I'm just going to butt in here- my step brother (just finished 6th grade) told me that he has a typing class, where the teacher (of 25 years) was adamant about never using the backspace key. I found this alarming, because it means she was still teaching typewriter technique. We have a backspace for a reason: to delete for mistakes.
Along the same lines, calculators are forbidden in the classroom, because you will not be able to use them in the real world. Trust me, my employer would much rather me use a calculator than pencil and paper. It's faster, and more accurate.
Absolutely NO use of phones or electronic devices. I use my phone as a tool for effective communication constantly at work. And yes, I text my friends/family, and no, my boss doesn't care. He does it too.
No wikipedia. If I need to learn about something, guess where I go to read about it?
Learn theory in school. At work, I learn applications, and my company's methods (which are nowhere close to what I learned in school.)
I have a few complaints about the 16 years I spent in school. I graduated college two years ago, and I have barely used any of the information I learned there. Of all the information pumped into my head, I'm going to estimate I've used 2.5%.
No more.
Typing teachers still teach not to use the backspace because of autocorrect. Most people will type faster if they go back and correct the errors at the end. Many errors will be fixed by the autocorrect.
Students need to know how to do math without a calculator. Knowing your multiplication tables is the foundation for many other things in mathematics.
