Problem solving is the focus and goal of learning mathematics. Problem solving can be developed in many ways, one of which is by using worksheets that contain heuristic problem solving procedures. Currently, the development of technology and the use of digital devices in education is very massive. However, this should not isolate students from interacting and discussing during math learning. The role of the teacher is indispensable in choosing a learning model, therefore this research will focus on the use of digital worksheets in learning mathematics education. The purpose of this study is to determine whether there is a difference in the mathematical problem solving ability of students in the experimental class who learn with a problem-based learning model with control class students who learn by using a conventional model. This research is a quantitative research with quasi experimental design. The results showed that there was a difference in the mathematical problem solving ability of students in the experimental class with the control class.
