Despite the rapid development of the field of Mobile-assisted Language Learning (MALL), research synthesis and systematic meta-analyses on MALL are still lacking. It remains unclear how effective mobile devices are for language learning under different conditions. Review studies on the overall effectiveness of the latest smart mobile devices are…

This paper presents a critical analysis, from the point of view of a statistician, of the methodology used by Hattie in "Visible Learning," and explains why it must absolutely be called pseudoscience. We first discuss what appears to be the intentions of Hattie's approach. Then we describe the major mistakes in "Visible…

Learning Forward undertakes periodic updates to the Standards of Learning because educator needs, expertise in the field, and research related to professional learning are continually evolving. In addition, evidence and data are critical to implementing and documenting the results-based professional learning that policy and accountability systems…

Since the standards-based education movement began in the early 1990s, mathematics education reformers have developed and evaluated many interventions to support students in mastering more rigorous content. We conducted a systematic review and meta-analysis of U.S. PreK-12 mathematics intervention effects from 1991 to 2017 to study sources of…

This second-order meta-analysis (i.e., systematic quantitative synthesis of individual meta-analyses) summarises how the use of technology affects learning (achievement outcomes) in three different educational settings: in-class, online learning and blended learning. Comprehensive literature searches identified 915 potentially relevant…

We propose a new framework for conceptualizing measures of instructed second language (L2) pronunciation performance according to three sets of parameters: (a) the constructs (focused on global vs. specific aspects of pronunciation), (b) the scoring method (human raters vs. acoustic analyses), and (c) the type of knowledge elicited (controlled vs.…

"Visible Learning Insights" presents a fascinating 'inside view' of the ground-breaking research of John Hattie. Together, the authors John Hattie and Klaus Zierer embark on a mission to build on the internationally renowned work and combine the power and authority of the research with the real 'coal face' experience of schools. Offering…

This meta-analysis has two objectives: (a) to address the main effects of learning cycle models on students' success in science; and (b) to address potential moderators of the effect of LC models. This meta-analysis was conducted by calculating the effect size of 75 studies, including theses and journal papers associated with the implementation of…

This aim of this study is to determine the effect of the TPR method on students' vocabulary learning and the factors affecting the effectiveness of this method by combining the findings obtained from both qualitative and quantitative studies. For this purpose, a primary study with 13 quantitative and 7 qualitative findings was included in this…

Lesson Study is a Japanese approach to teacher development borrowed by American researchers in the late 1990s seeking to break from top-down, "best practice" approaches. Two decades later, Lesson Study has gained a strong foothold in American policy circles. Seeking to contribute to the growing research base, this article looks deeper…

The results of tracer studies on the approach of Jelajah Alam Sekitar (JAS) or environment exploring learning has been detected is used in eight provinces in Indonesia and studied in the learning begin primary school to college. Then, how the effectiveness of the implementation of the JAS approach in improving the learning process. This study uses…

While reflection has been a common tool for examining the development of teaching and learning practices in the classroom, its use in a language learning setting is still peripheral and minimal. To understand the potential of reflection in supporting language learning, this study presents a qualitative meta-synthesis on selected studies. These…

This meta-analysis analyzed 39 studies that met the inclusion criteria for employment-related interventions for individuals with developmental disabilities. Each experiment included in this analysis either met or met with reservations all of the basic design standards (Kratochwill et al. 2010, 2013). Tau-U effect sizes were calculated for each…
