If J. Piaget's six-step paradigm for the process by which all human learning occurs is used to guide teaching methodology, teachers would be able to help students learn in the most natural, authentic, and effective way. Four principles can help translate Piaget's theory into practice: (1) all learning proceeds along a definite causal sequence; (2) human beings learn by doing; (3) only the six-step process leads to true learning; and (4) the causal sequence is divided into two major stages, assimilation and accommodation. To transform these principles into practice, the teacher should decide what to teach first and in what order to present the rest. Then the instructor should devise tasks that will give students the opportunity to practice activities and thinking operations appropriate to each of the six steps. (Included are graphs of Piaget's theory and sample tasks from an introduction to fiction course.) (JL)
