This research study is research and development learning devices. The purpose of this study were: 1) Developed problem-based on learning tools with criteria are valid, practical, and effective; 2) Described the improvement of mathematical problem solving skills of student using learning device based on problem based learning developed. Learning device development using 4-D model which developed by Thiagarajan, Semmel and Semmel, was done in two stages: 1) the development of learning devices; and 2) testing devices. The subject in this study were students of class X SMAN 1 Pematangsiantar, while the objects is the PBL developed, mathematical problem solving skill students. The results were obtained: 1) The learning devices based on PBL that developed have valid criteria, practical and effective; 2) There is an increased ability of mathematical problem solving skill of student using learning device based PBL developed.
