Evaluation of effectiveness of an enriched curriculum prepared using Geogebra software

The purpose of this research is evaluation of effectiveness of enriched curriculum prepared using GeoGebra software and covers squares and rectangles subjects. In the study pre-test post-tests control group design was used. Firstly, pre-test was applied for the creation the experimental and control group in the study. Because no significant difference between pre-test scores groups were randomly assigned as experimental and control groups. After selection of the group, experimental material was applied to the experimental groups over two weeks. The control group did not receive any action. Post-test were applied to the experimental and control groups after the experimental application. Obtained post-test results were compared using t-test technique. According to comparison, significant differences between experimental and control groups was found in favour of the experimental group.
