Abstract

Pembelajaran pada pasca pandemi menjadi tantangan tersendiri. Upaya untuk meningkatkan kemampuan mahasiswa pada materi Operasi Aljabar Himpunan adalah dengan penerapan Lembar Kerja Mahasiswa Berbasis R2D (Reading, Relating, Discussion). Tujuan penelitian ini adalah mendiskripsikan pembelajaran Lembar Kerja Mahasiswa Berbasis R2D (Reading, Relating, Discussion) Materi Operasi Aljabar Himpunan. Jenis penelitian adalah Penelitian Tindakan Kelas pada mahasiswa angkatan 2022 unipa Kampus Blitar. Instrumen penelitian ini adalah tugas, lembar penilaian sikap dan kerja kelompok, lembar observasi dan tes. Teknik análisis data yang digunakan adalah análisis data kualitatif yaitu reduksi data, penyajian data dan penarikan kesimpulan. Berdasarkan hasil penelitian diperoleh bahwa hasil observasi dalam kategori baik, ketuntasan klasikal sebesar 85% artinya baik sekali.

Abstract

Students can study everyday mathematics with a story problem. Through this problem, students gain critical thinking experience in solving problems. The ability of students to solve problems through John Dewey's approach is also seen to deepen students' mathematical concepts in three-variable linear equation systems. Problem solving with John Dewey's approach consists of five stages. This method of research uses a qualitative descriptive approach with three persons as the subject of the research, with good, sufficient, and less as the categories of ability. The results of the research showed the subject's ability to solve a story problem with the John Dewey approach. Four given questions showed that the subject with a category of good ability can solve two problems with clear mathematical concepts. Whereas the student with sufficient ability can only solve one problem with an obvious mathematical concept, However, the subject with less ability is only able to solve a problem until the stage of inventorying several solutions, which is the third stage of problem solving with the approach of John Dewey.
