The report of the national response to intervention (RTI) evaluation study, conducted during 2011-2012, was released in November 2015. Anyone who has read the lengthy report can attest to its complexity and the design used in the study. Both these factors can influence the interpretation of the results from this evaluation. In this commentary, we…

In this article, we report the results from a randomized evaluation of the Safe and Civil Schools (SCS) model for school-wide positive behavioral interventions and supports. Thirty-two elementary schools in a large urban school district were randomly assigned to an initial training cohort or a wait-list control group. Results suggested that SCS…

When attempting to determine if an intervention has a causal impact, the "gold standard" of program evaluation is the randomized controlled trial (RCT). In education studies random assignment is rarely feasible at the student level, making RCTs harder to conduct. School-level assignment is more common but this often requires considerable resources…

Impact evaluations of special education programs can be designed and conducted to produce information useful for program improvement. Case studies of recent impact evaluation support this position. Assessment of program implementation and measurement of outcome--two critical areas that can greatly improve the usefulness of evaluation results--are…

Describes the Direct Instruction model, which has been effective in teaching mathematics to disadvantaged students. Results of the national Follow Through and the University of Oregon evaluations are reported, and implications of the findings for improving classroom practices are discussed. (RH)

Conclusion about site-specific determinants of educational outcomes of the controversial longitudinal evaluation of the Follow Through programs (1976) are challenged again by reexamining the Direct Instruction model data. Reanalysis confirms earlier critiques and supports more recent research funding on the relationship between types of…

A structured immersion program, coupled with an effective curriculum and empirically validated teaching procedure, was offered to elementary Asian students entering a California school. This approach appeared to have significantly better results, and its effects were maintained for up to two years after completion. (LMO)

Despite claims that structured immersion programs for language minority students cannot work for low-income students, two immersion projects with low-income Hispanic and Asian children worked; their effects appeared to endure even after students entered the mainstream. (BJV)
