It would get social interaction...the ability to learn to read and write, and possibly other things --- maybe teach it mathematics, showing it how area and perimeter and whatnot would differ. Just keep it totally blind to the reality of a world outside, and avoid telling it anything religious, philosophical, or about the outside world. Pretty hard, but I'm certain you'd be able to create some curriculum to make it somewhat human as far as you can label it, and it was educated somewhat. Without any influence from the media or anything, or any slightly religious upbringing.
