I don’t know about you guys, but I don’t know anyone in my school who carries 30lbs of books in their backpackss. But then again, very few people actually use backpacks between classes. My HS has a Junior High attached to it, and together there are about 2000 students. All my classes are in one half of the school and we have four minute breaks between classes.
Obviously, I don’t need to carry all my books between my classes. However, even when I do need to carry my books for all the subjects (when I go to school and go home, if I have HW in all of the subjects, that is) I can’t imagine a 30lb backpack. I don’t know how big the textbooks you guys are talking about are (are we talking about full-sized dictionaries?), but mine are about 1 1/2" to 2 1/2" and none of them weigh more than 4lbs each. I only have five subjects this year (three this semester and two for the next) and I don’t use my Physics book (which is the heaviest, and thanks to my teacher who prepared all the required notes in one package to put in our binders) and my English books usually consist of just one novel-sized book.
Oh, and my backpack is a medium-sized Janson one, which is ripping at the seams. Hmmm, time to buy a new one, I guess. My backpack never weighs more than 15lbs.
I would think that the problem is not so much in high school, but in junior high. In JH I remember carrying (what seemed to me) a heavy backpack around all day. Solution? I carried the actual texts in my arms.
Regarding having CDs as textbooks, there are several problems:
-
Textbooks are needed in class. Therefore, laptops would be needed in addition to a computer at home. Unless it’s a private school full of rich kids this would never work.
-
Even so, what about charging batteries? The infrastructure of the school would need to be completely revamped and the power bills would be through the roof.
-
Laptops are heavy, and binders would probably still be needed, and therefore it wouldn’t be much lighter. Charging equipment would also be needed. Furthermore, expensive electronics tend to break easily and also tend to get stolen easily.
-
All the textbooks would need to be repurchased, even if it is in CD form. Schools don’t do this often, and the CDs would likely be just a little cheaper than the textbooks. You aren’t paying for the paper so much as you are for the actual content.
-
People usually use textbooks to look up facts/data quickly, and having to boot up every time you want to do that would make things more troublesome.
-
And the typing noise is f’king annoying.
