Footprints: Participant perspectives informing pedagogy for asynchronous online discussion in initial teacher education
… staff experience asynchronous online discussion (AOD) within initial teacher education. The aim is to explore participant perspectives, including expectations of fellow participants, with a view to informing pedagogy, defined as the relationship between teaching and learning (Loughran, 2006). The …
