Screens are *still* worse than Paper for reading retention

My first published academic paper in 1987 explained an elegant experiment I ran using SAT test questions that measure retention to discover if humans retain and understand information better by reading on paper or reading from screens.  Of course the overwhelming measurements and evidence indicate that reading from paper is much better than screens.  Recently, Amy Tyson published an in-depth study about the use of books and paper versus devices (phones, tablets, computers) in classrooms and looking at test scores.  She validated my measurements in school settings.  If you have a kid in school, get them to use books and printed materials.
