That gets tiresome. Finally, if there is too much material to read on a page or if there are too many pages or screens in a lesson, the user starts to feel it never seems to end and often will tune out. Tedium and then boredom sets in. Possible ways are to emphasize application and value of the material. Entertainment is also often used to lighten up a training session.
Some developers try to use animations, videos, and sound to keep the user's attention.
Unfortunately, such multimedia effects can cause passiveness or can even annoy the student. If the lesson is valuable to the user, he or she will want to participate and complete it. Value relates to usefulness and application to the job or task. Realizing that the user may not see the value of the lesson and stating points about it will provide some needed motivation. For example, by reading this material and passing the mini-quiz, you will not only be practicing using a CBT, but you will also be getting ideas for your own applications that will accelerate your career.
