In summary, Emergency Remote Teaching (ERT) is a temporary shift to remote instruction due to crisis circumstances, distinct from online learning. ERT relies on technology-mediated learning and may involve various modalities beyond online learning. It differs from education in emergencies, which addresses longer-term solutions to emergencies such as refugee crises. ERT is characterized by its temporal, immediacy, and remote nature, with a focus on maintaining instructional continuity despite resource constraints. While the term ERT has gained traction in the research community, further clarification of its relationship to education in emergencies and development of theoretical frameworks are needed for smooth implementation in the future.
