O que a inteligência prediz: diferenças individuais ou diferenças no desenvolvimento acadêmico?

The psychometrics has emphasized the role of intelligence in explaining individual differences (ID) in academic performance. The current paper questions this focus and investigates the predictive role of fluid intelligence (Gf) on developmental differences (DD) of school performance (DD). Data from 684 students from 6th to 12nd grades of a Belo Horizonte private school were analyzed. The IDs were measured through the equalization of annual Math, Portuguese, Geography and History grades. The DD were measured through the vertical scaling of Math and Portuguese grades of the elementary school students, and Math grades of the high school students. Gf was measured through the Ctif. A model via structural equation modeling was created, with Gf explaining the IDs and DDs. The model showed adequate data fit. The results indicate that Gf directly explains only the differences in development. Implications for the psychometric field will be discussed. [ABSTRACT FROM AUTHOR]
