Abstract


 

Penalaran kovariasional merupakan salah satu bentuk penalarana matematis yang perlu dimiliki seseorang baik untuk memahami konsep maupun menyelesaikan masalah yang berkenaan dengan kehidupan sehari-hari. Realitanya bahwa penalaran kovariasional mahasiswa tergolong rendah. Tujuan dari penelitian ini adalah untuk mengetahui penalaran kovariasional mahasiswa dalam memodelkan hubungan antara waktu dan kecepatan. Penelitian ini menggunakan pendekatan kualitatif dengan subjek sebanyak 87 mahasiswa semester 3. Analisis data yang dilakukan yaitu pengumpulan data, kondensasi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa penalaran kovariasional mahasiswa terbagi menjadi 5 kategori, yaitu mahasiswa memodelkan grafik namun tidak bermakna, Mahasiswa memodelkan grafik dengan menggeneralisasi masalah, mahasiswa memodelkan grafik yang terus naik sehingga tidak sesuai konteks, mahasiswa memodelkan grafik yang perubahan bentuknya tidak sesuai konteks, dan mahasiswa memodelkan grafik dengan rinci dan sesuai konteks.

 

Kata kunci: penalaran kovariasional, memodelkan grafik, waktu dan kecepatan
