Social distancing due to COVID-19 has necessitated the immediate implementation of Internet-based English language teaching (ELT) in developing countries. This abrupt transition from face-to-face to online learning and teaching environment has brought up many concerns, particularly about maintaining ELT education in crises, one of which is how teachers scaffold students in Internet-based classrooms. Although there is an extensive body of research devoted to scaffolding students’ learning in face-to-face ELT classes, effective teachers’ scaffolding strategies in online classes are still worth receiving further scholarly attention. Therefore, this article reviews contemporary research on scaffolding strategies for teachers to apply in their Internet-based ELT classes. After discussing the inherent difference between scaffolding and support, and the relationship of scaffolding, support, and linguistic competence, the author synthesizes and systemizes scaffolding functions, intentions, and strategies applicable to the Internet-based English class. The author also suggests practical recommendations that teachers can utilize to scaffold students in differential teaching and learning contexts on the Internet. Finally, this article addresses some common challenges and suggests solutions for teachers to conduct scaffolding strategies effectively in Internet-based ELT classrooms.
