This study examines meta-analysis studies published in the field of educational sciences from 2010-2019, in journals indexed within the scope of the TÜBITAK ULAKBIM TR Directory. Of the 163 studies scanned, 26 meta-analysis studies that meet the inclusion criteria constitute the sample of this content analysis study. Within this research, a meta-analysis control form (MACF) developed by the researchers was used. The coding made by each of the two researchers has been considered, and it is concluded that the coherence between the codings was is sufficient (82%). The results of this research indicate that the most obvious problems in meta-analysis studies are: not establishing hypotheses; not calculating reliability between encoders; not using a flow chart (in terms of traceability); the use of commercial software in the analysis; not combining effect sizes on a common metric; use of the failsafe N in determining publication bias; evaluation of I[superscript 2] on the basis of categories; and decision making according to the result of the heterogeneity test in model determination. It is thought that the current study will contribute methodologically to the avoidance of errors in future meta-analysis studies.
