Abstract

Penelitian ini bertujuan untuk mengetahui kemampuan representasi matematis siswa yang diajarkan dengan model pembelajaran Student Facilitator and Explaining (SFE) dengan media LKPD lebih baik dibandingkan dengan siswa yang diajarkan menggunakan model pembelajaran langsung di SMPN 7 Mataram. Metode penelitian yang digunakan adalah quasi-experimental design dengan posttest-only control group design. Populasi penelitian siswa kelas VIII SMPN 7 Mataram, sampel penelitian kelas VIII-J sebanyak 42 siswa sebagai kelas eksperimen dan VIII-I  sebanyak 42 siswa sebagai kelas kontrol yang dipilih melalui teknik purposive sampling. Kelas eksperimen mendapatkan pembelajaran menggunakan model pembelajaran SFE, sedangkan kelas kontrol menggunakan model pembelajaran langsung. Teknik pengumpulan data menggunakan tes kemampuan representasi matematis. Hasil uji-t menunjukkan bahwa  diterima, yang berarti rata-rata kemampuan representasi matematis kelas eksperimen lebih baik dari rata-rata kemampuan representasi matematis kelas kontrol. Selain itu, rata-rata hasil belajar siswa di kelas eksperimen juga lebih tinggi, dan terdapat peningkatan sikap positif yang lebih tinggi pada siswa di kelas eksperimen. Hal ini menunjukkan bahwa kemampuan representasi matematis siswa yang diajarkan dengan model pembelajaran Student Facilitator and Explaining (SFE) dengan media LKPD lebih baik dibandingkan dengan siswa yang diajarkan menggunakan model pembelajaran langsung di SMPN 7 Mataram Tahun Ajaran 2024/2025.This study aims to determine whether the mathematical representation ability of students taught using the Student Facilitator and Explaining (SFE) learning model with LKPD media is better than that of students taught using the direct instruction model at SMPN 7 Mataram. The research method used is a quasi-experimental design with a posttest-only control group design. The population consisted of eighth-grade students at SMPN 7 Mataram, with the sample comprising 42 students from class VIII-J as the experimental group and 42 students from class VIII-I as the control group, selected through purposive sampling. The experimental class was taught using the SFE learning model, while the control class received direct instruction. Data were collected through a mathematical representation ability test. The results of the t-test showed that ​, namely 7.04002 > 1.664, indicating that  was accepted. This means that the average mathematical representation ability of the experimental class was higher than that of the control class. Based on these results, it can be concluded that students who received instruction using the SFE model had better mathematical representation abilities compared to those who received direct instruction.
