This session will provide an overview of taking an evidence and values-based approach to open educational practice. Using the University of Southern Queensland Library as a case study, it explores the planning process and outcomes of using evidence to demonstrate value and impact and engage with continuous improvement. This highlights a collaboration between two library teams working across evidence based practice and open educational practice. Participants will take away practical approaches to formulating focused questions around evidence-needs for open textbooks. The session will be of interest to any practitioner engaged or wanting to become engaged with evidence-based open educational practice, whether attendees seek to consider a broader approach to data gathering or are in the initial phases of developing a data plan. Discussion will further attendees’ understandings of how targeted and reflective questions can highlight the underlying values that surround our practice and build trust with the communities we work with. Throughout the session, practical approaches, such as data dashboards, will be shared. These practical examples will prompt reflection on how dashboards used for reporting and evaluation can offer authors’ access and agency to open textbook usage data. Attendees will take away practical examples and understandings of how a relational and values-based approach to both open educational practice and evidence based practice can be realised.
