Research Findings: The early childhood years are critical in developing early mathematics skills, but the opportunities one has to learn mathematics tend to be limited, preventing the development of significant mathematics learning. By conducting a meta-analysis of 29 experimental and quasi-experimental studies that have been published since 2000,…

Stress research increasingly emphasizes the role of appraisal in determining which events are perceived as stressful. The Classroom Appraisal of Resources and Demands (CARD) was developed to measure teachers' appraisals of their classroom demands and resources in order to assess their risk for experiencing occupational stress. The present purposes…

This chapter summarizes a set of research studies that focus on high school course offerings, takings, and effects. Improving high school experiences and having students graduate from high school ready for college are national priorities under President Obama's Race to the Top initiative. Doing so by expanding access to advanced courses dates back…

The United States will lose its ability to compete in the global knowledge economy if its educational system is not significantly improved. It now ranks 13th in college graduation rates. In a recent 24-country Survey of Adult Skills, the U.S. ranked 16th in literary proficiency and 21st in numeracy proficiency. Without an intervention, the United…

To determine the issue of whether there were any significant differences between the groups including Iran ISI, Iran non- ISI, and native authors in binary comparisons as for employing interactional markers, the present study was conducted. To collect the data, 90 "method sections" of English medical research articles within Iranian ISI,…

The prevalence of autism is increasing globally. While most of the published works are done in the Western and European countries, the trend in autism research is shifting towards the Asian continent recently. In this review, we aimed to highlight the current prevalence, diagnosis, treatment and research on Autism Spectrum Disorders (ASD) in…

Drawing on interactionist and socio-cultural theories, tools provided in computer-mediated communication (CMC) environments have long been considered able to create an environment that shares many communicative features with face-to-face communication. Over the past two decades, researchers have employed a variety of strategies to examine the…

This study's aim is to measure the effect sizes of the quantitative studies that examined the effectiveness of brain-based learning on students' academic achievement and to examine with the meta-analytical method if there is a significant difference in effect in terms of the factors of education level, subject matter, sampling size, and the…

This research aimed to examine the effect of a problem-based learning approach in comparison to traditional learning approaches. In this context, the question "What is the effect size of problem-based learning on students' attitudes?" was tried to be answered. Among 190 studies made in national and international field between the…

This paper serves several purposes. First and foremost, it is devoted to developing a better understanding of the effectiveness of blended learning (BL) in higher education. This is achieved through a meta-analysis of a sub-collection of comparative studies of BL and classroom instruction (CI) from a larger systematic review of technology…

Meta-analyses are syntheses of effect-size estimates obtained from a collection of studies to summarize a particular field or topic (Hedges, 1992; Lipsey & Wilson, 2001). These reviews are used to integrate knowledge that can inform both scientific inquiry and public policy, therefore it is important to ensure that the estimates of the effect…

The objective of this research was to conduct a meta-analysis to examine existing research studies on video modeling as an effective teaching tool for children and adolescents diagnosed with Autism Spectrum Disorder (ASD). Study eligibility criteria included (a) single case research design using multiple baselines, alternating treatment designs,…

Meta-analytic research is an effective method for synthesizing existing research and for informing practice and policy. Hattie (2009) suggested that meta-analytic procedures could be employed to existing meta-analyses to create a mega-analysis. The current mega-analysis examined a sample of 47 meta-analyses according to the "School…

This article reports a meta-analysis of studies that investigated the relative effectiveness of comprehension-based instruction (CBI) and production-based instruction (PBI). The meta-analysis only included studies that featured a direct comparison of CBI and PBI in order to ensure methodological and statistical robustness. A total of 35 research…

In this study, the aim was to combine the results obtained in independent studies aiming to determine the effectiveness of material use. The main question of the study is: "Does material use in classroom instruction improve students' academic achievements?" To answer this question, the meta-analysis method was employed.…
