This study investigates the concrete relationship among the motivation to contextualize mathematics, self-determination, intrinsic motivation, self-efficacy. The study was conducted in J.H. Cerilles State College. It further shows that intrinsic motivation mediates between motivation to contextualize mathematics and self-efficacy. This study utilizes a descriptive-correlational research design and measured using PLS-SEM (Partial Least Squares – Structural Equation Modeling) to evaluate the proposed model of constructs. Moreover, the level of significance was measured with p-value of 0.05. It was revealed that self-determination significantly and positively affects Intrinsic Motivation and Self-efficacy. Additionally, motivation to contextualize mathematics and intrinsic motivation have a direct relationship and significant effect towards self-efficacy. Intrinsic motivation mediates the relationship between self-determination and self-efficacy and also between motivation to contextualize mathematics and self-efficacy.
