The Keller Plan, which is often referred to as “The Personalized System of Instruction”, was developed in the middle sixties by Fred Keller, J. Gilmour Sherman, and a number of other researchers and educational theorists, and relies upon the Individualized Instruction Model.The key idea behind the Individualized Instruction Model is that learners will not only be able to better understand the materials that are being presented, but that they will be able to effectively retain information for much longer. Those who have the ability to grasp a particular concept in a short amount of time can move on to the next subject, while those who are having a difficulty understanding the concept can move at a slower pace, in order to delve further into the topic. As such, every learner is given the opportunity to get the most out of the experience, even if he/she is in a group with other learners who possess different skill levels or strengths. Another key application for the Individualized Instruction Model within the educational environment is to offer learners of various skill levels and learning styles different learning materials. For example, if a learner is more of an auditory one, instructors can use multimedia presentations via the computer, which he/she can complete at his/her own pace. On the other hand, if a learner is more of a visual one, then the instructor can use graphic textbooks to better illustrate the points of the concept.Individualized instruction is an instructional method tailored to fit the educational needs and skills of an individual learner. This involves changing the pace the information is delivered, the methods through which the content is offered, and the materials distributed.
This principle of individualized instruction is applied in the study by designing a module that caters to one student. That is, the module could be a standalone instructional material which guides the student in his or her learning.
