The purpose of this study is to present a set of empirically derived effect size distributions in order to provide field-based benchmarks for assessing the relative effects of interventions aimed at reducing challenging behavior or increasing engagement for young children with and without disabilities. We synthesized 192 single-case designs that…

Single-case designs substantiate the effectiveness of interventions for people with disabilities and other populations through the repeated measurement of behavior over time. Consequently, employing accurate and reliable systems of measurement is critical to the validity of single-case designs. Much of the data in single-case research are…

The overarching purpose of this article is to provide an introduction to the use of rigorous single-case research designs (SCRDs) in special education and related fields. Authors first discuss basic design types and research questions that can be answered with SCRDs, examine threats to internal validity and potential ways to control for and detect…

Single-case design has a long history of use for assessing intervention effectiveness for children with disabilities. Although these designs have been widely employed for more than 50 years, recent years have been especially dynamic in terms of growth in the use of single-case design and application of standards designed to improve the validity…

Despite the case study research method has been widely adopted in qualitative research, few scholarly articles addressed the comprehensive guidance on the use of embedded case study research design. This paper aims to contribute to the literature by demonstrating the use of embedded case study research design in qualitative research. A pseudo case…

Case study has been one of the most often used qualitative research methodologies in the field of education at all levels -- from preschool to adult. Yet the number of available resources for case study researchers--be they emerging or experienced--is still limited. This paper will review the definition of the case study method as well as some of…

Multitiered systems of support provide a framework for matching the needs of a struggling student with an appropriate intervention. Experimental evaluations of tiered support systems in grade schools have been conducted for decades but have been less frequently examined in early childhood contexts. A recent meta-analysis of multitiered systems of…

In this article, we call for Canadian digital literacies researchers to invest in designs and research methods that centralise in-the-moment insights, embrace complexity, and that are informed by a deep commitment to authentic, ethical reciprocity that serves the communities in which our work is placed. We present three cases that offer multiple…

Nowadays, technologies play a key role in educational research processes, especially in the context of complex designs or integrative perspectives (qualitative and quantitative). Affordances provided by new tools and technological devices are constantly impacting the way educational research is carried out. Consequently, this growing importance…

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…

This research aims to make a methodological contribution to the mixed methods literature by investigating the value-added of empirical studies that are explicitly framed with the purpose of interrogating divergent findings. Case studies introduce the role philosophical paradigms can play in reconciliation process and reveal the potential to…

In this article we propose a case selection strategy for comparative studies of school improvement. The strategy is based on two assumptions. First, we emphasize the importance of a strategic selection of cases (schools), which allows systematic comparisons between successful and failing schools. We claim that cases should be selected on the…

The purpose of this case is to understand the process of a case study research as it was employed to investigate a government-initiated curriculum reform in secondary schools. The policy to practice aspect of school education has long been a contested field. Certainly, previous research has highlighted the problematic nature of implementing policy…

Reflecting recent knowledge and developments in the field, this very practical, easy-to-use guide emphasizes learning how to do case study research--from the first step of deciding whether a case study is the way to go to the last step of verifying and confirming findings before disseminating them. The authors show students how to determine an…
