Abstract
Abstract Reasoning skill is essential for students to have to face the challenges of the 21st century. This study aims to determine the percentage of students' reasoning skills based on deductive hypothesis, inductive hypothesis, and reflective abstraction. This research used a descriptive method involving 26 students of Islamic Senior High School 4 Bantul. The data from tests were analyzed quantitatively, while the data from interviews were analyzed qualitatively as supporting data. The results showed that the indicators of deductive hypothesis: Aspects of explaining a fact, there are 62% of students explained the facts correctly but were incomplete and 38% of students explained the facts incorrectly; Aspects of making conclusions deductively, there are 77% of students made correct conclusions but were incomplete and 23% of students made incorrect conclusions. Based on inductive hypothesis indicators: Aspects of making conclusions inductively, all students can make conclusions, but incorrect in associating equations; Aspects of giving reasons, all students gave incorrect reasons. Based on indicators of reflective abstraction: Aspects of developing concepts, there are 50% of students who can connect concepts in a case correctly and 50% of students incorrectly connect concepts in a case. This showed that students' reasoning skill is still low. Abstrak Kemampuan penalaran penting dimiliki oleh siswa untuk menghadapi tantangan abad 21.
