Pengaruh Media Powerpoint-GeoGebra Terhadap Hasil Belajar Persamaan Linier Siswa di SATAP 4 Gunungsari

Abstract

The low scores of students in the Mathematics End-of-Semester Summative Assessment are due to the suboptimal use of learning media, especially digital-based media. This research aims to determine the effect of PowerPoint media assisted by GeoGebra on the learning outcomes of eighth-grade students in One-Variable Linear Equation material. This research is classified as quantitative research, using a one-group pre-test and post-test design. The subjects of study were all eighth-grade students, consisting of 17 individuals. The research instruments used were pre-test and post-test questions with the Wilcoxon signed-rank test analysis method. The results showed that students’ learning outcomes after learning using PowerPoint assisted by GeoGebra obtained an average pre-test score of 47.3 and an average post-test score of 56.2. This indicates a fairly significant improvement. The use of PowerPoint media made students more focused on observing classroom learning and increased their enthusiasm for learning. GeoGebra helped students understand the graphical form of one-variable linear equation solutions and helped them validate the answers they had calculated independently using known solution rules. Thus, it can be concluded that the use of PowerPoint media assisted by GeoGebra affects the mathematics learning outcomes of eighth-grade students in mathematics learning on one-variable linear equation material.
