A Multimedia Information Package Regarding Land Application of Wastewater and Sludge: A Study of Training Dissemination Specialists, Evaluation Methods, and Cost-Effectiveness

摘要

It is not always feasible for a research team to participate in the information dissemination process by attending meetings. This project attempted to provide an alternative means of disseminating information by producing, and evaluating the effectiveness of, a multimedia technology transfer package on land application of wastewater and sludge. The package did not require the scientist to be at the presentation. Video and printed materials were produced and discussion leaders trained. Presentations were made in 14 Pennsylvania communities to 310 registered participants. Evaluations were obtained from 136 participants and 12 discussion leaders. Results indicated that the program reached community decision-makers. Overall reaction was favorable although some participants indicated the program's content was too general. The video method of presentation met with mixed reactions. Some participants indicated a need for 'live' experts on the scene. Presentations that combine the use of video materials with a scientist present would be worth considering. The cost-effectiveness of the LAWWS program was determined by comparing its planning, production and delivery costs with those for a similar program presented live by research scientists. The cost of the LAWWS package was found to be greater for the first 43 presentations. After that, LAWWS was the more economical program.
