The many hours required to develop quality computer based instruction make it difficult to produce instruction that is both current and adaptable. Transaction Shells (Merrill, Li, and Jones, 1990) provide novice instructional designers and computer users with tools to aid in the design and delivery of meaningful and easily modifiable courseware while dramatically decreasing the development time. This study was initial pilot study designed to evaluate the effectiveness of the Naming Transaction Shell developed by M. David Merrill and Zhongmin Li at Utah State University. The major finding was that the predicted improvement in development time did occur. The software was tested at the Air Force Academy in Colorado by a subject matter expert with little computer and instructional design expertise. The software was found to decrease development time and produce instructionally sound courseware. Recommendations from the subject include that future versions of the software contain more feedback parameters. Student record management, a feature not yet implemented, was strongly encouraged to be included in the next version. |
