This study aims to examine the extent to which students' abilities are in understanding mathematical concepts in depth, connecting them, and applying them in various life contexts. Improving mathematical understanding is considered to have a significant influence on the world of education. This is reflected in three main aspects: improving learning outcomes, strengthening critical thinking skills, and readiness to face global challenges in the 21st century. Students' learning styles are one of the important factors that influence mathematical understanding. Learning styles can be divided into three, namely visual (relying on sight), auditory (through hearing), and kinesthetic (through physical activity). Each individual generally has all three styles, but one of them will be more dominant. Students' ability to recognize and adjust their learning styles with appropriate learning strategies contributes to their success in understanding the material. This study uses a quantitative approach with a correlational survey technique. The research sample consisted of 30 grade XI students of SMK Ristek Jaya Jakarta. Data analysis was carried out through several stages, including the validity and reliability of learning style instruments and descriptive and inferential statistical tests such as regression and normality. The results of the analysis showed that the scientific approach had a significant influence on students' mathematical understanding, with a determination coefficient of 70.39%. This means that this approach contributes greatly to improving mathematical understanding based on students' learning styles. This study suggests further studies to deepen understanding of this phenomenon and make it a reference in learning practices.

Science Education (IPA) has a very important role in the development of science, technology, and in forming critical and analytical thinking patterns of students. Through science learning, students not only gain knowledge about scientific concepts, but are also trained to think critically, systematically, and creatively in dealing with various problems. One aspect that influences the success of science learning is cognitive psychology, which focuses on how individuals process, store, and remember information. Cognitive psychology plays an important role in designing effective learning strategies, which are tailored to the way students understand and manage information. In addition, the learning paradigm used in science education also greatly influences the success of learning. The two main paradigms that are widely considered in science learning are absolutism and constructivism. The absolutism paradigm argues that knowledge is absolute and must be accepted without change, while the constructivism paradigm assumes that knowledge is built through experience and active interaction with the environment. This article aims to explore how the tradition of cognitive psychology influences science learning and examines the differences in the impact of the two paradigms in the context of science education in Indonesia. This discussion is expected to provide a deeper understanding of the importance of applying cognitive psychology and selecting the right learning paradigm in improving the quality of science education.
