Strategi Abduktif-Deduktif Pada Pembelajaran Matematika Dalam Peningkatan Disposisi Siswa

Learning with abductive-deductive strategy is the type of a new approach  learning of mathematical thought processes. The purpose of this research is  to improve students’ mathematical disposition using abductive-deductive strategy. Research carried out a nonrandomized control group, prescalepostscale design in eleventh class in one high school in Pati regency,  Central Java. Data analysis was conducted quantitative-qualitative  research by category early mathematical ability (KAM) and overall. In  addition, purpose of research is to also analyze the interaction between  learning and KAM. The results showed that the increase of students  who got a mathematical disposition learning with abductive-deductive  strategy have same result with the students who got expository. In more  detail, the category of upper class and middle class is showing the same  increase. While the below categories has an increased disposition smaller  than the expository. Interaction between learning and KAM to increase  the disposition showed no signifiant relationship. This research expected  teachers to notice early mathematical ability of students in mathematics and give special attention related to increase in students’ mathematical  disposition, due to certain student groups despite a suitable learning to  improve students’ mathematical ability and disposition, however different the early mathematical ability showed different results Keywords: Strategi Abduktif-Deduktif, Peningkatan, Disposisi  Matematis.
