The COVID-19 pandemic effected a sudden shift to online teaching, prompting teachers to implement many uncommon or even unusual teaching techniques in this unforeseen context. This precipitous move to online teaching has radically altered our teaching practices, where teachers have had to either completely do away with traditional practices or modify them in significant ways. One of the primary concerns of online teaching voiced by many teachers is to hold students' interest and keep them engaged in the virtual classroom. Another challenge has been to make students interact with each other and the teacher. The authors of this paper believe that Task-Based Language Teaching (TBLT) addresses these concerns head-on. There are two reasons for this: first, its emphasis on real-life language through meaningful tasks; and second, it is student-centered. This paper provides a brief background of TBLT and technology-mediated TBLT. It will show how some coursebook materials could be used in TBLT to help online learners improve their language skills. The paper also outlines with examples how technology-mediated tasks could be deployed to encourage learners to use language in productive ways. Finally, the authors discuss some of the anticipated challenges concerning the application of TBLT in online teaching and learning contexts.
