It aims to reveal the phenomena that occur in the field through a descriptive research design that uses written and oral conversations between the author and informants. Based on the results of interviews conducted by the researcher, it was found that differentiated learning using the Problem Based Learning model, especially in PPKn subjects in class VII, made students happier and more interested because the role of the teacher, especially in PPKn subjects, made students enthusiastic in learning because the role of the teacher as a motivator greatly influenced the teaching and learning process.
