I think the study has a big flaw (and others like it) in that they give the impression that all the problems are due to remote learning in those two years.

1)Teacher burnout is real

2. Loss of income, severely sick family members and death during the pandemic are all problems that have affected the stress levels in kids which directly effects their learning abilities.

Aside from this, it’s not just about the kids being ok, many had old or vulnerable family members which would have definitely been put in harms way.

And also the teachers. Teacher burnout is real, pmuch of the country has real problems retaining teachers. Imagine telling them they have to come to work and either they or their family members would have passed aways or ended severely sick or with long covid.
