Having computers with large projectors absolutely changes how you can teach classes. In the past, I would need to struggle to make copies and waste tons of paper recreating most of the things I put on a white board for the students. Now I can just put something interactive on the board and show them how it works. I can also search and find up to date information on any safe for work topic the students might inquire.
In my first class today, the students were learning about money. I went to the Wikipedia entry for American currency and showed them the pictures of all the different currency. My Korean co-teacher was printing, laminating, and copying tactile money for them to interact with, but I introduced them to all the bills before she ever came in the room. I could also look up the exchange rate (ouch!) and tell the students the approximate value of each bit of currency in Korean won so they’d understand the relative value of each.
In another class I was teaching about Egyptian mummies. We got to explore a virtual “tomb”, which was one of their vocabulary words for the day. I also got to show them the mummy’s elaborate protection against weather and corrosion in their coffins. Then we even got to explore the forensics of how they made a mummy. Pictures of mummies and everything else turns the topic into something much more interesting than what the book presented.
In my last class, we were talking about “life on the prairie”. After reviewing the topic yet again, I fired up a game of Oregon Trail. I explained, “This game was old when I was your age, but it’s still awesome. We’re going to see which of your classmates survives on the Oregon Trail!” Students watched with morbid fascination as our oxen pulled the wagon across the trail. We set the pace to gruesome when class was winding down to add more casualties. Measles, typhoid, dysentery, and lots of food shortages were par for the course. Three students died, and we had to stop while floating down the big river at the end of the game. The students thought Oregon Trail was awesome. They told the Korean co-teacher it was SO much fun to watch their classmates die. Hah.
Anyway, all my classes have changed because of the projectors in one way or another. I’d be hardpressed to go back to the old “draw everything and copy the rest” way if I had to in the future. Students love the interactive nature of the Internet, and while I have added responsibilty to make sure everything is suitable for them, I think it’s augmented my teaching and expanded my flexibility as a teacher too.
