The Effect of Research Methodology on Desegregation – Achievement Studies: A Meta-Analysis

  • Grade of desegregation is significantly related to both magnitude and the sign of the treatment effect.
  • Longitudinal randomized experiment always has the largest positive coefficient, and the longitudinal design with justified control group has the second largest.
  • A positive treatment effect can be identified.
  • Much of the discrepancy among studies of desegregation and achievement can be attributed to methodological differences.
  • Desegregation is not a treatment and shouldn’t be studied as one.
  • Focus should be on the curriculum and community reactions.
