Speak & Spell: A History

The Speak & Spell is a teaching machine specifically in the tradition of B. F. Skinner, reflecting some of both Skinner’s design principles and his theories of learning, decades older than the popular Texas Instruments device. Rather than selecting the correctly-spelled word in a multiple choice quiz, for the example, the Speak & Spell prompts the user to construct the response. It praises; it corrects... The shared features in most definitions of teaching machines include automation, immediate feedback, and self-pacing. The Speak & Spell has all three, using “contingencies of reinforcement” to establish appropriate spelling behavior. (Some of its engineers thought it would be funny if the user received a raspberry or a funny comment when they spelled a word wrong. But this idea was rejected as it would “reward” incorrect spelling.) more
