Abstract :
This study aims to look at the effect of the use of the Two Stay Two Stray cooperative learning model on the mathematical communication skills of class X Madrasah Aliyah Madinatun Najah Rengat students in the 2019/2020 school year. The form of research conducted was quasi-experimental research (Quasi Experiment) with nonequivalent control group design. The population in this study were all students of class X Mipa. X Mipa 1 as an experimental class uses the Two Stay Two Stray cooperative learning model and X Mipa 2 as a control class uses a conventional learning model. The sampling technique uses saturated sampling. Data collection took place from January 14, 2020 to February 4, 2020. Data collection techniques in this study were carried out using test techniques. Data were analyzed using descriptive and inferential analysis. From the results of the study obtained that 4 and, so. This means rejected so it can be concluded that there is an influence of the Two Stay Two Stray type of cooperative learning model on the mathematical communication skills of class X Madrasah Aliyah Madinatun Najah Rengat students.
