The research applied seeks to answer the question "How is it being developed and what is the epistemological and pedagogical foundation within the teaching practices of the chair of peace in two educational institutions in the district of Bogota ?, in order to generate from the results found, a pedagogical proposal in regards to the collective memory, as a possible way to approach a field such as the chair of peace. This one was carried out from the educational ethnography as a research methodology and using different tools such as field diary, semi-structured interview, survey and documentary review. In there, the importance of investigative processes as a mean of constant formation (researcher-community) was evidenced, in conclusión, wether there is an interest from the entire educational community to address the issue of conflict and peace, there is a gap between the constitutional decree and its implementation, which first passes through a void of communication between all the levels involved in the regulation and implementation of the field in mention (MEN, teachers, students, etc.), which leads to widespread ignorance in general; so the implementation is developed from processes that precede the same regulation, where relevance is given to the role played by collective memory in the construction of a culture of peace, in addition, it is clear that there must be training spaces and a specific item that allows generating a meaningful chair of peace for the educational community, of transversal and multidisciplinary character, characteristics that are contemplated in the pedagogical proposal that was elaborated.
