Abstract

This study aimed to determine student learning outcomes using the Synectic learning model and learning outcomes using conventional learning models at YAPIM Taruna Dolok Masihul Private High School. The population was all students of class XII SMA which consisted of 2 classes. Samples were taken randomly from 2 classes consisting of the experimental class and the control class. The data observed were chemistry students' learning outcomes, which were collected through a multiple choice test of 20 questions consisting of 5 answer options, which had been tested for validity, reliability, difficulty level and test differentiation. The data obtained were analyzed using the T test, which previously tested the normality and homogeneity of the data. The learning outcomes of the experimental class mean pre-test (27.81 ± 7.21) and post-test mean (76.88 ± 5.70) with an increase in learning outcomes Gain by 68%, while the learning outcomes of the control class average pre-test (22.03 ± 6.70) and the average post-test (70.47 ± 6.00) with an increase in learning outcomes gain by 62%. Hypothesis testing is carried out at the significance level α = 0.05 using one-sided t-test, namely the right side where tcount> ttable (3.05> 1.667139), which means that Ho is rejected and Ha is accepted. By looking at the results of these studies it can be concluded that the chemistry learning outcomes of students who were treated through the application of the Synectic learning model are higher than using conventional teaching.
