Meaningfully synthesizing single case experimental data from intervention studies comprised of individuals with low incidence conditions and generating effect size estimates remains challenging. Seven effect size metrics were compared for single case design (SCD) data focused on teaching speech generating device use to individuals with…

There is a diverse literature that explores the relationship between youth, music, and mental health, with few attempts at systematic synthesis. This critical interpretive review included 33 studies published between 2000 and 2012 investigating the relationship between music and the mental health of young people, particularly targeting depression.…

This conversation explores emerging debates concerning teaching to and about marginalized populations often left out of "representative" data sets. Based on our experiences studying, teaching, and belonging to some of these unrepresented populations, we outline some strategies sociologists may use to transform the limitations of data…

The article by Davis, Engberg, Epple, Sieg, and Zimmer (2010) represents one of the recent research efforts from economists in evaluating the impact of gifted programs. It can serve as a worked example of the implementation of the regression discontinuity (RD) design method in gifted education research. In this commentary, we first illustrate the…

Over many decades, educators have developed countless interventions and theories about how to create lasting change. Implementation research is the study of these efforts with a set of basic questions: What are we doing? Is it working? For whom? Where? When? How? And, Why? In other words, implementation research is an endeavor to understand if and…

This document provides step-by-step instructions on how to complete the Study Review Guide (SRG, Version S3, V2) for single-case designs (SCDs). Reviewers will complete an SRG for every What Works Clearinghouse (WWC) review. A completed SRG should be a reviewer's independent assessment of the study, relative to the criteria specified in the review…

This document offers a national picture of selected segments of the early care and education (ECE) market by describing how important attributes of the supply of and the demand for center-based care relate to each other. The document also provides a methodological guide for using newly available data from the National Survey of Early Care and…

In a meta-analysis, it is important to specify a model that adequately describes the effect-size distribution of the underlying population of studies. The conventional normal fixed-effect and normal random-effects models assume a normal effect-size population distribution, conditionally on parameters and covariates. For estimating the mean overall…

The purpose of this study is to illustrate the multilevel meta-analysis of results from single-subject experimental designs of different types, including AB phase designs, multiple-baseline designs, ABAB reversal designs, and alternating treatment designs. Current methodological work on the meta-analysis of single-subject experimental designs…

Outdoor adventure education (OAE) has a long history of being credited with the personal and social development (PSD) of its participants. PSD is notoriously difficult to measure quantitatively, yet stakeholders demand statistical evidence that given approaches to eliciting PSD are effective in their methods. Rightly or wrongly, many stakeholders…

In the current study, we reinforced tacts with positive qualifying autoclitics for reading and evaluated the subsequent effect on the allocation of reading behavior. Participants were four typically developing children between 9 and 12 years of age whose primary language was Arabic. We exposed each participant to pre- and posttreatment sessions to…

Recent publications have drawn attention to the idea of utilizing prior information about the correlation structure to improve statistical power in cluster randomized experiments. Because power in cluster randomized designs is a function of many different parameters, it has been difficult for applied researchers to discern a simple rule explaining…

The Third Edition of Miles & Huberman's classic research methods text is updated and streamlined by Johnny Saldaña, author of "The Coding Manual for Qualitative Researchers." Several of the data display strategies from previous editions are now presented in re-envisioned and reorganized formats to enhance reader accessibility and…

Thanks to remarkable methodological and statistical advances in recent years, single-case design (SCD) research has become a viable and often essential option for researchers in applied psychology, education, and related fields. This text is a compendium of information and tools for researchers considering SCD research, a methodology in which one…

The transition of the Australian paramedic discipline from vocation education and training to the higher education sector has seen a sharp rise in interest in near-peer teaching (NPT). The objective of this study was to examine satisfaction levels of NPT over one academic semester among undergraduate paramedic students. A repeated measured design…
