Ethno-educational establishments are present in the Wayuu ethnic territories, in which the conceptions of those who inhabit that physical or spiritual vital space must prevail to outline an interaction of cultural and intercultural competence. Ashajawaa: is an intergenerational dialogue strategy that allows Wayuu boys and girls to promote participation through the ability to listen to the stories of wise men and alaülayuu (elders), as well as observation in the contexts of coexistence of the territories. This systematization of experience was carried out with the wise men, alaülayuu and parents of families of the infants of the Mapuain Rural Comprehensive Ethnoeducational Institution, whose purpose is to establish the ashajawaa as interaction strategies for the intergenerational dialogue of the Wayuu boys and girls in the ancestral territories of Mapuain of the Municipality of Uribia. Theoretically it is based on the Wayuu regulatory system where the set of principles, procedures and rites that regulate or direct the social and spiritual conduct of the Wayuu People are defined. It is approached through the Systematization of Experience methodology proposed by Jara (1998), it proposes how that critical interpretation of one or several experiences based on its ordering and reconstruction, explains the logic of the process experienced, the factors that have intervened in said process, how they have related to each other, and why they have done it that way. It is concluded that ashajawaa is one of the fundamental strategies to weave interculturality from dialogic interaction to guarantee the sustainability of the cultural and territorial survival of the e'irukuu of Wayuu children in ethno-educational establishments.
