In the history of public politics and their impact on the curriculum we propose to show the curriculum’s dominant tendencies but also of the groups and research centers, the most representative authors and their products; And, at the same time, the knowledge-power conecction in the historical process. That process that goes from 1911 to 1998, who was influenced fundamentally by 2 macro curricular models: 1. The Positivism, The New School and the influence of John Dewey (1911-1958); 2. The Social efficiency, The Educational Technology and the constructionist cognitivism (1970-1998); They do not necessarily occur in an alternative way, sometimes they crisscross, or show in a concomitantive form and manage to pass almost unnoticed in “obscure eclecticisms”.
