I understand what you mean: Interactive learning is nothing like learning from a textbook or Rosetta Stone. I hired a French conversation tutor to talk with once a week over the phone by placing an ad on Craigslist. In my town, a family that owns a Japanese restaurant also give group lessons if there are enough students. Some big cities have cultural groups like Japan Society, but if you live in a small town maybe you can post an ad explaining that you want to start a conversation circle for young teens, or hire a native speaker for lessons. If you don't want to post on Craigslist, perhaps you could try church bulletins, local newspapers, or a community college newspaper.
Try Rosetta Stone. Used it to learn basic Mandarin, it's quite good. Also check out the local community college, a lot will allow HS students to take classes and many High Schools will give you course credit towards your diploma. <br />
Hint on Rosetta Stone. It comes with a money back guarantee in case she doesn't like it or gets bored with it quickly
For the most part listening and speaking only.
