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…

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…

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…

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…

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…

In response to questions in which a "wh"-term interacts with a universal quantifier in object position, such as "Who picked every toy?," children as old as 5 years of age often provide a list, pairing toys with the people who picked each of them. This response pattern is unexpected, it has been claimed, because children appear…

The testing effect is a well-known concept referring to gains in learning and retention that can occur when students take a practice test on studied material before taking a final test on the same material. Research demonstrates that students who take practice tests often outperform students in nontesting learning conditions such as restudying,…

Across the disciplines of economics, political science, public policy, and now, education, the randomized controlled trial (RCT) is the preferred methodology for establishing causal inference about program impacts. But randomized experiments are not always feasible because of ethical, political, and/or practical considerations, so non-experimental…

Survey research is prevalent among many professional fields. Both cost effective and time efficient, this method of research is commonly used for the purposes of gaining insight into the attitudes, thoughts, and opinions of populations. Additionally, because there are several types of survey research designs and data collection instruments, the…

Background/Context: Educational and societal phenomena can converge to draw attention to a new focus, such as ELs and STEM, and then trigger new research interests. A funding program can play a critical role in shaping these new research interests by prioritizing specific research topics and designs or by requiring particular specializations of…

E-learning research is plenty of difficulties, as also research in education is. Usually, the high number of features involved in e-learning processes complicates and masks the identification and isolation of the factors which cause the expected benefits, when they exist. At the same time, a bunch of threats are ready to weaken the validity of the…
