Bloom, Howard S. – Journal of Research on Educational Effectiveness, 2012
In this article, the author shares his comments on statistical analysis for multisite trials, and focuses on the contribution of Stephen Raudenbush, Sean Reardon, and Takako Nomi to future research. Raudenbush, Reardon, and Nomi provide a major contribution to future research on variation in program impacts by showing how to use multisite trials…

Jo, Booil; Stuart, Elizabeth A. – Journal of Research on Educational Effectiveness, 2012
The authors thank Dr. Lindsay Page for providing a nice illustration of the use of the principal stratification framework to define causal effects, and a Bayesian model for effect estimation. They hope that her well-written article will help expose education researchers to these concepts and methods, and move the field of mediation analysis in…

VanderWeele, Tyler J. – Journal of Research on Educational Effectiveness, 2012
Principal stratification provides an approach to study the effect of an exposure on an outcome within strata defined by the effect of the exposure on some third, posttreatment, variable (Frangakis & Rubin, 2002). There has been more recent interest in using principal stratification to study the extent to which the effect of an exposure on an…

Raudenbush, Stephen W.; Reardon, Sean F.; Nomi, Takako – Journal of Research on Educational Effectiveness, 2012
This article presents the authors' rejoinder to the comments of Howard Bloom, Derek Neal, and Mike Seltzer on their article. Their commentary focused foremost on the advantages and disadvantages of using Options A, B, or C in using instrumental variables in multisite trials. Of interest are the quantities one can estimate and test in each case,…

Bloom, Howard S. – Journal of Research on Educational Effectiveness, 2012
This article provides a detailed discussion of the theory and practice of modern regression discontinuity (RD) analysis for estimating the effects of interventions or treatments. Part 1 briefly chronicles the history of RD analysis and summarizes its past applications. Part 2 explains how in theory an RD analysis can identify an average effect of…

Reardon, Sean F.; Robinson, Joseph P. – Journal of Research on Educational Effectiveness, 2012
In the absence of a randomized control trial, regression discontinuity (RD) designs can produce plausible estimates of the treatment effect on an outcome for individuals near a cutoff score. In the standard RD design, individuals with rating scores higher than some exogenously determined cutoff score are assigned to one treatment condition; those…

Gelman, Andrew; Hill, Jennifer; Yajima, Masanao – Journal of Research on Educational Effectiveness, 2012
Applied researchers often find themselves making statistical inferences in settings that would seem to require multiple comparisons adjustments. We challenge the Type I error paradigm that underlies these corrections. Moreover we posit that the problem of multiple comparisons can disappear entirely when viewed from a hierarchical Bayesian…

Imai, Kosuke – Journal of Research on Educational Effectiveness, 2012
The author begins this discussion by thanking Larry Hedges, the editor of the journal, for giving him an opportunity to provide a commentary on this stimulating article. He also would like to congratulate the authors of the article for their insightful discussion on causal mediation analysis, which is one of the most important and challenging…

Page, Lindsay C. – Journal of Research on Educational Effectiveness, 2012
Experimental evaluations are increasingly common in the U.S. educational policy-research context. Often, in investigations of multifaceted interventions, researchers and policymakers alike are interested in not only "whether" a given intervention impacted an outcome but also "why". What "features" of the intervention…

Raudenbush, Stephen W.; Reardon, Sean F.; Nomi, Takako – Journal of Research on Educational Effectiveness, 2012
Multisite trials can clarify the average impact of a new program and the heterogeneity of impacts across sites. Unfortunately, in many applications, compliance with treatment assignment is imperfect. For these applications, we propose an instrumental variable (IV) model with person-specific and site-specific random coefficients. Site-specific IV…

Jacob, Robin Tepper; Jacob, Brian – Journal of Research on Educational Effectiveness, 2012
Teacher and principal surveys are among the most common data collection techniques employed in education research. Yet there is remarkably little research on survey methods in education, or about the most cost-effective way to raise response rates among teachers and principals. In an effort to explore various methods for increasing survey response…

Castleman, Benjamin L.; Arnold, Karen; Lynk Wartman, Katherine – Journal of Research on Educational Effectiveness, 2012
The summer after high school graduation is a largely unexamined stage of college access among underrepresented populations in higher education. Yet two recent studies revealed that anywhere from 10% to 40% of low-income students who have been accepted to college and signaled their intent to enroll reconsider where, and even whether, to matriculate…

Wei, Xin – Journal of Research on Educational Effectiveness, 2012
The No Child Left Behind Act (NCLB) holds public schools accountable for the academic achievement of student subgroups that are larger than the state minimum-subgroup-size threshold. In 2004, California added students with disabilities to the NCLB subgroup categories. Using a regression discontinuity design, this study compared the academic…

Apthorp, Helen; Randel, Bruce; Cherasaro, Trudy; Clark, Tedra; McKeown, Margaret; Beck, Isabel – Journal of Research on Educational Effectiveness, 2012
A cluster randomized trial estimated the effects of a supplemental vocabulary program, Elements of Reading[R]: vocabulary on student vocabulary and passage comprehension in moderate- to high-poverty elementary schools. Forty-four schools participated over a period spanning 2 consecutive school years. At baseline, 1,057 teachers and 16,471 students…

Edmunds, Julie A.; Bernstein, Lawrence; Unlu, Fatih; Glennie, Elizabeth; Willse, John; Smith, Arthur; Arshavsky, Nina – Journal of Research on Educational Effectiveness, 2012
Early college high schools are a new and rapidly spreading model that merges the high school and college experiences and that is designed to increase the number of students who graduate from high school and enroll and succeed in postsecondary education. This article presents results from a federally funded experimental study of the impact of the…
