I've been thinking about the solutions as someone who has experience on various sides of education, working and being a parent.
It would be more practical to go back to open to working and vulnerable homes. This would reduce class sizes. IF working parents don't want to take the place, excellent. Similarly with the vulnerable unless it's in their interests for them to be in school - using whatever resources they used before CV, targeting those whom they know that need it.
Schools continue with staff moving around the schools. Due to lower numbers in the school fewer teachers would be needed and could be rotated like they did with NHS staff for your face-face. Plus we all know how much time is spent them moving around, settling etc. Of course the nhs on/off style would apply to the whole school.
With correct lesson plans we know HLTA's are more than capable of also teaching many schools relied on them before CV. Schools to use to their potential, and don't forget many TA's/HLTA's are qualified and sometimes specialized teachers. Same with some other child oriented services who staff are CRB's and furloughed at the moment. Their contracts are directly with the council so shouldn't be an issue if they can, to work in the schools. Plus no additional money is required. Of course, no sanctions to those who won't agree to the temp contract change.
So now we are left with classrooms in a school with a teacher and relevant support support staff. SD'ing will be better in some schools than in others, this is true, however those schools could be given more focus and possibly using those other council run buildings that currently are closed. Thus getting some of that buildings staff off furlough.
But, but, but kids at home - through utilising support and other staff to their potential you do clear up some teachers, including the ones that should be shielding. They are the ones uploading content to whatever online learning portal the school use. IT would also help if there was a centralised lesson plan system - it's baffling that with all the tech around us, every teacher in the country has to waste time on them.
The class students would be sitting at their desk at the start of the lesson (well there would be less disruption) thus giving an extra 20 minutes? for teaching. The online students again the same.
Imagine what could be achieved by all those extra 20 minutes in a day?
Of course it's just a pipe dream because the government never fully followed through on getting school kids online. Even though it started several years ago and homes were also given free connection. Was mentioned again this year, and yet here we are with many still waiting.
