In 2007, Randolph conducted a meta-analysis of response-card articles to determine the effect of response cards on test achievement, quiz achievement, class participation, and off-task behavior. This meta-analysis is an update of that analysis, including new studies conducted in the last 12 years. A total of 15 studies published between 2005 and…

School voucher programs are scholarship initiatives -- frequently government funded or incentivized -- that pay for students to attend private schools of their choice. This study is the first formal meta-analytic consolidation of the evidence from all randomized controlled trials (RCTs) evaluating the student-level math and reading test score…

This report presents findings from exploratory, descriptive meta-analyses of effect sizes reported by the first 82 EEF evaluations that used a randomised controlled trial (RCT) or clustered RCT impact evaluation design published up to January 2019. The review used a theoretical framework derived from literature with five overarching themes to…

We meta-analyze for impact and cost-effectiveness 94 studies from 47 conditional cash transfer programs in low- and middle-income countries worldwide, focusing on educational outcomes that include enrollment, attendance, dropout, and school completion. To conceptually guide and interpret the empirical findings of our meta-analysis, we present a…

Asthma is the leading chronic health condition among children in the United States and a major cause of childhood disability. It also disproportionately affects low-income and racial and ethnic minorities. Although a wide range of interventions have been implemented to improve asthma-related outcomes among socioeconomically disadvantaged and…

I gathered 77 randomized experiments (with 111 treatment arms) that evaluated the effects of school-based interventions on learning in developing-country primary schools. On average, monetary grants and deworming treatments had mean effect sizes that were close to zero and not statistically significant. Nutritional treatments, treatments that…

This article systematically reviews the cost study literature as it relates to the treatment of English language learners (ELLs). Despite the substantial number of costing out studies that have been conducted over the past several decades, the school finance literature has failed to focus on ELLs--the fastest growing segment of the school-age…

Discusses the cost effectiveness of training interventions for industry and education. Highlights include the differences between cost-benefit analysis and cost-effectiveness analysis; measuring effects; the development of meta-analysis; cost and its measurement; cost-effectiveness ratios; and an example of the cost-effectiveness of computer-based…

Several available summaries of research on coaching for the Scholastic Aptitude Test (SAT) are summarized and their principal findings discussed. Some additional studies, that have been completed since these summaries were reported, are considered and linked to the summaries. The four major meta-analyses considered are those of: (1) Messick and…

Focuses on alternative paradigms to experimental inquiry useful to instructional systems researchers, including quasi-experimentation, meta-analysis, case study and ethnography, systems-based evaluation, and technique and model development. Each is discussed in terms of how it generally applies in the field and how it has been employed by…

This meta-evaluation provides a standardized look at the quality of the economic evaluation literature for multi-component worksite health promotion programs. Analysis of 42 studies suggests that the evidence is very strong for average reductions in sick leave, health plan costs, and workers' compensation and disability costs of slightly more than…

This paper contains summaries of the findings of research and meta analyses conducted on the effectiveness of computer-based instruction (CBI) on student achievement. Eight conclusions, based on the CBI research are then given: (1) when CBI and traditional instruction are compared, students receiving CBI demonstrate equal or better achievement;…

An analytic review of interactive videodisc instruction applied in defense training, industrial training, and higher education found that academic achievement was improved in all settings when interactive video was used. Interactive video was more effective when more interactive features were used, was less costly than other instructional methods,…

This study was performed in response to the 1989 Department of Defense Appropriations Bill, which directed the Department of Defense to conduct a study on the use of interactive videodisk technology in education and training as it pertains to effectiveness, cost effectiveness, time on task, retention, and overall applicability to current and…

Compares the effects of peer tutoring and computer-based instruction on student achievement and motivation through a meta-analysis of research. Cost effectiveness is also investigated via ratios which combine the effects of the intervention with estimates of implementation costs, and an appendix includes reviews of 10 cost-effectiveness research…
