Google educational materials
As I loitered in our systems manager's office, I noticed he had a great Google poster up on the wall:
It's kinda old, but the tips still work! I did some googling when I had a minute to find out if they offered that posters for downloads, and lo and behold, there's a whole trove of educational material from Google. Their 'lesson plan search' page has a handful of posters like the one above.
However, it seems like a lot of that information is pretty outdated. You can tell both by the logo and by the text itself. I updated one of the posters by pasting in new screenshots and adding a paragraph to tip #4:
The PDF (2 MB) prints out to 17x22 inches.
I'm hoping they'll update their educational collection, but in the meantime, I might go ahead and revise/recreate some of the other useful posters.
