A multimedia program for teaching observational and recording skills was developed and validated using a modified research and development model. The program consisted of two slide carousels (192 slides) with accompanying cassette tape and workbook and three supersound 8 mm cassettes with accompanying manual and monitor's guide. These materials are available through the Instructional Media Center of the Exceptional Child Center, Utah State University, Logan, Utah. The model employed two phases to determine program effectiveness. Phase I was concerned with the development and formative evaluation of program materials and procedures. In Phase II the program was validated under field conditions.

The effectiveness of the program was determined by comparing experimental and control groups on post-criterion test scores. The participants also filled out a questionnaire rating various aspects of the program.

Validation of the program was conducted at the Utah State University Exceptional Child Center. Four Special Education and one Psychology classes were used for the main field test. The sample population was randomly selected from class roll lists of the accessible population and consisted of 40 subjects, 20 assigned to the experimental group and 20 to the control group.

Each experimental subject was assigned to two sessions in order to complete the program, each session being approximately 1\ hours in length. The sessions were a maximum of four days apart, and for the majority of students were completed within a 24-hour time period.

The hypothesis that the experimental group would have significantly higher posttest mean scores than the control group was tested. An F value of 129.38 was significant at the .001 level for the total program. These results support the hypothesis. On the Student Feedback Form the program was rated overall at 4.93 on a five-point scale as being highly interesting, of value to them, and an efficient way to present this material.

The subjects reached criterion on the data collecting tasks presented. It was concluded from the post-criterion test and the feedback form results that this multimedia program was effective in teaching the basic concepts of observing, defining, and recording behavior.
