Sorry to be getting back to this thread only now!
Thank you for all these extremely helpful replies! And I'm interested in how varied the responses are too (like dc themselves I suppose!).
Cece and Raisinboys I'm relieved to hear that it is not just my child who is lacking in self-determination and initiative at this age!
Thank you very much for the practical suggestions Swan and Honu!! I will indeed suggest breaking up the hour, encourage her to do it at a set time, try and build up that time incrementally, and try and introduce rewards on completion (without getting too involved according to the teacher's instructions). It's a difficult balance though!
Swan She is used to working for fairly concentrated periods of time at school but I think you have hit the nail on the head when you point out about her not having the sense of anyone working alongside her. She is very bad at being completely on her own. I might just have to do paper-work (as unobtrusively as poss) in the same room for a while (again without interfering too much). (Sadly, reading doesn't count because dd has no problems at all with that, in fact I have trouble persuading her to put down her current book and do her hwk!!)
Need to encourage all of this without being over-controlling or steering too much, because, as you say, the ultimate goal is for her to be able to study independently.
Honu thank you - much appreciated - I will indeed pm you over the weekend.
Lonecatkitten I think my dd might actually achieve one hour working independently if it involved doing the hwk your dc have been set - which sounds really interesting! Sadly we live in a country where the the teaching methods are very formalised and most of the subject matter (with a few exceptions) is as dry as dust!!
Redskybynight yes, dd also gives a good impression of working for 50 minutes out of the hour, when it is really only in the last 10 mins when she actually gets down to it.
Thefirstofhername I'm interested in the distinction you make between work that has been set and independent work, because to be fair to dd, she has got a lot better at doing the former. She is nowhere near achieving the latter though yet!
Dh and I were discussing this earlier today. He said that he got hit by his teachers (40 yrs ago!) when he was 11 yrs and didn't know his set work which is obviously as far from the ideal as you can get but there was certainly no question about who was in charge! I wasn't given much hwk at all at that age but when I was, I was firmly directed ie I knew exactly what to do, how to do it and told when I should do it.
Am I right in thinking that dc are expecting to be more self-determined nowadays? (Not in life in general perhaps but wrt study?) I'm not sure I would have known what to do with that "power" at that age... I'm not sure I would have used it constructively tbh.
However, I take heart from your words Honu that 11 yr-olds can do it if taught properly!
Thanks again everyone - this was really helpful.
