The production of textbooks also represents an important part of the Brazilian publishing market. In the history of Brazilian education, several policies have been implemented to regulate publication and dis- tribution of books. Since the year 1985, the evaluation, purchase and distribution of textbooks for public schools has been carried out by the Brazilian Textbook Program (Programa Nacional do Livro Didático – PNLD). 1 Throughout the years, Education for Citizenship and an awareness of aspects related to the Nature of Science (NoS) have become important educational goals, which materialize in evaluation criteria for textbooks. In this paper, we seek to understand the ways through which text- books policy texts address and relate these two goals. In order to do that, we con- ducted a discursive analysis in the 2008 edition of the Brazilian Textbook Guide, the frst textbook policy document to explicitly mention NoS. Using Critical Discourse Analysis as our main theoretical and methodological framework, we analyse both conjunctural and textual dimensions of the 2008 Brazilian Textbook Guide so as to problematize both philosophical and educational bases of articulations between NoS and Education for Citizenship. The text is organized in three parts: frst we present a brief summary of NoS related discourses present in the literature and explore possible relationships between NoS and Education for Citizenship.
