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…

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)

This paper reviews both the content and the methodological issues involved in the small but growing number of empirical studies on the use of Direct Instruction programs and teaching procedures with special populations. The research reviewed includes experimental and quasi-experimental work, summative evaluations of entire programs, and…

The evolution and evaluation of an elementary level structured immersion program in English as a second language are described. The program provides all academic instruction in English, but at a level that students can understand. It is ungraded, uses bilingual teachers who speak the students' native language, and has both developmental and direct…

A study assessed and compared the effectiveness of two distinct approaches of bilingual education used within a single school district in El Paso (Texas). The program designs, one a traditional transitional bilingual and the other a bilingual immersion, were implemented under similar conditions of resources, school year length, class size, and…

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)
