This study analyses the view of students' mental models in solving mathematical problems. The study employed a literature review using well-accepted and robust guidelines. Data were collected by searching books and articles of journals. Data analysis techniques were done qualitatively. The finding of this study showed that the mental model is dynamic and can describe the students' level of understanding concepts. The students' mental model of a concept can be known through the search of a consistent problem-solving process because the mental model is an internal representation involving the recall and processing of memory-owned information that aims at solving the problem. Educators must be able to know the student's mental model for learning to be more optimal.
