shades1 - interesting points and question. The thing that stands out with synthtic phonics teaching is that it enables children to do precisely what you are seeking - work independently. There is no guesswork, no gaps in what can be completed, no limits to what can be accomlished, no heavy reliance on adult involvement and cues. There is a sense and purpose to it - it is directly relevant to the words children see on a page and want to put on a page. They have ownership of it. They see that they can do it - the rewards are rapid and continuous.
I always recommend Jolly Phonics - not because I'm on any kind of commission (I wish!) but because I have used it and really think it is fab. I love the picture references for the sounds which I find invaluable for display purposes and as a visual representation for the sounds which is not a letter or an object that has that sound at the beginning - very limiting and misleading.
There are heaps of resources other than those I ever used in the classroom which I think would much more appropriate for home use.
As for courses for parents - I'm sure there would be a huge audience for these although i don't know of any happening currently. However, I know 'whichphonics' is always looking at training opportunities (a company extended from the Jolly Trainers that exist through Jolly Learning) and also Debbie Hepplewhite at ink{http://www.syntheticphonics.comsyntheticphonics.com is embarking on new training so maybe she might consider a new audience. I would post on both of these sites' message boards and enquire. You could also contact your nearest Jolly Phonics trainer and see if they would come to a gathering of parents if you could collect enough together, although you would have to enquire about their fees which are individual to all trainers.
celia2 - a lovely comment, thank you! I love hearing those stories.
singersgirl - valuable comment. I love RM's 'Superphonics' books and they have also proved really popular with my classes.
I have, however, found that many children find the books that look the dullest, most tedious stories to me quite exciting - as they can actually read them themselves and that is the most motivcating thing for them.
