Vocational school students have distinctive characteristics that are influenced by a variety of factors, including their social, cultural, and cognitive backgrounds. In the world of education, the development of creative thinking skills is an important aspect for vocational school students. However, each student's level of creativity varies, and one factor that contributes to this difference is cognitive style. This study aims to examine the influence of cognitive style on the mathematical creative thinking ability of high school students in Sumedang Regency. The method used is a qualitative approach with a descriptive design, where data is collected through mathematical creative thinking tests as well as semi-structured interviews. The study participants totaled 28 students, who were categorized based on their cognitive styles into Field-Independent (FI) and Field-Dependent (FD) groups. Data analysis was conducted through the process of reduction, presentation, and concluding, which revealed that students' cognitive style influenced their understanding and response to mathematical information. The results of the study revealed that students with FI's cognitive style tended to have higher creative thinking skills, able to solve problems with a more flexible and complex approach. In contrast, students with FD cognitive style have difficulty thinking flexibly and adapting to various methods, so their level of creativity in solving math problems is lower. This finding is expected to provide insight for educators in designing more effective learning strategies to encourage the development of student creativity in mathematics.

This study aims to analyze the numeracy literacy skills of seventh-grade students at SMP Negeri 2 Rancakalong. Numeracy literacy is a fundamental skill necessary for understanding and applying mathematical concepts in daily life. This research uses a qualitative method with a descriptive approach. The research sample consists of 30 students selected through purposive sampling. Data were collected through a numeracy literacy test, which includes three main indicators: number understanding, data interpretation, and solving numerical problems. The results show that the majority of students fall into the "sufficient" (33.33%) and "low" (30%) categories, with an overall average score of 45. Although there are a few students in the "good" and "very good" categories, their numbers are relatively small (6.67%). Factors contributing to the low numeracy literacy skills include a lack of connection between the test questions and real-life contexts, low learning motivation, and teaching methods that remain too theoretical. This study recommends the implementation of context-based learning, the use of technology in education, and training for teachers to enhance students' numeracy literacy. The findings of this study are expected to contribute to the development of more effective teaching strategies to improve numeracy literacy at the primary education level.
