OP- I can't believe, that as a teacher you don't see the need for G&T.
I recognise that there is a whole world of difference between truly gifted and the schools' definitions, but I think both are worthy of a thread.
True G&T children deserve a thread because they are very different from their peers and I'm sure that this would bring up a whole range of issues, as other posters have expressed.
But G&T children as in the top 10% deserve a thread too, because there are different but still problems in dealing with them. I know that as a teacher, there can be a tendency in schools to deal with the G&T kids by giving them 'more' work. But more work of the same level is not differentiating properly. When I studied my MA in Education, we looked at this issue and noted that many teachers do simply seem to assume that it is enough to simply give the child more work. Yet this is not good enough. I know that it is something that I do struggle with at times. I only teach 'A' levels now, but struggle to find appropriate undergraduate level work for my brightest, to really stretch them - particularly the Oxbridge candidates, who have often read ahead, know the topic before you even introduce it and so on... So yes, it is a real challenge finding them appropriate work.
Also, as a mother, I find this to be an issue too. My daughter is bright. She is not 'gifted' in the traditional sense, she is only 'bright' but that still poses challenges, For example, she has learnt some things not typical of her age. Helping her to do this, can be a real challenge. For example, at 3 she learnt to tell the time (1/4 to and 1/4 past). I really struggled to find an age appropriate book to help her learn this. You can't ask friends in real life, because it looks as though you are bragging. Equally, you can't post on the ordinary education section, because that too looks like you are bragging... so what do you do? Spend loads of money until you eventually find something that works, or find a 'safe' place (like this section) where you can ask knowing that you will get genuine help and support, without being accused or having others sneering at you? (Incidentally, in the end, someone suggested a Maisy book, which we bought and did the trick!) Our current issue is to find books that are appropriate for her reading ability, but ones that are also appropriate for her age and level of maturity.
Being G&T in the sense of just being bright is not the same as being gifted in the traditional sense, but it does have its own difficulties. I know that primarily as a teacher. Given that when parents posts about G&T on the education section on here, they seem to get a lot of flak about boasting etc etc... I think a G&T section that other people can easily ignore is the most sensible solution. It provides help and support for those who need it, whilst not being in the faces of those who don't want to see it.
