This document summarizes research into factors influencing South African lecturers' adoption of open educational resources (OER). It finds that practical pedagogical concerns about quality and relevance are more important than a resource's openness. Lecturers are guided by a belief in open education and improving quality by making materials open to greater scrutiny. Culture and structure shape agency differently at three case study universities. Individual volition is key to OER adoption at UCT, while institutional support is more important at UNISA. OER adoption is lowest at UFH where awareness and permission are lacking. The researcher argues individual ultimate concerns and how they are mediated by culture and structure influence OER contributions.
