Abstract
Mathematical communication is one of the important abilities for students to face the challenges in this era. The fact-based on the preliminary study conducted by researchers on students in elementary school showed that most students find difficulties in communicating mathematical ideas. The present study is aimed to describe whether the improvement of mathematical communication ability of students who learn through project-based learning using mind map technique is better than the improvement of mathematical communication ability of students who learn through project-based learning without mind map technique. This study used a quasi-experiment using a non-equivalent group design. Sixty-three students of one of the elementary schools in Bandung city were taken as subjects of this study. The instrument of this study used mathematical communication test. The data were analyzed using non-parametric statistics. The result showed that the improvement of mathematical communication ability of students who learn through project-based learning using mind map technique is better than the improvement of mathematical communication ability of students who learn through project-based learning without mind map technique.
