Abstract

This present study aims to examine the effect of GeoGebra-assisted interactive learning on student mathematical achievement of coordinate system. The study applied a quasi-experimental method that included 41 fifth grade students from a private Islamic school in Pekanbaru, Riau. The students were randomized into an experimental group (n=21) that received GeoGebra-assisted interactive learning and a control group (n=20) that received traditional teaching approach. Student mathematical achievement was measured using items of coordinate system developed by the researchers, and the data gathering in this study was analyzed using nonparametric statistical analysis. The findings indicated that there was significant statistical difference in student mathematical achievement of coordinate system between the experimental and control group (Asymp. Sig. (2-tailed) = 0.000 < 0.05)). The study concluded that the instruction based on GeoGebra-assisted interactive learning had a statistically significant positive effect on improving student mathematical achievement of coordinate system.

Abstract

Mathematical proofs play a paramount role in developing 21st-century skills, and the use of technology in mathematics learning has widely paved the way in the instruction of mathematical proofs. In mathematics education, GeoGebra has a significant role as a dynamic mathematics software in supporting students' learning process. This study aims to use GeoGebra in supporting prospective elementary teachers' mathematical proofs of the volume of 3-D shapes. This research used a case study method with 23 first-year prospective elementary teachers as participants from a public university in Riau, Indonesia.  The data were gathered by means of students' work recordings in the GeoGebra classroom and video recordings from their interactions in the course of small group and classroom discussions. The videos were transcribed using verbatim, and then the mathematical proofs were analyzed using praxeological analysis. The findings show that prospective elementary teachers still had challenges to connect the construction of the volume of 3-D shapes using GeoGebra to its informal mathematical proofs. However, GeoGebra provides an opportunity to learn informal mathematical proofs for prospective elementary teachers.

Abstract

Computational thinking (CT) merupakan topik baru yang muncul dalam penelitian pendidikan matematika. Isu gender telah mendapat perhatian ilmiah untuk diselidiki di antara banyak faktor yang mempengaruhi CT siswa. Oleh karena itu, penelitian ini berusaha untuk mengeksplorasi pengaruh gender pada keterampilan CT siswa kelas lima sekolah dasar. Penelitian ini menggunakan penelitian kuantitatif dengan metode komparatif. Subjek penelitian ini adalah 120 siswa kelas V di Pekanbaru, Riau, Indonesia. Analisis data menggunakan uji parametrik untuk membandingkan keterampilan CT siswa secara umum dan tes non parametrik untuk membandingkan keterampilan CT siswa dalam empat kompetensi yaitu dekomposisi, berpikir algoritmik, pengenalan pola, dan abstraksi. Hasil temuan menunjukkan bahwa siswa memiliki kemampuan berpikir komputasi yang rendah dan tidak ada perbedaan kemampuan berpikir komputasi yang signifikan antara siswa laki-laki dan perempuan pada umumnya. Namun, pengenalan pola siswa laki-laki secara signifikan lebih tinggi daripada siswa perempuan. Ini menyiratkan bahwa pembuat kebijakan perlu mempertimbangkan CT sebagai bagian dari kurikulum matematika di sekolah dasar. Computational thinking (CT) has become an emerging topic in mathematics education research. The gender issue has gained scholarly attention to be investigated among many factors affecting students' CT. Therefore, the present study seeks to explore the effect of gender on fifth-grade students' CT skills. This study applied quantitative research using the comparative method. The subjects were 120 fifth-grade students in Pekanbaru, Riau, Indonesia. Data analysis used the parametric test to compare students’ CT skills in general and the non-parametric test to compare students' CT skills in four competencies, decomposition, algorithmic thinking, pattern recognition, and abstraction. The findings indicate that students have low CT skills and no significant differences in CT skills between male and female students. However, male students' pattern recognition is significantly higher than female students. This implies that policymakers need to consider CT as part of the mathematics curriculum in primary schools.
