The Little Person Metaphor in LOGO

[Source]

“Under this metaphor, the computer is populated with little people (LPs) who are specialists at particular procedures, and “hire” other LPs to perform subprocedures. LPs are normally asleep, but can be woken up to perform their task. Whenever an LP needs a subprocedure to be run, it wakes up and hires an LP who specializes in that procedure, and goes to sleep. When the hired LP finishes executing its procedure, it reawakens the caller. A “chief” LP serves as the interface to the user, accepting tasks from outside the LP domain and passing them on to the appropriate specialists.

[...] The little-person metaphor has been quite successful as a device for teaching the detailed workings of the Logo language.[10] Sometimes the model is taught through dramatization, with students acting out the parts of the little people. Not only does the model provide a good tangible model for the otherwise abstruse idea of a procedure invocation, but it turns them into animate objects, allowing students to identify with them and to project themselves into the environment. “
