This study Investigate the dynamic interplay among my metrics interest, phobia, self efficiency and performance in students. Utilizing longitudinal data and the structural equation modelling techniques, we explore the reciprocal relationship between this key variables over time .our finding reveal complex dynamics mathematics interest positively predicts self efficacy and performance. While negatively influencing phobia. Moreover, bidirectional influences emerge Suggesting that changes in one domain can significantly impact other. Understanding the reciprocal relations shed lights on Effective strategies for enhancing mathematics learning experience and outcomes. Our study underscore the importance of addressing both effective and cognitive factors in mathematics education to foster positive academic trajectories and reduce phobia related barriers.
