The need for comprehensive and systematic research syntheses has been increasing as the number of primary studies has proliferated in educational sciences in recent years. That is the main reason why diverse applications of meta-analysis, which is one of the most effective ways of research synthesis, has been encouraged in many disciplines including social and educational sciences. The main purpose of this article is to provide a conceptual framework for meta-analysis by questioning its criticisms and strengths over other methods of research synthesis. In addition, some methodological and statistical considerations like comparison of fixed-effect and random-effects models, different measures of effect size, unit of analysis, validity issues including publication bias and quality of primary studies, heterogeneity, moderator and power analyses in meta-analysis are discussed in detail. Moreover, brief information about software for statistical analyses performed in meta-analysis and a summary of standards for reporting meta-analysis are provided within the scope of this article. How well meta-analyses are conducted and reported is crucial since it has essential roles not only for cumulative nature of science but for policy makers and practitioners as well. Thus, we aim to provide the meta-analysts with an introductory-level guideline for their meta-analysis research.

A Meta-Synthesis Study Identifying the Landscapes of Pre- and In-service Math Teachers' Knowledge in the Turkish Context GULMEZ-DAG, Gulcin; Yıldırım, Ali (2016-01-01) This study aims to present a synthesis of empirical studies conducted in Turkey on pre- and in-service math teachers' knowledge and to recapitulate the existing conceptualization in this particular line of research in the local context. Considering the interwoven and sophisticated nature of teachers' knowledge (Seidel & Shavelson, 2007), it sets out to enhance the understanding on what constitutes and should constitute these math teachers' knowledge by discovering the frequently studied research strands in ...
A Content analysis of early childhood education graduate theses written in Turkey Demirtaş İlhan, Seden; Tantekin Erden, Feyza; Department of Early Childhood Education (2017) This study aims to investigate descriptive characteristics, research topics and methodological procedures of master’s theses and doctoral dissertations regarding early childhood education in Turkey. Within the scope of the current study, 931 M.S. theses, and 171 Ph.D. dissertations were analyzed according to university, institute, department, publication year, the degree held by the advisor, research topic, the sample group, the city where the study took place, research setting of the study, the type of res...
A Content analysis of graduate theses concerning early childhood education in Turkey Ilhan, Seden Demirtas; Erden, Feyza (2019-04-01) This study aims to investigate the descriptive characteristics, research topics and methodological procedures of master's theses and doctoral dissertations regarding early childhood education in Turkey. Within the scope of the current study, 931 Master's theses and 171 doctoral dissertations were analyzed according to university, institute, department, publication year, academic title of the advisor, research topic, sample group, location in which the study took place, research setting of the study, type of...
A Causal Model of Students Achievement in an Introductory Mechanics Course Eryılmaz, Ali (1999-01-01) The purpose of this study is to find out the factors affecting students' achievement in introductory mechanics by employing the Factorial Modeling (FaM) procedure by using Statistical Packages for Social Sciences (SPSS) program. The subjects were 30 preservice physics teachers at Middle East Technical University (METU). Data were collected from Mechanics Diagnostic test, Science Logic test, and the information in the students' files at the METU registration office. This study had seven variates; (i) student...
A new framework for evaluation of field based academic performances of higher education institutions Ömrüuzun, Fatih; Baykal, Nazife; Akkaya, Ayşen; Department of Information Systems (2011) Measurement and evaluation of academic performance is an highly debated research area and results of the studies in this area are closely followed by a large segment of the society. In general, researches conducted in this domain evaluate higher education institutions as a whole, but such an approach actually represents an average performance of the research fields, which are actively studied by the members of institutions. This may be misleading, because academic performance varies for each university depe...
