The Use Of Cabri 3D Software As Virtual Manipulation TooludIn 3-Dimension Geometry Learning To Improve Junior High School Students’ Spatial Abilityud

摘要

This study is aimed to know students’ spatial ability who work under 3-dimension learning use Cabri 3D software at Junior High School in Bandung. The using of Cabri 3D software as manipulative tool in 3-dimension geometry learning can reduce misperception about 3-dimension materials. This study is quasi-experiment and the instruments cosist of spatial ability test and students’ worksheet. This study is conducted for 8th grade students at Junior High School in Bandung.udBased on study result, it is found that students’ spatial ability enhancement under the learning, where Cabri 3D software is used, than those who were taught by conventional learning. From five elements of spatial ability based on Meir (1976), only 2 elements of spatial ability which do has no improve merit significantly, namely, perception ability component and visualization ability, while rotation ability, relation ability and orientation ability have improved significantly.ududKey Words: Cabri 3D Software, Virtual Manipulation Tool, Geometry 3 Dimension, Spatial Abilityud
