18 Classroom Gadgets That Disappeared

Schools once relied on a wide variety of gadgets that defined classroom life. However, technology has since replaced them. Some were useful and many now feel like relics from another era. Here are 18 classroom gadgets that disappeared and live on only in our memories.

1. 1. Overhead Projectors

Every classroom had one of these bulky machines perched on a cart, its light bulb humming while the teacher wrote notes on a transparent sheet. The squeaky sound of markers on plastic filled the room, and the smell of permanent ink hung in the air.

2. 2. Filmstrip Projectors

The rhythmic click and occasional beep of a filmstrip projector were the soundtrack of many classrooms. Teachers loved using them for quick visual lessons, even though the film often jammed or melted under the light. Students would eagerly wait for the next slide to advance, half paying attention and half daydreaming.

3. 3. Slide Projectors

Loading circular trays of slides into these machines felt like preparing for a mini movie premiere. Teachers had to handle each slide carefully to avoid fingerprints, and the entire presentation could grind to a halt if one jammed.

4. 4. Ditto Machines

Before photocopiers took over, teachers relied on the ditto machine, a messy but beloved piece of equipment. It produced worksheets drenched in purple ink that smelled unmistakably chemical. Freshly printed pages were damp, and kids couldn’t resist sniffing them before the scent faded.

5. 5. Chalkboard Compasses

These giant, metal tools were once a geometry teacher’s best friend. They drew perfect circles on chalkboards; when they didn’t screech across the surface or snap in half mid-draw. Students would groan at the ear-piercing sound, and clouds of chalk dust filled the air.

6. 6. Overhead Transparencies

Teachers used these clear sheets to scrawl notes, diagrams, or equations under the glow of a projector bulb. One smudge of a finger could ruin the entire presentation, and by the end of the year, the once-clear sheets were a rainbow of dry-erase stains.

7. 7. Pencil Sharpeners Bolted to the Wall

Every classroom had one: loud, metal, and mounted right by the door. The grinding noise was a constant interruption, and kids would often break their pencils on purpose just to use the sharpener. Sharpening became a social event, with long lines forming during math lessons.

8. 8. Floppy Disks

Once considered high-tech, these flimsy plastic squares could barely hold a single paper. They bent easily, corrupted files without warning, and often left students heartbroken when their essays wouldn’t open. Yet, for a time, they were the symbol of progress in computer labs across the country.

9. 9. Film Projectors with Reels

Teachers had to thread the film carefully through spinning reels, hoping it wouldn’t tangle or snap. Watching movies in class felt like a treat, until the film broke halfway through or burned under the heat of the bulb. The whirring sound and occasional flicker of the image made every viewing unpredictable.

10. 10. Chalkboard Erasers

These felt-covered blocks were simple but essential tools in every classroom. Teachers would bang them together outside to clean them, sending clouds of chalk dust into the air while students coughed and laughed.

11. 11. Record Players in Classrooms

Before digital audio, teachers played vinyl records during lessons; especially for music appreciation or language learning. The soft crackle of the needle was part of the experience, even when the record skipped or scratched.

12. 12. Filmstrip Cassette Combos

These quirky gadgets paired visual slides with audio narration on a cassette tape. Every few seconds, a loud “beep” signaled the teacher to advance the filmstrip manually. The timing was rarely perfect, but students didn’t mind; it beat another hour of math problems.

13. 13. Overhead Projector Bulb Warmers

Teachers who forgot to turn off the projector often turned their classrooms into mini saunas. Sitting near one of these glowing boxes meant sweating through your shirt during afternoon classes. The bulb’s hum was oddly comforting, even if it doubled as a heater.

14. 14. Laminators in the Back Room

Every teacher had a love-hate relationship with the school laminator. It took forever to warm up, smelled like melted plastic, and jammed more often than it worked. Still, the glossy finish it gave to classroom posters made all the effort worthwhile.

15. 15. Typewriters in Computer Labs

Even after computers arrived, some schools kept old typewriters in the back for “practice.” The rhythmic clack of the keys echoed through the room, and fixing mistakes meant battling with correction tape. Students who grew up in the digital age couldn’t believe how slow and loud they were.

16. 16. Slide Rule Rulers

Before calculators, students had to master the art of using slide rules to perform complex math. They looked simple but required precision, patience, and a sharp mind to use correctly. Teachers spent weeks showing students how to align the scales just right.

17. 17. TV on a Rolling Cart

Nothing brought excitement to a classroom like seeing the TV cart roll in. It usually meant movie day or at least a documentary that gave everyone a break from note-taking. The heavy set was strapped down to the cart, wobbling dangerously every time it moved.

18. 18. Transparency Markers

These colorful markers were the lifeblood of every overhead projector lesson. Teachers went through them fast, often forgetting to put the caps back on, which left them dried out by midweek. They stained hands, sleeves, and sometimes desks, leaving behind rainbow smudges.
