"Educational Explanations" is a comprehensive study of the main philosophical questions that confront empirical educational researchers. The book outlines the sense in which empirical educational research pursues truth and sets out and defends an account of its task as the offering of explanations for the many educational problems that…

Many students with learning disabilities (LD) do not master basic reading skills, which affects later reading fluency and reading comprehension development. Single-case experimental design (SCED) research yields unique opportunities to better understand which aspects of a basic reading intervention are effective with a particular student,…

Single-case experimental designs (SCEDs) are a useful tool for evaluating the effects of interventions at an individual level and can play an important role in the development and validation of evidence-based practices. Historically, researchers relied on visual analysis of SCED data and eschewed statistical approaches. Although researchers…

In this case study, I provide the methodologic approaches I used to investigate four in-service biology teachers' perspectives when using science instruction to address racial stereotypes within secondary science education. This case study provides practical advice for novice qualitative researchers who wish to conduct and design an intervention…

In science in general and in the context of single-case experimental designs, replication of the effects of the intervention within and/or across participants or experiments is crucial for establishing causality and for assessing the generality of the intervention effect. Specific developments and proposals for assessing whether an effect has been…

The major aim of this manuscript is to bring together two important topics that have recently received much attention in child and adolescent research, albeit separately from each other: single-case experimental designs and statistical mediation analysis. Single-case experimental designs (SCEDs) are increasingly recognized as a valuable…

Single-case research methods provide the basis for evaluating effective instructional approaches in special education. The purpose of this article is to provide special educators an overview of single-case research methods, with an emphasis on how these designs are used to establish whether an instructional practice relates to improved learner…

Literacy intervention research tests our best ideas about instruction and forges a pathway forward toward deeper and more nuanced understandings of how children think, communicate, and learn. This chapter describes the components of the development of literacy interventions, explaining how to construct and evaluate each component in sequence to…

The use of single-case effect sizes (SCESs) has increased in the intervention literature. Meta-analyses based on single-case data have also increased in popularity. However, few researchers who have adopted these metrics have provided an adequate rationale for their selection. We review several important statistical assumptions that should be…

The central roles of science in the field of remedial and special education are to (a) identify basic laws of nature and (b) apply those laws in the design of practices that achieve socially valued outcomes. The scientific process is designed to allow demonstration of specific (typically positive) outcomes, and to assist in the attribution of…

Purpose: Single-case experimental designs are widely used to study interventions for communication disorders. Traditionally, single-case experiments follow a response-guided approach, where design decisions during the study are based on participants' observed patterns of behavior. However, this approach has been criticized for its high rate of…

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…

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 article offers 10 guidelines for conducting international group work research. These guidelines include the importance of establishing relationships, conducting a needs assessment, co-constructing the research questions/design, determining the approach, choosing culturally relevant instruments, choosing culturally responsive group…

Research in early intervention/early childhood special education (EI/ECSE) is focused on identifying effective practices related to positive outcomes for young children with disabilities and their families. Individual responses to evidence-based practices are often variable, and non-responders are common. Single case research (SCR) might be…
