Abstract

Penelitian ini bertujuan untuk menganalisis kemampuan berpikir fleksibel matematis siswa dalam menyelesaikan soal matematika pada materi perbandingan ditinjau dari attitudes toward mathematics. Penelitian ini merupakan penelitian kualitatif dengan metode deskripsif. Teknik pengumpulan data dalam penelitian melalui penyebaran angket attitudes toward mathematics, tes kemampuan berpikir fleksibel matematis, dan wawancara. Instrumen yang digunakan yaitu peneliti sendiri sebagai instrumen utama dan instrumen pendukung berupa angket attitudes toward mathematics dan soal tes kemampuan berpikir fleksibel dalam soal uraian dengan materi perbandingan. Subjek penelitian ini terdiri dari 2 siswa kelas VII-A SMP Negeri 3 Tasikmalaya yang dipilih berdasarkan pertimbangan, yaitu siswa yang menunjukan kategori konsisten pada hasil angket atttitudes toward mathematics, dan siswa yang memiliki skor attitudes toward mathematics yang paling dominan serta yang paling banyak memenuhi indikator kemampuan berpikir fleksibel tanpa memperhatikan kebenaran jawaban mereka pada setiap kategori attitudes toward mathematics. Teknik analisis data yang digunakan meliputi reduksi data, penyajian data, dan penarikan kesimpulan. Berdasarkan hasil penelitian ditemukan bahwa siswa dengan attitudes toward mathematics yang positif  mampu menyelesaiakan soal melalui seluruh indikator kemampuan berpikir fleksibel, yaitu mengubah perspektif, mempertimbangkan opsi, dan menghasilkan alternatif, sementara siswa dengan attitudes toward mathematics yang negatif hanya mampu menyelesaikan soal melalui dua indikator kemampuan berpikir fleksibel saja yaitu mengubah perspektif, dan mempertimbangkan opsi.

Abstract

This study aims to describe students' mathematical representation abilities in terms of Adversity Quotient (AQ). The study used a qualitative method with a descriptive approach. Four students of grade XI MIPA MA Serba Bakti were selected purposively based on the results of the AQ questionnaire to represent the categories of Climbers, Campers–Climbers, Campers, and Quitters–Campers. The research instruments were an AQ questionnaire, a mathematical representation ability test, and a validated interview. Data were analyzed using the Miles and Huberman model which includes data reduction, data presentation, and conclusion drawing. The results showed that the higher the AQ category, the more complete, detailed, and correct the mathematical representation produced. Conversely, the lower the AQ category, the mathematical representation tends to be incomplete, incoherent, or produce incorrect answers. This finding confirms the relationship between AQ and mathematical representation abilities. Theoretically, this study strengthens the study of the role of non-cognitive factors in mathematics learning, while pedagogically its implications encourage teachers to consider AQ factors in designing learning strategies.

Abstract

This study was motivated by students’ mathematical literacy levels that have not yet met expected learning standards and by the limited use of interactive learning media in schools. In addition, studies that combine learning models and digital media to improve students’ mathematical literacy remain limited. This study aimed to examine the effectiveness of a joyful learning model supported by Scratch-based learning media in improving students’ mathematical literacy, as well as to describe students’ mathematical literacy performance, learning activities, and responses during the implementation. The study employed a one-shot case study experimental design. The population comprised all seventh-grade students at SMP Negeri 10 Tasikmalaya, and the sample was Class VII K (n = 32), selected through simple random sampling. Data were collected using a mathematical literacy test, a learning activity observation sheet, and a student response questionnaire. The data were analyzed using a binomial (proportion) test. The results indicated that the joyful learning model supported by Scratch-based media was effective for students’ mathematical literacy, with students’ mathematical literacy categorized as moderate (71.9%). Student learning activities were classified as very good, and students’ responses to the learning were very positive.
