Using "A Model of the Functions of Master Instructor" (HumRRO-TR-73-23) as a guide, procedures and materials for training Army instructors to improve their classroom effectiveness were developed. In constructing the model, various materials on instructor characteristics and responsibilities in four main areas (training programs, classroom behaviors, professional growth, and innovative practices) were gathered from civilian and military sources. Special attention was given to materials devoted to classroom management techniques. Each of the 40 tasks described in the model was carefully reviewed considering three aspects: performance situation, kinds of information needed, and sources of information. The report elaborates on the activities and experiences an instructor would undertake to acquire or update the skills described in the model. The main emphasis is on description of recommended activities to be undertaken in connection with the performance of each instructor task cited in the model. The document concludes with a 12-item bibliography and five appendixes: a model of the functions of a master instructor, a sample system analysis, a sample of matrix terminal and enabling objectives, a sample observation form, and videotaping objectives.
