This research intended to improve students' learning results in solving problems on Subnetting materials by using learning modules. The research method used experiments with True Experimental Design in the form of Post-test Only Control Design. This method uses two randomly selected groups to be a control group and an experimental group. The control group was not given treatment, while the experimental group was given treatment. After giving treatment both groups will be given the posttest to know the learning result from each group. Based on the research findings obtained from the hypothesis test, the average value learning control class is 69.88 and the experimental class is 84.90. So it can be concluded that the result of Subnetting material problem solving by using Project Based Learning module gets higher learning from those not using Project Based Learning module.
