I've noticed a lot of people lately who are trying to learn a language from the net alone. Through my own experiences with trying to learn languages from the net(whether starting from beginning level or trying to find supplements), I've found that there are usually very few serious resources. There might be a phrasebook site or two, or maybe a site with a short intro. There are also sites that seem to hold a good amount of information, but are more of a "grab bag" of language learning resources, rather than a structured course. However, I think that the net holds great potential for people willing to learn. If one were to create a site structured around a good textbook, with interactive exercises and so on, would a person be able to learn the language as well, or better, as if he had bought the textbook and read it by himself? Although I am in no position to teach Russian(or any other language, including my own), I would be interested in creating a site of this sort with the assistance of native speakers and people experienced in teaching the language. What are your opinions on this matter? Does anyone know of any sites like what I am describing, free or otherwise?
Here are some of my criteria for a site like this:
Structured, well-explained lessons
Exercises that show you where you went wrong and how to do it right
A lively discussion forum, much like this one
The above does not sound that hard to implement. If it were possible, however, I would also like to add this:
Listening exercises, sometimes with videos
Conversation practice, either with real people or a program(through text)
More interactive exercise stuff - for example, writing compositions and having a computer grammar checker(or even a real person) go through it for you
There's also another idea I've got up my sleeve that's a great bit different from the standard ones above, but I will have to ruminate on it a bit.
