My McLuhan tetrad (Laureate Education 2014,
Thornburg, 2013) is based upon Learning Management Systems. As an educational technology futurist, and
following McLuhan’s example, as taught by our instructor, Dr. Thornburg, I ask
the four essential questions:
“(a) What a technology does that is new (enhances)?
(b) what a
new technology replaces (obsoletes)?
(c) what a
new technology brings from the past (retrieves/rekindles)?
(d) what
might replace the new technology in the future (reverses)?”
Enhances:
The advent of learning management systems brought improved and faster
communication and increased staff and student participation. It improved problem-solving and made for
faster processing. Finances were more
easily integrated, tracked, and organized resulting in higher profits. Customer service became at a higher
level. Data and marketing became
targeted and rich. These findings were the conclusions of the studies at the
boom of the industry (Alavi & Leidner, 1999).
Obsoletes:
Learning Management Systems created an overcapacity of some employees
and services, but not always in the manner anticipated. One would imagine the usage of paper would be
much less but the need for paper continues to exist, and in some ways, more
paper and ink are required as our printers print, print, and continue to
print. As was true in the Industrial
Revolution, the advent of technology in the late 20th century brought an end to
certain jobs because the computer machine could make processes faster and
simpler (Jensen, 1993). No need for so
many teacher’s aids or even teachers. Geographical
limitations in the distance between people have become unimportant with the
LMS. It is perfectly okay that my
instructor lives and works in Nigeria, for example. Schools can become virtual. Offices are virtual. I chose an app and 24-hour support from India
to proof-read my work reports at a less expensive price than a secretary who
used to perform the same function.
Retrieves/rekindles: Learning Management Systems caused energy
usage to increase dramatically. The
postal system and its competitors had increased markedly with the advent of the
technology that developed at the same time when the LMS systems became widely
popular. Teachers became more
accessible. They are just an email
away. Schools such as Walden University
request to please allow your instructor a certain number of hours to respond to
your email. Learning and knowledge have
considerably increased as data, learning circles, and information has
dramatically increased. Global interests
are of greater importance. Technical
jobs are worldwide such that some third-world countries have developed into meaningful
participants in the global economy (BBC, 2010).
For example, technical workers in India help me with my Dell computer,
proof-read my work reports, and assist with my Adobe software.
Reverses: Let’s project out 50 years from now or
more. The LMS can give rise to personal
tutors as preprogrammed hologram images ready to aid the student. The mobile device today which looks up
millions of articles, books, and websites in a matter of a second may transform
into virtual reality tours. Learning about
the middle ages and the travels of the Vikings.
With virtual reality, you are pulled into the scene. Not enough people to make all those virtual
reality tours? No problem, the computer
will do it with self-learning and the current information already on the
internet for it to access. With brain
downloading and uploading, learning disability?
No problem, a quick upload and now a gap-fix can just provide the brain
its needed link. In fact, no need to
learn at all. Second language? How about an upload of 100 languages? Low on storage space, no problem, delete the
80 languages you will probably never need, and if you did need it, you could
upload it later.
