## Abstract

This study to: (1) To analyze the effect of KAM on mathematical communication skills and students independence between the PBL and STAD models with the help of geogebra- (2) To analyze the difference between the improvement of mathematical communication skills and student independence between PBL and STAD models assisted by geogebra (3) to analyze the interaction between learning models and early mathematical abilities on students^ mathematical communication skills and independence. This research is categorized into the type of quasi-experimental research (quasi-experimental). The population of this study were all students of class VIII SMP Muhammadiyah 16 Lubuk Pakam and the samples were class VIII-1 (Experiment 1) and VIII-2 (Experiment 2). The results of the study are: (1) obtained Fcount is greater than Ftable (79.968 > 4.042) and with a probability value (sig) of learning factor of 0.000 so that there is an effect of KAM on students mathematical communication and Ftable (21.007 > 4.042) and with a probability value (sig) of learning factor of 0.000 so that there is an effect of KAM on independence- (2) Fcount is greater than Ftable (43.451 > 4.042) and with a probability value (sig) of 0.000 so that there is a difference in the increase in mathematical communication skills
