As part of continuing research aimed at identifying optimal methods for training Navy personnel who have achieved marginal scores on military selection tests, flash card instruction methods were adapted for application to a comprehensive range of basic mathematical operations involved in a previously developed course in fundamental mathematics. Supplementing the standard course work with flash card instruction did not result in significantly higher performance gains, and the study concluded that applying flash methods to the relatively wide range of content complexity involved in this study was not effective.
