| Potential advantages of
CBT | Potential disadvantages
of CBT |
1 | Computer-based training is
convenient as it can be available at any time either onshore
or at sea. | This can be 'too convenient' leading to a reduced
emphasis on making the training event as effective as
possible. |
2 | Trainees can work at their own
pace. | There is an optimum pace for most training. If trainees
are allowed to progress too quickly they will retain
less knowledge. If the course is too slowly trainees
will get bored. The pace of training must therefore be a
course design feature. |
3 | Trainees can often go back over
course material to reinforce their understanding of the
material in question. | Trainees lacking in confidence may not progress as
quickly as they otherwise should have. |
4 | Training material is presented in a
far more interesting way than with many other forms of
training. | Course designers can be tempted to 'dazzle' trainees with
impressive graphics which can detract from achieving the
specified learning objectives. |
5 | Three-dimensional images of
equipment and structures e.g. an engine or an evacuation
route, can be depicted to very clearly explain matters to
the trainee. | The course designer must assume that the target audience
can assimilate the information displayed. |
6 | Professional presentations by highly
experienced tutors can be distributed on a world-wide basis
using high quality voice over to clearly convey their
training messages in many languages. | Care must be taken in translating training material to
ensure that the intended message does not become changed
through the translation process which poses a
significant risk. |
7 | The training course can be designed for multi-level
training so that the same course is suitable for a range
of target audiences or to let trainees progress to
higher knowledge levels in controlled stages. | |
8 | Exactly the same training material content is given to
each trainee until the content is deliberately revised
by the trainer, providing a mechanism for greater
control over course delivery than non-automated
training. | |
9 | Training records are very easily stored, transmitted to
other locations, and managed for audit and verification
purposes. | |
10 | | Trainees can not ask computers questions and so are
limited to the pre-determined help facilities designed
into the training course. |
11 | | Computer equipment and software can have compatibility
problems and some means of providing user support is
required. |
12 | Long-term knowledge retention can be higher with CBT than
many other means of training delivery. | |
13 | | Computers can only provide training where the objective
is to transfer knowledge, computers can not transfer
skills to trainees. |
14 | Where the trainee is having difficulty the computer can
provide additional training input as a function of the
trainee's responses to questions automatically. | There is limited ability for group
learning. |
