Abstract

Problem solving ability is one of the mathematical ability has an important role in the success of students. But in reality the student's ability to solve the problems of mathematics remains low. For that we need a model of learning characteristics and steps to develop problem-solving abilities, one suitable model is the Problem Based Learning (PBL). Learning in the classroom implementation requires a learning device for its operation, but that happens in the field of devices used have not been tailored to the needs of students and not able to improve students' mathematical problem solving ability. Related to the above description, it is to investigate the device characteristics based math learning Problem Based Learning (PBL). This research is the development of the model of development Plomp, consisting of the preliminary analysis phase, a development phase or loading a prototype,and the assessment phase. In the phase of the preliminary analysis carried out a needs analysis, curriculum analysis, concept analysis, and analysis of the students. In the  phase prototype is to design devices based learning PBL form of lesson plan and student worksheet, then conducted a formative evaluation to determine the validity and practicalities. While the assessment phase assessment of the practicalities and effectiveness. The result showed that the device has a valid learning developed with the average index for the lesson plan and student worksheet validity of 82,25% and 78,85%. Learning device has been practically designed with practicality percentage of teachers' questionnaire responses 90,28%%, 87,5% student response, and enforceability of the observation sheet lesson plan 92,52%. The results show the effectiveness of data analysis designed device has effectively improve students' mathematical problem solving with an average percentage of 79,43% achievement indicators. Based on these results it can be concluded that the device-based math learning Problem Based Learning (PBL), which has been designed valid, practical, and effective improve students' mathematical problem solving ability grade VII junior high school.
