Write all your computer programs with node, and then convince your professor why writing with node is superior to the java server he assigned ;) And then pray he doesn't give you an F!
Part of the evangelism is simply just doing stuff with the language in projects, and talking to people about the benefits of it. In the academic world, you're in a prime location to do this! I've noticed that a lot of schools are not quite on the edge of technology (it's really quite hard for a school to do that, so don't bash them too hard), and it takes students making presentations and giving talking points about the advantages of a language to make things move. Try talking to your professor or academic advisor about adding courses with Node. Many professors are willing to help students learn something new (it is why they teach, isn't it?), but sometimes it takes a push, and sometimes many pushes :)
Learn all that you can, and then maybe offer to lead a class/seminar about how to accomplish something with Node. Talk to the CS Department Head and see if you can't get an event started about using Node. A good idea would be a coding challenge event (offer pizza, it's a sure fire way to get attendance) with using specific tools (such as Node). If your school has a local ACM chapter, see if they'd be willing to sponsor it.
