Swedish teachers participated in an 8-week online course about open educational resources (OER) from March to August 2015. The course, called "Going Open Sweden," engaged 39 teachers across Sweden and was built around Wiley's 5 R's of openness - retain, reuse, redistribute, revise and remix. Some teachers created and shared their own OER on topics like book trailers and intercultural communication. While a few teachers regularly share OER, most do not due to lack of time or uncertainty about the quality of their work. The course was an eye-opening experience for participants about the possibilities of OER and getting over barriers to sharing educational resources openly.
