How effective is GeoGebra Software in improving students learning similarities of geometrical shapes

The teaching and learning of geometry are changing due to the wide range of software and mobile applications that instructors can incorporate into their classes. Some students struggle with visualizing geometric shapes and related concepts, which affects their performances. GeoGebra, which is an open-source dynamic mathematical software, can enhance students' visualization and hence their learning of geometrical concepts. This study investigated the impact of using GeoGebra in teaching geometry specifically, the similarities of triangles concept, to first-year Landscape Engineering students enrolled in the "Mathematics for Built Environment" course at the University of Bahrain. The study was conducted on 38 students enrolled in the course. The research data were obtained from students' pre and post test results. The collected data were analyzed, and the results showed that GeoGebra was an effective tool for enhancing students learning and understanding of similarities of triangles concepts.
