Inspired by a similar study by Osborne et al. we have conducted a Delphi study among experts to identify key concepts to be taught in engineering and technology education and relevant and meaningful contexts through which these concepts can be taught and learnt. By submitting the outcomes of the Delphi study to a panel of experts in a two-day meeting we were able to add structure to the Delphi results. Thus we reached a concise list of concepts and contexts that can be used to develop curricula for education about engineering and technology as a contribution to technological literacy goals in education.
