The Development of Materials Based on Metacognitive Approach to Improve Mathematical Reasoning Ability and Emotional Intelligence Students of SMP Sabilina Tembung

Abstract

There were three objectives of this research, namely; (1) to describe the validity, praticallity and effectiveness of  metacognitive approach-based materials to improve students’ math reasoning skill and emotional intelligence, (2) to improve students’ math reasoning skill through developing materials, (3) to improve students’ emotional intelligence through developing materials. In order to achieve the objectives of the research, this developing research used the modification of 4-D development model. There were four stages perfomed, namely; define, design, develop, amd disseminate. The experiment was conducted in grade VIII-7 and VIII-8 containing 37 students of Private Junior High School SMP Sibilina Tembung. After experiment I and II, this research found that (1) the validity of material was valid based on the experts, the praticallity of materials met the standards in which the validator stated that the materials can be used by doing some revision, the result of the observation also showed that the material was high category level, the material had proper worksheet, and the effectiveness of materilas could be showed from three sides; the number of students’ completeness, the active participation of students, and the positive feedback of students, (2) there was the significant improvement of students’ math reasoning skill in which experiment II  with 73,03 was higher than experiment I with 69,03, and (3)  there was the significant improvement of students’ emotional intelligence in which experiment II with 2,89 was higher than experiment I with 2,82.
