Implementation of Mathematics Learning-Assisted Cabri 3D Software to Improve Spatial Ability of High School Students on Three Dimensional Geometry

Abstract

The purpose of this study to analyze student’s spatial abilities to resolve 3D geometry problems through mathematics learning-assisted using Cabri 3D software. The population in this study were students from one of High School Student in Kuningan, West Java. Selection of sample by purposed random sampling, the experimental class is taught mathematics learning-assisted using Cabri 3D, while the control class is taught by conventional learning. This study was quasi-experimental with pretest and posttest control group design. Data analysis using two way anova by linking between learning model with gender factor and early mathematical abilities (KAM). Based on the results; (1) The enhancement of student’s spatial abilities through Cabri 3D was higher than the conventional learning; (2) based on gender, there were no significant effect of student’s spatial abilities who exposed with Cabri 3D and conventional learning; (3) based on KAM, there was significant effect of student’s spatial abilities among ability of high, middle, and low KAM. The differences occur between high, middle and low KAM. (4) based on the questionnaire results, students ‘responses to the positive Cabri 3D positive model, as much as 73.85% agree that learning Cabri 3D can improve understanding, interest and students’ abilities to learn the concept of 3 dimensional geometry. Based on this result, mathematics learning-assisted Cabri 3D can be applied in the process of mathematics learning in high School.
