Developing of Problem-Based Learning Devices to Teach Numbers Pattern Materials

摘要

The purpose of this research is to produce a Mathematical Learning Devices Model Problem based learning to Teach Numbers Pattern Material, which fulfills valid, practical, and effective criteria. This research method is categorized as development research. The sample in this study was an eighth grade students of Junior High Scholl state 3 Tondano. In this research the lesson plan (RPP), student worksheet (LKPD), and learning outcome evaluation (EHB) were developed using the problem based learning model. The results of this study show that the products developed met valid, practical, and effective criteria. Learning devices are feasible to use based on the evaluation of learning devices by the validator with an average score of 3.9 categorized as valid. The practicality results of the learning kit were obtained from the student response questionnaire which showed that the developed device met the practical criteria to be used as learning source. The effectiveness evaluation indicates that the use of the developed device improves students' mastery learning Students above the average score, suggesting that the learning device is effectively used in teaching mathematics.
