, and of the violent modes, damage to buildings and marches involving physical violence occurred most frequently. There was some relationship between issue and tactics and there was a general tendency toward "protest-proneness" at institutions which lacked cohesiveness and showed little regard for the students' welfare. Legal consequences and institutional discipline were almost entirely a response to violent tactics but legal action was more likely to occur when tactics were extreme, while increases in student power occurred independent of tactics. Various hypotheses were suggested for these findings. (RSM)
