The 'Maker Lab' course, in which students conceive and set up their own experiments using affordable microcontrollers, required students to follow the entire arc of the…

In this new context concept approach, field research on the Trinidadian guppy is used as an appealing example of evolutionary change in populations. Pupils are asked to investigate the underlying mechanisms. In doing so, defects in their knowledge are revealed, in particular the role of meiosis in creating genetic variation. The reason for these…

In the framework of a curriculum reform in the Netherlands, an interdisciplinary open inquiry assignment has been introduced as a part of the final secondary school examinations. We developed and evaluated a preparatory open inquiry assignment to be used in science and mathematics departments of schools, in collaboration with each other: the…
