Just coming back to the thread after church:
A few thoughts - I didn't read jound to rhyme with found, I looked at it, my brain process was 'that could be like wound, or it could be joust - I wonder which one it is meant to be....' and then started meandering off thinking about other 'ou' sounds, of which there are many.
It is virtually impossible to teach a purely phonics method. You're going to fall down on 'the' for example - that can't be found by blending sounds. So instantly you are introducing the idea that many words can't be found by blending. And then, when a child has grasped the phonics, grasped the fact that many letters/combinations have different sounds, grasped blending, and learned to READ not decode, and moved on totally from that stage, you're asking them to forget everything they've learned since then, in order to pass a spurious decoding test that some jumped up minister thinks is a good idea.
What's worse, you're going to waste time in class that you could be spending either reading fantastic books, or practising other literacy skills, learning to read words which are NONSENSE words, and don't mean anything. What the hell is the point of that?
I asked my 5yo if they practised reading words that don't mean anything, he said they did spend a fair bit of time doing that. Which is just rubbish imo, he can read completely fluently, he does not have a problem with phonics, and this time is wasted.
You might as well ask a very good swimmer to swim 10m in the shallow pool using doggy paddle and then penalise them for doing a bit of front crawl.
