Mathematics is closely related with daily life, including religious life. Islam explicitly makes mathematics a scientific discipline that is widely used to solve various problems in lives. The aim of this research is to assist students in achieving learning objectives by problem-based learning models based on Islamic context. This research uses quantitative methodology and the type of research was used pre-experimental design with pre-test and post-test group design. All students at Year 7 from one of junior high schools in Banda Aceh, Indonesia as t population. The research data was collected through tests (pre-test and post-test) using instruments in the form of test question sheets containing questions related to Set. The results of the study concluded that student learning outcomes improved after implementing a problem-based learning model based on an Islamic context. The improvement of student learning outcomes from the average value of 17.69 with 0% completeness before the intervention, which subsequently increased to an average value of 75.4 with 92.3% completeness after the intervention. Learning by problem-based learning models based on Islamic context can be a good alternative learning strategy that can be implemented.
