"Shamster is clearly an advocate of the discredited ?Whole Language/constructivist? ideology which objects to direct, explicit and systematic teacher-directed instruction in the hierarchy of prearranged discrete reading skills, suggesting that it is somehow not in the child?s best interest to be properly taught the foundational skill of decoding in the manner proved by scientific, evidenced based research to be the most effective for all children, especially for disadvantaged children ? synthetic phonics."
Can I quote you in Pseud's Corner? 
What a load of guff.
No need to be gratuitously rude to shamster, by the way, just because you disagree with her views on reading.
Feenie - the problem with your reply - which I dare say is correct - that 85% of words are decodeable is that many if not most of the really high frequency words fall into the 15% - which is why Peter and Jane's 'key word' scheme worked so well for my, my DCs and numerous other children.
I never learned to sound out irregular words - I didn't need to - I recognided whole words which saved me a whole hgeap of time and effort.
Not saying that some kids might not struggle with this (those with poor visual memories?), but to deny all childen the opportunity to learn to read by this means because it is not suitable for all is just bizarre.
Should add my spelling (though not my typing, lo!) are the best of anyone I've ever met - that visual memory, whole-word thing again. MYDH, incidentally, who learnt to read with synthetic phonics, can't spell for toffee - because he expects things to spell as he's sounded them out in his head.
Basically, synthetic phonics is a great method - for learning other languages. Not English. I've taught thousands of foreigners English and unlike kids they can articulate exactly what does and doesn't work for them. If synthetic phonics was suh a great method we'd use it to teach non-native speakers to learn to read English too.
We don't.
You'd be laughed out of the place if you suggested using that method within an ELT context.
