“The Educator” sounds a bit ominous. Sounds like it’s for some kind of a weapon.

I remember seeing one of those for the first time in like 3rd grade, and I spent the whole class thinking about how the hell out worked. I'm almost 40 now, and it still puzzles me.

Are overheard projectors still in common use or can I post a picture to /r/nostalgia?

I remember growing up and my mother had a wood paddle that said “Educator” in it.

You forgot to put in the zeroes.

Probably the name of the paddle wielded by any American high school vice principal. Though our VP's paddle was named Bertha.

It also sounds like a movie starring either Liam Neeson or Denzel Washington.

In Germany, sadly yes.

The digitisation of school is moving forward at a snails pace. 5th largest economy on the planet, bruh.

Awfully close to "The Substitute" starring Tom Berenger.

Probably for the best. I'm in Canada and a bunch of schools around me have smart boards. They really aren't any more effecting than a black board and cost a lot of money.

Isn't the solar panel facing the wrong way? :D

Sad, but I imagine a lot of kids these days, might not know what an overhead projector is.

The bottom part is just a touch screen. The LCD display is just that, an LCD display. They're naturally transparent. Your standard calculator has a mirror behind the display so it appears opaque. And LCD computer screens have a lamp behind them to make them work in the dark and not depend on an external light source. The displays have liquid crystals sandwiched between two glass panes. Sending a current through the panes will align the crystals, and in combination with a polarizer foil, block the light. In other words, the black "ink" you see is not actually ink, but the absence of light, or a shadow.

If this one fails they will break out "The "Driller"

I wanna know what happens when you press the "SIMP" button

If your school district was like mine, they upgraded to smart boards but didn't bother giving any of the teachers lessons on how to use it. So it's not used at all in like 80 percent of the classes.
