| Abstract: | Abstract Two experiments investigated the retention of knowledge as a latent measure of learning outcome. Based on an analysis of previous classroom studies, a prediction of a 15% relative loss of knowledge that had been gained during original learning was made for two video teletraining courses, one concerning air traffic control and the other battle staff duties. A total sample of n = 90 participated in the distance learning versions of either of the two courses; a total sample of n = 137 participated in a comparable residence classroom version of either course. Retesting of the same content was conducted ten, twenty, or forty weeks after completion of the course. Results demonstrated knowledge losses of between 14% and 16%, in line with predictions. The merits of knowledge retention as a construct for examining initial evidence of learning is discussed, especially for training related to the safety of others. |
