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. In rating the quality of causal research, the WWC has historically prioritized internal validity over external validity. One…

This systematic review synthesizes fluency intervention research for struggling readers in Grades 6 through 12 from January 2006 to October 2019. The search yielded 17 studies examining reading fluency and comprehension outcomes. Most studies examined repeated reading (RR) interventions to improve reading fluency for struggling readers at these…

Inconsistent reporting of critical facets of classroom interventions and their related impact evaluations hinders the field's ability to describe and synthesize the existing evidence base. In this essay, we present a set of reporting guidelines intended to steer authors of classroom intervention studies toward providing more systematic reporting…

Purpose: The purpose of this study is to determine the quantity, nature and frequency of intervention research published in Human Resource Development (HRD) journals. Design/methodology/approach: The methodology for this study was a literature review, analysis and synthesis with specific attention to locating intervention research in HRD journals.…

Historically, the synthesis of single subject design has employed visual inspection to yield significance of results. However, current research is supporting different techniques that will facilitate the interpretation of these intervention outcomes. These methods can provide more reliable data than employing visual inspection in isolation. This…

One of the key findings from decades of educational effectiveness research is the importance of the classroom level as a predictor of pupil outcomes. In this review, we therefore look at synthesising our best evidence from research on effective teaching, and its corollary, teacher development. In the 1st section, we will look at key findings from…

This article synthesizes the experimental literature on reading interventions for upper elementary and middle school students identified with reading disabilities on norm-referenced reading measures. Ten studies (12 independent samples) yielded 70 effect sizes on norm-referenced reading measures with an aggregated mean of 0.41 (SE = 0.04) in favor…

This paper presents an extensive overview of preschool to 12th grade (P-12) engineering education literature published between 2001 and 2011. Searches were conducted through education and engineering library engines and databases as well as queries in established publications in engineering education. More than 50 publications were found,…

The critical issue in special education today is no longer the assurance of access, but rather, the assurance of effectiveness. Determining which practices and interventions are most effective and efficient for ensuring optimal student achievement is a fundamental concern of special education teachers in this era of accountability. In this…

The educational achievement and attainment of young people in the United States has been a long-standing issue of concern. While analyses of long-term trend data from the National Assessment of Educational Progress (NAEP) show that students in the United States have made gains in reading and mathematics over the past few decades, a sizeable…

This article reports a synthesis of intervention studies conducted between 1994 and 2004 with older students (Grades 6-12) with reading difficulties. Interventions addressing decoding, fluency, vocabulary, and comprehension were included if they measured the effects on reading comprehension. Twenty-nine studies were located and synthesized.…

Because research synthesis enables one to determine either the overall effectiveness of a particular treatment or the relative effectiveness of different types of treatments, it is becoming increasingly popular as a tool in program evaluation. Numerous methodological problems arise, however, when research synthesis is applied to studies conducted…

An overview is provided of a 5-year project conducted by the Early Intervention Research Institute (EIRI) which focused on the effects and costs of early intervention for young handicapped children. The bulk of the document consists of research reports of 14 investigations: (1) meta-analysis of the early intervention efficacy literature; (2)…

The IADIS CELDA 2012 Conference intention was to address the main issues concerned with evolving learning processes and supporting pedagogies and applications in the digital age. There had been advances in both cognitive psychology and computing that have affected the educational arena. The convergence of these two disciplines is increasing at a…
