Here's TV in the classroom 1962. My 6th grade class. TV was a "Ling DeLuxe Television" built by Ling Electronics here locally. They outfitted the main high school in the district with a small studio setup and transmitter that was on UHF ch 23. Each school had a parabolic dish UHF antenna. Each classroom had a kid appointed to be the one who pushed the TVs from one room to another, as the TVs were shared. At least once someone got going too fast and toppled one over in the hallway. I remember getting Spanish lessons and some history lessons on those TVs.
Good ol' Mr. Duncan standing beside the TV.
(Yes I am in the picture. No I won't say which one!)
