Capping Off a Unique Redesign of the Laboratory Curriculum
David Frohnapfel | Wed, 01/16/2019 - 11:43
A few years ago, the faculty in our department at Slippery Rock University of Pennsylvania decided to switch to an atoms first approach to the General Chemistry course. We took advantage of this change to systematically redesign the first semester of the laboratory curriculum to be a true “laboratory course” that focuses on laboratory practices, techniques, and equipment rather than on chemical theory.
