Based on the data of students studying grade XII IPA 1 SMA Negeri 4 Metro in the odd midterm assessment of the 2018/2019 school year obtained an average score of 67 students with only 38.5% of students who were able to exceed KKM. With the number of students consisting of 26 students only 10 students who get grades above KKM. This is still lower than the expected minimum completion criteria of 75. The low learning outcomes are influenced by many factors including the use of improper learning models. One of the models that can improve students' learning outcomes is the Discovery Learning model. The purpose of this study is to improve students' math learning outcomes by using the Discovery Learning model. The percentage of students who scored ≥ 75 in cycles I, II and III was 50%, 69%, and 81% with <br>grade average scores of 70, 72, and 77. This data shows that learning outcomes have been achieved based on the achievement indicator set, which is 75% of students get a score of ≥ 75. So the results of this study show that the learning model of Discovery Learning can improve the results of mathematics learning students of grade XII IPA 1 SMA Negeri 4 Metro.</p> <p>Keywords: discovery learning, learning outcomes</p> 2022-03-28T00:00:00+00:00 Copyright (c) 2020 Epsilon: Jurnal Pendidikan Matematika https://jurnal.stkippgribl.ac.id/index.php/epsilon/article/view/543 MODEL PEMBELAJARAN TREFFINGER MENGGUNAKAN PENDEKATAN KONTEKSTUAL TERHADAP PROSES BELAJAR MATEMATIKA SISWA KELAS X SMK PERSADA 2022-03-28T04:28:34+00:00 Fitriana Rahmawati fitrianarahmawatimath@gmail.com Nurashri Partasiwi nurashripartasiwi@gmail.com <p>Abstract: The problem in this study is "Is there any effect of the Treffinger Learning Model using a contextual approach on the mathematics learning outcomes of class X students in the even semester of SMK Persada Bandar Lampung in the 2018/2019 school year?".
