A commitment to sustainability is part of the fabric of OzU digital learning and teaching environment. As campus access for learning and teaching activities was extensively restricted for much of 2021, learners and teachers needed support to continue their activities with as little disruption as possible. OzU OLTE (Office for Learning and Teaching Enhancement) worked extensively with partners (particularly Information Technology Services and college learning and teaching teams) to appropriately adapt to the digital learning environment. From a sustainability perspective, increased usage of the digital learning environment is particularly promising as it offers future opportunities for students to make choices in how and when they learn. During 2021, OzU was forced to shift as much learning and teaching activity as was possible online when campuses were closed. The quick roll-out of remote learning means that students now have more flexible access to course learning materials when they need them. In 2021 OzU OLTE aired 5 best practice videos on its website, and organized 38 training with 3148 participants in total. As an example, The HyFlex class, thanks to its flexible structure and extensive technical equipment, aims to present all the activities to be carried out with the instructors in the learning and teaching process from a comprehensive perspective by integrating them from technical and pedagogical aspects.
