Distance Learning: Has the Training Culture Kept Up with the Technology Available

The US Army School of Aviation Medicine (USASAM), in concert with the Center for Total Access (CTA), has developed a study comparing the effectiveness of computer-based learning versus traditional classroom didactic instruction, as measured by a standardized post-test. The accomplishments of the project to date include the following: Development of web-based, interactive course modules utilized to provide the DL instruction. These modules were based upon PowerPoint presentations that are given to resident students at USASAM. Development of a prototype course module interface. Alpha (focus group) testing was performed at the Army's Operational Aeromedical Problems Course (GAP) in Norfolk, Virginia. Beta testing was conducted at the US Army Flight Surgeon Primary Course at Fort Rucker. Internet domains have been registered at: www.avnrned.ha.osd.mil and at www.avnmed.org. Web sites were created on both the .mil and org domains to allow access from home, as well as clinic and deployed environments. Methodology decisions included utilizing a design for 800 X 600 monitor size, and to make the interface as simple as possible to use, for non-web savvy'1 users The Macromedia Flash technology was chosen to deliver content in small file sizes to minimize download time. Lessons learned from alpha testing resulted in the creation of a navigation system that allows students to move back and forth from one slide to another, as well as scrolling through the presentation, or jumping back to a previous, non-sequential slide. In addition, users are able to interact with courses on-line, can read material or print it for later study, in concert or independent of web site. This affords greater flexibility to the end user in choosing the conditions under which he/she learns optimally.
