The present study aims to predict the role of learning approaches, studying strategies, metacognitive strategies, and reflective thinking on students’ academic achievements. A cross-sectional analytical study was carried out in Iran. The statistical population encompasses the all 5000 students at Roudehen Islamic Azad University throughout 2020-2021. According to Morgan's Table, the sample size was estimated to be 384 persons. Five standard questionnaires including studying strategies, learning approaches, metacognitive strategies, reflective thinking and academic achievement were used for data gathering. Structural equations based on partial least squares were used to analyze the data. The results showed a moderate relationship between learning approaches and metacognitive strategies while a significant relationship was observed between learning approaches, studying strategies, and reflective thinking (P<0.05). There was also a weak relationship between learning approaches and academic achievement. Beside, a moderate relationship was observed between metacognitive strategies and academic achievement, and a significant relationship was revealed between reflective thinking and academic achievement. Numerous factors affect academic achievement. Managers and families by recognizing these variables and providing appropriate conditions could smooth the rate of success for students.
