The research was conducted at a university in Northwestern Colombia. This paper presents a section of the results of a larger project whose objective is to identify the elements that aid participants in building and elaborating arguments in culturally infused discussions. Socratic questioning was an integral element of the discussions. To attain the purpose of this study, a qualitative single-case design was employed.
