The Teacher Characteristics Project, one of the five undertaken as part of the design of an individualized instructional system for Dade County Schools, was set up to study the role of the teacher in the new system. A survey of literature, research, and projected strategies pointed up these trends and generalizations: (1) a shift in emphasis from the teacher as presenter of information to the teacher as facilitator of conditions for learning; (2) a greater emphasis upon the preactive phase of teaching where the teacher must work with superiors, peers, and myriad sources of data to skillfully diagnose the child and expertly prescribe for his progress; (3) the phase of interactive teaching takes on the challenge of matching teaching style factors of influence management, relatedness, tone, and operational level to learning style of the pupil and learning activity at hand; (4) the teacher's growing role in the evaluative phase of teaching, where the teacher's style must induce objective interpretation of the system as a whole and of his own part in it. Products of the study include a set of operational definitions, a theoretical model for Individual Instructional Staff Assessment (Teacher Characteristics and Behavior Profiles), a Man-Machine Model of Instructional Behavior, and a Teaching Style Classification Scale for use in producing teaching style profiles. (The models and scale are included, plus discussion of implications for staff development and staff organization.) [Not available in hard copy due to marginal legibility of original document.] (JS)
