The following research analyzes the protective role that has been historically assigned to women. The naturalization of the role of women attributes the care of family life per se, an inherent moral obligation is generated that must be assumed responsibly. This type of knowledge systematized from the human sciences allows us to recognize that in the educational field the female presence predominates, reproducing customs, practices and particular processes of the gender, so obtaining data from secondary sources on female teachers constitutes a point of departure to understand feminization in Normal Schools in Chile. It should not be forgotten that women predominantly occupy roles related to the domestic household, which is consolidated with the ingrained idea that the mother is the first teacher of her children. This ideation is carried over to the school and teachers and mothers are confused in a single role.
