An Analysis of Olympiad Students’ Critical Thinking In Solving National Science Olympiad (Osn) Problem on Number Theory Material

Abstract

This research aimed at describing the process of the mathematical Olympiad students in solving National Science Olympiad (OSN) problem on number theory material. The subjects of the research were 4 Olympiad students at Pythagoras Development Center of Mathematics and Natural Sciences Jember. The data collection methods used were test and interview. In this case, every student had strengths and weaknesses in solving the problem. All of the students were able to write and explain what was known and asked but they were still lack to model the problem into mathematical form. The students were able to formulate properly but were lack to construct it into various possible answers. All of the students were able to write systematic steps and correct conclusion. All of the students checked all the results, but there were still some students who were not careful in checking, so there were inappropriate answers
