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…

Adolescent clinical and subclinical depression has a significant negative impact on adolescents well being, school performance and consequently produces maladaptive outcomes in terms of subsequent education and occupational functioning. This research is a part of a larger research project with a focus on clinical and subclinical depression during…

Researchers in the single-case design tradition have debated the size and importance of the observed autocorrelations in those designs. All of the past estimates of the autocorrelation in that literature have taken the observed autocorrelation estimates as the data to be used in the debate. However, estimates of the autocorrelation are subject to…

This article presents 3 standardized effect size measures to use when sharing results of an analysis of mediation of treatment effects for cluster-randomized trials. The authors discuss 3 examples of mediation analysis (upper-level mediation, cross-level mediation, and cross-level mediation with a contextual effect) with demonstration of the…

Questions regarding the generalizability of results from educational experiments have been at the forefront of methods development over the past five years. This work has focused on methods for estimating the effect of an intervention in a well-defined inference population (e.g., Tipton, 2013; O'Muircheartaigh and Hedges, 2014); methods for…

Evidence-based practices (EBPs) are supported as generally effective for populations of learners by bodies of high-quality and experimental research and, when aligned with stakeholder values and practical needs, should be prioritized for implementation. However, evidence-based practices are not currently available for all learner types in all…

A multilevel meta-analysis can combine the results of several single-subject experimental design studies. However, the estimated effects are biased if the effect sizes are standardized and the number of measurement occasions is small. In this study, the authors investigated 4 approaches to correct for this bias. First, the standardized effect…

It is generally acknowledged that novice researchers may not be adequately prepared to engage in/with research and that an increasingly widening divide exists between researchers and teachers, and therefore between research and practice. To explore this gap, this paper addresses ten of the most popular misconceptions novice researchers hold in…

This review examines the doctoral research in Turkey completed between 2010 and 2014 in the area of English language teaching and learning. All of the dissertations (N = 137) indexed in the National Theses Database have been included in order to analyze dissertations' subject areas, research paradigms/techniques, and research contexts as well as…

Many current national and institutional education policies address the issue of raising participation amongst young people and enhancing employability after leaving school or university. What sort of information are these policies built on? This paper compares national information systems from the last three decades across Europe that gather…

This study investigated whether children with disabilities are excluded from mainstream child development research. Fifteen per cent of 533 articles from "Child Development" and "Developmental Psychology" (1996-2010) were randomly selected. The exclusion rate was 89.9% when no mention of participants with disabilities was…

The goal of this chapter is to recommend quality criteria to guide evaluators' selections of sampling designs when mixing approaches. First, we contextualize our discussion of quality criteria and sampling designs by discussing the concept of interpretive consistency and how it impacts sampling decisions. Embedded in this discussion are…

The purpose of this study is to carry out a content analysis about the studies on teachers' professional development and to determine the tendencies in these studies. Within this scope, 60 studies that were registered to Turkish National Thesis Centre and ProQuest database between the years 2005-2015 were examined. Of the 60 studies, 37 of them…

Child abuse has profound immediate and long-term effects on a child's development. The long-term impact of abuse of a child can be seen in higher rates of psychiatric disorders, increased rates of substance abuse and relationship difficulties [Springer, K. W., Sheridan, J., Kuo, D., & Carnes, M. (2003). "The long-term health outcomes of…

There is a long-standing debate as to whether nonexperimental estimators of causal effects of social programs can overcome selection bias. Most existing reviews either are inconclusive or point to significant selection biases in nonexperimental studies. However, many of the reviews, the so-called "between-studies," do not make direct…
