Dd in year 4 is streamed for numeracy, literacy and phonics. This year she is in single sex groups and admittedly is loving it away from more disruptive boys. Is this a widespread strategy nowadays and is there evidence that this works? Does this happen in your school?
There are some of us who firmly believe that girls and boys need different styles of teaching and that same sex is the only way to go. I don't think boys are disruptive just that their needs are different to girls.
