electra - I'm in Kent (but soon to move, for schooling, hence this thread, really). We exchanged a couple of emails on ABA/VB a while ago when I was first looking into it all.
the autism=visual learners has been a real bugbear of mine (and I know cyber & I have been through this on a few other threads, too). dd1's old sneco was obsessed with getting dd1 to use pecs. dd1 is verbal, and willingly so. if there is a particualr phrase you want her to use, it is as easy to get her to learn that and use it as to understand about the pecs cards thing. but still they persisted. dd1 just walked off (can see her point, tbh, but now we have to undo all that "switched off from learning" that they created). There is a possibility that the teacher, in stopping dd1 to prompt with the card even though dd1 was going to the table anyway, was asserting that she (the teacher) shoud be listened to, as dd1 had been ignoring her until then (she followed my cue to go to table). so backing up something that dd1 was willing to do with a picture cue, so that the obeying of pictures is established, then go on to present another card and expet dd1 to follow the instruction form the teacher. sorry, not a good explanation - was up all night dealing with vomity children!
I agree totally about the teacch concerns. that's exactly why I have always thought of it as wishy washy, because there is no actual evidence to back it up, and also, other than being an approach used to control behaviours, etc, no-one seems to know what it actually is, yet most special schools use it. It's just a buzzword. they might as well say they take an old fashioned view of avoidance behaviour (ie gently insist that the child join in at least a littel).
also agree that each child's case should be looked at individually, and what is suitable for the child should be provided. but so often, people (schools) don't know what they are providing anyway - so many places say they don't/won't 9quite often emphasis on won't) do ABA, yet do do pecs, which is pure ABA - action/immediate reward stuff. It's all madness.
dh and I talked a lot about this last night (in between changing pyjamas/sheets/scrubbing carpets ) and we are going to go for the nursery place. It will be half dys for dd1, and they do at least know someting about autism. dd1 won't be left to drift arond ("freeplay". huh.) as there is a structure in place, and they do seem to get results.
In the meantime we will continue with our part time home vb, and between all that, hopefully we can get dd1 going in the right direction.
Now we just need to find somewhere to live, and pack up and move. jol good, shold be done by the weekend
