gabsid I teach English in Spain (I'm British) so I see it as a bit of a responsibility to speak to the English learners in English; it's not really helping with my Spanish!!!
I see language learning as something quite important. When I came to Spain, I couldn't speak Spanish and it was a major problem for me. I couldn't go anywhere without my partner incase I had to speak to someone.
For personal growth I think it is incredible, but this is not always a priority with people and with the push for English in Europe this makes it even less of a priority. A uni student told me that many companies were not interested in interviewing candidates if they did not have a basic level of English. Also, I have seen a huge difference in the last 5 years with the level and the amount of people learning English.
What I see as a problem is that although the government is planning on making many changes with languages on the curriculum and pushing to make it a subject that people will take more seriously, only a small percentage will learn a language properly from the classroom alone. There is a lot of pressure on language teachers, but from what I have seen here the people that tend to have a good level of English normally have extra classes.
I believe the topic of language learning has to be looked at from a completely new perspective and be 'marketed' not simply as another school subject, but something that can offer much more than improved job prospects, otherwise the lost opportunities that I experienced at school, along with many others, will only be repeated.
Sorry the reply is a bit long, this is a subject close to my heart.
