Development of learning device oriented problem based learning to improve student’s mathematical problem solving skill

Abstract

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.
