While this topic may not be at the top of governments’ agendas, the practical cases highlight how OER can give access to virtual laboratories, but also contribute to breaking down disparities in educational resources between countries, between educational institutions in the same country, and between formal, non-formal and informal learning settings. Studies and concrete cases show that the adaptation and augmentation of educational resources made possible by OER are necessary to ensure successful integration into new educational settings. Adequate educational resources have an impact on the overall performance of the education system, but the distribution of resources may be unequal at the institutional and national levels, as well as between formal, informal and non-formal learning settings. The advantage of OER is the ease of their distribution - both because of online distribution and open licensing.
