This article discusses a dilemma that engineering educators encounter when attempting to develop pedagogical methods: that of finding efficient and scientifically valid didactic practices. The multitude of methods offered by educational consultants is perplexing. Moreover, the popularity of commercially offered solutions such as learning styles testing makes them appear attractive. The study presents one case of application of learning styles, the consequent problems and evaluation of results. It concludes that the use of learning styles is not supported by current pedagogical theories. Practices to foster interdisciplinary understanding between learning sciences and engineering are proposed in order to improve engineering education, most notably collaborative projects between university departments.
