Part of the point of reading literature is appreciating how authors write books. "Literacy" includes being able to read and understand diverse styles of writing. This seems more like it's geared toward passing standardized tests that require reading comprehension.

How does that help teen literacy?

We shouldn’t be pushing great literature on teens. They lack the life experience to even appreciate it. They mark it down as “read” and then it’s off their list for life. All we do by pushing crap teenagers don’t get and therefore don’t like on teens is to inoculate them from great fiction. Let them read whatever they like.

The timeless stuff doesn’t become apparent as such until one’s thirties anyway.

I hope you're right, because tools like these are going to be used whether we like it or not ha.
