Mathematical reasoning ability of junior high school viewed from logical mathematical intelligence

Abstract

Mathematical reasoning is crucial especially at school since students need to think logically and be able to draw new conclusion based on evidence. This is a descriptive qualitative research which aims to analyze mathematical reasoning ability viewed from logical mathematical intelligence with 32 eight graders of Junior High School of 01 Jiwan involved. Instrument used is mathematical reasoning ability and logical mathematical intelligence test. The result of the research shows that students with high logical mathematical intelligence were able to present mathematical statement (88.89%), compile evidences or create solution (81.48%), design the characteristic or relationship pattern of mathematical phenomena (74.07%), and describe the logical conclusion related to ideas and their relationship (77.78%). Students with medium logical mathematical intelligence were able to present mathematical statement (60%), compile evidences or create solution (71.11%), design the characteristics or relationship pattern of mathematical phenomena (55.56%), and describe the logical conclusion related to some ideas and their relationship (57.78%). Students with low logical mathematical intelligence were able to present mathematical statement (58.33%), compile evidences or create solution (54.17%), design the characteristics or relationship pattern of mathematical phenomena (50%), and describe the logical conclusion related to some ideas and their relationship (45.83%).
