ANALISIS KEMAMPUAN BERPIKIR KRITIS MATEMATIS DAN KREATIF MATEMATIS DALAM PEMECAHAN MASALAH PADA SISWA INTROVERT

Penelitian ini bertujuan untuk menganalisis kemampuan berpikir kritis dan kreatif matematis dalam pemecahan masalah materi barisan dan deret aritmatika pada siswa introvert di kelas XI SMA Xaverius 1 Kota Jambi. Masalah ini muncul karena perbedaan keterampilan berpikir dan proses berpikir siswa berdasarkan tipe kepribadian, yang awalnya ditemukan bahwa kemampuan berpikir kritis dan kreatif matematis rendah pada siswa dengan kepribadian introvert. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan mengumpulkan data angket kepribadian, soal tes, dan wawancara. Subjek penelitian dipilih dari siswa introvert berdasarkan hasil angket kepribadian dan lembar jawaban, dengan tiga siswa yang mewakili keempat kelompok jawaban yang ada. Hasil penelitian menunjukkan bahwa siswa introvert memiliki kemampuan berpikir kritis matematis dalam memahami masalah, merencanakan, dan melaksanakan rencana. Namun, mereka cenderung kurang memeriksa kembali solusi mereka. Kemampuan berpikir kreatif matematis pada siswa introvert terutama mencakup fluency dan flexibility dalam memahami masalah, merencanakan, dan melaksanakan rencana, tetapi kurang dalam hal originality dan elaboration dalam pemecahan masalah. This research aims to analyze critical and creative mathematical thinking skills in solving problems regarding sequences and arithmetic series in introverted students in class XI SMA Xaverius 1 Jambi City. This problem arises because of differences in students' thinking skills and thought processes based on personality type, which was initially found that critical and creative mathematical thinking abilities were low in students with introverted personalities. This research uses a descriptive qualitative approach by collecting personality questionnaire data, test questions and interviews. The research subjects were selected from introverted students based on the results of a personality questionnaire and answer sheet, with three students representing the four answer groups. The research results show that introverted students have mathematical critical thinking skills in understanding problems, planning and implementing plans. However, they tend to check their solutions less. Mathematical creative thinking abilities in introverted students mainly include fluency and flexibility in understanding problems, planning and implementing plans, but lacking in terms of originality and elaboration in problem solving.
