MrsDeVere, I think it's interesting too, and there's always ideas to be shared about how certain problems could be overcome.
Without wanting to sound like I'm creating barriers where there should be none,
Assisting a child in a toilet is possible if the toilet is accessible. In my schools building this would mean children in Y1 and reception being unable to use their little child sized toilets in their own classroom. They would have to go to the other end of the school, either alone, or with a member of staff who would be more use to the class as a whole in the classroom, just on the off chance that they might need help. If they had had an accident, their things to change into wouldn't be nearby. So on the whole, far from ideal, and possibly detrimental to the class if this were to be enforced with our building the way it is now.
Comforting a child is possible from a chair. yes, in most cases it absolutely is. Although not so much when the upset child is lying on the floor because they have hurt themselves and need to be picked up, or they have gone into the playhouse or shed or the little shelter in the wooded area, or at the top of the climbing frame, and need someone to go and be where they have chosen to be while they are comforted. Not a massive problem (except with the injured child lying on the floor) but IMO, a reasonable consideration for the school to make.
Teaching children to use play equipment does not require physical demonstration and you can help a child get down/up from a chair. I do some exercises with the children in my class that do very much require physical demonstration, the quickest example I can think of is with a child who doesn't have recognised SEN as he's still only reception, but is very uncoordinated and 'clumsy' for a lack of a better word. He has been doing exercises like rolling a ball from one foot to the other, moving his ankles round in circles and that kind of thing. He very much does need a visual demonstration. As I said earlier, we have a massive wooden climbing frame, and I have only been able to encourage some children to use it fully and be involved in 'risk taking' (seemingly v fashionable in the EYFS at the moment) by being able to stand underneath then while they try the monkey bars, or swing themselves across to the firemans pole.
None of this is essential for teaching the academic stuff, but tbh, I think it is important that a KS1 teacher be able to support all areas of learning.
