ABSTRACT
The meaningfulness of the current educational landscape, where online learning is heavily practised, is often questioned. Experiential learning focuses on the learning process that learners undergo. It is believed to help them to make sense of the learning process through active participation and meaningful reflective practice. Debriefing is an experiential learning strategy that requires learners to reflect on their learning experiences and connect them to real-life situations. However, only a limited number of studies have investigated the use of debriefing in the English language teaching and learning context. To this end, this case study aimed to explore the effects of debriefing in online ESL classrooms and the challenges of online debriefing. The case study was conducted in Bintulu, a town in the Malaysian state of Sarawak, and involved two teachers who were actively conducting online ESL lessons during the COVID-19 pandemic. Data collection was conducted through in-depth interviews and observations of recorded online ESL lessons with a focus on the debriefing sessions. The findings indicated that debriefing has positive effects on active English language learners as it helps to improve their critical thinking ability as well as their oral and written language proficiency. The challenges of debriefing in online ESL classrooms include learners being hesitant to talk during lessons, teachers facing difficulties in using appropriate debriefing questions, as well as various technical problems.
