Direct linkDonaghy, Kelley J.; Saxton, Kathleen J. – Journal of Chemical Education, 2012
A three-step active-learning approach is described to enhance the spatial abilities of general chemistry students with respect to three-dimensional molecular drawing and visualization. These activities are used in a medium-sized lecture hall with approximately 150 students in the first semester of the general chemistry course. The first activity…
