Initial and continuing teacher education are increasingly making use of remote and blended modes of education. Conducted in the summer of 2020 during the COVID-19 pandemic, this rapid review brings together literature and evidence to inform planning for remote and blended teacher education during restrictions in face-to-face teaching activity. The review consists of three main parts: first, a descriptive framework of modes of remote and blended teacher education; second, an exploratory review of the affordances and limitations of remote and blended approaches connecting the literature on effective teacher education with reviews of remote and blended approaches; third, a rapid review of evidence on the efficacy of remote and blended approaches, including of a small number of studies comparing these to face-to-face equivalents. We conclude that remote and blended teacher education is likely to become an increasingly important part of the teacher education landscape and there are plausible theoretical reasons suggesting that it can be effective with suitable design. However, we find too few studies presenting robust evidence to enable firm conclusions to be drawn on the relative effectiveness of modes and approaches. The review provides a foundation for further research and practice in this area.
