To add some more recent data on this topic, look at the work of Valen
Johnson of the Duke Stat. Department as outlined in his NY Times article
of April 14, 2002. He shows a very positive correlation between grades
given and a positive student evaluation. i.e. the more A's you give, the
more studetn's will reward you. He has added anothe article at the Duke
web site www.stat.duke.edu/chance/153.johnson.pdf
