One procedure that can be used to individualize instruction is to teach different pupils by different methods with the intent of reaching a common goal. A cybernetic (self correcting) procedure is proposed for manipulating instructional displays so that after a period of time the instructional procedure used is optimal for a given individual. This is accomplished by changing the parameter values of those parameters that define a given psychological condition or by changing the values and/or the parameters which define the content-specific conditions of a particular display. The instructional paradigm for each kind of behavior may have many parameters associated with it. A sample of these parameters may be modified, and if the learner response is correct, those modified values are returned to the system, and another set of parameters is selected for modification. If the learner response is incorrect, the same parameters are remodified in accordance with the rules. In this way, the model provides a method to maximize correct responses by the learner. It also monitors performance, and its dynamic property makes it always try to do better. (JY)
