In a survey of teachers from Lithuania, Portugal, Finland, Belgium, Romania, Austria, Sweden, Greece, United Kingdom, Bulgaria, Turkey, and Ethiopia who used OERs: “Eighty per cent wished that resources would be easy to use, and 70% needed them to be easily adopted for their lessons.”
The reputation of the organisation providing the OER is also important:
“Eighty-ﬁve per cent said: ‘I trust organizations with good reputation’.
Fifty-ﬁve per cent said: ‘Quality for me means that the resources come from an organization with good reputation’.”
“Users also trusted quality instruments such as good ratings (67%), use-rates (53%), and peer reviews (70%)”
