Abstract

Critical thinking skills are essential competencies in mathematics learning, but learning practices often emphasize final results rather than students' thinking processes. These differences in thinking processes are inseparable from personality characteristics, particularly the Thinking and Feeling types. This study aims to describe and compare students' critical thinking skills in solving mathematical problems based on the Thinking and Feeling personality types. This study uses a descriptive qualitative approach with two subjects, eighth-grade students at Unismuh Makassar Junior High School, each representing the Thinking and Feeling personality types. Data were obtained through the MBTI personality test, critical thinking ability tests in the form of essay questions, semi-structured interviews, and documentation, then analyzed using the Miles, Huberman, and Saldaña model with time triangulation to ensure data validity. The results showed that both personality types were able to fulfill the six indicators of critical thinking, namely interpretation, analysis, inference, evaluation, explanation, and self-regulation, but through different thinking processes. Students with the Thinking type showed a more logical, systematic, and efficient thinking pattern from the early stages, while students with the Feeling type displayed a more gradual, contextual, and reflective thinking process. These findings confirm that critical thinking in mathematics is multidimensional and influenced by personality. This study contributes to enriching the study of mathematical critical thinking and provides practical implications for teachers to design adaptive learning according to students' thinking characteristics.

Abstract

Penelitian ini bertujuan untuk mengetahui efektivitas pembelajaran matematika melalui penerapan model kooperatif tipe Auditory Intellectually Repetition (AIR) pada siswa kelas VIII SMP Unismuh Makassar. Penelitian ini merupakan penelitian pra-eksperimen dengan desain One Group Pretest–Posttest Design. Sampel penelitian berjumlah 17 siswa yang dipilih menggunakan teknik simple random sampling. Instrumen penelitian meliputi tes hasil belajar, lembar observasi aktivitas siswa, dan angket respons siswa. Data dianalisis menggunakan statistik deskriptif dan inferensial melalui uji Shapiro–Wilk dan One Sample t-test. Hasil penelitian menunjukkan bahwa rata-rata nilai pretest meningkat dari 10,29 menjadi 77,59 pada posttest, dengan rata-rata N-Gain sebesar 0,7503 (kategori tinggi). Ketuntasan belajar klasikal mencapai 82,35%, aktivitas siswa sebesar 90,23% (kategori sangat baik), dan respons siswa sebesar 79,78% (kategori positif). Berdasarkan hasil tersebut, penerapan model pembelajaran kooperatif tipe Auditory Intellectually Repetition (AIR) efektif diterapkan pada pembelajaran matematika materi Teorema Pythagoras di kelas VIII SMP Unismuh Makassar.
