The Impact of Motivation on Student’s Academics Performance: a Case Study of Metharath University Students

Limited understanding of how motivation influences academic performance in private universities remains a critical gap in higher education research, particularly within diverse and localized contexts. This study investigates the impact of motivation on students’ academic performance at Metharath University within the framework of sustainable education. The objectives focus on examining the relationship between motivation and academic performance and determining the predictive effect of motivation on students’ grades. A quantitative cross-sectional survey design was employed, involving 286 undergraduate students selected through stratified random sampling across three faculties. Data were collected using the Academic Motivation Scale (AMS) and analyzed using Pearson correlation and linear regression. The results revealed a strong positive correlation (r = 0.733, p < 0.001) and a significant predictive effect of motivation on academic performance (B = 0.733, p < 0.001). These findings indicate that higher levels of motivation are associated with improved academic outcomes, highlighting motivation as a key determinant of student success. The study contributes empirical evidence from a private university context and provides practical implications for educators and policymakers in designing motivation-enhancing learning environments. Limitations related to the cross-sectional design suggest the need for longitudinal research to further validate the findings.
