This research presents a multifaceted analysis for the classification of visual representations present in chemical questions of entrance examinations of five biggest São Paulo public universities: USP, UNICAMP, UFSCAR, UNESP and UNIFESP from 2007 to 2011. Entrance examinations of UFSCAR and UNIFESP used the exam ENEM from 2009 as a selection process, so the test was analyzed too. 252 questions were found with visual representations in general knowledge and specific knowledge test. Some examples of these representations include graphics, flow charts, diagrams, tables, and chemical equations. The visual representations were analyzed for their relation with the text, its functionality, chemical content involved in the question and the required cognitive skills. The results indicate, generally, that the most frequent visual representations are the chemical equations and the two-dimensional representations of molecular structure with content predominance of organic chemistry and physicochemical. About the relation of text-image, there is a high occurrence of cases in which text and image integration is necessary for the resolution of the matter. Regarding the functionality of visual representations, it is noted that: i the test involve in his questions, illustrations that requires chemical knowledge for their interpretations; ii there is predominance of less realistic and more interpretive images; iii the high occurrence of nominative verbal labels. The emphasis on memorization questions containing visual representations was also investigated adopting the Zoller (1993, 1997, 1999, 2001) reference to classify the questions about the cognitive skills required: high or low order. The results indicate that questions that require lower order cognitive skills are prevalent in the tests of general knowledge, and questions that require higher order cognitive skills of specific evidence.
