RESUMO

This research sought to understand how among issues of ENEM, graphs in the context of global warming and climate change, regardless of the focus in discussion, contribute to the significance of the issues and even for the same context, and what are the basic characteristics of the reader of the graphs that questions presume. To this end, a clip was made that made it possible to work with issues of evidence used in ENEM exams published between the years 1998 to 2008, which contained charts and dealt with some aspect of these topics. Based on a discursive perspective from works of M. Pêcheux and E. Orlandi, this research suggests the establishment of criteria for discursive analysis of the issues in order to understand how the ENEM could be intervening in the constitution of the reader of science with regard to this kind of textual materiality. These analyses showed that the questions work in the sense that the Earth was going through a warming caused by anthropogenic emissions of the greenhouse gas CO2. The way this idea is being conveyed, it reinforces a concept of environmental change as a result of a single factor, a simple cause and effect relationship, leaving aside the conception of Earth as an integrated system. The type of reader presumed in science questions proved at odds with the initial proposals of ENEM itself, which point to a critical and reasoning mind, capable of making decisions based on scientific information. For each question investigated a corpus was built with texts that dialogue with each other on the context presented. Scientific concepts that underlie the issues discussed were studied, both from the standpoint of content as well as the methodological point of view, so that it was possible to assess technical aspects of the issues raised, considering that these aspects are significant for readers. Special attention was paid to the study of geoscience content and concepts about the behavior of the Earth, especially on the aspect of climate and its changes over geologic time. The conditions of production for each question were investigated, which required historical research, including analysis of documentary archives that spell out the socio-cultural era in which the issues were produced, among other things
