Enhancing teacher’s dialogic teaching skills in the post-COVID era: From using lesson videos to their corpora as cognitive tools

Due to the COVID-19 pandemic, hundreds of thousands of campuses worldwide were closed and teachers and students had to switch their teaching and learning activities to fully online mode. Using videoconferences to replace face-to-face teaching was a popular choice. However, during videoconferences, teachers often find it more challenging to engage students in learning. Further, with a large number of lesson videos generated through videoconferencing recordings, the effective use of lesson videos for teachers’ professional development needs further exploration. To address these issues, this paper proposes that teachers could consider using dialogic teaching to enhance student learning and engagement. Also, lesson videos should be transformed into corpora to provide suitable cognitive tools enabling teachers’ dialogic teaching.
