“…The majority of previous research activities carried out in the period 2011-2020 primarily focused on documenting the adoption and growth of public OER policies worldwide and did not investigate the role of IGOs OER policy instruments on the development of the reported governmental OER policies (Hylén et al, 2012;Hoosen, 2012;Orr, Rimini & van Damme, 2015;COL, 2017;Inamorato dos Santos et al, 2017;Ossiannilsson, Hakan & Wetzler, 2020). The published information on this topic is limited to several studies or reports examining the effect of some OER policy instruments, such as technical assistance or discursive dissemination, of IGOs such as UNESCO, COL or EC, on the development of governmental OER or Open Education policies in a specific country or a group of countries in a particular geographical region (Inamorato dos ORS Impact, 2015;Abeywardena, et al, 2018;Abeywardena, et al, 2019). There is not yet a clear understanding of the instruments of OER policy influence, collectively applied by different IGOs, in the context of governmental OER policy processes and their effectiveness.…”
