Investigating students’ lived experiences of online learning can inform us on how best to teach them. In this paper, we harness the insights gained from pandemic teaching and learning to inform sustainable approaches. Theorized in relation to Ben-Eliyahu’s sustainable learning in education (SLE), this article offers insight into what tertiary teachers can do to support students with sustainable strategies, as well as how students can develop long-term learning strategies. We draw upon the research on the perspectives and experiences of New Zealand university students studying online in 2020 to inform SLE in online teaching and learning in the long term. The researchers collaborated with student associations to undertake a survey exploring the students’ experiences of online learning. There were 952 valid survey responses from all 8 New Zealand universities, complemented by 20 individual interviews and 9 focus groups involving 43 student participants, both on and offshore. Our findings indicate that students regard support, communication, and engagement as key areas where they experienced challenges or helpful practices, and where there are sustainable directions for future teaching and learning. We propose support that institutions can provide to both students and staff for sustainable strategies.
