Hear, hear Ferguson.
(I'm a primary school teacher)
Dancergirl - school is so different now to when we were at school (I'm late 30s). The expectations are different (far higher generally) as are the outcomes.
My DD is just 6 (July birthday). She has just finished year 1 and I am astounded at the quality of her writing. Her teacher showed me a piece of completely independent writing she had done in which she had used connectives (and was quite rightly proud of it too having told me that "I sometimes find it difficult to choose the right connective" at Easter), used !, ? and " " correctly and started a sentence with "unforchunitly".
Should we have ignored the good/correct use of punctuation? The quality of the story? The meeting of the criteria is general because some of the words weren't spelt correctly? No, because that would be ridiculous.
Yes, they used to focus on the spellings when we were younger, but at the expense of pretty much everything else!
I know for a fact that I wouldn't have written a paragraph like that during the same week I turned 6 and I have a first class degree!
Many of the spellings are left uncorrected for the reasons other people have stated, but when you consider that many of the children are attempting words/pieces of writing that are of a higher standard that we used/wrote at the same age, I think we can probably cut them and the teachers some slack!
It's not about not 'upsetting' the child, it's about creating a working environment and 'space' for them to explore their ideas without sweating the small stuff.
