Representasi Matematis Siswa SMA Ditinjau Dari Gaya Kognitif Field Dependent Dan Field Independent
Mathematical Representation Students Of Senior High School In Terms Of Field Dependent And Field Independent Cognitive Style
Representasi matematis penting untuk dikuasai siswa, karena membantu siswa untuk mengungkapkan ide-ide yang dimiliki siswa dalam berbagai bentuk representasi. Salah satu hal yang mempengaruhi perbedaan representasi siswa dalam menyelesaikan masalah adalah gaya kognitif siswa. Penelitian deskriptif kualitatif ini bertujuan untuk mendeskripsikan representasi matematis siswa SMA ditinjau dari gaya kognitif field dependent dan field independent. Subjek dalam penelitian yaitu dua siswa SMA kelas XI berjenis kelamin laki-laki dan berkemampuan matematika tinggi, yaitu satu siswa dengan gaya kognitif field dependent dan satu siswa dengan gaya kognitif field independent. Metode pengumpulan data diperoleh melalui GEFT (Group Embedded Figures Test), TKM (Tes Kemampuan Matematika), tes representasi matematis, dan wawancara. Hasil penelitian menunjukkan subjek dengan gaya kognitif field dependent merepresentasikan ide untuk mengerjakan soal dengan representasi simbol dan verbal. Subjek dengan gaya kognitif field independent merepresentasikan ide untuk mengerjakan soal dengan representasi simbol, visual dan verbal. Representasi simbol dan visual dilihat dari jawaban subjek, untuk representasi verbal berdasarkan penjelasan subjek pada saat wawancara.
Mathematical representation was important for students to master, because it helped students to express ideas that students had in various forms of representation. One of the things that affect the differences in student representation in problems solving is the student’s cognitive style. This qualitative descriptive study aims to describe the mathematical representation of senior high school students in terms of the field dependent and field independent cognitive styles. The subjects in the study were two senior high school students of class XI, who were male and had high mathematical abilities, namely one student with a field dependent cognitive style and one student with a field independent cognitive style. Data collection methods were obtained through the GEFT (Group Embedded Figures Test), TKM (Mathematics Ability Test), mathematical representation tests, and interviews. The results showed that subject with the field dependent cognitive style represented the idea of working on the problem with symbolic and verbal representations. Subject with the field independent cognitive style represented the idea of working on the problem with symbolic, visual, and verbal representations. Symbol and visual representations seen from the subject answer, for verbal representation based on the subject explanation during the interview.
