Abstract

Abstract Math education requires creative mathematical reasoning, especially in geometry, which requires visualization and spatial knowledge. Cognitive styles can influence these skills. This study examines the creative mathematical reasoning of eighth-grade students in addressing geometric problems, focusing on the influence of field-independent and field-dependent cognitive styles. This is a qualitative descriptive study. Cognitive styles were assessed using the GEFT, and two students exemplifying each cognitive style, with equal mathematics proficiency and gender, were purposively selected. Data were gathered through geometric problem-solving tasks and semi-structured interviews, focusing on three indicators of creative mathematical reasoning: creativity, plausibility, and anchoring. Time triangulation was used to ensure data validity. The findings indicate that both students developed new problem-solving strategies. The field-dependent student tended to argue based on personal preference and illogical links between the representation and the strategy. In contrast, the field-independent student generally argued from the problem's conditions. The field-dependent student applied the concept of area procedurally but lacked a deep understanding of its relationship to the given representation. In contrast, the field-independent student applied it consistently to both the representation and the calculations. This study shows that cognitive styles affect student problem-solving. Therefore, teachers are encouraged to create interactive or technology-based visual learning resources that help field-dependent students transform their visual comprehension into more substantial formal mathematical reasoning. Future research is recommended to apply larger-scale comparative studies to verify these cognitive patterns and explore the scalability of these reasoning models across more diverse demographic and educational backgrounds. Keywords: creative mathematical reasoning; geometric problems; field-dependent; field-independent Abstrak Penalaran matematis kreatif adalah aspek penting dalam pembelajaran matematika, terutama geometri, yang menuntut kemampuan visualisasi dan pemahaman spasial. Keterampilan-keterampilan ini dapat dipengaruhi oleh gaya kognitif. Penelitian ini bertujuan untuk mendeskripsikan penalaran matematis kreatif siswa dengan gaya kognitif field-independent dan field-dependent dalam menyelesaikan masalah geometris. Penelitian ini merupakan penelitian deskriptif kualitatif. Subjek penelitian adalah dua siswa SMP kelas VIII dari masing-masing gaya kognitif yang dipilih berdasarkan hasil tes GEFT, dengan kemampuan matematika yang setara dan memiliki gender yang sama. Data dikumpulkan melalui tugas pemecahan masalah geometri dan wawancara semi-terstruktur, dengan fokus pada tiga indikator: kreativitas, plausibilitas, dan anchoring. Triangulasi waktu digunakan untuk menjamin validitas data. Temuan menunjukkan bahwa kedua siswa menciptakan strategi pemecahan masalah baru. Akan tetapi, siswa field-dependent memberikan argumen berdasarkan keinginan dan tidak masuk akal antara representasi dan pemilihan strategi, sedangkan siswa field-independent memberikan argumen berdasarkan syarat soal. Siswa field-dependent menerapkan konsep luas bangun datar secara prosedural, namun tanpa pemahaman mendalam tentang hubungannya dengan representasi yang diberikan, sementara siswa field-independent menerapkannya secara konsisten dalam representasi dan perhitungan. Temuan ini menekankan pentingnya bagi guru untuk memprioritaskan pemahaman konseptual dalam pembelajaran matematika. Guru disarankan untuk mengembangkan sumber belajar interaktif atau berbasis teknologi yang dapat membantu siswa field-dependent meningkatkan pemahaman visual. Penelitian lebih lanjut disarankan untuk melakukan studi komparatif berskala lebih besar guna mengeksplorasi skalabilitas penalaran matematis kreatif di kalangan kelompok demografis dan latar belakang pendidikan yang lebih beragam. Kata Kunci: field-dependet; field-independent; masalah geometris; penalaran matematis kreatif
