I do think people need to be clear about what's being suggested and why without starting with the anti-change agenda.
Firstly, nobody is arguing that there should be any less holiday or that holidays are not valuable. The holidays would simply be redistributed. There are all sorts of advantages to this but we need to be absolutely clear that there would still be ONE MONTH HOLIDAY IN SUMMER. Whichever way you look at it that is still a very long holiday.
Secondly, in fact, a lot of the research that found the negative effects of long holidays came from Scandinavia and America. I'll have a look for it in a moment.
Jabed, you really must stop assuming that your miniscule and unique experience of education applies to everyone. Just because your school tried it and according to you it failed does not mean that it would necessarily fail for everyone. It has been agreed that to be truly effective it would need to be national.
Finally, once again, in spite of what your personal experience might tell you, the RESEARCH suggests that most children go backwards during the 6 week break losing a great deal of the knowledge and skills they had gained during the previous academic year. This has a cumuluative effect over time such that many children are not achieving the sort of progress they could and should be.
Where this is more pronounced in kids from more deprived backgrounds (and I do find the sort of dismissal about such kids on this thread really quite disturbing) it actually affects ALL kids. Middle class kids plateau and that's only because mummy and daddy can afford the time off or the holiday clubs and nannies in order to intervene.
Even though dp and I are teachers and we share the long summer holiday with our kids and do lots of lovely and subtly educational things together, I notice the effect on them. They make massive progress all year and often especially during the summer term and then a lot of this is lost rather than consolidated over the holiday before they make the transition to the next year. It's also a very big adjustment back into learning in September and each year teachers spend a good few weeks just reestablishing routines and catching up on last year's learning.
By the way, the research says that there is a particularly marked backward jump between year 6 and year 7 when children have to cope with the psychological upheaval of a school more. It is absolutely typical for children to regress during year 7 rather than making progress. I would also say the break between year 11 and year 12 and year 12 to year 13 is far, far too long and disadvantageous.
