Extensive reading has been continuously studied as a promising instructional method for improving students' language proficiency, including reading proficiency, vocabulary acquisition, and grammar awareness. The present study is a meta-analysis, which synthesized the data of 21 empirical studies (N = 1268). It was designed to explore whether…

Digital games (e.g., video games or computer games) have been reported as an effective educational method that can improve students' motivation and performance in mathematics education. This meta-analysis study (a) investigates the current trend of digital game-based learning (DGBL) by reviewing the research studies on the use of DGBL for…

In this paper the author introduces a very practical model to guide school leaders/managers into supporting parental involvement and engagement in their schools. The model is called the Dual Navigation Approach (DNA). This rubric is based on six meta-analyses that he conducted over the last fifteen years. What is presented therefore is a…

Service-learning (SL) has been validated throughout many studies as a productive experience to encourage relationship building between institutions and the community with measurable results. The aim of this meta-synthesis is to identify the underlying principles that promote SL in higher education with English Language Learners (ELLs) as a…

This paper focuses on a fairly new motivational technique, the so-called Gamification, which consists of introducing game mechanics in non-game environments to promote motivation and engagement. By the turn of the 21rst century, Gamification took off in the business field and soon after became an attractive concept for researchers and…

This meta-analysis investigated the overall effects of glossing on L2 vocabulary learning from reading and the influence of potential moderator variables: gloss format (type, language, mode) and text and learner characteristics. A total of 359 effect sizes from 42 studies (N = 3802) meeting the inclusion criteria were meta-analyzed. The results…

Captioned video is widely used to enhance second language (L2) learners' exposure to oral input beyond the classroom setting, and captioning has been found to provide an instantaneous, useful visual aid for parsing and understanding L2 oral discourse. Nevertheless, a meta-analysis has shown that captioning exerts a selective effect on L2 learners…

The "Q" test is regularly used in meta-analysis to examine variation in effect sizes. However, the assumptions of "Q" are unlikely to be satisfied in practice prompting methodological researchers to conduct computer simulation studies examining its statistical properties. Narrative summaries of this literature are available but…

As the link between maternal obesity and risk of autism among offspring is unclear, the present study assessed this association. A systematic search of an electronic database was performed to identify observational studies that examined the association between maternal obesity and autism. The outcome measures were odds ratios comparing offspring…

Infants start learning words, the building blocks of language, at least by 6 months. To do so, they must be able to extract the phonological form of words from running speech. A rich literature has investigated this process, termed word segmentation. We addressed the fundamental question of how infants of different ages segment words from their…

It is no surprise to educators and prevention specialists that for more than two decades, the majority of evaluation studies of individual psychosocial prevention strategies not only in substance-abuse prevention but in all of social science research have failed to find sustained positive outcomes (Feldman, 1983; Kreft & Brown, 1998). Many…

Peer review of teaching (PRT) is one of the various assessment methods employed to assess teaching effectiveness. The current meta-synthesis aims to summarize the faculty perceived barriers and attitudes toward PRT process. A systematic search was done across a range of databases, with 26 studies being found acceptable for data extraction. Because…

Clinical Question: Would individuals with acquired apraxia of speech (AOS) demonstrate greater improvements for speech production with an articulatory kinematic approach or a rate/rhythm approach? Method: EBP Intervention Comparison Review. Study Sources: ASHA journal, Google Scholar, PubMed, CINAHL Plus with Full Text, Web of Science, Ovid, and…

This meta-analytic study compared the effect of peer-led learning versus non peer-led learning on students' cognitive achievement in post-secondary education. Twenty-eight studies published in English from six countries between 1993 and 2017 were identified and used in the analysis. Result of the analysis on the random-effect model showed a…

Over the years, persistently low achievement levels have led scholars to question whether reading skill development is different for deaf readers. Research findings suggest that in order for deaf students to become proficient readers, they must master the same fundamental abilities that are well established for hearing learners, regardless of the…
