Longer school days- YEs or No ?

Education Minister Michael Gove says that our schools are underachieving, compared to Asian schools because our school days are too short and our school holidays are too long. Christine Blower from the National Union of Teachers argues that our children and staff spend longer in the classrooms than most other countries and also have some of the shortest holidays. Is she forgetting about the fact that we have 'half terms' which those countries with the longer summer holidays don't have, and maybe our schools spend so long inside the classrooms because of the lack of sport in our schools curriculum.
  There is a valid argument for both sides and there is a lot to be said for the Association of School and College Leaders statement that the quality of learning is more important than the amount of hours. On the other hand the argument for longer days and less holidays would have a massive impact on helping working parents.
   I remember thinking school was such a long day and could have happily curled up on my desk and gone to sleep after lunch. Thinking back now though I realise that this was when I was 14, and let's face it no-one likes school at that age. Now I have children of my own and work from home and  some days it feels like I get back home and half an hour later it's time to pick up from school. 
    It would be very interesting to see how people feel about this. Why not give us your thoughts.
