The columns code meta-information about the publication ( author, year), about the reported statistics extracted from the publications ( tpos, tneg, cpos, cneg), and study characteristics ( ablat, alloc). In the running example below, we’ll use the BCG vaccine data set that compiles available evidence for the effectiveness of the BCG vaccine in preventing tuberculosis. Here we’ll give a quick run through of all the functionality currently supported in JASP. The engine behind this analysis power is the software developed in the metafor-project. These include fixed and random effects analysis, fixed and mixed effects meta-regression, forest and funnel plots, tests for funnel plot asymmetry, trim-and-fill and fail-safe N analysis, and more. The new release of JASP supports an extensive arrange of commonly used techniques for meta-analysis. The results of the studies combined with meta-analysis suggest that use of student-centered methods in Turkish language instruction is effective on the academic success of students.The JASP meta-analysis module was supported by a SSMART grant from the Berkeley Initiative for Transparency in the Social Sciences (BITSS), an initiative of the Center for Effective Global Action (CEGA). As a result of the study, it was determined that student-centered learning methods have an overall positive and high level effect on the academic success of students. This study was deemed necessary due to the unavailability of a study addressed at the methods employed in Turkish language instruction in the literature. Comprehensive Meta-Analysis CMA software was used for the calculations. Calculations of the addressed studies were made in accordance with random effects model due to the heterogeneity of effect size calculated in accordance with the fixed effects model. Effect size calculations of the determined methods were made individually. 22 studies, which qualified for the meta-analysis, were selected and analyses were conducted as necessary. The review revealed that there are 96 studies available on student-centered methods based on multiple intelligences, creative drama, collaboration and games. To this end, a literature review was conducted on the relevant studies conducted between 20 in order to determine the studies were suitable for the meta-analysis.
The aim of the present study is to determine the influence of student-centered methods employed in Turkish language instruction on the academic success of students through meta-analysis.
