However, some students who do have a background in a language can sometimes be the worst to teach. They can be complacent and feel that they don't really need to try learning the formalities of a language. They might be very good in conversation, but as far as I've heard, that's not really good enough at VCE level. These students probably aren't quite fluent, though.
That's a good point, as VCE LOTE doesn't assess informal general conversation skills, but formal language in responses that are basically half memorised. However, having a background in a language enables people to be very quick with responses, without a need to think too hard about what they're saying.
Of course, this doesn't help with writing/reading...Even though I speak Vietnamese at home, I know I would get completely destroyed on VCE Vietnamese if I attempted it. I understand Japanese grammar/mechanics and can write better than I can in Vietnamese, but when speaking Japanese I have to think and as a result am not as fluent. But I was one of the worst in my class at Vietnamese school before I quit. Students who have a background AND are taught the technicalities of their language are certainly poised to do well.
There are other countries in Europe and Asia where being bilingual (native language and English) is quite normal, and there are many who are trilingual. When I went to Malaysia, my taxi driver said his son was learning four languages, Mandarin, an Indian language, English and Malaysian. This was because he was of Indian origin, going to a Chinese school where Mandarin, English, and of course Malaysian was taught. And Malaysians have very good English.
Australia has a long way to go in LOTE education...
