How overhead projectors took over your classroom
It used to be so easy to get away with things in school. The teacher, after all, was always turned around writing at the chalkboard! But then came a bit of technology, previously mostly used for military purposes, called the overhead projector. It would change far more than just the disciplinary record of students everywhere. […]
In this episode of Version History, David Pierce, Jake Kastrenakes, and Stanford professor Antero Garcia explore the rise, impact, and decline of the overhead projector in classrooms. This technology, initially used for military purposes, revolutionized the way students learned and the discipline records of educators. Kastrenakes notes that overhead projectors transformed the educational landscape, while Garcia highlights their significant influence on learning methods.
Despite their eventual disappearance, the episode questions whether modern alternatives, such as PowerPoint presentations, computer screens, and smart boards, genuinely surpassed the capabilities of the overhead projector (OHP). This marks the final installment of the fifth season of Version History, which has covered various iconic school technologies, including the Oregon Trail game, the original Chromebook, the One Laptop Per Child program, LeapFrog LeapPad, and TI calculators.
For those interested in learning more about the OHP, the episode provides links to resources like a history of the Magic Lantern, 3M's century of innovation, an OHP advertisement, and an NPR article on Sputnik's impact on U.S. science education.
