Open educational resource (OER) as free teaching and learning materials can contribute to the collaborative design and development of teaching. To support higher education teachers in their work with teaching in general and OER in particular and to encourage their use of OER, it is necessary to pay attention to their needs and requirements. This paper presents the results of a research project, identifying the usage behaviour of German-speaking higher education teachers. In an interview study, they were asked about their experience with OER to get detailed insights into their practices concerning their 'use' and 'revise' of materials. From this, four user types were derived according to different OER activities, such as creating, reusing, editing, and publishing OER, and their scope. Finally, these user types are transferred to considerations when designing OER infrastructures and establishing support options. These are aligned with the specifics of each user type, making the research findings a complementary contribution for application in higher education.
