![]() Two schools formed the control groups and one school was the experimental group. The sample was 94 Grade 9 students from three secondary schools in a province in South Africa. The non-equivalent control group pre-test-post-test quasi-experimental research design was used in the study. These aspects of linear functions tend to pose a challenge to many students. The purpose of this study was to explore the effectiveness of GeoGebra assisted instruction on students’ achievement in drawing graphs of linear functions and interpretation of the representations of linear functions. The findings extend current research on students' representational competence by bringing attention to the role of students' generation of improvised representations in the processes of learning with and about representations. During this sense-making process, students improvised their own representations to make their ideas more explicit. This study shows that specific features of the simulation features connected with microscopic aspects of friction-triggered students to ask what-if and why questions and consequently, to learn about the representation. Our analysis is based on the assumption that, in a collaborative learning environment, students use their bodies as means of dealing with interpretational problems, and that exploring students' gestures and enactment can be used to analyse their sensemaking processes. We present and analyse video data of upper-secondary school students' interaction with a GeoGebra simulation of friction. gestures, enactment) of students' interaction and constructions of representations in relation to a digital learning environment. The present study contributes to the understanding of physics students' representational competence by examining specific bodily practices (e.g. Each key feature of GeoGebra is thoroughly analyzed, and further analyses, along with how GeoGebra can be helpful in different topics, are discussed. Therefore, this study shows the effec-tiveness of GeoGebra and its MVP key features in science and engineering, particularly in topics related to mathe-matics. We also show how integrating GeoGebra into the learning scheme can help improve the skills and knowledge of school and university students in numerous advanced mathematical courses, such as calcu-lus, mathematical statistics, linear algebra, linear programming, computer-aided design, computer-aided geomet-ric design, analytic and projective geometry, and graphical representation. In this study, we dis-cuss how GeoGebra provides an environment for learning that is very interactive and collaborative between the learner and the instructor. Many studies have shown the positive effects of GeoGebra on the efficiency and effectiveness of learning and teaching topics related to science, technology, engineering, and mathematics. ![]() GeoGebra employs the synthesis of three key features: modeling, visualization, and programming (MVP). Its dynamic interface allows its users to accurately and interactively visualize their work, models, and results. ![]() If you want your students to think more critically and become more self-autonomous learners of mathematics, and if you want your STUDENTS to be at the center of their learning vs.GeoGebra is an interactive geometry, algebra, statistics, and calculus application designed for teaching and learn-ing math, science, and engineering. We will also learn how to use these two apps to engage students in active, student-centered, discovery-based learning experiences. Best of all, GeoGebra is FREE! In this course, we will quickly explore all four GeoGebra apps (Graphing Calculator, Geometry, 3D Graphing Calculator, Classic) and will learn how to effectively use the tools specifically within the Graphing Calculator and Geometry apps. Students can use GeoGebra to construct, analyze phenomena, make conjectures, test those conjectures, and conceptually discover new knowledge. Over 100 million students and teachers (from all six habitable continents) use GeoGebra to actively engage in the journey of discovering mathematics. GeoGebra is the world’s leading dynamic mathematics platform.
