Developing of Mathematical Learning Devices Based on the Local Wisdom of the Bolaang Mongondow for Elementary School

Abstract

This study aims to develop valid, practical and effective mathematics learning tools based on local wisdom of Bolaang Mongondow using PMRI approach. The method used is the development research method which includes the stages of analysis, design and evaluation. Data collection techniques in the form of documentation, walk through, tests, observations, and interviews. Data analysis techniques used qualitative descriptive data analysis. The results obtained are in the form of a valid and practical learning device prototype. Validity is fulfilled qualitatively. Whereas, the practicality shown by experts stated that the developed prototype could be applied to elementary students. Apart from that according to the one to one and small group stages, students can use learning tools well. From observations of student learning activities, the results of student answers, it can be seen that the prototype developed has a potential effect to improve students' mathematical abilities.
