THE EFFECT OF STUDENT LEARNING OUTCOMES ON TEMPERATURE AND HEAT MATERIAL USING THE DISCOVERY LEARNING MODEL

Abstract

This study aims to determine the effect of the discovery learning model on learning outcomes in the material Temperature and Heat in class XI SMAN 1 Sibolangit T.P 2022/2023. The type of research used is a quasi experiment. The population in this study were all students of class XI SMA N 1 Sibolangit. Sampling was done by cluster random sampling by taking 2 classes out of 6 classes randomly, namely XI MIA 3 as the control class, totaling 30 people and XI MIA 2 as the experimental class, totaling 32 people. The instrument used to determine student learning outcomes is a student learning outcomes test. In testing the normality of the pretest values in the experimental class, it was obtained Lcount < Ltable, so the data for both classes were normally distributed. In the homogeneity test obtained Fcount <Ftable, then both samples come from homogeneous groups. Then given a different treatment, the experimental class with the discovery learning model and the control class with conventional learning. After learning was given, the average value of the posttest experimental class was higher than the average value of the control class. The results of the t test obtained tcount > ttable, so ha was accepted. Thus, it was found that there was an influence of the discovery learning model on student learning outcomes in the subject of temperature and heat in class XI SMAN 1 Sibolangit T.P 2022/2023.
