Abstract
This study investigated the role of academic library staff as change agents for implementing Open Science practices with the graduate students of Kumasi Technical University (KsTU) in Ghana, with the aid of Rogers' (2003) Diffusion of Innovations theory. The study employed a concurrent triangulation mixed methods design, which included a questionnaire for the graduate students and semi-structured interviews with library staff members. Awareness of Open Science practices was moderate but fairly even, and was not often translated into actual practice, particularly in the use of the institutional repository, where the relationship was the strongest but also with low uptake; a low level of uptake was also observed with students aware of the practice. As change agents, the library staff used orientation sessions, workshops, and individual consultations as their primary methods, which are appropriate strategies given the library's constraints of policy gaps, limited funding, and uneven support from the Library Department, but not a shortage of effort. The study calls for a formal, institution-wide Open Science policy, and training to be carried out early and not as a one-off activity near graduation
