Abstract

This study aims to analyze students’ errors in solving exponent problems in terms of conceptual understanding, skills, and problem-solving aspects. The research method employed was descriptive qualitative with two students of SMA St. Arnoldus Janssen Kupang as subjects, selected based on test results and teacher recommendations. The research instruments consisted of written tests and interviews, while the data analysis techniques included data reduction, data presentation, and conclusion drawing. The results showed that the first subject made errors in the problem-solving indicator on question number 2 and errors in all indicators on question number 3. Meanwhile, the second subject made errors in conceptual understanding and skills on question number 1 and complete errors on question number 3. Overall, the most dominant errors committed by students were in conceptual understanding, skills, and problem-solving, particularly in applying the properties of exponents. These findings provide important implications for teachers to emphasize concept-based learning and provide varied practice problems to improve students’ skills and problem-solving abilities.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan profil pemahaman mahasiswa dalam menyelesaikan soal determinan matriks berdasarkan teori pemahaman instrumental dan relasional. Jenis penelitian ini adalah deskriptif kualitatif dengan subjek enam mahasiswa Program Studi Pendidikan Matematika Universitas Katolik Widya Mandira Kupang dari semester 3, 5, dan 7 yang dipilih menggunakan teknik purposive sampling. Instrumen penelitian meliputi tes tertulis soal uraian determinan matriks dan wawancara mendalam. Analisis data dilakukan melalui tahap reduksi, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa mayoritas subjek cenderung memiliki pemahaman instrumental. Hal ini ditunjukkan dengan kemampuan mahasiswa menerapkan metode Sarrus atau ekspansi kofaktor secara prosedural, namun gagal menjelaskan alasan logis penggunaan metode tersebut serta mengalami kesulitan signifikan saat menghadapi soal yang melibatkan variabel aljabar daripada angka numerik. Temuan ini mengindikasikan bahwa penguasaan konsep mahasiswa masih terbatas pada keterampilan algoritma rutin dan belum mencapai kedalaman pemahaman relasional yang memungkinkan penyelesaian masalah secara kreatif.
