Abstract


Abstract 21st-century competence demands that students can reason according to current conditions that are relevant and accurate. Still, learning in the classroom uses a learning model that often does not support students’ reasoning. This study aims for differences in students mathematical reasoning abilities after being taught using an integrated problem-based learning model of numeracy literacy activities with students mathematical reasoning abilities using a problem-based learning model. This type of research is quasi-experimental design. The population is all grade IV elementary school students, Takalar. The sampling technique is cluster random sampling. The instrument uses a reasoning test. The results showed a difference in mathematical reasoning ability between students taught with an integrated problem-based learning model of numeracy literacy activities and students trained with problem-based learning. Teachers can improve students’ reasoning power by using a problem-based learning model integrated with numeracy literacy activities

 

Keywords Problem-based learning, numeracy literacy, reasoning, mathematics

 

Abstrak Kompetensi abad 21 menuntut siswa dapat bernalar sesuai dengan kondisi saat ini yang relevan dan akurat. Namun pembelajaran di kelas menggunakan model pembelajaran yang seringkali kurang mendukung penalaran siswa. Penelitian ini bertujuan untuk mengetahui perbedaan kemampuan penalaran matematis siswa setelah diajar menggunakan model pembelajaran terintegrasi aktivitas literasi berhitung dengan kemampuan penalaran matematis siswa menggunakan model pembelajaran berbasis masalah. Jenis penelitian ini adalah quasi-experimental design. Populasinya adalah seluruh siswa kelas IV SD Negeri, Takalar. Teknik pengambilan sampel adalah cluster random sampling. Instrumen yang digunakan adalah tes penalaran. Hasil penelitian menunjukkan adanya perbedaan kemampuan penalaran matematis antara siswa yang diajar dengan model pembelajaran berbasis masalah terpadu kegiatan literasi berhitung dan siswa yang dilatih dengan pembelajaran berbasis masalah. Guru dapat meningkatkan daya nalar siswa dengan menggunakan model pembelajaran berbasis masalah yang terintegrasi dengan kegiatan literasi berhitung.
