Abstract

Penelitian ini bersifat kualitatif dan deskriptif yang bertujuan untuk mengidentifikasi kemampuan penalaran matematis peserta didik MAN 1 Pontianak dalam menyelesaikan soal TIMSS konten geometri. Terdapat sembilan peserta didik yang terpilih selanjutnya dibentuk kedalam tiga kelompok yaitu kelompok yang memiliki kemampuan awal matematika tinggi, sedang, dan rendah. Instrumen yang digunakan dalam penelitian ini berupa 3 tes berbentuk uraian dan lembar wawancara untuk menggali kemampuan penalaran peserta didik secara mendalam. Berdasarkan hasil identifikasi ditemukan tujuh dari sembilan peserta didik memiliki kemampuan mengajukan dugaan yang akurat, sementara dua lainnya kurang akurat. Dari sembilan anak, hanya dua yang mampu memanipulasi fakta matematika dengan akurat, sementara lima lainnya masih kurang. Dua dari sembilan peserta didik mendapat hasil yang akurat pada indikator membentuk kesimpulan logis, sedangkan lima peserta didik kurang akurat dan dua peserta didik tidak akurat sama sekali. This research is qualitative and descriptive which aims to identify the mathematical reasoning ability of MAN 1 Pontianak students in solving TIMSS questions on geometry content. Nine students were selected and then formed into three groups, namely groups with high, medium, and low initial mathematical abilities. The instruments used in this study were 3 tests in the form of descriptions and interview sheets to explore students' reasoning skills in depth. Based on the identification results, it was found that seven out of nine learners could make accurate conjectures, while the other two were less accurate. Of the nine children, only two were able to manipulate mathematical facts accurately, while the other five were still lacking. Two out of nine learners got accurate results on the indicator of forming logical conclusions, while five learners were less accurate and two learners were not accurate at all.

Abstract

Purpose: This research aims to 1) analyze gender-based differences in visual mathematical thinking for solving algebraic problems, 2) explore how e-learning technology, specifically the Edlink platform, supports algebra understanding through visualization, and 3) assess the effectiveness of mathematical software in aiding students to visualize and solve algebraic problems. Method: A qualitative approach with a descriptive-exploratory method was used for this study. It involved a case study of students enrolled in the Mathematics Education Program who attended algebra courses. Data were collected through tests, questionnaires, interviews, direct observation, and documentation. The study sample consisted of 278 students, including 98 male and 180 female participants. Descriptive statistics and independent samples t-tests were employed to analyze the gender-based differences in visual thinking abilities. Findings: The results indicate that male students demonstrated more dominant visual mathematical thinking abilities compared to female students, particularly in understanding, imagining, and presenting algebraic solutions. Statistically, the independent samples t-test revealed a significant gender difference (p < 0.001). The use of the Edlink e-learning platform was found to be effective in aiding students' algebra understanding through enhanced visualization of mathematical concepts. Significance: The study concludes that gender differences affect visual mathematical thinking abilities, with male students showing greater proficiency in solving algebraic problems visually than female students. Furthermore, the integration of the Edlink e-learning platform significantly enhanced students' understanding of algebraic concepts through effective visualization. Therefore, incorporating technology in mathematics education can enrich the learning experience and improve student outcomes.
