Özet:

This meta-analysis study aimed to examine the effect of data literacy education, which affects data-based decision processes, on data use knowledge and skills of school administrators and teachers. Therefore, theses of data literacy education for school administrators and teachers and relevant studies in peer-reviewed journals were examined through several databases. The study was conducted using the Comprehensive Meta-Analysis (CMA) software, using a total of eight studies published between 2006-2021. The results revealed that the selected studies were heterogeneous. Therefore, a random effects model was applied in the study. The overall effect size value of data literacy education was calculated as 2.16, suggesting that a data literacy education makes a positive high contribution to data use knowledge and skills of school administrators and teachers. The subgroup analyzes conducted to determine the source of heterogeneity in results have shown that data literacy education did not differ by type and country of publications, but varied by type of participants, where studies conducted with mixed participants had high effect values. Based on these results, it can be suggested that data literacy education given to school administrators and teachers should be expanded in all countries and education levels, and a meta-analysis of studies conducted in correlation between data literacy and different variables.
