Ability is superior in this 21st-century learning, it is important to have especially by prospective mathematics teacher students, but there are still many students who experience obstacles in honing these abilities. This study aims to analyze the epistemological constraints faced by students in improving mathematical critical thinking skills in lectures on transformation geometry. This study is descriptive qualitative research; data were collected from the test, interview, and observation. Given five problems related to thinking critically mathematically ability with five indicators, against 6 respondents who have different belief of mathematical, namely high, medium, and low. The results showed that of the five indicators of mathematical critical thinking ability, the lowest was about advice clarification and inference that is giving a further explanation about the application of concepts and ways to deduce problems. Therefore, it is suggested that lectures on transformation geometry are more related to daily conditions and better train students in making appropriate</p> ER -
