DD is in Yr 7. I'm having a go at teaching her French very informally - saying the odd sentence in French, doing occasional CDs in the car (Pimsleur), occasionally watching a French children's DVD or reading a French toddler book with her. She has also started to do a bit of DuoLingo online. She is quite keen on French now.
After a few months of this, she understands a lot of French.
My older DC has been learning French in private and grammar school for 6 years, and is in top set.
The 2 DC found an online French test. Younger DD got a higher score. Her pronunciation is also better.
I'm sold on this informal method now. And what on earth are the modern language teachers doing? Older DC can still say and understand practically nothing. Why have the schools (those I know) got rid of language labs, for instance? Unless my DD is a great linguistic talent, it's not that hard.
