Abstract

The purpose of this research are to describe: 1) the validity of developing learning materials oriented in the model of Problem Based Learning (PBL), 2) practicality of developing learning materials oriented in the model of problem based learning, 3) effectiveness of developing learning materials oriented in the model of problem-based learning, 4) the increase of studentsí mathematical reasoning ability with the use of the developing learning materials oriented in the model of problem-based learning, and 5) the increase of studentsí self-efficacy using questionnaire. This research is a research and development, the resulted products are teachersí book, studentsí book, studentsí worksheet (LKS), test of mathematical reasoning ability (TKPM), and studentsí self-efficacy. The development of learning materials oriented in the model of problem based learning (PBL) using Dick and Carey development model. The subject in this research are the students of grade X Mia 3 and grade X Mia 4 of SMA Negeri 1 Medan. From the result of Test I and test II obtained: 1) the developing learning materials fulfill the validity criteria, both in content and construct validity, 2) the developing learning material fulfill the practicality criteria, reviewed from: a) validator assessment and b) implementation of the learning materials, 3) the developing learning material fulfill the effectiveness criteria, reviewed from: a) mastery of learning b) studentsí activity, and c) studentsí positive responses. 4) there is an increase in studentsí mathematical reasoning ability using the developing learning materials and 5) there is an increase in studentsí self efficacy that was tested using questionnaire.
