Abstract

Penelitian ini bertujuan mensintesis temuan penelitian mengenai pemahaman konseptual pecahan siswa sekolah dasar dengan fokus pada makna pecahan, subkonstruksi pecahan, model luas daerah, partitioning, unitizing, dan fraction magnitude. Pemahaman pecahan pada siswa sekolah dasar tidak cukup ditunjukkan oleh kemampuan melakukan operasi hitung, tetapi perlu mencakup kemampuan memaknai pecahan melalui berbagai subkonstruksi, representasi, dan hubungan kuantitatif. Penelitian menggunakan Narrative Literature Review dengan penelusuran dan pemilihan sumber secara purposif berdasarkan relevansi terhadap fokus kajian. Literatur dianalisis secara tematik dengan membandingkan konteks, metodologi, bentuk representasi, temuan konseptual, serta kesenjangan penelitian. Sintesis menunjukkan bahwa pecahan perlu dipahami sebagai konstruksi yang saling berhubungan, terutama part-whole, quotient, operator, ratio, dan measure. Model luas daerah efektif untuk membangun hubungan bagian-keseluruhan, tetapi tidak selalu menghasilkan pemahaman besaran pecahan dan transfer ke representasi lain. Temuan juga menunjukkan bahwa siswa dapat benar secara prosedural tetapi keliru dalam memaknai besaran, unit, atau representasi pecahan. Oleh karena itu, pembelajaran pecahan perlu menghubungkan area model dengan partitioning, unitizing, fraction-as-measure, dan fraction magnitude secara eksplisit.
