<![CDATA[The aim of this research is to determine the influence of the Creative Problem Solving Learning Model on student’s Mathematic Communication Skills of UPTD SMPN 3 AIR BATU. This type of research is quasi experimental with a Two Group Pretest-Posttest Desain research design. The population in this study are all VIIth class that consist of 2 classes. The sample in this research are VIIth-2 Class as an experimental class using the Creative Problem Solving Learning Model assisted by the Geogebra application and VIIth-1 Class as a control class using an Expository Learning Model taken by total sampling. Before the learning, a pretest is obtained as an average result of the experimental class of 18,89 and a control class 21,78. While after the learning, a posttest is obtained with an average result of the experimental class 88 and the control class 51,8. The result of the t test obtained t count>t table (15,452>2,010) thus H  was accepted, the conclusion there is an influence of the Creative Problem Solving Learning Model assisted by the Geogebra application on student’s Mathematical Communication skills of UPTD SMPN 3 AIR BATU on flat-sided geometric materials (cubes and beam) 2023/2024 academic year.Keywords: Creative Problem Solving, Geogebra, Mathematical Communication]]>
