This paper contrasts measures of teacher effectiveness with the students' evaluations for the same teachers using administrative data from Bocconi University. The effectiveness measures are estimated by comparing the performance in follow-on coursework of students who are randomly assigned to teachers. We find that teacher quality matters substantially and that our measure of effectiveness is negatively correlated with the students' evaluations of professors. A simple theory rationalizes this result under the assumption that students evaluates professors based on their realized utility, an assumption that is supported by additional evidence that the evaluations respond to meteorological conditions.

REIS, J. C.; GUERRA, A.; BRAGA, M.: Ciência e arte: relações improváveis? História, Ciências, Saúde -Manguinhos, v. 13, (suplemento), p. 71-87, outubro 2006. Este artigo discute as relações entre ciência e arte, principalmente entre física e pintura, com o objetivo de apresentar uma abordagem cultural para a ciência. Dessa forma, entendemos que a compreensão dos conteúdos da ciência torna-se mais significativa. Abordamos diferentes momentos da história desde a revolução científica até o século XX. As relações aqui salientadas não buscam uma relação causal entre ciência e arte, mas sim uma visão mais significativa do que é o processo de construção do conhecimento. Assim, a ciência se desnuda para nós como parte da cultura e pode nos ajudar a compreender melhor o processo histórico que nos trouxe até aqui. PALAVRAS-CHAVE
