The used methodology was that of the combined methods, based in Creswell (2010). The quantitative analysis was made in a descriptive way, showing results by charts and tables. The qualitative analysis employed the methodology of Textual Discourse (MORAES; GALIAZZI, 2011).

Thus, the pupils development was not satisfactory, considering Literacia as abilities and competences employment. Third degree pupils had better results than that of the first ones, but with similar difficulties in Treatment Information and Uncertainty. The shown abilities and competences in each degree, associated to those linked to this knowledge phase show the loss of learning in this area on the high school conclusion.
