Globally, the spread of COVID-19 has led to the closure of schools, thereby accelerating the expansion of the online learning environment. Though, Fiji National University students' (FNU), had no option than to quickly adopt to this mode of learning, within limited period, their learning experiences are yet to be examined and documented. We used phenomenological study design to explore students' online learning challenges, coping strategies and their perceptions on the causes of COVID-19. A total of 120 in-depth interviews were conducted with FNU students, at different levels and colleges, and analysed thematically, using inductive approach. The three themes emerged included COVID-19 misconception beliefs among students, online learning challenges during the COVID-19 pandemic and online learning coping strategies during the COVID-19 pandemic. The misconception beliefs identified were natural occurrence, manmade for depopulation, unreal/fake and as a means of soliciting for funds. The challenges included ineffective tutorial sessions, lack of learning devices, unstable internet service, inadequate learning environment, socio-cultural practices, feeling of loneliness, anxiety and stress, and difficulties accessing online platforms and acquiring practical skills. The coping strategies used by students ranged from support from family and counsellors, help-seeking, frequent communication, time management, learning flexibility to control over learning environment. The findings highlight the need for policy makers, school managers, lecturers and other key stakeholders to address online learning challenges to improve online learning among FNU students. Relevant information should be provided on the COVID-19 pandemic to clear misconceptions.
