Abstract

This study is motivated by the gap between the importance of mathematical communication skills and the fact that such skills remain low in practice. The objectives of this research are: to determine the improvement of mathematical communication skills of school students who use the Problem-Based Learning (PBL) model assisted by GeoGebra compared to conventional learning. The research employed a mixed-method approach with a convergent parallel design. Subject of thi research is 64 eighth-grade students divided into experimental and control classes. Research instruments included a mathematical communication skills test and a response questionnaire. Quantitative data were analyzed through normality, homogeneity, and t-tests, while qualitative data were analyzed using data reduction, data display, and conclusion drawing techniques. The results show that students who learned through the PBL model assisted by GeoGebra achieved better mathematical communication skills than those in conventional learning. Students’ responses toward the learning process were generally positive, although some faced time limitations and difficulties operating GeoGebra. This study provides an effective technology-based learning model alternative.

Abstract

This study attempts to see the improvement of students' mathematical problem-solving abilities. The population in this study was conducted at SMP Negeri 5 Padalarang with a sample of two classes, namely the experimental class, namely VIII-D, consisting of 41 students and the control class, namely VIII-B, with a total of 40 students. This study uses pretest and posttest results processed using SPSS, then for the results of the improvement seen in the results of the N-Gain data. From the results of the analysis, it proves that students' mathematical problem-solving abilities have experienced significant development. The development of the experimental class by applying the Scratch-assisted Scientific approach is better than the control class whose learning applies the conventional approach. This shows that the ability of the Scratch-assisted Scientific approach is able to provide an increase in students' mathematical problem-solving abilities.

Abstract

This study employs a development research design using the ADDIE framework to create fraction teaching materials grounded in Realistic Mathematics Education (RME). It incorporates the Realistic Fraction application to enhance mathematical communication and self-confidence among MI students. The research subjects were third-grade pupils at MI in Bandung. The study utilized several assessment tools, including a content validation scale, a face validation, and a practicality scale. The study found the training materials met acceptable standards. During the restricted testing period, it was discovered that the fraction teaching materials require further adjustment, such as reducing the language. The training materials scores met the following criteria: content validity, face validity, and practicality. Expert and teacher assessments rated them as very valid, while students rated the practicality trial as very practical. These results make the instructional materials appropriate for use in experimental learning to improve third-grade students' mathematics communication abilities and self-confidence regarding fractions.

Abstract

The purpose of this study is to examine how PjBL supported by Canva enhances junior high school students’ mathematical reasoning skills. A mixed-method approach with an explanatory sequential design was employed. The subjects of this study were 8th-grade students of SMP Arroyan in Bogor Regency. They were divided into two classes: an experimental class and a control class, each consisting of 27 students. Five essay questions designed to assess mathematical reasoning ability were used as the research instrument. Data analysis involved normality testing, homogeneity testing, N-gain analysis, and t-tests, supported by student response surveys and observational data. The average score increased from 45.88 to 85.56 when comparing pretest and posttest results. This improvement falls into the high category, with an N-gain score of 0.72. According to the t-test results, the experimental and control classes showed significantly different improvements (p < 0.05). Additionally, 77.96% of students gave responses categorized as very good toward the learning process. Therefore, the use of PjBL supported by Canva can help enhance students’ mathematical reasoning abilities.

Abstract

Kemampuan Pemecahan Masalah Matematis (KPMM) adalah keterampilan esensial yang perlu dimiliki dan dikuasai siswa, terutama dalam menyelesaikan masalah sehari-hari namun realitas di lapangan menunjukkan kemampuan memecahkan masalah masih rendah. Dalam mendukung peningkatan KPMM, maka diperlukan bahan ajar yang membantu siswa untuk belajar secara aktif dan tidak menimbulkan perasaan bosan pada diri siswa ketika siswa mempelajari matematika di sekolah. Tujuan penelitian ini  mengembangkan bahan ajar menggunakan pendekatan berbasis masalah berbantuan geogebra. Design Research adalah metode yang dipergunakan pada  penelitian ini. Penelitian ini terbagi menjadi dua bagian, yaitu desain perencanaan dan desain evaluasi formatif. Subjek pada penelitian adalah  38 siswa SMK  Gema Karya Bahana di Kota Bekasi Kelas X.  Alat yang digunakan dalam pengumpulan data berupa  skala sikap, wawancara, dokumentasi dan uji coba soal. Pengolahan data menggunakan cara kuantitatif dan kualitatif. Kesimpulan pada penelitian ini adalah  bahan ajar menggunakan pendekatan berbasis masalah berbantuan geogebra sangat valid, praktis dan sangat efektif dalam meningkatkan KPMM terutama dalam materi Program Linear, sehingga bahan ajar menggunakan pendekatan berbasis masalah berbantuan geogebra dapat dipergunakan sebagai alternatif  dalam meningkatkan KPMM siswa
