Microcomputers and computer-based instruction.

With the advent of low-cost modular microcomputer technology, discussions of computer-based instruction (CBI) have taken on a new direction. Earlier efforts at computer-based instruction were successful in the technical area, but the expense of starting and maintaining the programs deterred the widespread application of CBI. The initial low purchase price and minor maintenance expenses of microcomputers have lessened financial concerns about equipment purchases. The smaller size and the capability of the microcomputer have allowed CBI system developers to focus on more specific (rather than monolithic) projects so that the time and the cost for program development have been reduced. Although students have demonstrated high interest in CBI, faculties expressed some reservation about entering the field because of the new technology and the lack of supporting evidence for the value of this teaching modality. The microcomputer may be the answer to the economic and attitudinal deterrents to the success of previous attempts at CBI.
