EXPLORING FACTORS RELATED TO MATHEMATICAL PROBLEM SOLVING IN STATISTICS AT SMP NEGERI 2 CENTRAL JAKARTA
Abstract
This study aims to explore students' learning experiences in understanding and solving mathematical problems in statistics and identify factors related to the problem-solving process. The study used an exploratory mixed-methods design that integrates descriptive questionnaire data with qualitative interview data. Participants consisted of 34 ninth-grade students from one class at SMP Negeri 2 Central Jakarta in the 2023/2024 academic year. Questionnaire data were analyzed using mean scores and percentages based on a five-level Likert scale, while interview data were coded thematically to explain quantitative patterns. The results showed three main categories related to students' problem-solving experiences: internal factors, external factors, and independent learning strategies. The highest average score was found in the family and peer environment (3.95), followed by the school and teacher environment (3.78), problem-solving barriers (3.71), cognitive ability and conceptual understanding (3.46), independent learning strategies (3.34), and learning motivation (3.22). Students' main difficulties were related to understanding long word problems and selecting appropriate measures of central tendency. Interviews confirmed that peer discussions and teacher explanations helped some students understand the material, but peer interactions could also disrupt concentration. The contribution of this study lies in the integrated mapping of the relationship between cognitive, affective, environmental, and learning strategy factors in students' experiences solving statistical problems.
Penelitian ini bertujuan mengeksplorasi pengalaman belajar siswa dalam memahami dan menyelesaikan masalah matematika pada materi statistika serta mengidentifikasi faktor-faktor yang berkaitan dengan proses pemecahan masalah. Penelitian menggunakan desain mixed methods eksploratif yang mengintegrasikan data kuesioner deskriptif dengan data wawancara kualitatif. Partisipan terdiri atas 34 siswa kelas IX dari satu kelas di SMP Negeri 2 Jakarta Pusat tahun ajaran 2023/2024. Data kuesioner dianalisis menggunakan skor rata-rata dan persentase berdasarkan skala Likert lima tingkat, sedangkan data wawancara dikodekan secara tematik untuk menjelaskan pola kuantitatif. Hasil penelitian menunjukkan tiga kategori utama yang berkaitan dengan pengalaman pemecahan masalah siswa, yaitu faktor internal, faktor eksternal, dan strategi pembelajaran mandiri. Skor rata-rata tertinggi terdapat pada lingkungan keluarga dan teman sebaya (3,95), diikuti lingkungan sekolah dan guru (3,78), hambatan pemecahan masalah (3,71), kemampuan kognitif dan pemahaman konseptual (3,46), strategi pembelajaran mandiri (3,34), dan motivasi belajar (3,22). Kesulitan utama siswa berkaitan dengan pemahaman soal cerita yang panjang dan pemilihan ukuran pemusatan data yang sesuai. Wawancara memperkuat bahwa diskusi teman sebaya dan penjelasan guru membantu sebagian siswa memahami materi, tetapi interaksi sebaya juga dapat mengganggu konsentrasi. Kontribusi penelitian ini terletak pada pemetaan terpadu mengenai keterkaitan faktor kognitif, afektif, lingkungan, dan strategi belajar dalam pengalaman siswa menyelesaikan masalah statistika.
