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 problembased learning, 4) the increase of students’ mathematical reasoning ability with the use of the developing learning materials oriented in the model of problembased learning, and 5) the increase of students’ selfefficacy using questionnaire. This research is a research and development, the resulted products are teachers’ book, students’ book, students’ worksheet (LKS), test of mathematical reasoning ability (TKPM), and students’ selfefficacy. 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) students’ activity, and c) students’ positive responses. 4) there is an increase in students’ mathematical reasoning ability using the developing learning materials and 5) there is an increase in students’ self efficacy that was tested using questionnaire.
