Openness means different things, and poses substantial challenges to the education system and to publicly funded institutions. The biggest of these perhaps is the increasingly polarised internal struggle faced by institutions as HEIs are expected to be open, transparent, and accessible, and at the same time requires them to be protective of their constituency and engage in competitive battles with peer institutions, private education providers, and the wider economy at large. The question arises, whether the concepts of a highly competitive global knowledge economy and those of global openness are mutually exclusive or whether institutions can balance these in their favour and for the benefit of wider society. The presentation highlights some of the issues that lie beneath the surface, leading to tensions in and around the education system. It will also touch upon the search for OER business models that are compatible with the demands put to institutions and that can secure their longer term future.
