Abstract

[English]: This study seeks to analyse the implementation of a constructivist approach through portfolio-based assessment in enhancing students’ understanding of mathematical concepts. The research was carried out at a private university in the East Lombok region using a qualitative methodology with a case study design. Data collection techniques included classroom observations, in-depth interviews, and analysis of students’ portfolio documents. The findings indicate that the integration of a constructivist framework with portfolio assessment contributes to a transformation in the learning paradigm, shifting from lecturer-centered instruction toward a more reflective and collaborative learning environment. Students exhibited notable improvement in their conceptual comprehension, ability to establish interconceptual relationships, engagement in self-reflection, and application of mathematical concepts, as evidenced by average portfolio scores exceeding 80. Qualitative analysis further indicates that students were able to articulate the mathematical reasoning underlying procedures, identifying and correcting conceptual misconceptions, and contextualizing abstract concepts within real-life situations. The study also highlights the pivotal role of social interaction during peer-review activities and lecturer facilitation as forms of scaffolding that support the development of students’ mathematical understanding.

[Bahasa]: Penelitian ini bertujuan menganalisis implementasi pendekatan konstruktivistik melalui penilaian portofolio dalam meningkatkan kemampuan pemahaman konsep matematis mahasiswa. Penelitian dilakukan pada salah satu perguruan tinggi swasta di Lombok Timur menggunakan pendekatan kualitatif dengan desain studi kasus. Data diperoleh melalui observasi, wawancara mendalam, dan analisis dokumen portofolio mahasiswa. Hasil penelitian mengindikasikan bahwa pendekatan konstruktivistik berbasis portofolio mampu mengubah paradigma pembelajaran dari berpusat pada dosen menuju pembelajaran reflektif dan kolaboratif. Mahasiswa menunjukkan peningkatan signifikan dalam pemahaman konseptual, koneksi antar konsep, refleksi diri, dan penerapan konsep, yang tercermin dalam nilai rata-rata portofolio di atas 80. Analisis kualitatif mengungkapkan bahwa mahasiswa mampu menjelaskan alasan matematis di balik prosedur, memperbaiki kesalahan konseptual, dan mengaitkan konsep dengan konteks kehidupan nyata. Penelitian ini menegaskan bahwa interaksi sosial dalam kegiatan peer-review dan bimbingan dosen berperan penting sebagai scaffolding dalam membangun pemahaman matematis mahasiswa.
