This field study constituted a preliminary evaluation of intrinsic programming for automated training. Automated instructional materials used during the first 6 weeks of the Communications Electronics Principles course were presented to beginning electronics students via 35-mm film on the AutoTutor Mark I, a rear view projection machine. Using the Keesler Mathematics Test, three groups-experimental, control, and blind control-were selected and matched from the middle ability range of each of two entering classes. The experimental group received, via the machines, all instruction normally received through lecture and discussion. However they followed the usual method for their practical problems. The students using machines learned adequately from this experimental program. The interpretations of these results and implications for Air Force training are discussed.
