Meningkatkan Hasil Belajar Fisika dengan Menggunakan Alat Peraga Sederhana Pada Materi Suhu dan Kalor Terhadap Siswa di SMK Negeri 1 Lhokseumawe Tahun Pelajaran 2019-2020

This research seeks to ascertain how Class X TE students at SMK Negeri 1 Lhokseumawe can improve their learning outcomes in physics for Temperature and Heat topic using simple visual aids during the even semester of the 2019–2020 academic year. This type of research includes descriptive research with an action research approach. The subjects in this study were students of class X TE of SMK Negeri 1 Lhokseumawe in the academic year 2019/2020, with a total of 28 students. Determination of the subject was obtained based on the results of the investigation of the class to be studied and based on the results of referrals from the Principal. The results of the descriptive analysis revealed that with the following data: Cycle I, the average learning achievement for Physics was 69 with a percentage of completeness of 89%, and in cycle II, the average learning achievement for Mathematics increased to 77 with a percentage of 100%.  The percentage of activeness students in the class are as follows: Cycle I, average percentage of student learning activeness from 56.2% to 84.2%. Therefore, it is possible to draw the conclusion that Class X TE students at SMK Negeri 1 Lhokseumawe's Physics learning outcomes of Temperature and Heat lesson can benefit from simple teaching aids. In order to properly accomplish learning goals, the authors advise teachers to use simple visual aids in Physics lessons, particularly when covering the topic of temperature and heat
