Malang: FMIPA Universitas Negeri Malang.Bodner, George M. Identifikasi Kesulitan Siswa Kelas XI MIA SMA Negeri 1 Kauman Tulungagung dalam Menyelesaikan Soal-soal Stoikiometri Menggunakan Analisis Langkah Penyelesaian Soal. The correlation of mastery of problem-solving steps for students in the upper group was 0.786 (high), the middle group was 0.883 (very high), and the lower group had a correlation score of 0.803 (very high).REFERENCESAmalia, F.R. There is a significant correlation between students' mastery of problem-solving steps. In contrast, the lower group was classified as low with mastery of Polya steps, respectively 85%, 68%, and 36%. The results showed that the students' problem-solving ability in the upper group was very high, the middle group was quite high. This study uses subjective test questions to determine the steps or methods students use to solve problem-solving test questions. Because solving stoichiometric' problems requires not only algorithmic skills but also a good understanding of chemical concepts. Based on several studies, it is known that there are students' difficulties in applying problem-solving as a problem-solving method, especially in stoichiometric material.
