I repeat DD1 is irrelevant, school have never complained about her behaviour on a trip. I know what happens because she talks to me!
School have never been anything, but helpful and supportive with DD1. With their help, DD1's hard work and her peer group growing up, DD1 has friends and is a very happy sixth former.
Anyhow back to my totally NT very sociable German hating DD2.
Thinking hard about it I think I realise why she found immersive German so hard.
She likes to feel in control, she doesn't like to jump in and risk making a fool of herself. I assume that in immersive teaching you are meant to relax, have a go and not be expected to get it perfect first time.
She has spent her whole life hating art for exactly the same reason, she can't just let go and try ideas, it has to be exactly as it is in her head first time.
Despite this she is considering art as her reserve GCSE.
Why because she has a brilliant art teacher, who doesn't just complain she's lazy and give her detention if she's talking. No her art teacher speaks to her, finds out what she's interested in and encourages her.
Her art teacher does what good teachers do, they support pupils so they can become independent learners.
Her German teacher is not a good teacher, he does not reflect on his pupils learning or his own teaching. He didn't realise DD1 really hadn't twigged the absolute basics and missed totally that that meant she wasn't going to risk looking a fool by trying.
DD2 is far too sensible, far to respectful of authority and far to aware of how she looks to others to be very badly behaved ever, but German frustrates even her to the point where yes, she giggles and is silly. Sometimes if you don't laugh you cry or lose your temper and speak your mind.
Neither is DD2's style. Me yes I join in the odd inappropriate giggle, else I would get very very cross.
As I have said up tread getting very very cross is pointless because school isn't going to improve the situation.
