Most of these students won't go on to international business, or become interpreters for visiting dignitaries, especially students going to school in a 3rd tier city.
I also seriously doubt they'd have their own international businesses, but they may work for someone elses' (one of my friends here did), and while they wouldn't be interpreters for "visiting dignitaries"
they could work in the tourist industry (a student from my university happened to be a tour guide on a bus I took to the Terracotta Warriors). There sure need to be more English speaking staff in train stations, bus stations, hotels and restaurants, to judge from my traveling experiences in China.
The vast majority of them won't need oral English at all, ever, in their future lives after college.
I don't see it that way. Most my students are English majors, and as such might go into a field in which they need to speak English, even if it's just working in a training school or a public school where there are foreigners. If they become English teachers – and I think that's the best job available to most of them – they'll need to speak, and the more they've learned from their foreign teacher (assuming he/she is any good) the better.
A small percentage of them may need it occasionally when, say, a foreign client visits from overseas (but they'll be able to scrape by just fine on what they learned in college regardless of whether they did well in Oral English or not) or if they decide to persue graduate studies abroad (at which point they'll have to start from scratch with some serious prep courses anyhow), but most of them will work in Chinese companies, will rarely come into contact with foreigners, certainly won't have any foreign friends, and will never ever travel, much less live abroad. That's just the plain facts of life for most Chinese people and since you're teaching what seems to be your average Chinese class it is fair to assume their futures will be pretty average.
The picture you paint is a bit gray, even Kafkaesque, though admittedly so is what I see when I look out the window. If the world stays exactly as it is that may well be their futures, but many are perfectly capable of having foreign friends, working in international companies… and only finances limit them from traveling or living/working abroad. The world may change dramatically for them. When I look around at all the new cement buildings and mega-highways I think it's strange that they are building solidly for a future that is already an anachronism. Who knows what role technology, global warming, and untold other variables will have, what doors they will open and by what means? It seems likely there will be more leisure time in the future, and more opportunities both to travel and to communicate with people from other countries via the internet and other technology.
As the world changes I'm guessing the ability to speak English may be the difference between being sequestered in a China of the past and reaching out to the rest of the world via the international language. At very least students with solid speaking/listening skills can more readily partake of foreign culture and expand their horizons through watching movies, TV…
A lot of money and time in China is spent on chasing an English pipe dream and I'm not really all that convinced that, besides the fact that the pipe dream keeps most of us employed, it is really all that productive for all these students to be focusing on fluent oral English rather than some other thing that they might be better at. And yes, English is important for some people, but those people tend to know who they are. Maybe your students are just being realistic?
I think China has made a wise choice there. How expensive is it really? My students spend 2 hours a week for two years working on their Oral English. Any less would be a joke. They are university students, and cultural/global awareness seems entirely relevant to a fundamental university education that isn't just learning a trade.
Most my students are pretty good, and the recent slump has everything to do with countless hours devoted to the insurmountable TEM4 exam, and the enormous amount of homework they have in their other English classes. I have a class for non-English majors that's bursting at the seems, so I gather there are lots of students who want more Oral English [a student told me this optional class filled up within hours of if becoming available]. Are the "realistic" ones the ones who are just too lazy to do much of anything (English majors who can't write or spell, for that matter)?
I'm not sure the problem is the students themselves at all, but rather the circumstances in which they're in while taking my class. They are bombarded with homework and exam prep from elsewhere and burnt out from it, and perhaps other teachers are telling that their classes are the important ones.
As for taking your class seriously, I would just use good old grades. They can't graduate if they fail your class, right? So fail them. No doubt they'll come grovelling to you and the school will make noises about having to give them a retest or some such, but word will get around that your class is important and that you take the grading of it seriously, regardless of whether or not English itself is actually important to them.
Probably a good idea. There are only two failing, and just by enough that if they do some extra credit they can pass. If they don't do it, yeah, I'll fail them for sure.
