This theory of motivation proposed by William Glasser contends that behavior is never caused by a response to an outside stimulus. Instead, the control theory states that behavior is inspired by what a person wants most at any given time: survival, love, power, freedom, or any other basic human need. Glasser (1992) contends that we must offer students an education that they can see will satisfy both their immediate and future needs. Students can only learn if they view their schools as a place that is at least potentially need satisfying.
