Effectiveness of Geogebra in Teaching and Learning Geometry

Abstract

This study entitled “Effectiveness of GeoGebra in teaching and learning geometry” is an experimental research. The first objective of this study were to compare the achievement of students taught by using GeoGebra both by teacher and students versus GeoGebra used by teacher only on circle and parallelogram of grade IX, and the second objective to explore the student‟s perception about GeoGebra at grade IX. This research was based on constructivist view of learning. A pre-test and post-test of quasi-experimental research design was used to find the effectiveness of GeoGebra on students‟ achievement. Researcher used conventional sampling and selected two schools from the Baglung district. For the research purpose, I selected 20 students from New Life Secondary Boarding School as experimental group and 18 students from Golden Future Secondary Boarding School as control group. For the data collection, I used mathematical achievement test, a set of questionnaire related to five point Likert‟s scales and semi-structure interview. The mathematics achievement test was used to fulfill the first objective and the set of questionnaire and semi- structure interview were used for second objective. The results indicated that there was a significant difference between the average achievements of students taught by using GeoGebra by both teacher and students versus GeoGebra used by teacher only. The finding illustrated that the students in the experimental group performed better than the control group. Additionally, a set of questionnaire related to five point Likert's scale and interview were used on both experimental and control groups to explore the student's view about GeoGebra at grade IX. The result of questionnaire and interview showed that, students had positive perception about GeoGebra software in teaching geometry.
