The SARS-CoV-2 / COVID-19 pandemic (2019 - 2023) disrupted all of humanity and fundamentally changed human understandings of the world, people, science, risk, and specifically for this project, how teaching and learning has to be done in a context of social distancing and biosafety. Many view the pandemic years as lost ones, with massive fallbacks in learning acquisition. This work explores what teaching and learning techniques are used in formal, accredited learning (pre-K16 and beyond); nonformal learning (non-credited courses); and informal learning (spontaneous and incidental learning acquired through living). How are people adapting today, and what theories, techniques, technologies, and approaches are they using, and why? Are these approaches effective in objective and empirically observable ways? This work will serve as a debriefing in a sense but also a map of a way forward in another. The losses from the pandemic have been severe (with losses being identified even into the present), even as people are striving to recoup what is possible and looking for silver linings. The time of extended isolation may have enabled some rumination and experimentation as well.
