Abstract

This article discusses the use of GeoGebra as a tool in learning Systems of Linear Equations in Two Variables (SPLDV). GeoGebra, created by Markus Hohenwarter in 2001, has grown to become one of the most popular educational tools worldwide, allowing students and teachers to explore mathematical concepts visually and interactively. With features such as graph generation, mathematical object manipulation, and intersection analysis, GeoGebra facilitates a deeper understanding of SPLDV. The purpose of this article is to explain how using GeoGebra can simplify the learning process for Systems of Linear Equations in Two Variables (SPLDV). The research methodology used includes qualitative and quantitative approaches, by measuring student understanding before and after using GeoGebra. The research results show that GeoGebra not only improves understanding of mathematical concepts, but also develops students' problem solving and critical thinking skills. Thus, GeoGebra contributes significantly to improving the quality of mathematics teaching and learning.

Abstract

The critical problem in this research is the lack of instructional strategies that simultaneously enhance literacy and numeracy skills while addressing students' diverse learning needs. While the Problem Based Learning model fosters problem-solving, its implementation often overlooks individual differences, making its integration with differentiated instruction crucial and challenging. One of the mathematical skills that students must have is literacy numeracy skills. However, based on initial observations at one of the public senior high schools in Kuningan, students' literacy and numeracy abilities are still low. This study aims to examine the effectiveness of the Integrated Problem Based Learning Differentiated Instruction model in improving high school students’ literacy and numeracy skills. The research employed an experimental method with a one-group pre-test and post-test design involving 36 class XI students. Data were collected through literacy numeracy tests administered before and after the intervention. Data analysis was conducted using N-gain to measure the improvement in students' literacy numeracy ability. The research results were obtained from test results N-Gain, with scores of 0.56 (medium category) and an increase percentage of 56.05%. Students show better abilities in understanding, interpreting, and analyzing problem-based questions related to mathematical concepts
