La realidad étnica es visto analizado y cuestionado como un problema de construcción del conocimiento del sí mismo y su aprobación de sujetos étnicos en la educación superior. Con este propósito examina la política educativa desde 1930 hasta la fecha. Como resultado de las diferencias entre la castellanización-aculturación-integración versus refuerzo lingüístico y articulación cultural. Ethnic reality is seen, analyzed and questioned as a problem ofconstructing the knowledge of "itself" and its apropiation up didactic o "ethnic subjects" brought up in high education. Withthis purpoue we examine political education from 1930 up to now. As a result differences between castilianisation-acculturation-integration vs. linguistic-reinforcement a¡d cultural articulations appear, finding coincidences in the historical context. In the last one, ethnic facts are homogenized as unique and they are also submited to the nation. This problem and the existence of two logical historical-scientific thoughts of the western society and ethnic groups that respond to cultural realities, and differencesin language, are proposed to be considered in the field ofprofesional training for ethnic groups.
