Many diverse Internet/Intranet-based training (IBT) opportunities are now available through academic, government, and commercial sites. Currently available IBT-based programs include the following: full-featured tutorials, half-hour courses, long-term courses, and seminars that can be tailored to user-appropriate levels. Situation-based learning is another effective approach used in IBT. Despite the expectations of many individuals involved in developing and delivering training, the combination of hype, emerging technology, and bandwidth restrictions has made the reality of IBT a challenging goal. Several important verification and certification issues must also be resolved as the use of IBT expands. The experience of IBT developers to date has demonstrated that IBT is no easier to develop or deliver than CD-ROM-based training is. Several experienced IBT developers have published very specific recommendations for individuals contemplating developing and delivering IBT. Training programs that run outside ("swallow") browsers and intelligent electronic mail have been very well received. It is anticipated that Virtual Reality Modeling Language (VRML) will open the door to new online training domains. Other products and/or practices that are likely to be applied more widely in IBT include cellular modem access, synchronous audio and online lectures, and interactive digitized video.
