Self-Efficacy and Students’ Mathematics Learning Ability in Indonesia: A Meta Analysis Study

Improving self-efficacy in the learning process of Mathematics is very important as the key to success in learning Mathematics. Self-efficacy in learning mathematics is a belief in one's ability to solve mathematical problems. Many studies have been conducted on the relationship between self-efficacy and students’ mathematics learning ability in Indonesia. However, there are different representations or conclusions regarding the results of this study. Therefore, this study aims to examine the relationship of self-efficacy to students' mathematics learning ability in Indonesia using a meta-analysis approach. This study analyzed 40 research publications in national and international journals that were screened with certain eligibility criteria. The effect size in this study was determined by an acceptable 95% confidence level. To support the accuracy of the calculations used JASP software. The results of the study found that the effect size value generated by using the random-effect model estimation in the research analyzed was (M* = 0.65) with the lower limit of the confidence interval (LLM* = 0.51) and the upper limit of the confidence interval (ULM* = 0.80). This correlation measure is included in the strong category. These findings indicate that there is a positive and significant relationship between self-efficacy and students' mathematics learning ability in Indonesia. This means that the higher the self-efficacy, the higher the mathematical ability, and the lower the self-efficacy, the lower the mathematical ability. These findings will provide a solid theoretical foundation to improve students' mathematical achievement in the future
