GeoGebra for Geometry

This project aims to understand the effectiveness of the digital tool GeoGebra in teaching the geometrical concepts similarity and congruence to seventh grade students. The prior research in India focused on demonstrations with the availability of minimumal digital resources. This project’s goal is to comprehend whether the digital technology helps students to better visualize of the abstract concepts of mathematics. This research helps to check whether students belonging to different economic and socio-cultural backgrounds can relate to the visualization of geometrical objects shown to them. The findings focused on understanding students’ conceptualization their understanding of similarity and congruence.

After the launch of ICT in formal education environments such as K-12 schools, most of the software companies such as Google, Microsoft, and Apple are coming up with their educational tools. But these applications are very expensive and unaffordable for most of public schools and individuals belonging to under-represented populations. There is a need for free and open software for educational purposes for both teachers and students. GeoGebra was selected because of its easy and free availability. This is one of the few software packages that allows teachers to demonstrate basic to advanced mathematical concepts. There has been no research study done previously in Indian classrooms using GeoGebra for simultaneously teaching the congruence and similarity geometrical concepts to elementary classes.
