Abstract

Problem-solving is the essence of mathematics and is the main goal in learning mathematics. Many students did not have good problem-solving skills based on the field observations. The problems grew up because the students were not used to solving the problems and the problem-solving stages. They did not include issues with high complexity, such as questions with the High Order Thinking Skills (HOTS) category. The problem-solving steps have been developed, such as; Dewey (1910), Polya (1945), Mason, Burton & Stacey (1982), Schoenfeld (1985), and Wilson et al. (1993). The objective of this current study was to analyze the stages of problem-solving in solving mathematical problems with the High Order Thinking Skills (HOTS) category. The research sample was 57 students of Mathematics Education in one of Private University of Indonesia who took the Integral Calculus subject. This research was a qualitative descriptive study. The data analysis employed an inductive approach where the conclusions were drawn from minor case investigations to provide comprehensive results. The data analysis consisted of reduction data, presentation data, and concluding. There are three results from the current research. First, the students have not implemented problem-solving with problem-solving stages; second, The students fail to solve the problems due to a lack of mathematical literacy skills; last. The incomplete mathematization process causes imperfect problem-solving. Based on the results, the research recommendation is to add stages of problem-solving with two steps: formulating the situation mathematically and understanding mathematical solutions in real life or problems.
