Abstract

Penelitian ini bertujuan untuk mendeskripsikan jenis konflik commognitive mahasiswa– konflik kognitif yang yang dianalisis dari komponen commognitive. Metode penelitian terdiri atas empat tahap yaitu persiapan, pengumpulan data, mentranskrip data, analisis data. Sebanyak 10 mahasiswa diberi lembar soal matematika, dikelompokkan menjadi dua kelompok, yaitu memiliki indikasi adanya konflik commognitive dan tidak. Dua mahasiswa yang dicurigai memiliki konflik commognitive dipilih sebagai subyek penelitian dan diwawancara mendalam untuk menggali informasi lebih lanjut tentang jenis konflik commognitive. Hasil penelitian menunjukkan bahwa konflik commognitive terjadi pada saat subyek menentukan nilai ekstrim fungsi berdasarkan grafik yang dibuat (visual mediators), alasan–alasan yang dikemukakan subyek dalam menentukan nilai ekstrim fungsi kuadrat (narratives), serta pengulangan langkah yang dilakukan (routines). Penggunaan istilah nilai ekstrim, nilai balik, titik potong pada sumbu koordinat (words use) tidak terdapat konflik commognitive.

Abstract

This research aims to describe students' cognitive abilities in mathematical modeling material. The methods used in this research are preparation, data collection, transcription and analysis. A total of nine students who were grouped into three groups were given mathematics problem sheets, containing contextual story problems consisting of one number regarding mathematical modeling. A student representing his group was selected as a research subject based on Polya indicators and was interviewed in a semi-structured and in-depth manner to dig up further information and then analyzed cognitively. The research results show that the research subjects can solve mathematical problems well. The subject can communicate ordinary sentences well into mathematical models. The components of words use, visual mediators, narratives, and routines show that students' cognitive ability in solving mathematical contextual problems is very good in mathematical modeling material.
