Discoverability of OER: The Case of Language OER

2021
One of the obstacles that prevent the widespread adoption of Open Educational Resources (OER) is the difficulty to find appropriate OER for specific educational objectives. This paper investigates this discoverability problem by searching for OER in eleven well-known repositories of OER (ROER).

Oer

2020
Oer begint met een fascinerende hervertelling van het scheppingsverhaal. Proton, een minuscuul deeltje dat vlak na de oerknal ontstaat en door de ruimte vliegt, neemt de lezer mee op een duizelingwekkende reis door de tijd, van oerknal tot de evolutie van het leven tot de dagen van Jezus en het leven van nu.
