This study aims to introduce network meta-analysis (NMA) to provide educational researchers with an extended view of the reviewing educational research. Meta-analytic methods have been widely used in educational research reviews. However, weaknesses have emerged in the multi-group comparison analysis of educational studies where different…

Experimental studies are often employed to test the effectiveness of teaching innovations such as new pedagogy, curriculum, or learning resources. This article offers guidance on good practice in developing research designs, and in drawing conclusions from published reports. Random control trials potentially support the use of statistical…

Comparison studies conducted to determine which instructional interventions are most efficient for teaching discrete behaviors to individuals with disabilities are potentially valuable, although some threats to internal validity may be more likely in these studies. Studies included in this review typically met common internal validity standards,…

Background: Over the past 20 years, much has been written about the merits and limitations of matching methods, particularly propensity score matching (see, e.g., Stuart, 2010 for a review of matching approaches), and the myriad ways matching can be implemented to identify a comparison group that is similar to the treatment group on observable…

We conducted a systematic literature review of 111 empirical studies published between 1969 and 2018. We found that research does not exponentially grow in comparison to research on higher education or leadership; empirical research emerging in the 1980s does not completely replace non-empirical inquiry. Studies from English-speaking authors…

More aggregate data on school performance is available than ever before, opening up new possibilities for applied researchers interested in assessing the effectiveness of school-level interventions quickly and at a relatively low cost by implementing comparative interrupted times series (CITS) designs. We examine the extent to which effect…

The aim of this article is to provide practitioners and other nonresearchers a basic understanding of research designs to aid in appropriately interpreting and applying research findings in special education. Research design provides the blueprint for conducting a research study and shapes what kind of knowledge is generated by the study. We…

The question of why we need to think about how we research race demands a conceptualization of race that captures both its social construction and its temporal evolution. We need both an understanding of race and clarity about how we talk about it in our design and conduct of research, and in how we interpret and apply it in our findings. As a…

The purpose of this article is to provide a critique of the main concepts of qualitative and quantitative methodologies for conducting research. It is written expressly for the novice researcher in an attempt to clarify the major misconceptions and misunderstandings concerning the qualitative-quantitative research polarities. This article will not…

Short comparative interrupted times series (CITS) designs are increasingly being used in education research to assess the effectiveness of school-level interventions. These designs can be implemented relatively inexpensively, often drawing on publicly available data on aggregate school performance. However, the validity of this approach hinges on…

The What Works Clearinghouse (WWC) is an initiative of the U.S. Department of Education's Institute of Education Sciences (IES), which was established under the Education Sciences Reform Act of 2002. It is an important part of IES's strategy to use rigorous and relevant research, evaluation, and statistics to improve the nation's education system.…

How well doctoral students in special education are prepared to evaluate research as evidence-based practice (EBP) is likely to impact their careers, as well as the teachers they will train. In developing a method for evaluating the readiness of small cohort groups of doctoral students to apply a research-based model of EBP, an instrument and…

The purpose of this study was to compare the results of a regression discontinuity design (RDD) with those of an experimental design of a tiered vocabulary intervention for children at risk for reading disability to determine RDD's feasibility as a research methodology for this type of study. Researchers reanalyzed an archival dataset of a…

In this article, the "Council for Exceptional Children (CEC)" presents Standards for Evidence-Based Practices in Special Education. The statement presents an approach for categorizing the evidence base of practices in special education. The quality indicators and the criteria for categorizing the evidence base of special education…

The purpose of this paper is to describe best practices in designing and implementing strong quasi-experimental designs (QED) when assessing the effectiveness of policies, programs or practices. The paper first discusses the issues researchers face when choosing to conduct a QED, as opposed to a more rigorous randomized controlled trial design.…
