    Application of geogebra on euclidean geometry in rural high schools - Grade 11 learners
    (University of Zululand, 2015) Mthethwa, M.Z.; Bayaga, A.
    This research aims to establish the level of students’ cognitive skills using GeoGebra, and investigates whether GeoGebra as a technological tool helps in improving poor performance in respect of Euclidean geometry or geometry of the circle. Students’ interests, in learning about circle geometry in mathematics, are also being tested. GeoGebra is an innovative, dynamic mathematics software which integrates algebra, geometry and calculus to aid students during the learning process. The specific sample in this research consists of 112 Grade 11 secondary school learners within the UMkhanyakude district, Hlabisa circuit, under the Empembeni and Ezibayeni wards. During this research, GeoGebra and the concept of circle geometry were introduced to students. Afterwards, students had to answer several geometry of the circle questions, entailing key theorems as prescribed by the National Mathematics pacesetter for Grade 11 and Grade 12. As students answered the above questions, they solved problems and conducted discussions among themselves. At the end, students were individually required to answer questionnaires which consisted of 15 closed items relating to views on GeoGebra and its impact on Euclidean geometry and mathematics, as well as three open-ended questions which asked learners about their reflections on the application of GeoGebra. The above methods provided a strong base to explore whether GeoGebra as a tool helps students in the learning process. The results showed that students endorsed the use of GeoGebra as a technological tool in the teaching of Euclidean geometry. Some students even suggested that GeoGebra be used in other mathematical topics. Students overall enjoyed the use of GeoGebra, finding it user-friendly and a highly significant learning motivator.
