Randomization of large number of participants to different treatment groups is often not a feasible or preferable way to answer questions of immediate interest to professional practice. Single case designs (SCDs) are a class of research designs that are experimental in nature but require only a few participants, all of whom receive the…

The last decade has witnessed resurgence in the interest in studying the causal mechanisms linking causes and effects. This article games through the methodological consequences that adopting a systems understanding of mechanisms has for what types of cases we should select when using in-depth case study methods like process tracing. The article…

Single-case data are frequently used in school psychology. In research, single-case designs allow experimenters to provide rigorous demonstrations of treatment effects on a smaller scale and with more precise measurement than traditional group experimental design. In practice, single-case data are used to evaluate the effects of school-based…

Purpose: The purpose of this paper is to focus on the methodological challenges in the design and implementation of an emotionally sensitive topic involving research with adolescents based on a study evaluating the experiences of adolescents and families facing a diagnosis of maternal cancer. Design/methodology/approach: This conceptual paper…

Education experiments frequently assign students to treatment or control conditions within schools. Longitudinal components added in these studies (e.g., students followed over time) allow researchers to assess treatment effects in average rates of change (e.g., linear or quadratic). We provide methods for a priori power analysis in three-level…

The problem of assessing whether experimental results can be replicated is becoming increasingly important in many areas of science. It is often assumed that assessing replication is straightforward: All one needs to do is repeat the study and see whether the results of the original and replication studies agree. This article shows that the…

A systematic review explored the evidence base of literacy intervention studies that examined the early years of schooling (preschool through first grade) of participants who were d/Deaf or hard of hearing (d/Dhh). Specific inclusion criteria were used to select single-case design (SCD) studies published in peer-reviewed journals between 2004 and…

Over the past 15 years, the education research community has advocated for rigorous research designs that support causal inferences, for research that provides more generalizable results across settings, and for the value of research-practice partnerships that inform the design of local programs and policies. We propose the multi-cohort,…

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…

The scholarship of practice entails the use of findings of empirical research to guide the development of institutional policy and practice. Accordingly, engagement in the scholarship of practice by enrollment management (EM) officers precludes them from "shooting from the hip" or trial-and-error forms of professional action. Engagement…

Most agricultural research organizations strive to address societal challenges and contribute to positive societal impacts. Fulfilling this ambition involves embedding a culture of impact in organizational culture, which, in our view, entails three main elements: understanding the role of the research community in contributing to impacts over the…

This paper discusses some of the recurrent issues which the authors have noticed in educational research. These might be concerned with the nature of social science research, such as its representation of the reality of student learning, the role for replication studies, and the tolerance for disagreements. There are also issues related to the…

An engaging, cross-disciplinary guide to research methodology "Practical Research: Planning and Design" is a do-it-yourself, how-to manual for planning and conducting research. Suitable for a wide variety of courses in basic research methodology, the book uses a conversational tone, step-by-step instructions, and practical suggestions to…

The problem of assessing whether experimental results can be replicated is becoming increasingly important in many areas of science. It is often assumed that assessing replication is straightforward: All one needs to do is repeat the study and see whether the results of the original and replication studies agree. This article shows that the…

The field of comparative and international education has followed methodological trends in social science research since the merging of the "twin" field after World War II. With increase in the use of mixed methods research about three decades ago, comparative and international education journals and scholars have worked rigorously to be…
