This doesn't really seem to hold much water. For one, the study was done on college undergrads, a non-randomly selected group who have crossed a certain bar for basic comprehension (looks like the researchers are from the U of Maryland, a major university, so you can expect that the students on average will have well above-average reading comprehension compared to the rest of the world). On top of that, as a former K12 educator, the tools matter far less than the teacher implementing them and the fidelity of execution, very little of which seems to be explored by this study. I don't think digital texts or computers in classrooms are a panacea for what ails our classrooms or that digitizing textbooks is even that exciting when it comes to EdTech -- it's just taking a 19th century tool and digitizing it. This study, however, does not effectively demonstrate that either medium is better than the other, but the Ed world is in desperate need of strong research in that regard, specifically in the efficacy of EdTech in the classroom.
