Abstract

One of students’ abilities which can facilitate them to understand geometric concepts is spatial reasoning ability. Spatial reasoning ability can be defined as an ability involving someone’s cognitive processing to present and manipulate spatial figures, relationship, and figure formations. This research aims to find out significant difference on students’ spatial reasoning ability between students who are given Model Eliciting Activities with Cabri 3D (MEAC) and those who are only given Model Eliciting Activities (MEA). Quasi experimental design is used in this research which involves 143 junior high school students as the sample. The result of this research shows that students who are given Model Eliciting Activities with Cabri 3D have better spatial reasoning ability than those who are given Model Eliciting Activities. It is suggested for Matematics teachers to implement instruction with Model Eliciting Activities with Cabri 3D
