This study explores the alignment between science learning practices and children’s cognitive development stages based on Jean Piaget’s theory. Ten academic publications were systematically reviewed to examine how Piaget’s framework can be applied in science education. The findings highlight that integrating cognitive development theory is highly relevant for improving the quality of teaching and learning in schools. At the concrete operational stage (approximately 7–11 years), children learn best through direct experiences, manipulation of real objects, contextual media, and experiments that connect concepts with daily life. These methods help foster curiosity and reinforce conceptual understanding. As learners progress to the formal operational stage (around 11 years and above), they begin to think abstractly, reason logically, and analyze critically. At this level, student-centered approaches, inquiry-based methods, and constructivist learning become more effective in enhancing problem-solving, creativity, and higher-order thinking skills. The review also indicates that adapting instruction to developmental stages supports more meaningful and sustainable learning outcomes. In the Indonesian educational context, this approach can address challenges such as limited classroom facilities, diverse student learning styles, and a curriculum that is often overloaded. By applying Piaget’s insights, teachers can design learning strategies that bridge abstract concepts with concrete understanding, thus increasing student motivation and engagement. In conclusion, aligning science education with Piaget’s cognitive stages is an effective way to improve student performance and ensure long-term academic growth. The study provides valuable input for teachers, researchers, and policymakers in developing innovative, student-centered science and mathematics education.

Adapting to students’ learning styles is a key factor in enhancing the effectiveness of higher education, particularly in Informatics programs where learning preferences vary widely. This study aims to segment students based on their learning styles using the K-Means clustering algorithm, guided by the VARK model (Visual, Auditory, Read/Write, Kinesthetic). Data were collected from 130 Informatics students, including information on their learning preferences, and processed through normalization techniques. The optimal number of clusters was determined using the Elbow Method and Silhouette Score, and subsequent cluster interpretation was conducted. The results identified three dominant clusters, each representing distinct learning behavior patterns. These clusters were analyzed to recommend tailored instructional strategies for each group. Specifically, Visual learners were found to benefit from graphic-heavy materials, Auditory learners preferred lectures and discussions, Read/Write learners thrived on written content and detailed notes, while Kinesthetic learners responded best to hands-on activities. The findings support the development of adaptive, data-driven teaching approaches that align with the actual learning tendencies of students in Informatics. Moreover, the study demonstrates that the K-Means method is effective in systematically identifying student learning profiles, which can be used to inform instructional improvements. This personalized approach to teaching could significantly enhance learning outcomes by providing students with the most effective educational experiences tailored to their individual learning styles
