Abstract

This study aimed to reveal the effect level of use of materials in educational processes on students’ mathematics achievement. This study employed meta-analysis to quantitatively synthesize evidence from 75 experimental and quasi-experimental studies, providing a systematic evaluation of the effectiveness of educational materials. The results indicate that use of materials for educational purposes is an effective method for increasing students’ mathematics achievement, with a statistically significant overall effect size of .48. The study yielded that as the publication year increased, the effect of material use on student achievement also increased, articles reported higher effect sizes than dissertations/theses, quasi-experimental studies yielded higher effect sizes than experimental studies, the level of effect sizes varied between different learning domains, material use had the biggest effect on student achievement in collectivist countries, and studies with interventions by researchers yielded higher effect sizes. This study offers a comprehensive meta-analytic synthesis of 75 studies on the use of educational materials in mathematics education, demonstrating that material use is an effective approach for enhancing students’ mathematics achievement.
