RESUMO

he present research explored the relations between the performance in ENADE 2005, the performance in EGRAF and the deductive reasoning of 141 Freshman and Senior students of the Computer Science course when involved in tasks that explored the mathematic thinking. The instruments were the ENADE exam, the EGRAF exam and the psychological test GfRLD. In addition, twelve of those students were submitted to an individual test of some mathematical ability components and the mental representation, over there the variables studied for the 141 students. For the ability and the representation five of Krutetskii s serie XIX- B series problems and a semi structurated interview were used. During the application of the Krutetskii s test, the twelve students were invited to think out loud. Notes were made to complement information not captured by the voice and image videotape. The main results showed that nine out of twelve students were considered more skilful and presented a tendency to represent the problems in a propositional way. This representation when used by students that dominated the elements of the problem and its relations took them to success in their solutions. Those students performances in ENADE indicated no association with the fact that they were Freshmen or Senior students, but they were related with the level academic performance. The deductive reasoning differed significantly between Freshmen and Senior students and, between well and bad succeeded in academic tasks. In general, the 141 students tended to present association between ENADE performance and EGRAF performance, that evaluate the fluid-crystallized and crystallized intelligences, respectively
