Reflection is a term often heard. But what is actually meant by it in the context of engineering education? How do we see reflection being applied in engineering, and where? To what could it contribute? And what are challenges involved? In 100 days, ‘Reflection in Engineering Education’ has been explored through journal clubs, conversations, presentations, a case pitching workshop, and peer exchange among scientific staff and educational support. This paper outlines this exploration with the aim of making reflection more accessible and concrete within the context of TU Delft Engineering Education.@en
