A common concern for most teachers is that students are reading less and less each year. With all the electronics that sap a child's time, sometimes I wonder why they read books at all. Just joking, but only kind of.
Now, over at tor.com, they have looked into the literacy rates in the most famous republic in a galaxy far, far away. What they found, may be shocking. The republic is a post-literacy world. Everything is recording in video/hologram form, and most things have an icon or picture showing what they do. I'd recommend reading that article, particularly if you are someone who appreciates the holy trilogy.
What I find interesting about it is how the lack of literacy causes a lack of ability for the general populace to defend against tyranny, according to the article. While we might feel that we need to share with our students some level of media awareness, perhaps the greatest reason to support literacy is that a illiterate society can be controlled much easier.
