Abstract

Penelitian ini dilatar belakangi oleh pemanfaatan teknologi yang masih kurang pada bahan ajar sesuai dengan tuntutan kurikulum merdeka yang menuntut peserta didik untuk berpikir kritis dan belajar secara mandiri, sehingga membuat peserta didik kesulitan dalam memahami materi pembelajaran, khususnya materi sistem persamaan linear tiga variabel. Penelitian ini bertujuan untuk menghasilkan E-LKPD valid dan praktis pada materi sistem persamaan linear tiga variabel.Penelitian ini merupakan jenis penelitian pengembangan R&D (Research and Development) dengan menggunakan model pengembangan ADDIE (Analyze, Design, Development, Implementation, Evaluation). Produk yang dikembangkan berupa E-LKPD berbasis Problem Based Learning (PBL) pada materi sistem persamaan linear tiga variabel. Subjek penelitian ini adalah siswa kelas X Fase E MAN 3 Pasaman Barat. Instrumen yang digunakan dalam penelitian ini berupa lembar validasi dan lembar uji praktikalitas.Berdasarkan hasil validitas E-LKPD oleh validator ahli media dan ahli materi diperoleh persentase penilaian akhir kevalidan E-LKPD 90,14% dengan kategori sangat valid. Nilai kepraktisan dengan pendidik memperoleh nilai akhir 86,66% dengan kategori sangat praktis dan nilai akhir uji praktikalitas peserta didik diperoleh persentase 86,28% dengan kategori sangat praktis. Berdasarkan hasil penelitian dapat disimpulkan bahwa E-LKPD berbasis Problem Based Learning (PBL) pada Materi Sistem Persamaan Linear Variabel Kelas X Fase E MAN 3 Pasaman Barat dinyatakan valid dan praktis untuk digunakan oleh pendidik dan peserta didik.

Abstract

This study was motivated by the low mathematical problem-solving ability of high school students. The purpose of this research was to determine the differences in mathematical problem-solving ability between students who received instruction through the Realistic Mathematics Education (RME) approach and those who experienced conventional learning in Grade XII Phase F of SMAN 2 Lubuk Sikaping, Pasaman Regency. The research employed an experimental method with a Control Group Posttest Only design. The population consisted of all Grade XII Phase F students in the 2025/2026 academic year. Samples were selected using random sampling, resulting in Grade XII F 8 as the experimental class and Grade XII F 7 as the control class. The research instrument was a problem-solving test in essay form, based on Polya’s problem-solving steps, which had been validated and showed a reliability coefficient of 0.855. Data analysis was carried out using a one-tailed t-test at a 5% significance level. The results indicated that the mathematical problem-solving ability of students taught with the RME approach was significantly higher than that of students taught through conventional learning. This finding suggests that RME provides contextual learning experiences, encourages active participation, and fosters critical, analytical, and creative thinking skills in solving mathematical problems. Therefore, RME can be recommended as an alternative instructional strategy to enhance the quality of mathematics teaching and learning in secondary schools.
