Twenty-five students enrolled in a community college criminal investigation class were taught with audiovisual materials as a primary instructional strategy. The audiovisual materials used included slide presentations, film strips, movies, and television programs. The students completed a questionnaire on their perceptions of audiovisual presentations, and on the instructional value of specific types of audiovisual presentations and individual media items. The students indicated that instructors failed to summarize or emphasize the major points of presentations, that insufficient opportunities for raising questions were given, and that no opportunities were given to review or to replay presentations. Eighty percent of the students felt that the materials were effective in presenting subjective information. Ninety-six percent were satisifed with the sound and picture qualities of the presentations. All of the students felt that the audiovisual materials used agreed with the announced objective of the course. The students felt that slides were the most effective instructional media followed, in descending order, by movies, filmstrips, and television. A bibliography of 19 references and a copy of the survey instrument are included.
