"Web-based training (WBT) is an innovative approach to distance
learning in which computer-based training (CBT) is transformed by the
technologies and methodologies of the World Wide Web, the Internet, and
intranets. " Tim
Kilby
Advantages:
- Increased training effectiveness
- Trainee controls pace/sequencing.
- Reduced student time in training.
- Immediate feedback.
- Reduced instructor/staff requirements.
- Standardised instruction.
- Increased trainee participation/interest.
- Tracking of trainee performance.
- Low cost platforms (PC with browser).
- Ease in content update and delivery
Disadvantages:
- Bandwidth limitations may afect performances (video, sound, graphics).
- Requires maintainace and high security
Course content can be perused in a student-led and/or instructor-led
environment.
All content presented to the user (W/CBT, Reference documentation, classroom
overheads etc.) is derived from a single data source; this means that
corrections and additions to the information base need only be made once.
To help keep the user's attention (particularly in a student-led training
situation) the content includes interactive elements; these encourage
the user to participate in the educational experience. These elements
include:
"Virtual Labs"
Graphical, animated simulations, for example to mimic physical
equipment on-screen; these can be especially useful when attempting
to explain a concept that is difficult to describe verbally. As
much of ASTech's work is in the technology sector, training often
concerns mechanical, electrical/electronic, hydraulic & pneumatic
devices. These simulations allow the students to gain a better understanding
of these devices and how they operate. |

Special-Purpose calculators
As engineers, scientists and others in technologically-based fields
are often required to perform calculations of varying complexity
as part of their work. While they may have to become familiar with
the intricacies of these calculations as part of their everyday
work, it is useful, initially, for the student to be able to focus
on the concept being taught rather than the mathematics that must
be applied to carry them out. ASTech include task-specific calculators
for selected exercises to help students "get a feel" for
how the mathematics they learn influence what they see and work
on. |

Multiple-choice examinations
Incorporating periodic examinations within the C/WBT content encourages
students to familiarise themselves with the material being discussed.
In addition to this aspect, as examinations are corrected automatically
at the server on submission, it allows supervisors to gauge how
familiar students are with the subject matter at hand. This can
be used to highlight how difficult students find any given segment
of the course, so that the course material can be adusted accordingly. |
