Thi s research analyzed mathematical dis course of the students in an RME-based differential equations cour se at a university in order to investigate the social transformation of the students' conceptual model
of differenti al equations. The analysis focused on the change in the students ' use of conceptual metaphor for differential equations
and pedagogical factors promoting the change.
The analysis shows that discrete and quantitative conceptual model was prevalent in the beginning of the semester.
However, continuous and qualitative conceptual model emerged throu gh the negotiation of math ematical meanmg based on the inquiry of
context problems. The participation in the project class has a positive impact on the extension of the students ' conceptual model of different ial equations and increases the fluency of the students ' problem solving in differenti al equation s. Moreover, this paper provides a discussion to identify the pedagogical factor s involved with the transformation of the
students ' conceptual model. The discussion highlights the sociocultural aspect of teaching and learning of mathematics and provides
implications to improve teaching of mathematics in school.
