Sixty-seven percent of teachers report using more digital books this year than last, according to a survey of 300 teachers and 100 administrators by OverDrive Education. Of those surveyed, a majority said they were conducting at least some instruction online. This of course, is a sign of the times, but important now more than ever to keep in mind the students that lack access to technology. Among teachers in rural schools, 58% say they don’t use any ebooks in their classes.
