In addition to cognitive factors, affective aspects, such as interest in learning, play an important role in determining student learning outcomes. Therefore, this study aims to analyze the effect of interest in learning on students' ability to solve exponential problems. This study uses a descriptive approach with a correlational method. The instruments used in this study are a learning interest questionnaire and an exponent ability test that have undergone validity and reliability tests. The data were analyzed using simple linear regression tests with the help of SPSS version 26. The results showed that learning interest had a positive and significant effect on students' ability to solve exponent problems. These findings emphasize the importance of teachers' efforts to stimulate and foster students' interest in learning through interactive, contextual, and student-centered learning.</p>2025-12-25T19:34:33+07:00Copyright (c) 2025 Journal of Research on Mathematics Instruction (JRMI)
