Evaluation of Electronic Counter-Countermeasures Training Using Microcomputer-Based Technology: Phase I. Basic Jamming Recognition.

Seven microcomputer-based training systems with videotape players/monitors were installed to provide electronic counter-countermeasures (ECCM) simulation training, drill and practice, and performance testing for three courses at a fleet combat training center. Narrated videotape presentations of simulated and live jamming followed by a drill and practice session and performance test were presented to 357 trainees. The objective was to train students in electronic countermeasures (ECM) recognition in a more effective mode than can be achieved through traditional classroom lecture and textbook presentation of jamming examples. The lesson on basic jamming recognition presented training in recognizing and identifying general types of ECM. The microprocessor was programmed to (1) present the materials in response to student input through the keyboard, (2) evaluate student performance and provide feedback when appropriate, and (3) keep a complete record of all responses and response times. The results indicated a significant improvement in posttest over pretest scores, and attitudinal surveys showed a highly positive attitude toward the type of training used. The microcomputer-based training system was effective and reliable, meeting with project expectations. Future project efforts include revisions and extension of the present system.
