BSA/EUBSA Distance
Learning Concept
Why Use a Distance Learning Strategy?
There are many reasons why BSA/EUBSA has chosen a distance learning strategy
to deliver much of its training to the security experts workforce.
First, the workforce is widely dispersed, making it expensive in time and
money for instructors to travel to the learners. In fact, BSA/EUBSA does not
have enough instructors in any subject to be able to deliver a course to
every part of the security students. It would be almost prohibitively
expensive for learners to come to a BSA/EUBSA facility for a length of time,
courses would become a lot more expensive.
Second, instruction using a distance learning strategy can be designed to
allow learners to fit the instruction into their schedules when it is
convenient for them. They are not locked into a fixed period of time. They
can read printed text, watch a video, or work on computer-based instruction
and still meet their regular responsibilities.
Third, instruction using a distance learning strategy can be designed to
allow learners to progress at their own rates; they can skip over what they
already know or repeat parts they have difficulty with.
Fourth, for many students working in some kind of job somewhere, it would
simply not be possible to participate in a study or training programme, for
simple time reasons.
How Do We Know It Works?
Evaluation plays an increasingly important
role in BSA/EUBSA's distance learning efforts. For some instruction that
carries continuing education credit, BSA/EUBSA uses a final exam that is
designed to measure mastery of the instruction. Information is also
routinely collected on learner perceptions of the instructors, the delivery
medium, the content and other features of distance learning efforts that are
strictly instructional. Many evaluations are being broadened to allow
learners to develop action plans for applying what they have learned on the
job. Thus far, these evaluations indicate that well-designed instruction
using a distance learning strategy is preferred to other approaches.
In the future, a greater emphasis will be placed on collecting data on
distance learning efficiency from a range of key "stakeholders"—supervisors,
distance learning coordinators, group leaders, site facilitators,
instructors, professional associations, and others.
What Makes It Work?
In a
word: PEOPLE. For BSA/EUBSA, this means people at BSA/EUBSA and people
working for us as advisers and tutors. The key players include the learners
themselves and those who support their involvement, this in some cases maybe
an employer, parents etc.
BSA/EUBSA has found that success in distance learning relies first on how
well it is designed. We use specialists in instructional design at every
step, up to and sometimes including implementation. For example,
instructional designers
•establish who the audience is, what training they need, whether there are
any constraints on either BSA/EUBSA or the audience in delivering or
receiving the training
•determine the best media for delivering the training and design the
"package," which may include a mix of media
•develop all parts of the training as designed—for example, computer-based
instruction, video scripts, print-based manuals
•participate in designing and conducting formative evaluation of the design
and materials
•coordinate, in many instances, the delivery of the training by, for
example, preparing facilitators guides, writing scripts for speakers,
holding practice sessions for speakers
TECHNOLOGIES & APPLICATIONS
When planning and implementing distance
learning systems for security related topics, understanding the needs
involved is important. These technologies are organized into three areas:
books, computers, and video. Before beginning a discussion of these
technologies, understanding several concepts will be helpful.
Convergence: While the books,
computer, and video industries have traditionally been separate, today's
changing technological arena is blurring these distinctions. The common
denominator is information in a digital format, making it possible for
telephone networks to deliver video and data services and cable companies to
offer telephone service. Computers are the central means for modern distance
learning formats.
Interaction : The level of interaction
between instructors and learners in distance learning systems varies.
Correspondence courses provide one level of interaction, satellite video
programs to another, and two-way video yet another. Interaction does not
always need to be a real-time communication. Good examples of non- real-time
interaction include voice mail and email.
Distance Learning Systems: A
comprehensive distance learning system will include a combination of
technologies. For example, in a distance learning system that uses video as
the primary method of delivery, voice mail, electronic mail, networked
multimedia databases and fax technologies might be employed for additional
interaction between learners and faculty and to provide support services for
the distance learning system.
Point to point vs. multipoint: As the
name implies, a point to point connection involves interaction between two
locations, and a multipoint connection involves three or more locations
simultaneously. These terms are used to describe all types of conferencing:
voice, data, and video.
Bridging: Multipoint connections are
created using an audio bridge for voice only conferences or a Multipoint
Control Unit (MCU) for connecting video calls. Network based multipoint
services, billed on a usage basis, are available from AT&T, or AT&T's
Definity based multipoint technology can be installed at the customers site
as part of the distance learning system.
Analog vs. Digital: Today's distance
learning technology is a mix of analog and digital technology. These terms
refer to the characteristics of representing information in electronic form.
Analog is a continuous waveform representation that varies by time and
intensity whereas digital representation codes everything into a binary
language of ones and zeros. Traditionally, voice and video technologies were
analog. Computer technology is digital. The convergence of these media is
creating all digital systems. The challenge is to best leverage what exists
today within the vision of the digital future.
BOOKS
Reading assignments have been around for many, many years. They still are an
extremely effective way of learning. BSA/EUBSA uses reading assignments and
book reports to transport the bulk of the basic knowledge necessary for any
competent security expert. We know that many of the more “hands-on”-oriented
students would rather dive right into the adventures… but you cannot expect
gaining any true expertise without true studies. Studying means learning,
and at the end of the day it still comes down to READING, whether you read
in the internet or a “real” book or maybe an eBook.
Reading, digesting what has been read and
writing a book report about it still is probably the best way to
learn and for the teacher to check if a learner has REALLY understood.
COMPUTER TECHNOLOGY
Personal computer technology is becoming the
most important, integrated element for distance learning. Some powerful
applications for computer technology include communication, search and
retrieval of information resources from a global network environment such as
the Internet, access to collaborative learning environments, and desktop
videoconferencing. Since you will almost always need to use computers later
on in your daily work, it makes sense to start using computers all the time.
The technology of computer based distance learning starts with the desktop
computer, and can include a variety of peripheral devices and communications
tools. Connectivity to networks is provided by either a modern and telephone
line or a direct connection to high speed data networks. The computer may
serve as the primary distance learning platform, as in Computer Based
training, or as a support system in other distance learning environments. A
good example of the latter is the use of email for communication between
learners and instructors.
Some applications that use the personal computer platform for distance
learning are:
Computer Based Training (CBT): The
electronic version of the correspondence course, CBT is typically self-paced
instruction that learners access from desktop computers. The training
materials might be installed on the local computer, CD-ROM, Laserdisk, or
accessed from a computer network.
Email: Electronic mail allows learners
and instructors to communicate across time and distance using typed messages
sent over both local and global networks.
On-line classes: This term refers to
courses where lectures, readings, and assignments are posted on computer
bulletin boards and learners access and download the course materials. Other
applications such as email are used for private communication between
learners and instructors.
Computer Conferencing: Interactive
computer based communication environments can be real time "chat" modes
where participants converse by typing on the keyboard or modes where
communications are posted to electronic discussion groups called bulletin
boards.
Groupware: This is the term used to
describe some emerging applications that allow an electronic work space for
collaborative work, sharing of ideas, and group process. Starting with the
conferencing concept above, groupware is able to store, sort, and organize
the inputs of participants and to support group processes such as idea
generation, evaluation and consensus building.
AUDIOGRAPHIC TECHNOLOGY
The combination of the telephone and the
computer creates a distance learning application called audio graphics. In
this environment the telephone is used for voice interaction and the
computer is used for sharing graphic materials and collaborative work.
Participants can interact with visual presentations and audio conference at
the same time. Applications using audio graphics can range from one-time
training exercises to semester-long academic course work.
Each site is equipped with speakerphone, computer and software, modem, and
optional peripheral devices like mouse, graphics tablet, scanner and camera.
Class sessions are set up using the switched telephone network (standard
telephone lines). Some audio graphics systems combine the voice and computer
signals on a single phone line. Other systems use two phone lines, one for
voice and one for the computer. Connections can be either point to point or
bridged into multipoint sessions.
VIDEO TECHNOLOGY
The ability for instructors and students to
see and hear one another brings new levels of Interaction to the distance
learning experience. Collaborative problem solving, demonstration, behavior
modelling, and skills practice are all enhanced by the addition of video.
Distance learning applications using video technology fall into two general
categories, one-way video and two-way video.
One-Way Video: The distinguishing
characteristic with this distance learning application is that video signals
are transmitted in one direction, from the instructor to the learners. The
most common method of delivering the broadcast is by satellite. Components
of a satellite broadcast system include the origination site, the satellite
uplink for transmission of the program to a satellite orbiting the earth,
the satellite transponder that receives the earth signal and retransmits
that signal back to earth, satellite downlink equipment, and finally a site
for people to view the program on standard television monitors.
The program that originates from one site is transmitted by satellite to a
"footprint" that covers a very wide area. For example, satellite programs
originating at one site in North America can be received simultaneously at a
limitless number of sites anywhere in the United States, thus serving a
geographically dispersed audience. Real time interactivity among the sites
and the originating location is accomplished using telephones, data
collection key pads, and faxes.
Two-way Video: Another distance
learning system provides video and audio communications in both directions
between learners and instructors. This is referred to as two-way video. All
locations in a two-way video system are equipped with cameras, monitors, and
microphones. Point to point and multipoint connections link learning sites
and instructors and learners can see and hear each other. These connections
use circuits that can deliver a range of video services. In each system, the
learning site is equipped with cameras, microphones and other peripheral
equipment to support the full range of instructional needs.
Compressed Video: These systems offer
the flexibility of a variety of bandwidth services to the user. The audio
and video signals go through digital signal processing that reduces the
amount of information that is sent from location to location. These
compressed signals can be sent to virtually any location via satellite or
over the switched telephone network. Using digital lines and services such
as DSL, the quality of the picture is a function of how the bandwidth is
used.
Compressed video is widely in use over the internet. This format is the one
in use mostly, when
we
talk about video conferencing
or video in general.
BSA/EUBSA does not use other formats besides the “streaming media” or the
more recent podcasts, of course with the exception of DVD videos.
