It is difficult for consumers to access the evidence base for prevention programs to determine which models or practices have the strongest empirical support for improving youth social, emotional, and behavioral (SEB) outcomes within their specific service contexts. Researchers can address this evidence-to-practice gap through innovations in…

The What Works Clearinghouse (WWC) Standards Briefs explain the rules the WWC uses to evaluate the quality of studies for practitioners, researchers, and policymakers. This brief explains what baseline equivalence is and why it matters. As part of the WWC review process for certain types of studies, reviewers assess whether the intervention group…

This report includes findings regarding demographic characteristics and academic outcomes of DELTA students; highlights emerging topics from the student, teacher, and staff surveys; and provides recommendations for future program implementation.

Regression discontinuity (RD) designs are increasingly used by researchers to obtain unbiased estimates of the effects of education-related interventions. These designs are applicable when a continuous "scoring" rule is used to assign the intervention to study units (for example, school districts, schools, or students). Under an RD…

Educational researchers frequently study the impact of treatments or interventions on educational outcomes. However, when observational or quasiexperimental data are used for such investigations, selection bias can adversely impact researchers' abilities to make causal inferences about treatment effects. One way to deal with selection bias is to…

Nationwide, close to 40 million adults lack a high school diploma or a General Educational Development (GED) credential. About a quarter of high school freshmen do not graduate in four years, and while many high school dropouts eventually do attend GED preparation classes, too few ever pass the GED exam or go on to college. Students with only a…

Education research rarely lends itself to large scale experimental research and true randomization, leaving the researcher to quasi-experimental designs. The problem with quasi-experimental research is that underlying factors may impact group selection and lead to potentially biased results. One way to minimize the impact of non-randomization is…

This document is an appendix that is meant to accompany the main report, "Analysis of Private Returns to Vocational Education and Training". Included here are the detailed regression results that correspond to Tables 4 to 59 of the main report. This document was produced by the authors based on their research for the main report, and is…

In this set of four supplemental tables, the authors compare the baseline test scores of the treatment and matched control group samples observed in each year after KIPP entry (outcome years 1 to 4). As discussed in Chapter III, the authors used an iterative propensity score estimation procedure to calculate each student's probability of entering…

Previous studies have reported working memory deficits in autism, but this finding has been inconsistent. One possibility is that deficits in this domain may be present only when working memory load exceeds some limited capacity. High-functioning individuals with autism performed the CANTAB computerized test of spatial working memory. Individuals…

This article discusses the difficulties in conducting intervention research or evaluating intervention programs in a school setting. In particular, the problems associated with randomization and obtaining control groups are examined. The use of quasi-experimental designs, specifically a paired comparison design using the individual as his or her…

The goal of this project was to develop and test the efficacy of a research-based early reading program that provided integrated reading instruction in kindergarten through 2nd grade. The Reading and Integrated Literacy Strategies (RAILS) program provided integrated instruction in word reading, vocabulary development, and comprehension to students…

Describes a technique to make multistage cluster sampling easier for students to understand. Explains that students handle concrete objects that are analogous to the sampling units of a multistage cluster sampling procedure. Suggests that this method is inexpensive, easily organized, and stimulates the tactile senses in the learning process. (DK)

Special education teacher preparation programs typically require training in delivery of standardized achievement assessments. Appropriate administration of standardized assessments in eligibility and instructional planning process are critical. To insure production of valid assessments, pre-service teachers at Utah State University must deliver a…
