Analisis Kemampuan Pemecahan Masalah dalam Pembelajaran Matematika Diskrit pada Materi Graf dengan Pendekatan Andragogi dan Problem Based Learning Mahasiswa
Abstract
Penelitian ini bertujuan untuk menganalisis peningkatan kemampuan pemecahan masalah matematika mahasiswa Program Studi S1 Ilmu Komputer Universitas Pat Petulai pada materi Graf melalui integrasi pendekatan Andragogi dan Problem Based Learning (PBL). Penelitian kuantitatif deskriptif dengan desain one-group pretest-posttest ini melibatkan 28 mahasiswa kelas A angkatan aktif. Instrumen yang digunakan berupa tes kemampuan pemecahan masalah berdasarkan indikator Polya dan angket kemandirian belajar. Pengujian kualitas instrumen dilakukan melalui validitas korelasi Product Moment dan uji reliabilitas Cronbach’s Alpha. Analisis data dilakukan melalui statistik deskriptif, uji-t berpasangan (paired sample t-test), kalkulasi N-Gain, serta pengelompokan tingkat kemampuan pemecahan masalah. Hasil analisis statistik menunjukkan adanya peningkatan signifikan pada nilai rata-rata dari pretes ( ) ke postes ( ) dengan ( ). Rata-rata skor N-Gain sebesar berada pada kategori sedang menuju tinggi. Peningkatan tertinggi terjadi pada indikator memahami masalah dan merencanakan penyelesaian. Pembelajaran berbasis masalah yang dikombinasikan dengan prinsip andragogi terbukti efektif mendorong kemandirian belajar dan kemampuan analisis aplikatif mahasiswa dalam teori Graf
