In one of the ‘Teaching Tips’ sections there is an example student response where the binary question is, “Do we have a quiz or a test today?” and to send ‘quiz’ the device method is ‘one quick tug of the string’ and to send ‘test’ it is two quick tugs of the string.
I’m just wondering if people on the forum are viewing the device (string) as binary or not. Here is my thinking and I would love someone to correct me:
The device could be binary if the resting state (the neutral position the kids tend to return the string to) and the element of time was taken into account. However, the method described in the example is more of a ‘tally’ system (not binary).
