Using variation to enhance learning in engineering

This paper reports on an attempt to enhance the learning outcomes obtained from a Computer simulation aimed at extending students' understanding of distillation. The approach taken draws on a contemporary education perspective known as variation theory The design uses the notion of a learning study to identify the key aspects of the learning situation. In-depth interviews were used to gain insights into the learning outcomes of the redesigned simulation experience. The overall finding is that the students were able to draw on their previous knowledge and expand it in ways that made them feel positive about the experience.
