here you go fedi.

@kirakira I was in the really special math class. We had the LCD display that goes on top of that thing that shows a ti graphing calculator screen on the projection.

At my university (I study computer engineering, other students might have a different experience) it is mostly either computers (PowerPoint/LaTeX Beamer slides; usually for most computer science stuff) or blackboard only (math stuff).

The course using these things still was about models for information processing in the brain and mostly used backboard with a few dias shown containing graphs, complex sketches, pictures, etc. presented using the overhead projector.

I personally enjoy courses mostly done with blackboard, because it typically limits the professor's talking speed to their writing speed and also allows me to write almost everything down.
I've had a course using 180+ slides for each 90-minute lecture. Not even those "I made an animation by making thing appear slide-by-slide", no, it was 180 slides of mostly new content. No chance to write anything down or even fully grasp one slide before the next one is shown…

@TheMNWolf yes! They stated pulling that out in my 8th grade algebra class and I thought it was the coolest thing in the world. Always wondered how well it would display the games all the students had on their calculators

@kirakira You knew you were in for a shit lesson when you saw one of these bastards rolled out.

@kirakira The refresh-rate and the input-responsiveness on that thing are NUTS.

@dicenbuttons @jcm @kirakira

It's all computers... My kid is in elementary school and they've got a digital projector or a giant LCD touch screen on the wall in every room.

I think I've seen the overhead projectors mostly relegated to the corner of the room with a stack of unused binders on top.

(I graduated HS in 2006 and remember taking so many notes in HS and college from lectures given by someone hunched over one of these.)

I think you may be projecting, @kirakira.

[pauamma@mstdn.social]

@kirakira i used those. Once underlined something in red-tip on the displayed slide for effect, earning me stunned respect. Someone said "I didn't know that was possible."

[joshua@hooray.computer]

@kirakira hell yeah

[dicenbuttons@mastodon.social]

@IrrationalMethod @jcm @kirakira

I guess I'm old now. "Back in my day..."

Preface aside, it seems to me that a giant TV screen is a miserable way to teach kids. Sigh.

@kirakira oh!! thats my Friend from grade school!!

[krishean@tech.lgbt]

@kirakira definitely a technology of all time

@deersyrup @kirakira
You just need a laser printer (and a microfiche if you don't have much clear plastic)

[futurebird@sauropods.win]

@kirakira

Listen we don't LIKE technology around these part anymore, missy.

[mxchara@cyberpunk.lol]

@kirakira I miss these. expert mode: if there's a scroll of acetate sheet going across the platform so the lecturer can write out notes continuously, scrolling the plastic to get a clear writing area

[zackwhittaker@mastodon.social]

@kirakira this took me right back to my childhood school days back in england, thank you for sparking this memory.

[chu@climatejustice.social]

@kirakira

There's a sad short circuit look about that fellow.

@kirakira
I don't have a reason to draw on a map or an outline a lot BUT I could do some heckin lineart scaleups for large scale graphics, with the comfortable cumberance of analogue.

Wut? Cool wall-sized paintings et all.
It could be done a lot of ways but ALSO sometimes tool is stimmy.

@kirakira

This reminds me of the big diapositive slides we had at the university, changing them in the dual slide projector was my first student job.
