Abstract
Kemampuan koneksi matematis merupakan kemampuan penting dalam pembelajaran matematika karena membantu siswa mengaitkan konsep antar topik, lintas disiplin, dan kehidupan nyata. Namun, kenyataannya kemampuan ini masih rendah karena pembelajaran cenderung satu arah dan minim media interaktif. Untuk mengatasinya, diterapkan model Problem Based Learning (PBL) dan didukung media visual interaktif seperti Scratch. Penelitian ini bertujuan mengetahui pengaruh model Problem Based Learning (PBL) berbantuan media Scratch terhadap kemampuan koneksi matematis siswa sekolah dasar. Metode yang digunakan adalah kuasi eksperimen dengan desain non-equivalent control group. Subjek penelitian terdiri dari 52 siswa kelas V SDN 2 Sindangkasih yang dibagi menjadi dua kelompok: eksperimen (model Problem Based Learning (PBL) berbantuan media Scratch) dan kontrol (pembelajaran konvensional dengan pendekatan saintifik). Instrumen penelitian berupa tes uraian koneksi matematis sebelum dan sesudah perlakuan. Hasil penelitian menunjukkan perbedaan signifikan. Model Problem Based Learning (PBL) berbantuan media Scratch berkontribusi sebesar 42,1% terhadap peningkatan kemampuan koneksi matematis siswa. Sehingga model Problem Based Learning (PBL) berbantuan media Scratch efektif meningkatkan kemampuan koneksi matematis siswa di sekolah dasar. ----- Mathematical connection ability is a crucial component of mathematics learning, as it enables students to relate concepts across topics, disciplines, and real-life situations. However, this ability remains low due to predominantly one-way instruction and the lack of interactive media. To address this issue, the Problem-Based Learning (PBL) model was implemented with the support of an interactive visual medium, Scratch. This study aimed to examine the effect of the PBL model assisted by Scratch on elementary students’ mathematical connection ability. A quasi-experimental method with a non-equivalent control group design was used. The subjects were 52 fifth-grade students from SDN 2 Sindangkasih, divided into an experimental group (PBL with Scratch) and a control group (conventional learning using a scientific approach). The research instrument consisted of mathematical connection essay tests administered before and after the treatment. The results indicated a significant difference between the two groups. The PBL model assisted by Scratch contributed 42.1% to the improvement of students’ mathematical connection ability. Therefore, the PBL model supported by Scratch is effective in enhancing elementary students mathematical connection skills.
