Teacher here.
My favourite “lesson” I ever gave was in a grade 9 technology class. It was a pretty small class, about 10 kids. I split them up into two teams and made a competition. They chose their own teams — it ended up being boys vs girls. I never would have made it that way on my own but that’s how it worked out.
The school had a bunch of old, decommissioned PCs that were headed to the junk yard. I sorted through all of them to get two exact sets of working parts for the competition.
The goal of the competition was to recover a jpeg from one of the hard drives. Each team had a computer with the ram removed and two hard drives. One was blank and the other had the jpeg on it. They also had a Linux Mint installer on a usb stick.
I don’t remember exactly how I had set it up but it was points based, something about getting to different stages first. Like 5 points to be the team that turns the computer on first. One of the big ones was that they got an extra 10 points if they did the whole thing without a mouse.
I told the other classes about the competition and asked some other teachers if it would be okay for them to watch and cheer on. It ended up being the nerdiest and most exciting class ever. Students were literally cheering each team through a Linux install. One team got stuck and had to pull out the mouse. There was booing. It was so epic.
The girls won, being the first to recover the jpeg and they did it all without a mouse. It was so awesome. The jpeg was the meme about how would a dog wear pants.
It was about 5 years ago, my first year teaching. I really miss those days. I only teach math now, and while I like that, there was something magical about showing kids how fun computers can be.
