Yes Misfit the teacher could tell them, examine each child in detail for bookbag, water bottle, lunch box, jumper etc etc, but that is not going to encourage their independence.
I disagree, because repetition of a task, and helping those children get into a routine so that it becomes second nature, is helping them to become more independent, I think.
And anyway, I wasn't suggesting anything like that, just as part of the going home routine, that the teacher says something like "Time to get your coats and bookbags...now, has everyone got their coats on, and their bookbags? Then line up."
Like PP said, setting them up to forget, and then punishing them seems....weird! It's a partnership, surely. How would the teachers feel, if the pupils repeatedly turned up in their pyjamas, two hours late, because their parents were teaching their DCs to be independent, and so hadn't said "Time to get up and get dressed, ready for school!"
Obviously I exaggerate, but by point is, school life would be a lot less smooth if we didn't remind our DCs to do things, reminding pupils to get their book bags - really? It's just facilitating their independence, and enabling them to do their HW.
Parents in our school even have to send out reminder texts to parents! We all got texts the other day reminding us that forms and money for the next school trip were due in and some parents have forgotten to hand them in.
It would be interesting to know if that happens in OPs school!
