Setting is better than streaming, I think, ie kids are 'judged' on their abilities in each subject, and put in an approriate group. Streaming is when you have general streamns that put yo in top sets for everything etc regardless of your ability in that particular subject IYSWIM....so I was streamed into 'top sets' because on average is i was very good. I was crap at maths, but was still in the top group because U school I went to streamed, and didn't set.
'Bottom sets' Ah well, that is a difficult issue.
One big problem is that the kids come in, knowing that they are in the 'bottom set' (however the school dresses it up to hide the fact), and feel that they are sure to fail. So the first thing that you have to do is to build up their confidence.
Hoever it is totaly unrealistic to take children who are woking towards a level 3 (average end of year 2) and have them working with kids who are on level 7s (top end results of year 9) and expect the lesson to work and satisfy all needs.
If 'bottom sets' are small, and children have some SEN support, then they can make real progress. The real issue comes when children who are disruptive end up in the bottom sets. Often these are actually quite able, but have decided that school is not for them, so their behaviour deteriorate. And then you end up with a situation where the least able children are put in a class with the least well behaved. And then the situation develops where no-one learns anything.
Best way to sort this is to take the disruptive children out of the class .....we do this by placing them with work in a sixth form lesson. Its amazing how well they can work when there is no appreciative audience to play towards.
There are numerous issues in secondary education. Children at the bottom end of the attaiment ladder get a really rough deal. Children at the top end may sometimes be bored, but IME the two things are not comprable.
the G and T scheme (and I've done a fair bit of work in the area) is flawed from the outset. It makes mistakes in correct identificatio, the 10% issue is farcical, it is badly funded and the money goes on one off trips , which while they might be fun, do nothing really conreauctive for most able children. It is a sop to the middle classes who are thwarted in their wishes for grammer schools.
If we want an education system that values all children equally (and I think that everyone would agree with that), the simplest and most cost effective things would be to take the millstone of paperwork and 'standardisation' from teachers necks, and let them use their professional ability and understanding of their students to best effect.
Bright kids don't need trips to the local museum (for the most part), they need teachers who, on seeing that they have covered the work for year 4, are free to send them to the library to have some intelectual fun, rather than having to give them more farking worksheets, this time from the year 5 sylabus.
But when would the government ever bother to ask the teachers eh? After all what would we know about it?
