A Discrepancy Model for ITV Program Evaluation : An Instrument for Teachers / David H. Jonassen.

Using aspects of the Children's Television Workshop procedure, a theoretical evaluation model is developed which may be used by teachers for previewing instructional television (ITV) programs. Based on discrepancy between teacher goals and expectations, program goals and purposes, and student attention and receptivity, the model assumes that the likelihood of successful viewing of ITV is inversely related to the amount of discrepancy. The model has been synthesized into an evaluation form consisting of a series of semantic differential scales grouped according to teacher, program, and student components. The more numerically equivalent the section averages, the less discrepancy can be expected between components, thus providing the teacher with an indication of the program's success. (Author/JEG)
