This qualitative and quantitative study examines the potential improvement in aggressive student behaviors when a block schedule is implemented in a rural, low socio-economic and multi-cultural middle school. The number of incidents of physical aggression and harassment were obtained from official school records for the years 1992-1996. Interviews were also conducted with staff members who had long term tenure in the school and who had a clear vision of student behaviors both pre and post-block schedule implementation. The face value of the school record data suggest a dramatic improvement in student behaviors. These data corroborate very closely with interview information. Teachers believe behaviors have substantially improved. In 1992-1993 there were 30 assaults in the school. In 1993-1994 there were 15, in 1994-1995 there were 0, in and in 1995-1996 there were 4. The substantive conclusion is the development and implementation of a block schedule in this particular middle school was highly successful in helping alter the aggressive behaviors of students. / Graduation date: 1997
