Abstract
The purposes of this study were: 1) Developed problem-based on learning tools who meet the criteria are valid, pratical, and effective; 2) Described the improvement of mathematical problem solving skills of student using learning device based on problem based learning developed . Research development of 4-D model 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.
