Abstract

This study aimed to describe students' mathematical representation ability in solving contextual problems on circle material. The approach used is a qualitative approach with a descriptive research type. The research subjects came from class VIII B SMP Negeri 15 Tanjungpinang and were selected from as many as eight students. Data collection was done through test techniques and semi-structured interviews. The research findings show that students have different mathematical representation abilities. Students with very high mathematical representation ability categories can master three mathematical representation indicators (visual, mathematical equations or expressions, and written words or text). Students with high categories are only able to master two indicators (visual and mathematical equations or expressions), students with medium categories are only able to master one indicator (visual or mathematical expressions), and students with fewer categories are not able to master all three mathematical representation indicators. The tendency of students to master the indicators of mathematical equations or expressions well is due to being able to use mathematical connection skills well.

Abstract

This study aimed to investigate the mathematical literacy of Grade VIII junior high school students based on their learning styles, as categorized by David Kolb. A qualitative approach with a descriptive research design was employed. The sample consisted of eight students, with two students representing each of the four learning styles: accommodating, assimilating, converging, and diverging. Data were collected through questionnaires, tests, and interviews. The research instruments included the Kolb Learning Style Inventory (KLSI), a mathematical literacy ability test, and an interview guide. Data analysis involved data reduction, data presentation, and conclusion drawing. The results revealed that students with accommodating and assimilating learning styles demonstrated proficiency in all three mathematical literacy indicators—formulate, employ, and interpret/evaluate—whereas students with a converging learning style met only two indicators (formulate and employ). In contrast, students with a diverging learning style fulfilled only one indicator (formulate). These findings suggest that students with accommodating and assimilating learning styles exhibited superior mathematical literacy skills compared to those with converging and diverging learning styles. This study contributes to the understanding of how different learning styles influence students' mathematical literacy and provides insights for educators to develop more effective teaching strategies tailored to diverse learning preferences.

Abstract

Kemampuan berpikir geometri seorang guru menurut Van Hiele berpengaruh signifikan terhadap keberhasilan peserta didik dalam belajar. Kemampuan berpikir geometri mahasiswa calon guru perlu diketahui sejak dini agar upaya perbaikan dapat dilakukan sejak dini pula. Penelitian ini menerapkan pendekatan kualitatif yang bertujuan untuk menganalisis kemampuan berpikir geometri mahasiswa calon guru di Program Studi Pendidikan Matematika UMRAH. Penelitian ini dilakukan terhadap 40 mahasiswa Semester 1 di Program Studi Pendidikan Matematika UMRAH, 3 (tiga) orang diantaranya dipilih sebagai subjek untuk diwawancarai. Teknik pengumpulan data menggunakan teknik tes dan wawancara. Data yang dikumpulkan kemudian dianalis menggunakan teknik analisis kuantitatif dan kualitatif. Hasil penelitian menunjukkan 92,5% mahasiswa calon guru yang diteliti memiliki tingkat kemampuan berpikir geometri Level 2 (analisis), 5% mencapai Level 3 (Deduksi Informal), dan sisanya baru mencapai Level 1 (Visualisasi). Pada level 2, mahasiswa calon guru sudah dapat membedakan pasangan segitiga sebangun, menjelaskan sifat-sifat kesebangunan pada segitiga, dapat mengidentifikasi dan menjelaskan hubungan sudut-sudut dan sisi-sisi bersesuaian pada segitiga sebangun. Namun, mereka gagal dalam menganalisa informasi yang kompleks, dan mengidentifikasi koneksi berbagai informasi relevan yang krusial untuk mencapai kemampuan berpikir geometri Level 3. Berdasarkan hasil penelitian dapat disimpulkan bahwa kemampuan berpikir geometri mahasiswa calon guru di Program Studi Pendidikan Matematika UMRAH masih berada di bawah level yang diharapkan pada peserta didik di Pendidikan Tinggi yaitu Level 4.Abstract The teachers geometric thinking ability according to Van Hiele has a significant effect on students' success in learning geometry. The geometric thinking abilities of preservice teachers need to be identified early so that early interventions can be made. This research uses a qualitative approach which aims to analyze the geometric thinking abilities of preservice teachers studying at the UMRAH Mathematics Education Department in the first semester. This research was conducted on 40 preservice teachers, and three of them were selected as research subjects to be interviewed. Data collection techniques include tests and interviews. The collected data were then analyzed using qualitative analysis techniques. The results show that 92.5% of the preservice teachers examined have a geometric thinking ability at Level 2, 5% at Level 3 (Informal Deduction), and rest only reached Level 1 (Visualization). At Level 2, preservice teachers can distinguish similar triangles, explain the properties of similarity in triangles, and identify and explain the corresponding angles and sides in similar triangles. However, they encounter difficulties in analyzing complex information and identifying connections among various pieces of information crucial for verifying similarity in triangles. Based on the research results, it can be concluded that the geometric thinking abilities of preservicee teacher in the UMRAH Mathematics Education Study Program are still below the level expected for students in higher education, namely Level 4.
