Socioeconomic Inequality: The Mediating Role of Learning Motivation in Academic Achievement

This study re-examines the role of socioeconomic inequality in shaping academic achievement by introducing learning motivation as a key mediating mechanism. While socioeconomic status has long been recognized as a major determinant of educational outcomes, existing research often assumes a direct and deterministic relationship, overlooking the internal processes through which external conditions influence learning.

This study addresses this gap by proposing an integrative model that links socioeconomic inequality, learning motivation, and academic achievement in higher education.

Using a quantitative approach, this study employs a cross-sectional survey design involving undergraduate students. Data are collected through structured questionnaires and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to examine both direct and indirect relationships among variables. Socioeconomic inequality is operationalized through indicators such as access to resources, financial stability, and educational background, while learning motivation is conceptualized as a multidimensional construct encompassing intrinsic motivation, persistence, and engagement. The findings indicate that the direct effect of socioeconomic inequality on academic achievement is limited, while its indirect effect through learning motivation is substantial. Learning motivation emerges as a central mechanism that transforms structural conditions into academic outcomes, suggesting that students’ internal engagement plays a more decisive role than external resources alone. This study contributes to the literature by challenging deterministic views of educational inequality and advancing a mediated and process-oriented understanding of academic achievement. The findings highlight the need for educational policies that move beyond resource provision toward fostering student motivation as a key driver of learning.
