“Which teacher has time to make custom books for his or her class? One of the things I’ve become concerned about is the number of items we tend to keep adding to a teacher’s plate. They have to manage a classroom of 15-30 kids, understand all of the material they teach, learn all of the systems their school uses, handle discipline issues, grade papers, and help students learn.”
“When do we start to take things off of a teacher’s plates? When do we give them more hours in the day? Whatever Apple envisioned in 2012, it’s clear that did not play out.”
