Molecular simulation

Kim Bolton and his colleagues at the University of Borås, Sweden, have investigated the use of a free computer simulation package, SimChemistry, with their third-year undergraduates studying an applied surface chemistry module as part of their chemical engineering degree.¹ 

The 16 students involved had not used this type of software before and were initially apprehensive about the time it would take to get used to the package and how much they would learn. They divided themselves into four groups and each group chose a topic to study. For example, one group chose 'animations of surfactants used as detergents' and they set themselves goals of producing animations showing a single surfactant molecule in water, micellisation of several surfactant molecules, and removal of dirt using surfactants. They had four weeks to complete the project and were asked to keep diaries to record their progress and thoughts about their learning. At the end of the project the researchers interviewed the students, analysed their diaries and tested the students' subject knowledge in an oral presentation.
