  • Magic lantern projector

    Educational practices have benefited from advances in technology for most of human history, often providing spaces and conditions for innovative leaps in science. Here are some of the technologies used to advance education in the past.

    Magic lanterns were the first image projectors used in education, allowing teachers to display large images to entire classrooms.

  • Stereoscope

    Stereoscopes were initially used to provide 3D images of Civil War battle scenes, but became useful in classrooms for historical purposes. The technology uses right and left eye photos to create a three-dimensional image.

  • Mimeograph

    The mimeograph was the precursor to photocopiers, allowing users to make copies of documents using a stencil.

  • Linear slide rule

    Slide rules were created in the 1600s but only became widely used in education by the end of the 1800s and early 1900s. They were originally used for construction, but were eventually produced for consumer and educational use by 1870.

  • Skinner teaching machine

    The creation of the Skinner Teaching Machine in 1954 coincided with a spike in desire for better schooling practices. B. F. Skinner created the machine to give students on-demand math problems, and it could churn out dozens of math equations.

  • The Plato Computer

    Created in 1960, the Plato (Programmed Logic for Automatic Teaching Operations) system was one of the first computer assisted instruction systems and is seen as a precursor to modern computers due to its pioneering of the multi-user computing experience. Scientists credit Plato for establishing screen sharing, e-mail, message boards, multiplayer games and more.

  • Handheld Graphing Calculator

    Starting in 1965 and continuing through the 1970s and 1980s, handheld graphing calculators were created by Japanese company Casio Computer. The products took a massive leap forward in 1985 with the fx-7000G graphing calculator, which quickly became popular in Ohio and subsequently the rest of the US.
