This systematic literature review of 36 peer-reviewed empirical articles outlines eight strategies used by higher education lecturers and students to maintain educational continuity during the COVID-19 pandemic since January 2020. The findings show that students' "online access" and "positive coping strategies" could not eradicate their infrastructure and home environment challenges. Lecturers' "learning access equity strategies" made learning resources available asynchronously, but having access did not imply that students could effectively self-direct learning. Lecturers designed "classroom replication, online practical skills training, online assessment integrity, and student engagement strategies" to boost online learning quality, but students who used ineffective "online participation strategies" had poor engagement. These findings indicate that lecturers and students need to develop more dexterity for adapting and manoeuvring their online strategies across different online teaching and learning modalities. How these online competencies could be developed in higher education are discussed.
