This work has the main purpose of conducting a survey of educational products present in dissertations and doctoral theses focused on the use of history in mathematics teaching and Didactics of mathematics with a French foundation produced in graduate programs in the strict sense of the Brazil between 1990 and 2010, the areas of Education, Mathematics Education, school of Natural Sciences and Mathematics and related areas, according to the research proposal of Mendes (2010). Our interest was to select the products that present concrete proposals for educational activities that can be used in the classroom of Basic Education and Training of Teachers of Mathematics. The research was implemented through a bibliographic study documents the Bank of dissertations and theses from CAPES, libraries and archives of some Postgraduate programs in the country who focus their studies on the subject object of this research, besides the Brazilian Digital Library Theses and Dissertations (BDBTD). From this survey we selected works that present educational products materialized in blocks of activities based on the use of teaching history of mathematics to the classroom as well as the sequence of activities based on the Teaching of Mathematics. In possession of material, produce a CD-ROM containing the selected activities, in order to help support the work of teachers regarding the use of these activities, as a supplementary material to textbooks in their math classes

Conversações políticas no youtube: junho de 2013 e circulação de sentidos nos comentários do vídeo “globo e os protestos”

This re search analyzes the talks dynamics about policy established in YouTube symbolic space. We are interested in examining the way in which the commentators of the video " Globo e os Protestos " articulated in the field intended for comments, a public space directed to the dissemination and circulation of meanings about policy issues. The video studied was published by PC Siqueira and Diego Quint eiro , during the June 2013 protests in Br azil, to direct the political understanding of the movement lived in that period. According to them, the protests had left political position and therefore the protesters should reject the coverage by TV Globo (a comunication vehicle with ideals of right) and allow the participation of political parties linked to the ideological left spectrum. This narrative generated empathy and controversy betwe en commentators, which produced in the comments, an intense argumentative process about these theses (right and left). To understand the phenomenon, we conducted an exploratory qualitative research, the main methodological procedure was a ethnomethodological discourse analysis. We seek the observation of the ways in which the commentators es tablished talks about politics in the comments space, for, thereafter , organize categories of analysis based on identified discursive recurrences. The empirical reflections are supported from discussions about the YouTube potential, while digital media com prising massive strategies and while articulating space in the engagement of individuals in political issues; also confront the aspects involved in the conversation practices that results in sociability dynamics and , especially , in conflict, on the socio - t echnical networks; and finally, we propose a reflection about the circuit actuation in which the people take ownership and realize new readings about the products received. Concluding that the use of digital media , such as YouTube, has caused significant c hanges in the forms of production and reception of symbolic products and ways in which people participate in political issues concerning life in society.
