What would be a good research question with regard to school desegregation in Boston?

The most important research area for the desegregation of Boston public schools is the period between 1974 and 1988. During this period, Boston did not have the sort of Jim Crow laws that had been so overtly discriminatory in the South, but nonetheless had de facto racial and economic segregation of public schools as a result of segregated neighborhoods. In response to a court order making segregation illegal, Boston instituted a policy of busing students to school districts outside their neighborhoods to reduce school segregation. There was a massive backlash against this policy. Although some consider that the policy succeeded in some of its objectives, over the long term racial composition of schools is still affected by many factors outside of control of school districts.
In order to research this topic, about which much has been written, one should narrow it to study a specific school or other limited topic. One possibility would be to look at the efforts to desegregate the elite public Boston Latin School and the subsequent legal challenges to racial preferences in admissions. Another well-documented case is the violence surrounding desegregation of South Boston High School. Finally, one could look at schools that were desegregated in the late twentieth century and examine the degree to which the program of desegregation succeeded or failed in terms of the degree to which schools have now been re-segregated.
