I remember "The Reading Lesson" by Stephen L Burns, published in Analog Science Fiction and Fact, in which there was a difference in the manner of reading. Some people read and retained, appreciating the word, and others were basically "Barking at Print," saying the words without any true internalisation or understanding.
I see that today with some young people, allegedly able to read, functionally "literate," but listening to them read out loud they are "barking at print," and when quizzed have no understanding of what they have just read.
It's not new, but it makes me wonder how we can help people to learn to read better.
The same goes to a greater or lesser extent for math.
