Analysis of High Order Thinking Skill (HOTS) in Problem Solving Reviewed from the Mathematical Reasoning of Students of SMA Negeri 5 Medan

The issue of pupils' poor reasoning and high-level thinking skills is the driving force for this study. Thus, the purpose of this study is to characterize students' high-level thinking and reasoning skills, as well as the challenges they face while attempting to solve HOTS issues and the important relationship between their reasoning skills and their higher-level thinking skills. This study examines the causal relationship between students' challenges in completing HOTS and their reasoning and higher order thinking skills. The impact of reasoning skills on advanced thinking skills should therefore be examined inferentially. Students in Class X of SMA Negeri 5 Medan served as the research subjects. There were thirty-five individuals in this study. Six kids who fell into the very low, low, medium, high, and very high categories of thinking ability were the interview subjects. Reasoning ability tests and HOTS, which were taken straight from the PISA problem collection, were utilized to gather data on high-level thinking and reasoning skills. To learn more about the challenges students face when tackling HOTS tasks, researchers conducted in-person interviews. According to the study's findings, students' reasoning skills fall into the low group with an average score of 58.88, and their high-level thinking skills fall into the same area with an average score of 60.85.
