A coding scheme is presented and used to evaluate solutions of seventeen students working on twenty five stoichiometry problems in a think-aloud protocol. The stoichiometry problems are evaluated as a series of sub-problems (e.g., empirical formulas,...

Much research has been carried out on how students solve algorithmic and structured problems in chemistry. This study is concerned with how students solve open-ended, ill-defined problems in chemistry. Over 200 undergraduate chemistry students solved...

Solving open-ended problems, and the influence of cognitive factors on student success (2008)
Journal Article

Problem solving is an essential skill for undergraduate chemists to acquire. Many problem solving activities encountered on undergraduate programmes are algorithmic, and require lower order cognitive skills to be applied in order to reach a solution....
