In this study, it is aimed to determine the effect of visualization on mathematics achievement in the thesis studies conducted in Turkey. In this context, the findings obtained from individual studies are combined via meta-analysis. For this purpose, Council of Higher Education (CoHE) National Thesis Center database was thoroughly scanned by using…

Disability simulation is an educational approach to modify attitudes and behaviors toward persons with disabilities by allowing participants to experience simulated life activities of individuals with disabilities. Despite the controversy regarding the effectiveness of disability simulations and its potential counterproductive effects, however,…

Much of the evidential basis for recent policy decisions is grounded in effect size: the standardised mean difference in outcome scores between a study's intervention and comparison groups. This is interpreted as measuring educational influence, importance or effectiveness of the intervention. This article shows this is a category error at two…

The purpose of this review was to conduct a meta-analysis of 25 years of mathematics interventions for students with mathematics difficulty or disability in Grades 4 through 12. A search of the literature yielded 25 studies that met the inclusion criteria. Studies were coded to extract important study information (e.g., participant information,…

In this study, through a meta-analysis of 20 studies, it is aimed to compare the effectiveness of various forms of learning methods including creativity based learning, problem based learning, and differentiated instruction on creativity in terms of the academic achievement of students and to find out other study characteristics, related to the…

This meta-analysis is the first to provide a quantitative synthesis of empirical evaluations of mathematical intervention programs implemented in secondary schools for students with learning disabilities and mathematics difficulties. Included studies used a treatment-control group design. A total of 19 experimental and quasi-experimental studies…

Nearly all studies aiming to determine the effect of modern teaching methods on academic success using an experimental design contain control groups in which traditional methods are used. Effect of traditional methods in geometry and numbers learning domains on academic achievement has not been conclusively studied by researchers yet. On the other…

The statistical method "meta-analysis" is perhaps unique as a contribution to empirical inquiry of many types because it arose entirely within the practice of education research. In spite of its origins, meta-analysis has found its widest application and most important contributions in the field of medicine. Contrasting the success of…

This study uses data from a comprehensive database of U.S. early childhood education program evaluations published between 1960 and 2007 to evaluate the relationship between class size, child-teacher ratio, and program effect sizes for cognitive, achievement, and socioemotional outcomes. Both class size and child-teacher ratio showed nonlinear…

The "assessment 'for' learning" movement in education has increased attention to self-grading and peer-grading practices in primary and secondary schools. This research synthesis examined several questions pertaining to the use of self-grading and peer-grading in conjunction with criterion-referenced testing in 3rd- through…

This review describes a meta-analysis of findings from 50 controlled evaluations of intelligent computer tutoring systems. The median effect of intelligent tutoring in the 50 evaluations was to raise test scores 0.66 standard deviations over conventional levels, or from the 50th to the 75th percentile. However, the amount of improvement found in…

This study applied systematic meta-analytic procedures to summarize findings from experimental and quasi-experimental investigations into the effectiveness of using the tools and techniques of corpus linguistics for second language learning or use, here referred to as data-driven learning (DDL). Analysis of 64 separate studies representing 88…

Today, with the development of science and technology and its rapid progress, the importance attached to science education has increased. This increase in interest has led to the development of the methods, techniques, and approaches that enable the students to be active, question and construct knowledge. The 5E learning model is one of them, and…

This article provides a meta-analysis on the effect of academic probation, student-faculty mentoring and need-based grants on various student outcomes. Using 25 (quasi-) experimental studies, we find that academic probation has a significant negative effect on retention (d = -0.17), while it does not have an effect on graduation. Student-faculty…

Studies of interventions' impact on reading self-efficacy have been conducted since the 1980s. The purpose of this project was to conduct a systematic review of these studies because the primary studies often yielded divergent results. Included studies entailed an intervention, addressed reading specifically, and reported explicit pre- and…
