Summary

  • Version History’s latest episode examines how the overhead projector moved from military use into classrooms and reshaped how teachers taught and students learned.
  • David Pierce is joined by Verge editor Jake Kastrenakes and Stanford professor Antero Garcia to trace the device’s development, adoption and educational impact.
  • The episode also asks why overhead projectors largely disappeared and whether replacements such as PowerPoint, computer screens and smart boards actually improved on them.
  • Season 5 ends with the overhead projector after episodes on Oregon Trail, the original Chromebook, One Laptop Per Child, the LeapFrog LeapPad and Texas Instruments calculators.
