Mindset and achievement in general chemistry: insights from Turkish undergraduate students

Abstract

Chemistry-specific mindsets have been shown to influence student engagement, self-efficacy, goal orientation, and academic achievement in chemistry. These beliefs are increasingly recognized as context-dependent, shaped through interactions within specific social and educational environments. The present study investigated the extent to which Turkish undergraduates have a growth chemistry mindset and how these beliefs relate to academic performance in chemistry across engineering and natural sciences majors. A total of 817 second-semester general chemistry students participated, completing surveys after the second midterm and prior to the final exam. The Chemistry Mindset Instrument (CheMI; Santos D. L., Barbera J. and Mooring S. R., (2022), Chem. Educ. Res. Pract., 23(3), 742–757) was used to assess students’ mindsets, while grade records provided measures of exam performance. Confirmatory factor analysis (CFA) supported the unidimensional structure of the CheMI, consistent with previous findings, providing evidence for its validity in this cultural and educational context. Structural equation modeling (SEM) examined whether chemistry mindset mediated the relationship between midterm and final exam performance across majors. Additional regression analyses explored how mindset influenced the midterm–final performance relationship among students with low, medium, and high levels of achievement. SEM results indicated that second midterm performance did not significantly predict mindset for either major. However, mindset significantly predicted final exam performance for engineering students, whereas this relationship was nonsignificant for natural sciences students. Furthermore, mindset emerged as a significant predictor only among the highest-performing students, suggesting that it may play a differentiating role at the upper end of achievement. These findings underscore the importance of considering mindset in instructional design and provide insights for targeted strategies to enhance student success in chemistry.
