Keller Plan

The Keller Plan, also called the Personalized System of Instruction (PSI), was developed by Fred S. Keller and is based on Skinner's theories of behaviorism. This system is based on:

* Self-paced instruction -- Each student learns as fast as they are capable independently of others, and is free to specialize in their own interests.

* Content chunking -- Material is broken down into small units. Prerequisite chunks must be learned before superrequisite chunks.

* Unit mastery -- Each unit must be mastered before students can move onto superrequisite units. This means students must score above a certain percent on each unit test before proceeding. Tests can be repeated multiple times.

* Statistical tracking -- A later innovation. Students' progress can be tracked statistically to compare their learning speed on individual units against their overall learning speed. This way if a student is having trouble on a particular unit, intervention can be taken.

* The plan requires a great deal of administrative work on the part of the instructor. However, the use of computer technology has greatly reduced this burden. One such program is the computer-aided personalized system of instruction (CAPSI)
