Imersive learning is certainly very fashionable, does that necessarily mean it's any good.
I don't know, I'm not a linguist, I gave up Welsh and French was absolute joy at 14 and disappeared in the science labs.
What I do know is that DD2 and two friends of DD1's who go to a respected private school (that's another world to my girls comp) disliked this way of learning intensely. One did get GCSE German having found she liked it once the initial teaching changed to something more structured, the other resorted to Latin as it taught very differently.
DD2 said it was bearable for French only because she'd done Frech Club (paid) at primary and she had some idea what going on. Some vocab and some idea of word order and grammar.
In German she was absolutely lost and the teacher has totally refused to acknowledge this or try to help in anyway.
"Just go on the internet"
Yes and do what? She hadn't a clue where to start, she was Y7 not Y12, she needed some pointers, some guidence, a textbook with some English.
The teacher didn't help at all, no guidence, no encouragement
Given German gets consistently very few pupils opting to take it and very poor results at GCSE and A level, something is seriously wrong, way beyond one pupil and one frustrated Mother.
No I've left it three years to late to complain, but someone must have in the past and in any case there is no way do school not know!
They have been in and out of Special Measures, they will have studied and had studied by external bodies every scrap of performance data.
School know this very small dept. and it's most senior and long standing teacher have very serious problems. Why they choose not to act I do not know!
