Introduction: The What Works Clearinghouse (WWC) reviews rigorous research on educational interventions with a goal of identifying "what works" and making that information accessible to educators and policymakers. The WWC has historically prioritized internal validity over external validity in rating the quality of research. One critique…

We conducted a systematic literature review examining the participant characteristics of studies of students with emotional disturbance (ED) with the purpose of better understanding potential similarities and differences between students with ED in research and the population of students with ED. Results indicate (a) participants with reported…

This meta-analysis examined the ecological and population validity of intervention research for students with low mathematics achievement (SWLMA). Forty-four studies published between 2005 and 2019 that met the inclusionary criterion were included in this analysis. Our findings suggest, to improve the external validity and generalizability of…

The purpose of this scoping review is to critically examine empirical research that draws on first-person experiences of schooling among students with autism or attention-deficit/hyperactivity disorder (ADHD) as well as to map whose voices are heard in research and where the current knowledge gaps are. The review examined key characteristics of…

The evidence base for educational interventions for deaf students has been, and continues to be, called into question due to a lack of "gold standard" research available to support it. Yet the paucity of research in deaf education is not only in the volume of research that meets rigorous standards but also in its lack of attention to and…

Forty years ago, the National Center for Education Statistics initiated the national longitudinal studies program in response to congressional concern for policy-relevant information on school-to-work transitions. This program has grown substantially, and not unexpectedly, questions have arisen about its usefulness and present operation. This…

This report summarizes the complex research literature on quantitative methods for assessing how impacts of educational interventions on instructional practices and student learning differ across students, educators, and schools. It also provides technical guidance about the use and interpretation of these methods. The research topics addressed…

The Early Childhood Educator Survey and the Early Childhood Administrator Survey allow users to collect consistent data on the use of child assessments and learning standards in early childhood learning settings. Each survey includes modules on educator/administrator background information, assessment use, and learning standards implementation.…

Purpose: Recent educational research has demonstrated rural-urban gaps in achievement and schooling conditions. Evidence from developing countries is still sparse. This study seeks to report rural-urban disparities in achievement, student, teacher, and school characteristics based on a nationally representative sample of grade four students from…

One purpose of educational research is to provide information about the likely impact of interventions or treatments on policy-relevant populations of students. Randomized experiments are useful for estimating the causal effects of interventions on the students in schools that participate in the experiments. Unfortunately, the samples of schools…

One of the aims of this study was to recognize whether a change had occurred in the self-concept of Returning Women Students (RWS) between a previous academic experience and their return to formal education. (Author/RK)

The present research again demonstrates the strong link between social class background and early leaving, but, interestingly, when stated leaving preference was controlled for, no relationship between social class background and conceptions of school was detected. (Author)

Many school-based research efforts require active parental consent for student participation. Maximizing rates of consent form return and agreement is an important issue, because sample representativeness may be compromised when these rates are low. This article compares two methods for obtaining active parental consent: return of consent forms in…

Author wrote about his research into the career choices of British undergraduates. School teaching, surprisingly, headed the list. (Editor/RK)

Nonreturn of mail surveys was described in this paper in terms of selectivity bias, that is, the bias introduced in survey results due to respondents and nonrespondents differing in unmeasured and unmeasurable ways that might yield inconsistent population estimates. (CT)
