The authors studied 73 beginning chemistry students using the typical dimensional analysis technique and the variation technique. Student quantitative problem-solving performance was evaluated. Students using the variation technique scored significantly better (18.3 of 20 points, p < .0001) on the final examination quantitative titration problem than those who used the typical technique (10.9 of 20 points). American Chemical Society examination scores and in-house assessment indicate that better performing beginning chemistry students were more likely to use the variation technique rather than the typical technique. The variation technique may be useful as an alternative instructional approach to enhance beginning chemistry students' mathematics competency and problem-solving ability in both education and practice.

Students build selected mono-and disubstituted cyclohexanes using model kits, predict the most stable conformation and calculate conformational equilibria. Students also construct cis-1,2-dimethylcyclohexane and trans-1,2-dimethylcyclohexane using the Avogadro computational chemistry program, optimize the structures and confirm the lowest energy conformations. Students utilize a polarimeter to measure the optical activity of several unknown cyclohexane derivatives and identify them from a list of possible (±) menthol and (±) carvone stereoisomers.
