Mobilizing Minds: Teaching Math and Science in the Age of Sputnik

Geometry Teaching on Closed-Circuit Television, about 1960 and Televised Teaching of Biology, 1965

Television became common in the United States during the 1950s. By the middle of the decade, a few school districts were exploring the use of closed-circuit television, both to provide students materials they could not see otherwise and to reduce costs.

Private companies went on to develop somewhat less expensive closed circuit television systems for the schools. The Philco Corporation adapted the system it had developed for industrial security for use in geometry teaching. Diamond Electronics suggested televised biology teaching. Entire public television stations, such as WETA in Washington, D.C., had their origins in science teaching.
