Abstract

This study was motivated by the low mathematics learning outcomes of fifth-grade students at SD Negeri 106232 Penggalangan, which are believed to stem from weak critical thinking and problem-solving skills. The purpose of this research was to evaluate the effectiveness of the Problem Based Learning (PBL) model in enhancing these two competencies. A quantitative approach was employed using a quasi-experimental method, involving two groups: an experimental class taught using the PBL model and a control class receiving conventional instruction. A total of 42 students were selected as samples through total sampling from both classes. The research instruments consisted of validated tests measuring critical thinking and problem-solving abilities. Data were analyzed using a two-way ANOVA test. The findings revealed a significant difference between the two groups, with students in the experimental class demonstrating higher levels of critical thinking and problem-solving skills. Furthermore, an interaction was found between the learning model and students’ initial mathematical ability in influencing learning outcomes. The study concludes that the Problem Based Learning model is effective in improving elementary school students’ critical thinking and problem-solving skills and can serve as an innovative instructional strategy

Abstract

Penelitian ini bertujuan untuk mendapatkan informasi tentang pengaruh sikap terhadap matematika, motivasi berprestasi dan kegiatan tutorial terhadap prestasi belajar matematika. Penelitian ini dilaksanakan pada Kelompok Belajar Mahasiswa Perguruan Tinggi Kabupaten Tangerang. Dalam penelitian ini, sebanyak 200 sampel dipilih secara random sampling, dan data dikumpulkan melalui survey, dan dianalisis dengan menggunakan analisis jalur. Hasil temuan menunjukkan bahwa: 1) prestasi belajar matematika dipengaruhi secara langsung secara positif oleh sikap terhadap matematika, motivasi berprestasi dan tutorial. kegiatan, 2) kegiatan tutorial telah dipengaruhi langsung secara positif oleh sikap terhadap matematika dan motivasi berprestasi. Berdasarkan hasil temuan dapat disimpulkan bahwa menghasilkan peningkatan belajar matematika dilihat dari pengaruh sikap terhadap matematika, motivasi berprestasi dan kegiatan tutorial terhadap prestasi belajar matematika.

Abstract

This study is motivated by the low level of mathematical problem-solving ability among elementary school students and the suboptimal implementation of learning approaches that connect mathematical concepts with real-life situations. This study aims to examine the effect of the Indonesian Realistic Mathematics Education (PMRI) approach and learning motivation, as well as their interaction, on the mathematical problem-solving ability of fourth-grade students at SDN 100590 Air Kanan. The method used in this study is a quasi-experimental design with a treatment by level (2 × 2) design and a pretest–posttest nonequivalent control group design. This study employed a saturated sampling technique with a total sample of 40 students. Data collection techniques included essay tests to measure mathematical problem-solving ability and questionnaires to assess learning motivation, both of which had been tested for validity and reliability. Hypothesis testing was conducted through prerequisite tests, t-tests, two-way analysis of variance (ANOVA), and follow-up tests. The results showed that there is a significant effect of the PMRI approach on students' mathematical problem-solving ability. In addition, learning motivation also has a significant effect on this ability. Furthermore, there is an interaction between the PMRI learning approach and learning motivation on students' mathematical problem-solving ability. Further findings indicate that students with high motivation in PMRI learning achieved the highest performance, while students with low motivation still showed improvement compared to those taught using the expository approach.
