Development of Learning Devices through Problem Based Learning Model Based on the Context of Aceh Cultural to Improve Mathematical Communication Skills and Social Skills of SMPN 1 Muara Batu Students

Abstract

The purposes of this study were:1) Developed problem-based on learning tools in the cultural context of Aceh (PBM-BKBA) who meet the criteria are valid, practical and effective; 2) Described the improvement of communication capabilities mathematics and social skills of students using the PBM-BKBAdeveloped; and 3) Described the process of student answers in solving mathematical communication skills.Research development of 4-D model was done in two stages: 1) the development of learning devices; and 2) testing devices. The subjects in this study were students of class VIII SMPN 1 Muara Batu, while the object is the PBM-BKBA developed, mathematical communication skills, and social skills of students. The results were obtained: 1) The PBM-BKBA that developed have valid criteria, practical and effective; 2) There is an increased ability of mathematical communication and social skills of students using the PBM-BKBA developed; 3) the student answers on trial II trial better than I.
