Reconceitualização das categorias de skemp de compreensão relacional e compreensão instrumental como critérios globais

The thesis presents a systematic description about the meaning, as Skemp, relational understanding and understanding instrumental, in the context of mathematics learning, being that we had as a guide his understanding of the schema. Especially, we analyze some academic productions, in the area of Mathematics Education, who used the categories of understanding relational and instrumental understanding how evaluative instrument and we see that in most cases the analysis is punctual. Being so, whereas the inherent understanding relational schema has a network of connected ideas and non-insulated, we investigated if the global analysis, where it is the understanding of the diversity of contributory concepts for formation of the concept to be learned, is more appropriate than the punctual, where does the understanding of concepts so isolated. For this, we apply a teaching module, having as main content the Quaternos Pythagoreans using History of Mathematics and the work of Bahier (1916). With the data we obtained the teaching module to use the global analysis and the punctual analysis, using research methodology the Case Study, and consequently we conduct our inferences about the levels of understanding of the subject which has made it possible for us to investigate the ownership of global analysis at the expense of punctual analysis. On the opportunity, we prove the thesis that we espouse in the course of the study and, in addition, we highlight as a contribution of our research evidence of need for a teaching of mathematics that entices the relational understanding and that evaluation should be global, being necessary to consider the notion of schema and therefore know the schematic diagram of the concept that will be evaluated

A vigilância na internet: a circulação midiática brasileira do vazamento de dados da NSA por Edward Snowden

This research seeks to understand how the problem of information security is treated in Brazil by the public thematization and also how it can affect the political and economic aspects of both Brazilian companies and government by using a study case based on the document leak event of the National Security Agency by Snowden. For this, the study case of sites, blogs and news portal coverage was carried out from the perspective of evidential paradigm, studies of movement and event concept. We are interested in examining how the media handles the information security topic and what its impact on national and international political relations. The subject matter was considered the largest data leakage in history of the NSA, which ranks as the world's largest agency of expression intelligence. This leak caused great repercussions in Brazil since it was revealed that the country was the most watched by the United States of America, behind only USA itself. The consequences were: a big tension between Brazil and the US and a public discussion about privacy and freedom on Internet. The research analyzed 256 publications released by Brazilian media outlets in digital media, in the period between June and July 2013.
