Abstract
This study aimed to determine the relationship and predictive power of academic self-concept and motivation to tertiary students' Mathematics achievement. This descriptive correlational research was conducted with 347 college students in selected tertiary schools in Davao de Oro. Mean scores, Pearson's Correlation Coefficient, and linear regression analysis were utilized to analyze the data. The study's result revealed that the students' academic self-concept is moderate, and their learning motivation is high. The study also reported a very satisfactory level of performance in Mathematics. Further, academic self-concept and motivation significantly predict students' mathematics achievement in Mathematics. These findings suggest that academic self-concept and motivation are vital factors in enhancing students' achievement in Mathematics. This study recommended integrating academic self-concept and motivation to amplify students' achievement in Mathematics, promoting a comprehensive approach to learning success.
