Over the past 15 years, we have seen an increase in the use of cluster randomized trials (CRTs) to test the efficacy of educational interventions. These studies are often designed with the goal of determining whether a program works, or answering the what works question. Recently, the goals of these studies expanded to include for whom and under…

This meta-analysis synthesized the findings from 23 published and five unpublished experimental or quasi-experimental group design studies on word problem-solving instruction for K-12 students with learning disabilities (LD) and mathematics difficulties (MD). A secondary purpose of this meta-analysis was to analyze the relation between treatment…

Background: The use of randomised controlled trials (RCTs) in education has increased significantly over the last 15 years. However, their use has also been subject to sustained and rather trenchant criticism from significant sections of the education research community. Key criticisms have included the claims that: it is not possible to undertake…

Tiered evidence initiatives are an important federal strategy to incentivize and accelerate the use of rigorous evidence in planning, implementing, and assessing social service investments. The Social Innovation Fund (SIF), a program of the Corporation for National and Community Service, adopted a public-private partnership approach to tiered…

Card and Giuliano conducted a regression discontinuity study in a large Florida school district to investigate the magnitude of academic benefits of the district's gifted program. They found that for children identified as gifted through an intelligence test, the program provided few or no benefits. But children who were admitted to the gifted…

This report examines the range of factors that might influence the decision by social care professionals on the use of boarding schools as an intervention option for Children in Need (CiN) or children on a Child Protection Plan (CPP). Attempts to conduct a randomised controlled trial (RCT) failed to recruit participants. Initially, failure to…

The report of the national response to intervention (RTI) evaluation study, conducted during 2011-2012, was released in November 2015. Anyone who has read the lengthy report can attest to its complexity and the design used in the study. Both these factors can influence the interpretation of the results from this evaluation. In this commentary, we…

The purpose of this investigation was to explore whether a difference existed between the effectiveness of paper-based format and tablet computer-based format Social Story interventions on frequency of undesired behaviors. An adapted alternating treatment design was implemented with four children with autism spectrum disorder (ASD). Data regarding…

This study reports on Residency I, the first semester of a yearlong residency that utilizes problem-based learning scenarios, combined with field work, that covers both content and context and is meant to positively impact teacher candidates' self-efficacy as well as their actual efficacy as measured by scores on the edTPA. This quantitative…

Upward Bound (UB) was one of the original federal "Great Society" programs of the 1960s and remains, fifty years later, the single largest college access program in the country. Recently, Congress has reduced funding and considered eliminating the program because of federal budget pressures and because the first analysis of the only…

This paper reviews literature on the rationale, challenges, and recommendations for choosing a nonequivalent comparison (NEC) group design when evaluating intervention effects. After reviewing frequently addressed threats to validity, the paper describes recommendations for strengthening the research design and how the recommendations were…

This synthesis paper summarizes research literature addressing challenging behaviours in children and youth with autism spectrum disorders and developmental disabilities in school settings. We conducted a comprehensive literature review to identify relevant peer-reviewed articles published between the years 2000 and 2011. The methodological…

In order to better assist practitioners and better serve persons with autism spectrum disorders (ASD) and their families, it is vital for professionals to systematically evaluate the existing body of literature and synthesize its scientific evidence, so that the efficacy of research can be translated to evidence-based practices (EBPs) (Wheeler,…

Purpose: The purpose of this paper is to explore the effectiveness of action design research (ADR), a combination of action research and design science research, when conducting research where both practical relevance and academic rigor are required. Design/methodology/approach: This paper presents ADR in action in order to motivate its use when…

The science-to-service problem continues to taunt the field of education (Fixsen, Blasé, Naoom, & Wallace, 2009). As an academic discipline, the field requires knowledge generation that adds to or deepens theoretical understandings. As a profession, knowledge generation that solves local problems and supports continuous improvement is…
