"You Were There" and the Standard School Broadcasts. We would listen to these radio programs during class as part of our usual schedule. And dittos. The worst was having to MAKE the dittos. You had to know what you were doing to run the thing. Make sure the ink tank was full, and fill it if needed. Turn the tank upside down and make sure the felt was covered with ink. Then crank, and count the cranks. Then you had purple fingers all day (the ink was clear, but turned purple on the paper or your skin). The film strip projector was my favorite. Sometimes the teacher would let a student turn to the next picture, but you had to do it right when the "ding" sounded on the cassett tape, which provided the sound. I retired from teaching 3 years ago (I did my 38 years--time to go). I was still using filmstrips for my music classes. The students loved them because the pictures didn't move, and I could make the pictures big enough for the whole room to see. I could stop and discuss the material at any time, unlike a video. I still have a film strip projector, but you can't buy filmstrips anymore. In college, I actually had to take--and pass-- a class on "technology". That included showing I could run the ditto machine, the copy machine, film strip projector, and the reel-to-reel movie projector. Both kinds of reel-to-reel. The one that threaded automatically, and the one that you had to thread by hand. We also had to demonstrate how to change the bulbs and do basic repairs on everything (except the copy machine). Those were the days!
