Abstract

Abstrak. Kemampuan berpikir kritis siswa dalam pembelajaran sangat penting dimiliki siswa. Penelitian ini bertujuan untuk mendeskripsikan kemampuan berpikir kritis dalam memecahkan masalah matematis ditinjau dari gaya kognitif reflektif dan implusif. Jenis penelitian ini menggunakan penelitian kualitatif dengan metode yang digunakan adalah deskriptif dengan bentuk studi kasus. Subjek penelitian ini yaitu 2 siswa dari kelas VII G SMP Bruder Pontianak yang terdiri dari 1 subjek reflektif dan 1 subjek impulsif, dimana diambil berdasarkan pertimbangan dan saran dari guru mata pelajaran. Subjek dipilih dengan menggunakan teknik purposive sampling. Teknik pengumpulan data yang digunakan adalah tes instrumen Matching Familiar Figure Test (MFFT), soal tes essay kemampuan berpikir kritis dalam memecahkan masalah matematis, dan angket serta non tes berupa wawancara dan dokumentasi. Untuk menguji keabsahan data digunakan triangulasi teknik. Analisis data dilakukan dengan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil tes dan wawancara dianalisis berdasarkan indikator kemampuan berpikir kritis yaitu: interpretasi, analisis, evaluasi, dan inferensi. Hasil ini menunjukkan bahwa siswa yang bergaya kognitif reflektif mampu memenuhi semua indikator berpikir kritis interpretasi, analisis, evaluasi dan inferensi dalam menyelesaikan soal tes berpikir kritis cenderung tuntas, mengambil lama dan jawabannya kebanyakan benar sehingga berpikir kritis tinggi. Siswa yang bergaya kognitif implusif hanya mampu memenuhi sebagian dari semua indikator berpikir kritis interpretasi, analisis, evaluasi dan inferensi, yaitu interpretasi, evaluasi dan inferensi dari indikator yang terpenuhi akan tetapi jawabannya dalam menyelesaikan soal tes berpikir kritis cenderung kurang tepat, mengambil cepat dan jawabannya kebanyakan salah sehingga berpikir kritis rendah.Kata kunci: Kemampuan Berpikir Kritis; Memecahkan Masalah; Gaya Kognitif

Abstract

This study aims to determine the learning obstacles associated with the triangle material and the factors that cause it. The participants in this study were class VIII students of SMPN 1 Sengah Temila and mathematics teachers. This study uses a qualitative method. Data collection techniques in this research used observation, measurement techniques (tests), interviews, and documentary studies. The data was analyzed qualitatively to determine students' learning obstacles in class VIII triangle material at SMPN 1 Sengah Temila. The results of this study are that students experience ontogenic barriers, namely obstacles related to one's mental readiness, epistemological, namely students' knowledge that has a limited context, and didactical obstacles related to teaching materials, or learning offerings used by the teacher. The obstacles experienced by students are learning obstacles to types of triangles, determining triangle images and triangle concepts.

Abstract

Penelitian ini bertujuan untuk menghasilkan sebuah learning trajectory (alur belajar) mahasiswa pada mata kuliah Perencanaan Pengajaran Matematika (PPM) sebagai upaya pengembangan kompetensi pedagogik mahasiswa calon guru matematika dalam menyusun perangkat pembelajaran matematika. Penelitian ini merupakan penelitian desain didaktis (Didactical Design Research) yang memuat tiga tahapan analisis, yaitu analisis prospektif, analisis metapedadidaktik, dan analisis retrospektif. Subjek dalam penelitian ini adalah mahasiswa calon guru matematika, yakni mahasiswa semester IV Program Studi Pendidikan Matematika IKIP PGRI Pontianak yang sedang menempuh mata kuliah PPM. Hasil penelitian ini menunjukkan bahwa: (1) pada tahap analisis prospektif diperoleh hasil analisis tentang gambaran pengetahuan awal mahasiswa dan gambaran situasi pembelajaran PPM yang menjadi dasar dalam merumuskan lintasan belajar hipotetik/hypothetical learning trajectory (HLT); (2) pada tahap analisis metapedadidaktik diperoleh hasil analisis implementasi HLT terhadap kemampuan mahasiswa dalam menyusun perangkat pembelajaran berupa program tahunan, program semester, silabus, HLT Siswa, desain didaktis hipotetik yang dilengkapi dengan prediksi respon dan antisipasi didaktik pedagogik, serta media pembelajaran; dan (3) pada tahap analisis retrospektif diperoleh hasil analisis refleksi dan evaluasi terhadap HLT yang telah diimplementasikan sehingga diperoleh learning trajectory. Dengan demikian, melalui penelitian desain didaktis telah diperoleh sebuah learning trajectory untuk membantu mahasiswa dalam melakukan pengembangan kompetensi pedagogik, sekaligus learning trajectory ini menjadi dasar dalam merumuskan desain pembelajaran berupa bahan ajar PPM pada penelitian selanjutnya.

Abstract

This study aims to explore the mathematical concepts embedded in the traditional farming tools of the Dayak Kayong community and their relationship to strengthening contextual mathematics learning in Randau Village. The study is motivated by the importance of connecting mathematics learning with local culture so that learning becomes more meaningful and relevant for students. An ethnomathematical approach is employed to reveal mathematical concepts found in the activities and traditional tools of the Dayak Kayong farming community.The research method used is descriptive with a qualitative ethnographic approach. The research subjects include traditional leaders, traditional tool craftsmen, and farmers in Laman Kumai Hamlet, Randau Village. Data were collected through observation, interviews, and documentation, then analyzed qualitatively through data reduction, data presentation, and conclusion drawing, with triangulation used to ensure data validity.The results show that traditional tools such as canting (gantang), tanggui, and lesung contain mathematical concepts including plane figures, solid figures, measurement, number patterns, and geometry. These concepts have the potential to be integrated into contextual mathematics learning as learning resources that help improve conceptual understanding, increase learning motivation, and foster appreciation for local culture.Therefore, the traditional farming tools of the Dayak Kayong community possess ethnomathematical values that are relevant to be utilized in contextual mathematics learning.

Abstract

This study investigates the effect of Claude AI-assisted assessment with a purpose-built adaptive prompt system on reducing mathematics anxiety among university students in Abstract Algebra. Mathematics anxiety—a multidimensional affective construct distinct from general anxiety and from the cognitive barriers addressed in prior research on mathematical representation—constitutes a significant impediment to learning advanced mathematics. The study employed a mixed-methods design with an embedded experimental model involving 26 fourth-semester students of the Mathematics Education Study Program at Universitas PGRI Pontianak during the 2024/2025 academic year. The primary instrument was the Mathematics Anxiety Rating Scale–Revised (MARS-R) adapted into Indonesian and psychometrically validated (Cronbach's α = .91, CFI = .96). The Claude AI system was engineered with six adaptive prompt types—Calming Prompt, Stepwise Scaffolding, Positive Affirmation, Misconception Diagnosis, Metacognitive Reflection, and Progressive Feedback—automatically selected based on detected anxiety profiles. Results showed a highly significant reduction in mathematics anxiety (Z = −4.41, p < .001, r = .86). Mean scores declined from 46.7 (high) to 30.3 (low), a 35.1% reduction. The previously strong negative anxiety–achievement correlation (r = −.67, p < .001) became non-significant post-intervention (r = −.38, p = .054), indicating successful anxiety decoupling. These findings contribute to understanding affective dimensions in advanced mathematics learning and establish an empirical basis for adaptive AI in academic anxiety management.
