Daftar Isi:
- The purpos study are to produce mathematical learning tools that are valid, practical and effective through Problem-Based Learning (PBL) model to improve mathematical communication skills of VII grade students of Jabal Noor IT Middle School. Specific objectives in this study are to: 1) produce mathematical learning devices that are valid, practical and effective to be used in the teaching and learning process. 2) to improve students' mathematical communication skills using learning tools developed based on the PBL model. This research is a development research developed with a 4-D model, namely defining, designing, developing, disseminating. Learning devices. Learning models developed in this study include the Learning Implementation Plan (RPP), Student Book (BS), Student Activity Sheet (LKPD). In addition, researchers have also developed research instruments that consist of tests of students' mathematical communication learning abilities. After being analyzed using learning tools it can be concluded that there is an increase in students' mathematical communication skills, where the average increase in mathematical communication skills of students from trial I and trial II in the trial I is 0.48 points with an increase in mastery of learning in 23% classics
