Second language (L2) researchers often have to develop or change the instruments they use to measure numerous constructs (Norris & Ortega, 2012). Given the prevalence of researcher-developed and -adapted data collection instruments, and given the profound effect instrumentation can have on results, thorough reporting of instrumentation is…

The current study examined the use of video modeling (VM)-based interventions to reduce the challenging behaviors of students with emotional or behavioral disorders. Each study was evaluated using Council for Exceptional Children's (CEC's) quality indicators for evidence-based practices. In addition, study effects were calculated along the three…

Although note taking is frequently described as an important skill for postsecondary success, there have been few note-taking intervention studies involving multiple sessions spanning more than one week. In a systematic search, we identified seven peer-reviewed articles reporting 10 intervention studies published from 1990-2014. The only…

Mathematics education has benefited from qualitative methodological approaches over the past 40 years across diverse topics. Although the number, type, and quality of qualitative research studies in mathematics education has changed, little is known about how a collective body of qualitative research findings contributes to our understanding of a…

This systematic review has analyzed 53 English language studies that assessed and compared peoples' self-reported and demonstrated information literacy (IL) skills. The objective was to collect empirical evidence on the existence of Dunning-Kruger Effect in the area of information literacy. The findings clearly show that this theory works in this…

An increase has occurred in the number of students identified as having high functioning autism (HFA), who are being served in the regular education setting with their non-disabled peers. Many of these students have difficulty with academic and social expectations in this setting, and a minimal amount of information is available to educators…

Good practice in primary research has evolved over many decades of research in applied linguistics to counter human fallibility and biases. Surprisingly, perhaps, synthesising such research in an entire field has only recently started to develop its own methodologies and recommendations. This paper outlines some of the issues involved, especially…

Community schools are receiving increased attention in Pennsylvania and across the country as policymakers and practitioners strive to address the effects of poverty on academic performance, and provide more comprehensive supports for traditionally-underserved populations. While many advocates and education leaders tout the promise of community…

In this note, we explain how the method proposed by Hartung and Knapp provides a compromise between conventional meta-analysis methodology and "unconstrained averaging", as used by the Particle Data Group.

Forest plots provide an effective means of presenting a wealth of information in a single graphic. Whether used to illustrate multiple results in a single study or the cumulative knowledge of an entire field, forest plots have become an accepted and generally understood way of presenting many estimates simultaneously. This article explores…

This autoethnographic research project examines the transformational learning of a transracial adoptive adult mother and daughter through the lens of postcolonialism. As collaborative researchers, adult adoptee and adoptive mother, examine this lifelong learning experience through critical self-reflection, qualitative meta-analysis, and…

In this meta-analysis, I have reviewed published and unpublished research on single-track, year-round education's effect on science and social studies achievement, 2001-2016. Of 30 studies that met inclusion criteria and had data from which an effect size estimate could be calculated, 7 reported science outcomes (18 effect size estimates) or…

Purpose: Despite the apparent primacy of syntactic deficits, children with developmental language disorder (DLD) often also evidence lexical impairments. In particular, it has been argued that this population have difficulty forming lexical representations that are detailed enough to support effective spoken word processing. In order to better…

Despite the multiple meta-analyses documenting the association between socioeconomic status (SES) and achievement, none have examined this question outside of English-speaking industrialized countries. This study is the first meta-analytic effort, to the best of our knowledge, to focus on developing countries. Based on 49 empirical studies…

This study aimed at performing content analysis and meta-analysis on dissertations related to brain-based learning in science education to find out the general trend and tendency of brain-based learning in science education and find out the effect of such studies on achievement and attitude of learners with the ultimate aim of raising awareness…
