This study focuses on discussing the results of the analysis of (1) the value of integrated social studies learning outcomes of students who are taught using the Problem based learning (PBL) model, (2) the value of integrated social studies learning outcomes of students who are taught using conventional learning models, (3) comparison of the results of Integrated Social Studies learning students who are taught using the Problem based learning (PBL) model with the value of Integrated Social Studies learning outcomes students who are taught using conventional learning models. This research method is quantitative with a quasi-experimental design. The population of this study was students of class VIII A and VIII B of SMP Negeri 6 Welak 2020/2021, with a total of 50 students (classes VIII A and VIII B each consisted of 25 students).
