Chapter 9. New Learning Technology > Computer Based Training (CBT)

Computer Based Training (CBT)

CD ROMs and DVDs work very much like a musical compact disc (CD). A beam of light (laser) reads the information on the disc and produces pictures and sounds on a video monitor. The monitor is usually connected to a computer keyboard or has a touch screen. Disc technology is better than tape because a disc need not run straight from beginning to end. The machine can find any information on the disc quickly, either at the direction of the user or as a response to an answer. This ability is what makes the learning truly interactive.

Well-programmed discs can steer learners according to their interests and abilities. A math lesson will analyze the learner’s mistakes and try to identify a common weakness such as inability to multiply fractions. The disc will then suggest (and sometimes insist) that a review of the skill should be completed before going further.
