Deskripsi: This study aims to investigate conceptual understanding based on the cognitive process and to describe the learning obstacles faced by students to digest the notion of definition of a function. For this purpose, a case study is conducted by involving three undergraduate students of mathematics education program as the subjects. One is a second semester student (M1), and the other two are a sixth semester student (M2) and eighth semester student (M3), respectively. The data are collected using observation, tests, and interviews. We found that M1's process level of cognitive is in remembering. M1 experienced didactical, cognitive, and epistemological obstacles; M2's process level of cognition is in remembering and understanding, which reveals cognitive and epistemological obstacles; M3's process level of cognition is in remembering, which shows cognitive and epistemological obstacles. The results are definitely important to improve the process of teaching and learning at universities.
