Figure 1.

A path diagram shows the relationships between controlled motivation, self-efficacy, learning strategies, and physics achievement. Controlled motivation influences self-efficacy (a1 = -0.400), learning strategies (a2 = -0.178), and physics achievement directly (c' = -0.051, not significant). Self-efficacy affects physics achievement (b1 = 0.225), while learning strategies influence both self-efficacy (d21 = 0.533) and physics achievement (b2 = 0.311). The total effect of controlled motivation on physics achievement is noted as -0.279.

Serial mediation model with standardized path coefficients. Standardized regression coefficients are shown for each path. The dashed line represents the non-significant direct effect after controlling for mediators. p < 0.001.
