This work is the result of research that sought to analyze changes in teaching knowledge following the implementation of the Curriculum Proposal of the Municipal Department of Education of Irati/PR. It is organized into three chapters: Chapter I, "Public Education Policy: the Curriculum Proposal of the Municipal Department of Education of Irati/PR," discusses key concepts such as politics, public policy, social policy, and educational policy; state interference in policies; the curriculum as an intersection of practices; the recontextualization of Basil Bernstein's pedagogical discourse; and presents the Curriculum Proposal of the Municipal Department of Education of Irati/PR. Chapter II, entitled "Teaching Knowledge: From Continuing Education to Pedagogical Practice," involves debates on continuing education for teachers, teaching knowledge, and pedagogical practice. Chapter III, entitled "Voices Reached: teachers' discourses on changes in knowledge based on the Curriculum Proposal of the Municipal Secretary of Education of Irati/PR," argues that teaching knowledge is altered with the implementation of the Curriculum Policy and that change happens slowly in continuing education courses.
