Mixed ability maths grouping

[mixedabilitygrouping]

I'm a regular here but have name changed.

I'm just at the end of the 2nd year of a B.Ed and I am doing a research project on Maths mastery in primary schools (linked with Singapore maths and PISA), I've got to collect some data on mixed ability maths grouping so am asking begging if anyone would be able to complete a very short (5 questions, not remotely mentally taxing!) survey?

I'd be truly grateful :)

Thankyou everyone, for the completed surveys AND the discussion, I've got so much food for thought for the whole research project now, it's really helped I really, really appreciate it (between here and Facebook I've got nearly 275 completed surveys!)

All maths classes anywhere in the world are mixed ability classss. There isn't a class where every kid has the same ability. Even if they do, after a while they will all be at different stages. So the idea that certain things work in a mixed ability or setted class is false anyway. However, a setted class will have less of a spread, which makes it easier to have everyone achieving an acceptable minimum level of understanding before moving on. One thing that nobody pays attention to that kids who don't understand things straight away in Singapore will work hard outside lesson to catch up with their peers through help of parents or tutoring. It is always easier if your parents can do Maths or can pay for tutoring.
If you teach fractions, how long will you carry on doing it if some kids lack the basic understanding of factor and multiple and forget things that were taught the previous day? What about the kids who got it already? There is only so much you can do when the problem needs new concepts and techniques to make it more interesting or challenging.
I was taught as a kid using part of the Singaporean approach, especially the bar method. It was an overkill and I got really bored pre-Algebra. As soon as I learnt Algebra, I never thought in the same way :)
