摘要

Mathematical reasoning is one of high-level thinking ability that can be developed through mathematics learning. The student with mathematical reasoning ability can develop their concept in mathematics to solve any problems. Problem with Higher Order Thinking Skills (HOTS) is one of kind problem that needs mathematical reasoning ability that contain of three highest cognitive aspects in revised Taxonomy Bloom. They are analyzing, evaluating, and creating. The research aim is to describe students' mathematical reasoning ability in solving HOTS problems of geometry. This study is descriptive qualitative. The research subjects were 6 students in 8th grade of Junior High School in Surakarta. The data was collected by a test and followed by an interview. The test instrument was based on the indicator of HOTS problem and then was analyzed by the indicator of mathematical reasoning to know the process of their reasoning in solving the problem. The results show that among 6 students, the average percentage of students who can make conjectures is 90%, 88% of students can use the correlation of quadrilateral characteristics, 65% can create valid arguments with systematic steps, and 59% are able to make conclusion. It indicates that mathematical reasoning ability of students in solving HOTS problem is on the medium level.
