M: Our school is replacing printed textbooks with e-textbooks next semester. I can’t wait.
W: Really? What about the cost, not only buying all those tablets, but the software and electronic infrastructure that goes with it, not to mention retraining all the teachers and administration staff?
M: Sure, the initial expenditure will be high, but much lower afterwards. Besides that, tablet prices continue to drop and are becoming increasingly affordable. Anyway, tablets help students learn up to 80% faster.

W: Not necessarily. Tablets have too many distractions. Students may pay attention to apps, games and websites instead of their teachers. In fact, research suggests that people who read printed text comprehend more, remember more and learn 30% more than those who read digital text.
M: Yes. But tablets contain many technological features that are not found in printed textbooks. Think about it. Students are able to highlight and edit text, write notes and search for information much more quickly than they can with printed textbooks. And what about all those trees that are cut down to make printed books?

W: Actually, manufacturing tablets is environmentally destructive and dangerous to human health. The health impacts from making one electronic reader are 70 times greater than those from making a single printed book. A lot of minerals are extracted from the earth to make electronic readers. It does far more damage to the environment.
M: Yes. But the software for electronic readers can be updated instantly without the need for buying a whole lot of new books. That’s better for the environment.
W: But the core curriculum doesn’t change that much. Printed textbooks that are not brand new, still contain the basic relevant information of core subjects.
M: Well, I’m looking forward to the change.
W: I’ll stick with my printed books.
