How overhead projectors took over your classroom
An episode of the Version History podcast explores how overhead projectors moved from mainly military use into classrooms, changing how teachers presented information and how pupils learned. It also asks why the devices largely disappeared and whether tools such as PowerPoint, computer screens and interactive whiteboards improved on them.
Hosted by David Pierce, the episode features Verge journalist Jake Kastrenakes and Stanford professor Antero Garcia. It is the fifth season’s final instalment, following episodes about school technologies including Oregon Trail, the original Chromebook, the One Laptop Per Child programme, LeapFrog LeapPad and Texas Instruments calculators.
