Symbol Learning in Navy Technical Training: An Evaluation of Strategies and Mnemonics.
Ainsworth, James S.
Navy and Coast Guard enlisted men were the subjects of a study to determine the effectiveness of various instructional materials and methods in symbol learning. A repeated measures design was used to determine the differential effects of aptitude, type of instructional material, and amount of study time on acquisition of the International Morse Code. Four types of instructional materials were compared: (1) traditional materials (study guide pages and flash cards), (2) a Guided Practice handbook, (3) a Mnemonics Only handbook, and (4) a Guided Practice and Mnemonics handbook. The handbooks with Guided Practice components were prepared with the use of computer-aided authoring routines. Results verified the effectiveness of instructional material designed in compliance with the algorithm for symbol learning contained in "Interservice Procedures for Instructional Systems Development." The use of the three handbooks produced performance levels superior to that obtained with the traditional format. The use of mnemonics had no residual effect on final performance levels (i.e., mnemonics did not interfere with the development of accuracy and speed in the learning of Morse code sent by flashing light). These results indicate the feasibility of using computer-aided authoring routines to produce effective instructional materials. (Author/JB)
