Many studies of college chemistry students have found a gap between students' success in solving computational chemistry problems and their success in solving conceptual chemistry problems. This paper examines college students' understanding of the concept of stoichiometry, the particulate nature of matter, and chemistry problem solving. This…

Peer reviewedNiaz, Mansoor – Journal of Research in Science Teaching, 1995
Exposure of an experimental group of (n=33) college freshmen to teaching experiments dealing with stoichiometry problems based on the concept of limiting reagent showed greater improvement in posttests than the (n=39) student control group and observed that some students protect their core beliefs by ignoring conflicting data.

Peer reviewedAlick, Bonita; Atwater, Mary M. – School Science and Mathematics, 1988
Discusses problem-solving strategies and the successful strategy used to solve stoichiometric problems in general college chemistry courses. Reports that rereading problems, recalling a related concept, and reasoning deductively/inductively are the most heavily used strategies among 13 categories. (YP)
