DD has started at a good, selective, private girls' day school in London. I am dazzled by everything but the MFL teaching. It's no different from when I was a kid at a "bog standard" comp in the rural, southern USA. It's: here is a list of vocabulary words- memorise them; here are some grammar rules- memorise them; if you miss a single accent mark in the spelling you are wrong; etc.
From my personal, lived experience, this is not effective. A big part of fluency is repetition of words in context. Even if you manage to retain a list of vocabulary in your memory, it won't be instantly available to you as you try to speak at normal speed. Also, a big part of becoming fluent requires engaging in the material and just having a go. Creating so much tension in the DC about making a petty mistake is very inhibiting and counter productive. Instead of seeking to engage and communicate the DC try to hide.
I used to speak four languages. The two I learned as an adult, were easy come easy go. The second language I learned as a child, before puberty, I never forget. I get rusty, but I retain a good 80% and get up to speed quickly after being in the environment again for a few weeks. I can think in this second language and don't have to translate back and forth in my own mind. It was the same with the other two that I picked up out of necessity. But after 15 years I have forgotten them almost completely.
I wonder if learning a second language as a child changes your brain so that you can acquire additional languages more easily as an adult than the monolingual can. I also wonder if we should be concentration MFL more on younger children.
Also what is the purpose of MFL education in Britain? Is it to communicate on holiday? Do business? Or have a precise academic understanding of the language and literature. I have a feeling the emphasis is on the latter rather than the former.
