Abstract

This study was conducted with the aim of describing the forms of conceptual errors made by Mathematics Education study program students in solving set and function problems in real numbers, and analyzing the causes of errors made. The research method used was qualitative with descriptive method. The research subjects consisted of five students who were randomly selected, with the condition that they had taken related courses but still showed errors in working on problems. Data were collected through a questionnaire test designed to reveal students' conceptual understanding and analyzed using Kastolan's error classification. The results showed that procedural error was the most dominant type of error, with a percentage of 60%. Conceptual errors and technical errors each had a percentage of 20%. This finding shows that students still have difficulty in following the steps of solving problems coherently, understanding basic concepts, and performing calculation operations carefully. Therefore, improvement is needed in learning strategies that emphasize concept understanding, procedural accuracy, and technical accuracy

Abstract

Penelitian ini bertujuan untuk meningkatkan pemahaman siswa kelas X SMA terhadap materi logaritma dengan menggunakan media pembelajaran tangga logaritma. Dalam penelitian ini, 18 siswa diukur kemajuan pemahaman mereka melalui analisis nilai pre-test dan post-test. Metode analisis yang digunakan adalah uji korelasi Pearson dan Spearman. Hasil analisis menunjukkan bahwa nilai korelasi Pearson mencapai 0,88, sementara korelasi Spearman mencapai 0,95, keduanya mengindikasikan adanya hubungan positif yang sangat kuat antara nilai pre-test dan post-test. Temuan ini menunjukkan bahwa siswa dengan pemahaman awal yang baik cenderung mencapai hasil yang lebih tinggi setelah pembelajaran, sehingga membuktikan efektivitas media tangga logaritma dalam meningkatkan pemahaman siswa terhadap materi logaritma secara signifikan.
