BendyBob wrote a great post about why this is not so great at this age (although my DD is younger):
"Dd was set a project at this age. The list of requirements expected to be covered was long and exhaustive and was to be done over 6 weeks iirc. It way above her capabilities and she was always one of the higher achievers in class.
She struggled very badly with it buried under a heap of books 'researching' night after night getting no-where other than more and more upset and de-motivated. It def seemed a piece of work for someone much older."
Surely classwork would be better to differentiate between who can do what, and homework would be better set that all of the children are going to be able to turn something in. That way children who are unsupported at home / have parents who are not literate / have parents who won't or can't do it for other reasons / have special needs / are NT but not up to that level yet won't be shown out as being incapable of doing it to the expected standard which might well impact their confidence and enthusiasm for school generally.
Schools should IMO not be setting work that the majority of children will only be able to do with heavy parental input. What's the point? All it shows is who has parents who will sit down and help them, and simply totally shows up everyone else.
I am a person who follows instructions. If the school tells me that DD must independently research something and write about it then I think that is what they expect her to do. I would assume that they did not want me involved further than switching on the computer / going to the library with her / providing a pen and paper. I would assume that they had good reasons for stipulating this criteria and would follow the rules. And if she was unable to do it, then that is what they are looking to find out.
OTOH if they said help your child do XY and Z then I would follow the rules there too. But they don't seem to be saying that.
I don't see what the point of this sort of thing is at age 5/6/7 apart from to demoralise all but the top few and those with parents who will overlook the rules and do it basically for them?
