Plus, one multimedia-training tool, such as a CD-ROM, can be used or shared among several employees, whereas a human instructor would have to hold several sessions to teach several employees.
The next reason for the recent growth in multimedia training is the accessibility it provides. When using a human instructor, a company may not want to hold a training session until enough employees are hired that could benefit from the training so that the company could avoid holding multiple sessions. With multimedia training, this is simply not true. The media could be used by one person or by a group at relatively the same cost, so it is not necessary to gather a large pool of employees before training can begin. Also, multimedia tools can be delivered just-in-time or whenever the trainees need it. There is no need to work around a trainer's schedule and a trainee's schedule. For example, assuming the employee has access to a computer, he or she could be given a training CD-ROM to take home and study. The employee could then be quizzed the next day to see how much they learned. This seems to be much more advantageous than waiting until there are enough employees who could benefit from the human instructor and then finding an appropriate time that all employees and the trainer could meet. .
Another benefit of computer-based training is its ability to minutely track the learning event. Since the user is interacting with a computer, the system is able to track and monitor each interaction. This can provide personnel with the information they may need to further the learning experience. It can show them what the trainee knows and does not know, what they have learned from using the media, how fast they learned the new information, and how they learned the new information. All of this information would be virtually impossible to collect from a human trainer who had just held a seminar that instructed numerous employees.
