The text and graphics of a WBT system can be changed with relative ease. Content modifications are immediate, and information can be distributed instantly to an entire workforce. The true strength of WBT is its capability to evaluate and adapt to the needs of the learner, independent of computer platform. An integral part of WBT is the browser. The browser is a software application used to locate and display Web content.
Most browsers are graphical, in the sense that they can display graphics as well as text.
In addition, most modern browsers can present multimedia information, including sound and video. The shift to WBT is gaining momentum as companies see what other companies are doing and roll out pilot WBT projects. Much of the empirical data on multimedia benefits is based on studies of interactive videodisc courses. The use of other delivery systems such as the Web has yet to be studied to the same extent, as their predominant use is only very recent. At this point in time, it appears that the delivery system is independent of the training approach.
