First of all, I get all my news off the internet. If I had to go a whole day without using the internet, I would have no idea what is going on in the world.
It wouldn't be much different than it was for me as a high school student. I typed all my papers way back in the stone ages on typewriters with carbon paper...can you believe that? I graduated in 1986. It wasn't THAT long ago.
Of course, last week, we had three days with no access to the internet because of a virus protection company scare. The local TV station actually came out to do a story about how we had to revert to "old school" teaching methods. Ha! So, yes, we used the whiteboards more, the old fashioned overhead projectors, and more paper hands-on manipulatives than the interactive smartboards, but we got through it with very few scars.
My students marvel how I don't carry a cell phone. I refuse to do it. I like not being hounded by something beeping at me or ringing 24/7. Call me old-fashioned, but it's more difficult to stop and smell the roses and enjoy the daily blessings around us when we are so distracted with the most up-to-date Ipad, Iphone, or some other gadget.
