I have an affinity for vintage educational films, and this one is a treasure. Recorded in “filmstrip” style, this was probably originally presented with a slide projector and tape recorder (complete with the “beep” sound to prompt you to change slides) and then converted to video.
In this short film produced by the FDA, the disembodied voice of the narrator keeps telling a father what he’s doing wrong while he prepares food for his family.
The review at the end was helpful, and they used the same language to iterate the points, which helps with retention. I even learned one or two things I could improve on. I’m just glad I learned them this way, and not by having an uninvited disembodied voice criticize my food preparation skills.
