The commercial simulator Aspen Chromatography was used in the computer laboratory of a dual-level course. The lab assignments used a cookbook approach to teach basic simulator operation and open-ended exploration to understand adsorption. The students learned theory better than in previous years despite having less lecture time. Students agreed…
