I have 2 children. 1 in private and 1 in state (due to complex SEN).
My child in private school is being very well supported online with 3x weekly 1to1 zoom sessions with her teacher and well planned lessons and resources being posted out weekly.
Once they reopen they will stay open in the Summer to further catch up (they will have a 2 week summer holiday late August to give staff and students a break between terms).
The school is very hot on mental health and wellbeing and thinks that children suddenly being shoved into a new classroom, with a new teacher, having suddenly gone up a year group in September after 6 months off will be EXTREMELY detrimental to children. Not academically, but mentally and emotionally. I fully agree. And feel very lucky that our daughter is at such a wonderful school.
My child in State school isn't being anywhere near as well provided for with e-learning. I like my child's teacher and I think she is doing her best, that is just the reality of the situation. So far it looks like State schools will be closing for Summer.
Ergo, state school children are going to be hugely disadvantaged due to Covid. Even the middle class ones. The disadvantaged children (and my child and others with SEN, who are really going to suffer being out of school for 6 months), may very likely face long term life long consequences from this.
Teachers are working hard. I 100% agree. But I really feel something has to give.
The children need to go back to some semblance of normality after this. To their classroom. To their teacher. Ideally that will be in May. If not, as a Country we need to step up and be creative. If that means a few weeks of school in the Summer, then maybe we can support teachers with extra pay and bonuses. Or leave in lieu by extending a holiday in the next academic year that can be planned for (when they may be able to go on an actual holiday if borders are reopened for next year).
If the children can't make it back until September, perhaps they could go back early (late August once the weather has got rubbish as it always does in late August) into their old year groups for a half term. Make the October half term 2 weeks to make up for it. And have the academic year transition after that for next year.
Or as has been said upthread. Just let everyone repeat a year. Next academic year may have further lock downs going into Winter. That will be absolutely catastrophic to the mental health of school children having already jumped up year group (or school) that abruptly after such a long absence. That wouldn't just affect disadvantaged or SEN childen. A further winter lock down on children that have been off for 6 months and gone up a year group is going to be severely detrimental to even the strongest children in a school.
Repeating a year also has the benefit of raising the school starting age to 5, as we have the lowest school starting age in the World. Though admittedly the effect on universities would be complex. Maybe let this year's 6th form leavers go up if they are happy with this Summer's grading system. The ones that aren't can stay on and take the proper exams. (Also, means a lot less school leavers to tip out into what is going to be an impossible jobs market. Many school leavers this year will be unemployed for a very long time).
I don't know if any of the above are the answers. But, I really hope someone up high does have an answer.
