"Nova Função Social para a Universidade do Século XXI" is a comprehensive guide that examines the impact of the reform pact proposed by UNESCO on university pedagogy for teacher education. The book addresses the central question of the new social function of the university in the 21st century and its influence on teacher training. It adopts a dialectical approach based on theoretical and methodological concepts of reproduction and contradiction. The analysis is conducted through the lens of the technical, scientific-pedagogical, and socio-political dimensions of teacher education. The author, Paulo Fioravante Giareta, highlights how UNESCO's reformism adapts and legitimizes the social function of university pedagogy to meet the demands of the new productive order.
