Although I feel that learning languages is really important, some people with developmental and/or learning difficulties have enough trouble with learning one language. We should be teaching second languages earlier though - studies have shown that language-learning is a skill we need to keep using from when we're little otherwise we struggle.
We also need to change the things children are taught in language lessons too. How often do you need to say 'I have blond hair and blue eyes'? 'I'm allergic to ...' and 'I think he's having a heart attack' are far more useful phrases. My A Level in Spanish taught me all about the Spanish dictatorship and racism in Spain but with my B grade I couldn't tell the pharmacist I had a mouth ulcer when I went on holiday to Spain a couple of months later. I just kept saying 'duele' and 'boca' and pointing at my mouth. I don't think she understood. What I bought did absolutely nothing.
I was disappointed when my friend who did Latin at school said they just translated old texts. I'd hoped kids were learning how to ask for a lemonade and chips in a dead language.
