This study demonstrates the instructional value of supplementary media presentations. A total of 187 first-year engineering students were randomly assigned to 11 descriptive geometry classes. Five classes received multimedia instruction, including televised and 35mm slide programs, in addition to the classroom lectures. The remaining students received no media instruction but completed the same assignments and tests. Data compared each study group in relation to (a) competency in the subject, (b) achievement, (c) visualization of spatial relationships, and (d) attitude toward the subject.
