Effect of Summer Vacation on Learning Loss in Mathematics: A Meta-Analysis of the Findings

The purpose of the present study was to perform a meta-analysis to draw conclusions about the effect of summer vacation on learning loss of students in mathematics, and also to identify potential moderators of its effects based on the examination of research literature over the past twenty-five years. The research performed meta-analysis model to examine the effect of summer vacation on learning loss in mathematics. Based on the inclusion criteria, eight independent studies were taken into consideration in the research. To explore possible differential effects on the outcome measure, six moderators were extracted from the included studies. The research indicated that summer vacation influences students negatively, resulting in learning loss in mathematics. Also, the research found no significant effect within sub-group variation in terms of year of publication, publication type, setting, and sample size, but not the instructional level and country.
