Their can be no substitute for face to face teaching, I’m not even going to begin to question that, but the safety aspect goes beyond just the children.
It’s their at risk family members, their vulnerable or at risk teachers or their at risk family members, even their vulnerable or at risk peers. This is why we need these measures in place right now.
I get the argument about the negative impact on mental health that could occur by not being in school, so why is there not the infrastructure in place to mitigate for that? Because it has been taken away, shut down, cancelled, not taken seriously and most importantly not considered worthwhile by those in charge.
There is no real grand plan for making a transformative change in the lives of kids - Cov-ID or no Cov-ID. Just a repetitive cycle of changing measures that just get adjusted periodically to pretend that standards are improving.
