The factors causing students' learning difficulties are highly varied, including in mathematics education. Learning difficulties refer to the various challenges or barriers individuals face in the learning process, which can impact their ability to acquire, process, and apply knowledge and skills. Due to their diverse nature, these difficulties affect various aspects of the learning process. This study aims to describe the learning difficulties students face, particularly in mathematics education. The sample for this study comprises 25 students, specifically all students in class VIII-B. The data collection methods include tests, interviews, and documentation as supplementary data. The analysis reveals that 48% of the students fall into the "moderate" category of mathematics learning difficulties, while 40% are categorized as experiencing "difficult" challenges in learning mathematics. Specifically, in the topic of exponentiation, these learning difficulties stem from challenges in mastering and understanding the concepts, particularly in solving mathematical problems, and difficulties in number operations or lacking operational skills, leading to incorrect problem-solving. Interview results further support that students continue to experience significant difficulties in learning mathematics, especially in the topic of exponentiation.

This research was motivated by a preliminary study conducted at UPTD SMP Negeri 7 Gunungsitoli, which revealed that mathematics learning still employed conventional teaching models and that students' mathematical creative thinking skills were still relatively low. The aim of this study was to determine the effect of the Self-Directed Learning model on students' mathematical creative thinking abilities. The research method used was quantitative with a quasi-experimental approach and a pretest-posttest control group design. The population of the study was all eighth-grade students, with two classes selected through simple random sampling: class VIII-B (23 students) as the experimental group and class VIII-A (24 students) as the control group. The research instrument was an essay test designed to assess students' mathematical creative thinking skills. The results of the one-tailed hypothesis test showed that the calculated t-value was 5.118, which was greater than the t-table value of 1.682. Therefore, the null hypothesis (H₀) was rejected, and the alternative hypothesis (Hₐ) was accepted. Thus, it can be concluded that the Self-Directed Learning model has a significant effect on students' mathematical creative thinking abilities.
