INTRODUCTION Science education today faces significant challenges in meeting the diverse learning needs of students . Each student possesses a unique thinking style, which influences how they process information . , solve problems . , and comprehend scientific concepts . , . However, traditional teaching methods often overlook this diversity by adopting a Auone-size-fits-allAy approach, potentially hindering students from realizing their full potential . StudentsAo thinking styles are categorized into Abstract Random (AR). Concrete Random (CR). Abstract Sequential (AS), and Concrete Sequential (CS) . These categories form a critical basis for implementing differentiated instruction that tailors teaching to individual student needs. Differentiated instruction requires Journal homepage: http://cahaya-ic. com/index. php/ISEJ A ISSN: 2716-3725 teachers to address individual needs by identifying students' abilities, interests, and learning styles and selecting appropriate teaching strategies . The practical implementation of this approach has yielded significant outcomes. A study conducted at Elementary school Adisucipto 1 Yogyakarta demonstrated the positive impact of differentiated instruction in Civics Education . Additionally, this approach aims to align learning with studentsAo interests and readiness levels, enhance motivation and academic performance, foster harmonious teacher-student relationships, and promote independence and respect for diversity . Nevertheless, implementing differentiated instruction is not without challenges. Key obstacles include time management difficulties, the complexity of material preparation, and challenges in conducting fair assessments . In this context, a thinking-style-based approach may offer a solution by aligning teaching strategies with studentsAo cognitive preferences, as outlined in GregorcAos Thinking Style Model . This model categorizes students' thinking styles into AR. CR. AS, and CS, which are crucial for creating inclusive learning environments . This study is grounded in the integration of differentiated instruction theories and thinking style theories . The principles of differentiated instruction, as developed by Carol Ann Tomlinson adjustments in content, process, product, and learning environment form the foundation . These principles are complemented by GregorcAos Thinking Style Theory, which underpins the design of the learning modules in this study. With this approach, the study hypothesizes that aligning teaching strategies with studentsAo thinking styles can enhance engagement, understanding, and performance in science education. Constructivist learning theory also underpins this approach, emphasizing active engagement and personalized learning pathways in knowledge construction . Science education, with its focus on inquiry-based learning and concept application . , is highly suited to such transformative strategies. Most previous studies have focused on primary education . , . , . and specific subjects such as Civics Education . In contrast, this study explores science education at MTs Al-Khairaat Bora, addressing the unique cognitive challenges of adolescents. The study utilizes GregorcAos Thinking Style Model to identify studentsAo cognitive preferences and develop differentiated science learning modules. These modules are designed for Biology. Chemistry, and Physics, with learning activities tailored to each thinking style. Thinking styles such as analytical hadimu . , creative . , practical . , and reflective play a critical role in science education . , . Research indicates that accommodating studentsAo thinking styles enhances their conceptual understanding . , learning motivation . , and academic performance . In thi The transformation of science education based on thinking styles not only supports studentsAo intellectual diversity but also aligns with 21st-century education goals . , which emphasize critical . , creative . , and collaborative thinking skills . This study contributes to the body of knowledge by addressing key gaps in science education through the integration of differentiated instruction theories and GregorcAos Thinking Style Model. Specifically, it explores the following research questions: . How does the distribution of thinking styles among students influence their learning outcomes in science education? . To what extent can differentiated instruction based on thinking styles enhance studentsAo engagement, conceptual understanding, and academic RESEARCH METHOD This study employed a quasi-experimental design to explore the transformation of differentiated learning based on thinking styles in science education. The research took place at MTs Al-Khairaat Bora and involved 70 students . male and 34 femal. The thinking styles of the students were identified using GregorcAos Thinking Style Model, which classifies thinking styles into four categories: Abstract Random (AR). Concrete Random (CR). Abstract Sequential (AS), and Concrete Sequential (CS). The research procedure was carried out in several steps. First, the studentsAo thinking styles were identified using the Gregorc Thinking Style Inventory . This was followed by the development of differentiated learning modules tailored to the identified thinking styles. The modules were designed for science subjects and included learning activities that were aligned with the students' thinking preferences. In the implementation phase, science lessons were delivered using these differentiated modules. Teachers facilitated learning activities that catered to each student's identified thinking style. Group activities, discussions, hands-on tasks, and simulations were employed to ensure that learning was both engaging and effective. The primary instrument employed in this study was the Gregorc Thinking Style Inventory, adapted from Gregorc . , to classify students into four cognitive style groups: Abstract Random (AR). Concrete Random (CR). Abstract Sequential (AS), and Concrete Sequential (CS). The inventory was modified to suit the cultural and educational context of the students. Data collection methods included pre-test and post-test assessments to evaluate students' conceptual understanding, observation checklists to monitor engagement and participation, and student feedback surveys to capture motivation and learning experiences. The reliability of both the instrument and the data collection methods was assessed using CronbachAos Alpha, which yielded a value of 0. In. Sci. Ed. Vol. No. January 2025: 47 - 53 In. Sci. Ed. ISSN: 2716-3725 indicating high reliability across all measures. For data analysis, paired t-tests were used to compare pre-test and post-test scores to determine the effectiveness of the intervention. Descriptive statistics summarized the levels of student engagement and feedback responses, while qualitative data from observation notes and surveys were analyzed thematically to identify patterns and challenges during implementation. This systematic approach ensured a comprehensive evaluation of differentiated learning transformation based on thinking styles, providing insights into how tailored instruction can optimize students' learning experiences in science education. RESULTS AND DISCUSSION The results of the study indicate that students can be categorized into four main groups: Abstract Random (AR). Concrete Random (CR). Abstract Sequential (AS), and Concrete Sequential (CS), as well as several combinations of these thinking styles. This data provides an overview of studentsAo thinking preferences, which can be used to tailor learning activities to optimize their academic outcomes.
