Abstract

Abstrak : Tujuan penelitian ini adalah mendeskripsikan cara peserta didik dalam menyelesaikan soal berbentuk literasi matematis dan tingkat kemampuan literasi matematis peserta didik ditinjau dari self confidence pada materi aritmatika sosial kelas VII. Penelitian ini menggunakan pendekatan kualitatif dengan jenis kualitatif deskriptif. Subjek penelitian ini adalah enam peserta didik kelas VII SMP Negeri 03 Batu. Instrumen penelitian ini menggunakan angket, soal tes, pedoman wawancara, dan lembar dokumentasi. Berdasarkan hasil analisis data diperoleh kesimpulan sebagai berikut. 1) Terdapat beberapa cara peserta didik dalam menyelesaikan soal literasi matematis ditinjau dari self confidence pada materi Aritmatika Sosial kelas VII, yaitu: a) peserta didik dengan kemampuan literasi matematis tinggi mampu memenuhi semua indikator kemampuan literasi matematis yaitu merumuskan, menerapkan, dan menafsirkan. b) peserta didik dengan kemampuan literasi matematis sedang memenuhi dua dari tiga indikator kemampuan literasi matematis yaitu indikator merumuskan dan menerapkan, dan c) peserta didik dengan kemampuan literasi matematis rendah hanya mampu memenuhi indikator kemampuan literasi matematis yaitu merumuskan. 2) Tingkat kemampuan literasi matematis peserta didik ditinjau dari self confidence pada materi Aritmatika Sosial kelas VII, yaitu: a) tingkat kemampuan literasi matematis tinggi terdapat pada dua peserta didik atau setara dengan 33,3% dan memperoleh hasil rata-rata nilai 87,5; b) tingkat kemampuan literasi matematis sedang terdapat pada dua peserta didik atau setara dengan 33,3% dan memperoleh hasil rata-rata nilai 71,5; dan c) tingkat kemampuan literasi matematis rendah terdapat pada dua peserta didik atau setara dengan 33,3% dan memperoleh hasil rata-rata nilai 48,5.Kata kunci: Kemampuan Literasi Matematis, Self Confidence, Aritmatika Sosial

Abstract

The student selection process through the Recognition of Prior Learning (RPL) pathway continues to face challenges related to objectivity and transparency, particularly in integrating qualitative and quantitative data from various assessment instruments such as interviews and problem-solving tests. This study aims to develop a decision support system based on the Mamdani-type fuzzy logic to support a fair and standardized RPL student selection process. A quantitative approach was employed through intelligent system modeling, with system implementation carried out using Microsoft Excel by modifying IF-THEN formulas to simulate fuzzy logic principles. The system incorporates two input variables interview scores and problem-solving test scores and one output variable representing admission eligibility, categorized into five levels (A-E). Testing on a sample of ten prospective students showed that the system was able to perform systematic evaluations and generate more objective and consistent admission decisions. The conclusion of this study is that the application of a fuzzy inference system can improve the quality of decision making in the selection of RPL students, as well as support the principles of competency based and fair assessment.

Abstract

Mathematical communication skills and creative thinking are two essential aspects of mathematics learning; however, studies examining how creative thinking is manifested within mathematical communication remain limited. This study aims to describe how creative thinking is manifested in students’ mathematical communication when solving two-dimensional geometry problems from a commognitive perspective. This research employed a qualitative approach with a single-case study design. The research subject was one student who demonstrated a variety of strategies in solving contextual dua dimensi geometry problems. Data were collected through written tasks and semi-structured interviews, and were analyzed based on the components of commognitive discourse, namely the use of mathematical terms, visual representations, argumentative narratives, and solution patterns. The findings indicate that creative thinking is manifested through variations in representation, flexibility of strategies, originality in constructing arguments, and elaboration of mathematical explanations. These findings suggest that creativity can be identified through the structure of students’ mathematical communication and contribute theoretically to the integration of creativity within mathematical discourse analysis.
