I'm not against visual prompts, not at all, but I do wonder if a good amount of their effectiveness is simply down to the fact that if a 1:1 or teacher takes the time to print out and laminate a sequence in order to help a child then they will make sure they go practise the sequence over and over.
Is it the practising that makes a difference or the visuals?
I mean, if you didn't have the visuals, but talked through the sequence/story board/visual timetable etc regularly instead, would it have the same effect. Is the visual prompt really just to prompt the teacher?
