This booklet, the fifth in a series of eight describing the University of Nebraska-Lincoln and Lincoln Public School System Tenth-Cycle Teacher Corps program, discusses the basic characteristics of the inservice teahcer education component of the program. This inservice effort was developed to complement the ongoing staff development activities of the school in which the Teacher Corps program operated and to supplement a variety of independent activities conducted at the University, which had no organized inservice program. Eight basic principles of the inservice education model are described and illustrated by examples: decision making, needs assessment, voluntary participation, multiple delivery systems, on-site application, formative and summative evaluation, and leadership. Seven basic delivery systems were used to provide activities to teachers, interns and aides: (1) semester courses at school site; (2) individualized modules or mini-courses; (3) curriculum building; (4) team teaching by university personnel; (5) teacher center activities; (6) workshops; symposia, and retreats; and (7) staff development meetings.
