The article mentions screens as you'd expect, but it also mentions school's focus on reading short "informational texts" like the sort you'd see on a exam that tests reading comprehension. I think that's the main problem. There's no way around it: to be able to read books you have to get practice reading books. You have to be able to distinguish between the barren sections that you can go over a bit quicker and the fruitful sections you might need to reread. Above all to read actively.
