A "model approach" to teacher education specifies the development of a model of an idealized learning environment. One way to create a model as a real entity as opposed to a written document is to operationalize model classrooms that exemplify the type of instruction desired. The model described here goes hand in hand with the university-based and field-coordinated approach: model classrooms are developed on the university campus and in selected schools. This provides teacher education students with learning environments similar in instructional design. The model classrooms at the on-campus and off-campus sites have certain features in common. They are characterized by a physical organization, a personalized management system, and an instructional scheme, which all emphasize individualized instruction. (JMF)
