Resumo
Theory/Lab courses in General and Physical Chemistry
attended by freshmen students of Pharmacy and
by second-year students of Food Engineering were
evaluated using statistical analysis on the resulting
scores calculated by geometric and weighted means
as a tool for the allowance of both a better teaching
practice and a better teaching process. The obtained
results indicated that there were not statistical differ -
ences in the scored means although geometric mean
scores showed a positive bias resulting in scores
systematically higher than the ones for the other
weighted means. Since in Chemistry a student needs
to have solid background both on theory and lab
works, and as a result of summative evaluation geometric
mean seems to attend this pre-requisite owed
to the fact that the students have to equally dedicate
to both lab and theory courses.
