Abstract

Penelitian ini bertujuan untuk menganalisis karakteristik hambatan belajar siswa kelas 6 SD pada materi volume dan luas permukaan dari kubus dan balok. Hambatan belajar yang difokuskan pada peneliti yaitu hambatan ontogenik, hambatan epistemologi, dan hambatan didaktik. Metode penelitian yang digunakan adalah penelitian kualitatif deskriptif dengan menggunakan sampel sebanyak 3 siswa dari jenis kemampuan yang berbeda, yaitu kemampuan tinggi, sedang dan rendah. Sampel berasal dari salah satu sekolah dasar di kota Medan. Instrumen penelitian berupa tes soal berkaitan dengan volume dan luas permuakaan dari kubus dan balok serta wawancara. Hasil penelitian ini menunjukkan bahwa terdapatnya hambatan belajar siswa dari hambatan ontogenik, epistemologi, dan didaktik. Hambatan epistemologi terjadi pada siswa kemampuan sedang dan rendah, sedangkan hambatan ontogenik terjadi pada siswa yang memiliki kemampuan rendah, dan hambatan didaktik dialami oleh seluruh siswa (kemampuan tinggi, sedang, dan rendah). Perlunya rancangan  desain bahan ajar yang disusun sesuai dengan hambatan belajar yang dialami siswa, sehingga dapat meminimalisir kesulitan siswa dan menjadikan pembelajaran menarik dan bermakna.

Abstract

Improving students' mathematical competence such as problem-solving skills, mathematical communication, reasoning, and others can use the Problem Based Learning model. This study aims to analyze the impact of the Problem Based Learning model in improving the mathematical competence of students from primary school, junior high, and senior high school levels. The research method used is Systematic Literature Review (SLR). The sample comprises 17 research results on the PBL model in improving students' mathematical competence (concept understanding, problem-solving, and communication skills). The sample comes from indexed journals from the period 2012-2019. The key research question is how PBL influences students' mathematical competence based on the year of school, level of study, research location, and sample size. The SLR method can find an increase in the number of eight-year studies. The results showed that communication skills and understanding of mathematical concepts dominated research results in improving mathematical abilities through problem-based learning models. Most of the research was conducted at the junior high school level outside Java, with a sample size of 30 people or more. Based on the results of the review, the study’s conclusion proves the influence of the Problem Based Learning (PBL) model on students' mathematical competence.
