A Meta-Analysis: Emotional Intelligence and its Effect on Mathematics Achievement

Until now, many studies have been conducted on the correlation between emotional intelligence and mathematics achievement in Indonesia. However, there are different representations or conclusions regarding the results of the study. Therefore, this study aims to thoroughly investigate the effect of emotional intelligence and mathematics achievement on students in Indonesia and to detect the level of variation between studies using a meta-analysis approach. This study analyzed 36 primary studies with a sample of 2474 published in journals and campus repositories and filtered with certain eligibility criteria. To support the accuracy of the analysis results, JASP software is used. The results of the study found that the combined effect size value generated using the random-effect model estimation was (M = 0.65) with a standard error of (SEM = 0.07). This effect size belongs to the large effect category. Analysis of the study's level of variation was carried out by considering four moderator variables. The results of the analysis of moderator variables found that there were significant differences in the education level group (Qb = 62.94; p<0.05). Meanwhile, there was no difference in the publication type group (Qb = 0.64; p>0.05). and year of publication group (Qb = 4.16; p>0.05). These findings provide a strong theoretical foundation to improve students' mathematical achievement in the future.
