This study aims to improve the mathematics learning outcomes of class VIII.A students at SMP Negeri 225 Jakarta, totaling 40 students, through the application of the Google Classroom application. The research was carried out in the odd semester of the 2021-2022 Academic Year, precisely from September to December 2021. The research method used was classroom action research which was designed in two cycles. Each cycle is carried out in four stages, namely planning, implementation, evaluation and reflection. The results of the study obtained data on student learning outcomes in the Pre-Cycle, the average value of students was only 63.25. Students who achieve completeness are students who get a score equal to or above the KKM (KKM = 75) as many as 10 students (25.00%). In Cycle I, the average value of students is 72.00. There were 25 students (62.50%) who achieved completeness. In Cycle II, students who achieved completeness were 31 students (77.50%). The results of this study indicate that there is an increase in mathematics learning outcomes by 15%. The conclusion of this study is that learning through the application of the Google Classroom application can improve mathematics learning outcomes for class VIII.A students at SMP Negeri 225 Jakarta.
