      "abstract": "Kemampuan literasi numerasi siswa di Indonesia masih tergolong rendah, sebagaimana tercermin dari hasil PISA 2022 dengan skor rata-rata sebesar 366. Kondisi ini diperparah oleh dominasi model pembelajaran konvensional yang berpusat pada guru, sehingga siswa kurang terlatih dalam memecahkan masalah matematika secara kontekstual. Penelitian ini bertujuan untuk mengetahui apakah terdapat peningkatan kemampuan memecahkan masalah literasi numerasi siswa melalui penerapan model pembelajaran Inquiry Based Learning (IBL) dengan pendekatan Contextual Teaching and Learning (CTL).\r\nPenelitian ini menggunakan pendekatan kuantitatif dengan desain pre-experimental berbentuk one-group pretest-posttest design. Populasi penelitian adalah seluruh siswa kelas XI SMA Negeri 7 Kediri tahun pelajaran 2025\/2026 yang berjumlah 386 siswa. Sampel diambil menggunakan teknik simple random sampling dan terpilih kelas XI-1 sebanyak 32 siswa. Instrumen penelitian berupa tes uraian pada materi trigonometri yang telah diuji validitas isi (CVI = 1,00) dan reliabilitasnya (Cronbach's Alpha = 0,742). Analisis data dilakukan menggunakan uji normalitas Shapiro-Wilk, uji N-Gain, uji Paired Sample t-test, serta perhitungan effect size Cohen's d.\r\nHasil penelitian menunjukkan bahwa nilai rata-rata pretest sebesar 69,8 meningkat menjadi 82,6 pada posttest. Uji Paired Sample t-test menghasilkan nilai signifikansi < 0,001 (< 0,05) dengan t hitung sebesar 10,984, sehingga H₀ ditolak dan Hₐ diterima. Rata-rata N-Gain diperoleh sebesar 0,3960 yang termasuk kategori sedang, sedangkan effect size Cohen's d sebesar 1,94 tergolong sangat besar. Ketuntasan belajar klasikal meningkat dari 37,5% pada pretest menjadi 87,5% pada posttest, melampaui standar minimal 75%.\r\nBerdasarkan hasil tersebut, dapat disimpulkan bahwa penerapan model pembelajaran Inquiry Based Learning dengan pendekatan Contextual Teaching and Learning secara signifikan meningkatkan kemampuan pemecahan masalah literasi numerasi siswa kelas XI SMA Negeri 7 Kediri pada materi trigonometri.",
