Abstract:
Assessment is a crucial aspect of education. A critical point in the evaluation is the validity of the instruments used in conducting the assessment. However, some studies do not pay more attention to this section, which results in the invalid results of the resulting research. This study aimed to map the indicators of the Higher-Order Thinking Skills (HOTS) of mathematics students and analyze their existence as components of the instruments. The subjects were 203 senior high school students of science, Manokwari, Indonesia. Test instruments that involved five critical and four creative thinking were used to measure students' HOTS. The data was analyzed using multidimensional scaling (MDS) to map the indicators. The results showed that the five indicators of critical thinking skills form a unified distribution pattern, while the four indicators of creativity tend to spread. Therefore, each indicator used has a unique contribution in explaining the HOTS of mathematics students.
