Hi everyone I am starting a secondary PGCE next year and spending quite a bit of time observing lessons in a local secondary this year . I also have three kids of my own (yrs 6, 5 and 3 at the mo) I've noticed this in classrooms, and in my own parenting - but grown-ups seem to be particularly worried about kids rocking or tipping on chairs. I remember once myself, in probably year 3 or 4, tipping right back and falling over, but I have never ever. seen anyone else fall when tipping on a chair. I do it myself reasonably regularly (including finding myself doing it sometimes when observing lessons!) Still, it's a constant refrain to my kids 'all four legs of the chair on the floor please' and I am doing it to the children at 'my' school, now, too. I wonder why? Is it because we're worried they will fall and crack their head open / chin themselves on the desk (depending on the direction of the tip)? Is it because it's the thin end of the wedge in terms of behaviour and needing to sit still to pay attention? Is the rocking movement of a child just distracting to the teacher? If one does it will all of them end up doing it in a way to play up to the teacher? Or are we just repeating cautions because our parents and teachers told them to us? I would be really interested to hear people's thoughts on this as I can't get it straight in my head. I know there are plenty of other more pressing behaviour issues, but I'm intrigued, particularly because I think for me it's a way of subtly changing position and getting more comfortable (Maslow's hierarchy of needs), and since age 7 I have been able to balance perfectly well, thank you, on the chair.
