Abstract

Penelitian ini bertujuan untuk menghasilkan Local Instruction Theory (LIT) menggunakan strategi mathematical modeling untuk meningkatkan kemampuan pemecahan masalah mahasiswa calon guru Sekolah Dasar (SD). Metode yang digunakan dalam penelitian ini adalah Design Research yang dikembangkan oleh Gravemeijer dengan tahapan: preliminary design, teaching experiment, dan restrospective analysis. Subjek penelitian ini sebanyak 12 mahasiswa semester 7 angkatan 2021/2022 untuk mengetahui kemampuan awal pemecahan masalah matematika. Pada teaching experiment melibatkan 72 mahasiswa angkatan 2022/2023 dengan rincian 37 mahasiswa pada siklus I dan sebanyak 35 mahasiswa pada siklus II. Masing-masing siklus dilaksanakan selama 5 pertemuan dengan dilengkapi instrumen yang digunakan mencakup Hypothetical Learning Trajectory (HLT) sebagai panduan pembelajaran, Lembar Kegiatan Mahasiswa, serta modul pemecahan masalah yang membantu mahasiswa selama proses belajar. Hasil penelitian menunjukkan bahwa: 1) kemampuan awal pemecahan masalah mahasiswa calon guru SD masih kurang optimal dikarenakan dari data 12 mahasiswa yang mengerjakan soal kemampuan pemecahan masalah, hanya 5 mahasiswa yang mampu menyusun strategi pemecahan masalah, dan 4 diantaranya mampu mengecek kembali jawaban dengan teliti; 2) Rancangan awal LIT yang disusun dimulai tentang konsep pecahan, operasi hitung pecahan, perbandingan, persen, dan pemecahan masalah dalam menyelesaikan konsep pecahan; 3) Rancangan akhir LIT disusun berdasarkan hasil refleksi terhadap rancangan awal dengan memperbarui bahasa pada soal dan menambahkan antisipasi dosen untuk mengakomodasi berbagai kemungkinan respons mahasiswa yang lain antisipasi yang dilakukan oleh dosen karena pada rancangan sebelumnya ditemukan beberapa respons mahasiswa yang kurang sesuai dengan prediksi; dan 4) Kemampuan akhir pemecahan masalah mahasiswa calon Guru SD meningkat setelah mengikuti serangkaian aktivitas pembelajaran. Kata kunci: Local Instructional Theory, pecahan, pemecahan masalah, mathematical modeling, mahasiswa calon guru SD This study aims to produce Local Instruction Theory (LIT) using mathematical modeling strategy to improve problem solving ability of elementary school teacher candidate students. The method used in this study is Design Research developed by Gravemeijer with the following stages: preliminary design, teaching experiment, and retrospective analysis. The subjects of this study were 12 7th semester students of the 2021/2022 intake to determine their initial mathematical problem solving ability. The teaching experiment involved 72 students of the 2022/2023 intake with details of 37 students in cycle I and 35 students in cycle II. Each cycle was carried out for 5 meetings equipped with instruments used including Hypothetical Learning Trajectory (HLT) as a learning guide, Student Activity Sheets, and problem solving modules that help students during the learning process. The results of the study indicate that: 1) the initial problem-solving ability of prospective elementary school teachers is still less than optimal because from the data of 12 students who worked on the problem-solving ability questions, only 5 students were able to develop problem-solving strategies, and 4 of them were able to re-check their answers carefully; 2) The initial design of the LIT that was prepared began with the concept of fractions, fractional arithmetic operations, comparisons, percentages, and problem solving in solving the concept of fractions; 3) The final design of the LIT was prepared based on the results of reflection on the initial design by updating the language in the questions and adding lecturer anticipation to accommodate various other possible student responses; anticipation carried out by the lecturer because in the previous design several student responses were found to be less in accordance with predictions; and 4) The final problem-solving ability of prospective elementary school teachers increased after participating in a series of learning activities. Keywords: Local Instructional Theory, fractions, problem solving, mathematical modeling, prospective elementary school teachers
