The purpose of this study was to evaluate the effectiveness of short-term distributed online training events using an adapted version of the compressed evaluation form developed by Wisher and Curnow (1998). Evaluating online distributed training events provides insight into course effectiveness, the contribution of prior knowledge to learning, and participants' reaction to the technology. The adapted compressed survey form was found to be a valid and reliable instrument. Participants in the training events increased their knowledge. Furthermore, no relation between prior knowledge and self-reported learning was found. Lastly, participants reported a favorable rating of the technology. Immediate feedback, course relevance and overall course effectiveness were found to be determinants in the learning variable. In conclusion, short-term distributed online training events are effective methods of training Department of Defense employees and military personnel. (Contains 7 tables and 2 figures.)
