Ray, Joseph J.
Description
For his teaching machine (known to him as the multitester), Joseph Ray used long strips of cardboard with twenty pairs of words or pairs of images written or drawn on one side. Occasionally there also were pairs of words or pairs of images on the other side. Ray called these tapes. This tape is simply divided into twenty sections with pencil lines – it has no words or drawings. It could serve as a pattern for tracing other tapes. A mark in pencil near one end reads: Number. A nearby mark reads: Make.
