12.2 Computer based Training
Great care must be taken when deciding how to use the computer for industrial training. The
computer is not a panacea; it is an educational tool. But with the current proliferation of small
computers, and advances in computerised instruction systems, industries must consider
computers as at least a partial solution to their training needs.
12.2.1 What is CBT
Computer based Training traditionally is divided into Computer Assisted Instruction (CAI) and
Computer Managed Instruction (CMI). This may appear to be an arbitrary division, but the
distinction is actually quite clear.
CAI is simply individualised training delivered by some sort of computer terminal. The training
delivered can be anything from highly complex situations to simple text. One drawback is that
the instructor’s course-management functions of record keeping and prescription of learning
activities are more difficult because the learners are at different points in the training.
CMI was developed to overcome the problem. CMI supplies the system to administer the
testing, record keeping and prescription generation. The computer gives the tests, grades them,
records the results and prescribes learning activities for learners who do not perform to he
required standard. The computer can also store learners perform and to the required standard.
The computer can also store learners responses for the programme development team to use for
test-item evaluation and other data analyses.
Most computer based training applications involve some overlap and combination of both CAI
and CMI concepts. Therefore, the general term “Computer Based Training” (CBT) is used.
The Advantages of CBT
1. It is self-paced: Learners progress through the material at their own learning speed. There
is no need to gear the training to the slowest learner, as is often the case with classroom
instruction. Self-pacing provides an additional benefit in the industrial environment
because it is adapted more easily to work schedules, thus permitting training to be conducted
at times that are most cost-effective for the company.
2. It allows for variable entry levels: With proper pretesting, the learners start at the point in
the training programme that matches their particular level of skill or knowledge. Pretesting
also ensures that no learner enters the programme without prerequisite skills and
knowledge and allows advanced learners to skip past material in which they are already
competent.
