Controlled motivation and physics achievement: a serial mediation analysis through self-efficacy and learning strategies in Chinese high school students.

Background: In high-stakes examination contexts such as China's Gaokao system, students frequently experience controlled motivation characterized by external pressure and learning anxiety. While research consistently demonstrates that controlled motivation undermines academic achievement, the psychological mechanisms through which this occurs remain underspecified. This study examined whether and how controlled motivation influences physics achievement through sequential effects on self-efficacy beliefs and learning strategy use among Chinese high school students. Methods: A total of 496 s-year high school students (65.9% male; Results: The negative association between controlled motivation and physics achievement operates primarily through psychological and behavioral mechanisms rather than through direct pathways. These findings suggest that interventions targeting self-efficacy enhancement and learning strategy support may effectively buffer against the detrimental effects of external pressure in high-stakes educational contexts. This research integrates self-determination theory, social cognitive theory, and self-regulated learning theory into a unified framework for understanding motivation-achievement relationships. Conclusion: These findings suggest that interventions targeting self-efficacy enhancement and learning strategy instruction could potentially buffer against the detrimental correlates of external pressure in high-stakes educational contexts. The research contributes to theoretical understanding by demonstrating empirical support for an integrated framework combining self-determination theory, social cognitive theory, and self-regulated learning theory in explaining motivation-achievement relationships.
