Perhaps if museums for kids were better tailored for interactive education instead of going through and being told to read each sign and label students would care. Maybe times have changed and that's how it generally is today, I hope that's true.
You obviously haven't been in a museum in the last couple of decades. They have had interactive displays, personal spoken tours using portable audio devices (using an MP3 player, Discman or Minidisc player), and the better museums had tour guides. That is the new technology where a person takes a group of people around and tells them about the art. It's amazing what they can do these days!
But maybe if you are the kind of person who cannot read a small sign, then perhaps even a museum couldn't be much help for you. I wonder how you go with some of those lengthy dissertations on Twitter.
