How are students' higher order thinking skills (HOTS) in mathematical problem solving viewed from the ability to understand mathematical concepts?

Abstract

The process of learning mathematics requires Higher Order Thinking Skills (HOTS) to solve various mathematical problems. The HOTS of each student is different, one of which is influenced by students' understanding of mathematical concepts. This study aims to determine the students' HOTS in solving mathematical problems on the flat shape material based on the ability to understand students' mathematical concepts. This type of research is qualitative research. Data collection techniques were carried out by test and interview methods. The subjects in this study were three fourth grade students at SD Islam Terpadu Adzkia Indonesia consisting of one student with high concept understanding ability, one student with moderate concept understanding ability, and one student with low concept understanding ability. The data validity technique uses a time triangulation technique. Technical data analysis uses data reduction, data presentation, and conclusions. The results of this study indicate that the HOTS of students with high conceptual understanding abilities have the ability of HOTS indicators in the aspects of (a) analyzing, (b) evaluating, (c) and creating. Students with moderate concept understanding ability have the ability of HOTS indicator in the aspects of (a) analyzing, and (b) evaluating. Students with low concept understanding ability do not have the ability of HOTS indicator.
