Open practices in education focus on the actions of learners and teachers regarding openness. The sharing and collaborative creation of open educational resources is at the core of such practices. Digital infrastructures do not only provide environments for these kinds of practices but reflect ideas and implications of open practices through the functionalities they offer. Those infrastructures can be seen as drivers for enabling open practices to become default. However, a common understanding of open practices has yet to be defined. As such, designing digital infrastructures that foster open practices might be a challenge. This chapter shows the relation between open practices and digital infrastructures.
