The Power-Load-Margin Formula of Howard Y. McClusky as the Basis for a Model of Teaching

This paper examines relevant writings of Howard McClusky and his power-load-margin (PLM) formula as the nucleus for a teaching-learning model. A teaching model is defined as a pattern or plan which can be used to shape a curriculum or course, to select instructional materials, and to guide a teacher's action. The seven concepts utilized by Joyce and Weil in Models of Teaching serve as the framework for the PLM model. The PLM teaching model fosters mutual respect, shared responsibility, and a spirit of mutual inquiry in small groups or individualized learning experiences. Four phases form the syntax of the PLM model: exploration of the PLM formula, clarification of value set, determination of a sense of direction, and implementation of the educational objectives. Instructional values claimed as direct outcomes of the PLM model include: introduction to the PLM formula, content areas as defined by the learner, and self-enhancement and goal achievement. Nurturant values claimed as indirect outcomes from "living" in the PLM learning environment include: ability to cope with change, respect for the dignity of the person, and interpersonal warmth and affiliation.
