Abstract
This research is qualitative research that purpose to describe critical thinking stages of college students for each level of critical thinking skills in Mathematics Education Study Program FMIPA UNNES for solving mathematics problems. In the clarification, a subject in critical thinking level 0 until level 3 showed the same characteristic that is getting the information in the picture, and be able to create images to get additional information. In the assessment, subjects in critical thinking level 0 just dig a small portion of relevant information, the subject in critical thinking level 1 until level 3 dig most of the information. In the inference stage, a subject in critical thinking level 0 to level 2 only using inductive thinking, subject in critical thinking level 3 using deductive thinking. In the strategy stage, a subject in critical thinking 0 using the analogy or not can come up with strategies employed, subject in critical thinking level 1 and level 2 using the analogy, subject level 3 using his own ideas by looking for relationships in solving problems.
Keywords: critical thinking, the stages of critical thinking, clarification, assessment, inference, strategies , and solving mathematics problem
