Digital textbooks are changing the way many students learn. All the Fairfax County Public Schools have begun using online course material for their middle- and high-school students. This school year, the schools changed from books to digital textbooks for social studies in its middle and high schools. The change came after digital books were used in 15 schools last year. "Our students come to us technologically ready to use resources from a variety of different places, " says Assistant Superintendent Peter Noonan. "The world is changing consistently. The online textbooks can change right along with the events that are happening." There’s an important financial benefit as well. "Usually it is between $50 and $70 to buy a textbook for each student, " Noonan says, "which adds up to roughly $8 million for all of our students. We actually have bought all of the online textbooks for our students for just under $6 million."
