I found this podcast from this 
post:
I subbed today for a 7th and 8th grade teacher. I’m not exaggerating when I say at least 50% of the students were at a 2nd grade reading level. The students were to spend the class time filling out an “all about me” worksheet, what’s your name, favorite color, favorite food etc. I was asked 20 times today “what is this word?”. Movie. Excited. Trait. “How do I spell race car driver?”
I’ve only listened to one episode so far, but it’s really well produced, seems well-researched and very well put together.
From what I gather so far, the ways that the American public school system “teaches” kids how to read is not only completely wrong, but actually saddles them bad habits which fundamentally hinder their reading comprehension.
A huge swath of American adults are functionally illiterate, and I think I’m starting to understand why.
I’ve lived in several blended homes with other parents and they always like to trade off on reading to kids at night. It’s easier when you can take turns. But also there’s a common frustration with the act of reading to a child becoming boring after a while. And I think a lot of it has to do with fluency. I’ve heard many grown adults struggle to read books meant to children. It’s not that they couldn’t read the words. It’s that they were so busy reading off the page that they couldn’t control their inflection, add drama, or discuss the contents of the story while reading. It’s kind of like watching someone whoMs really good at the piano sight read music they’re not familiar with for the first time. You can hear the song come out, but it’s stunted and awkward and not very expressive.
It’s hard if they don’t realise storytelling is a performing art and you’re communicating the book to the child, not to yourself, so you have to send the images in your head to the child.
