Abstract

This study describes students’ thinking processes in solving inverse proportion problems based on mathematical ability. The study employed a qualitative descriptive design involving three students categorized as having high, moderate, and low mathematical ability. Data were collected through a written inverse proportion task and task-based interviews organized according to four problem-solving stages: understanding the problem, devising a plan, carrying out the plan, and looking back. The task asked students to determine the completion time when 20 workers who could finish a job in 30 days were increased to 50 workers. The results showed that the high-ability student recognized the inverse relation, used the constant-product model 20 × 30 = 50 × x, obtained 12 days, and verified the answer. The moderate-ability student treated the situation as direct proportion by writing 20 : 50 = 30 : x, indicating relational misconception. The low-ability student recognized the inverse relation but had difficulty with multiplication and division and did not check the answer. The findings imply that inverse proportion instruction should emphasize contextual relations, strategy selection, computational fluency, and reflective checking.

Abstract

PLP I memberi mahasiswa calon guru matematika pengalaman awal untuk memahami kehidupan sekolah secara nyata. Artikel ini mendeskripsikan pelaksanaan PLP I di SMA Muhammadiyah Boarding School Kota Gorontalo dengan fokus pada kultur sekolah, kompetensi guru, karakteristik peserta didik, implementasi Kurikulum Merdeka, dan pembelajaran mendalam. Penelitian menggunakan pendekatan deskriptif kualitatif melalui observasi, wawancara, dokumentasi, dan catatan lapangan pada 4-18 Mei 2026. Hasil penelitian menunjukkan bahwa sekolah memiliki kultur religius, disiplin, ramah, dan kekeluargaan melalui pembiasaan 3S, doa bersama, salat berjamaah, apel pagi, dan nilai 5K. Guru matematika menunjukkan kompetensi profesional, pedagogik, sosial, dan kepribadian melalui penguasaan materi, pengelolaan kelas, media digital, dan pembelajaran berpusat pada siswa. Wawancara menunjukkan bahwa pembelajaran mendalam diterapkan melalui masalah kontekstual, pertanyaan pemantik, diskusi, presentasi, dan refleksi. PLP I memperkuat pemahaman calon guru tentang praktik keguruan, kultur sekolah, dan pembelajaran matematika bermakna di boarding school.
