Tools
for Building e-Learning
by
Kevin Kruse
Each producer
selected as a part of an e-learning project team applies a
tool or set of tools to accomplish his or her duties. Here
is an overview of some of the equipment and software choices
available to would-be e-learning developers. Because of the
fast pace of changing technology, a team's technology needs
should be reviewed continuously to ensure that they are the
most efficient and appropriate available. Be aware, it is
very easy for technology wants to supplant technology needs.
The information below is accurate at the time of writing.
However, by the time you read this, the specs and prices will
probably have doubled and been cut in half respectively, further
proof that if you blink, you're behind the times.
Computers
Basically,
the computing power of the machines necessary to create e-learning
exceeds the technical specification of those systems used
to distribute it. The common platform for personal and professional
computers, the MS-Windows-based personal computer, is supplemented
in creative fields such as e-learning production by the use
of Apple's Macintosh computer. Graphic artists coming from
Macintosh backgrounds are largely responsible for this dual
platform development and the reason that so many Macs are
still common in the industry. The figure below presents a
ballpark minimum of the specifications of the computers
used today to create e-learning.

In addition
to these computers, peripherals not necessarily tied to one
user are necessary. The two most notable are at least an 8
speed CD-Burner (the low end of which can now be purchased
for $600) and a color scanner (with a $200-$400 price).
Audio/Video
Equipment and Software
To
independently produce audio and video for multimedia projects,
here are some basic requirements. For audio, which in most
cases will be voice-over narration, you will need a suitable
environment to record sound. A soundproof studio is always
best but an economical alternative is a small, one-person
sound-deadening enclosure such as a "Whisper Booth".
You will additionally need a quality microphone (ranging from
twenty dollars to thousands of dollars but averaging about
$250), and some variety of supporting hardware.
You will
need to route your mic signal through a separate pre-amp or
a mixer with pre-amp capabilities, either of which can be
obtained for approximately $500. An investment in a compressor
will help compress your talent's sounds, retaining sound quality
and avoiding synchronization error if you later have to decrease
the sound's bit-depth, a measure of the complexity of the
representation of a sound in computer code. The audio product
can then be recorded straight to digital audio tape and digitized
afterwards or recorded directly into a computer using applications
such as ProTools, Sound Forge, SoundEdit, or a nonlinear video
system such as Media 100 or Avid. These applications can also
be used to edit the content and most can add any specific
effects that might be needed.
To record
video for multimedia you will first need to choose a format
and purchase a camera. For optimized image quality, a digital
format such as DVCPro is best. A DVCPro camcorder package
can be purchased for about $6,000. The image is crisp and
with the appropriate equipment you can transfer your footage
to an editing suite without going to analog first. Even though
the majority of video for multimedia today is compressed,
the best thing you can do to achieve quality compressed video
is to begin with the best picture possible.
Depending
on your budget and the quality of video you require, additional
items ranging from production lights and backgrounds to a
teleprompter may be required. All of these can be rented,
or, if more cost effective, purchased.
After
you have acquired your footage you will need to transfer it
to an editing station. You will need to purchase a video deck
appropriate to your selected format. Recorder/Player decks
vary greatly in price depending on format and features with
a basic DVCPro deck running $7,000. The editing system you
decide to purchase depends upon it's intended primary use
and factors of cost, speed, and platform. Some may find that
a software application such as Adobe Premier suits their needs,
while others will need a quicker and higher quality system
such as Media 100, AVID Media Composer, or Trinity.
Instructional
Design and Writing
Not
many equipment costs are associated with instructional design,
as most personnel will use common word processors with project-specific
script templates. Design products such as Designers Edge
from Allen Communications, a step-by-step product for creating
CBT scripts, do exist and are frequently used at a relatively
low cost.
Graphic
Art
The
software needed by graphic artists ranges wildly with productivity
needs and designer preference. There is an overlap of products
used to create multimedia and Web products, but specialized
Web tools are required for optimal performance. See the table
below for a brief list of tools.

Authoring
Authoring
applications typically use a metaphor, such as an icon-based
or slide-based interface, to make the structuring of content
and combining of media elements into a cohesive program possible
by the non-programmer. The term authoring system commonly
refers to both multimedia production applications generally
and those intended for training creation specifically. Deciding
between the more than 100 different authoring systems entails
a serious undertaking, shaped by costs, needs, specialties,
and preferences. The icons and flowline systems produced by
Macromedia (i.e., Authorware) and those that rely on
scripted statements produced by Macromedia and Asymetrix (Director
and Toolbook respectively) are those most commonly
used in creating training applications.
WBT
creation requires a different tool set, as the tools function
as filters creating the languages HTML, DHTML, JavaScript,
and Java, which make up Web environments. These tools include
Microsoft's FrontPage and Visual Interdev, Macromedia's
DreamWeaver, ColdFusion and Homesite, to name
a very few. The discussion of authoring systems contained
in Chapter Eight of Brandon Hall's Web-Based Training Cookbook
is a perfect resource to begin exploring development tools.
