Learning Outcomes of Transformation Geometry Material for Students of SMP Negeri 8 Banda Aceh Through the Application of the GeoGebra-Assisted Discovery Learning Model

Abstract

This research aims to determine (1) students' mathematics learning outcomes after the GeoGebra-assisted Discovery Learning model was applied to junior high school students, and (2) the comparison of students' mathematics learning outcomes when the GeoGebra-assisted Discovery Learning model was applied compared to conventional learning. This research is quantitative in nature, utilizing a quasi-experimental research design with a pretest-posttest control group format. Sampling was conducted using a random sampling technique. The population in this study consisted of all class IX students at SMP Negeri 8 Banda Aceh, while the sample comprised two classes: class IX-1 as the control group and class IX-3 as the experimental group. The data analysis technique employed was the independent samples t-test. The results of this research show that (1) the final test average of the experimental class was 60.93, with a standard deviation of 15.58, while the control class had a final test average of 47.90, with a standard deviation of 18.28; (2) students' learning outcomes using the GeoGebra-assisted Discovery Learning model are better than those taught with conventional methods, as indicated by the hypothesis test results, where t_count > t_table, or 3.49 > 2.02
