Comparação entre média geométrica e médias ponderadas no cálculo de notas em disciplinas conjugadas de química

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.
