Learning is all very personal, isn't it? So many people, including many otherwise enlightened ones, still believe that there is one way to teach, and one way to learn, that everyone can learn everything...
What use is the teaching of languages and music in schools? What is the point in Maths learning? Calculators, tills, petrol pumps, satnavs, computers, they all do the work for you. Okay, if you really like maths and want to become an engineer or something then you could just learn it at home from your parents or a tutor, because the vast majority of students will grow up to never need or use it, and the vast majority of adults are useless at it anyway. In Spain they can offer change in a second language, but here cashiers can't even figure it out in English! There must be something wrong with the way we teach maths in this country. What a waste of time!
Don't even get me started on English Language or Literature, History, Geography. What about PE??!! What do they learn there? A third of 11 year olds are overweight or obese!
I don't know anything about teaching. I know a fair bit about my own learning, and I enjoyed music and languages at school. I do know that if I didn't enjoy something, I pretty much couldn't learn it. Really, what was the point in Latin?? I came out of school not speaking any second language, but nowadays I can order dinner and do my shopping in French, find directions, and generally get by. I have listened to language courses, but if I hadn't learned shopping lists in school I'd be lost for hours looking for things in the Hypermarkets. So there was some benefit to the method, if not immediately.
The difference has been mentioned, it's getting to actually speak. I learned to speak another language starting after university, and am now fluent. Bilingual. In adulthood. Because I had to speak that language, barriers came down in my head, and suddenly using schoolboy French wasn't anything to worry about.
My children are bilingual from toddling. Their vocabulary is not as complete but their pronunciation is much better, accented naturally. They both went to school in Wales, and started learning Welsh in primary from four or five years old, but in an English medium. They're still learning Welsh, they know some - they're both secondary now - but they can't speak it at all. French though, well the older started learning that in secondary, and can hold a basic conversation, do shopping, get directions. He's no better at French than many of his peers, but he's much better with French than Welsh. Both of my children dislike Welsh. They can't see the point. (Even as a patriotic Welshman myself I'm beginning to agree...)
I don't believe that being bilingual automatically makes it easier for you to learn other languages. I've met bilinguals who were crap at both languages. But I do believe that if you achieve success in that second language it can overcome barriers to learning others if that is what you are interested in, and that counts for adults as well as children. I also don't believe that adults are worse at learning languages, but I do believe that children are able to mimic without embarassment - a huge advantage for learning orally. If adults did that they would also learn languages very well. Remember, it takes many years to learn your first language, and some people don't even manage that to GCSE standard.
I do believe that the more that you learn the more capable you are of learning. So learning music for the sake of music may not be worthwhile if you are not to become something in the music world, but it may be helping to open your mind to many other subje
