Biotechnology in online learning systems

Problem


With online learning becoming widespread, many
students have others doing their work for them;
there is a growing need for online universities to
find ways to authenticate student identity.


There is a need to know whether or not the
student enrolled is the one actually doing the
work.


Biotechnology is needed to authenticate student
identity in online learning systems.

Research


There has only been one research done on
this problem by a Ph. D. student, Pranab
Mohanty at the University of South Florida,
School of Engineering, in 2007. His study
focused on using a mantle in which either a
face recognition device, or a hand print
recognition device could be installed on online
systems to authenticate students.

Research

Lead Thinkers: Government Officials


Researchers in the medical field already work
closely with government officials in developing
high tech biotechnology devices. Evidence of
biotechnology is seen in airports, some
intersections, and mostly in crime solving.


Apple and other software companies, that have
touch
-
screen capabilities on their equipment, use
a form of biometric technology (although not to
the capacity identification).


Development


Biometric technology has not been used for online
learning systems fully. It has been noted that
Blackboard uses some form of biometric technology,
but my investigation of this has not confirmed this yet.


One problem that is already seen by
Mohanty

is
invasion of privacy. If online universities use
biotechnology as opposed to having students use
passwords, will they be invading on students’ privacy?
Another problem with this development may be funds.
How much will it cost for universities to install a
biometric device on their learning platforms? Will the
costs outweigh the benefits?

Commercialization


Production

development of device that is
conducive to an online platform learning
system; pilot test, applied research


Manufacture

university funded


Marketing, packaging, and distribution will
depend on the success of the product. In
addition, online learning universities will need
to determine the importance of
authenticating students’ identities.

Innovation

Decision Process of
Biotechnology

Knowledge Stage


Biologists studied organisms and cells



Increase of understanding of organisms and
cells led to control of the their many functions


Examples include: fruit juice fermenting into
wine; milk changed to cheese, yeast cells into
bread, and gene slicing with DNA.

Persuasion Stage



Planting of
crops and
breeding
animals

















Immunology


Genetics


Culture of animal
cells


Bacteria


Penicillin


DNA


Crop mutation

Decision Stage


Implanted biochips used as a tool to track
down lost people by satellite.


Chips used to determine effectiveness of
treatment for congestive hear failure


Chips injected under the skin of diabetic
patients to monitor sugar glucose in blood

Implementation Stage


Food and Drug Administration (FDA) allowed
Pharmaceuticals companies to make drugs and
vaccines.


FDA approved genetically modified watermelons
and tomatoes.


Mining industry used bacteria to extract minerals
from ores.


Environmental Protection Agency (EPA) used
bacteria to digest away pollutants.


Forensics use Fingerprint DNA


Confirmation Stage


Cloning of animals is done by many
agricultural researchers; however, government
allows it to a certain extent (e.g. it can only be
done to improve the quality of animals or
humans not to create completely different
breeds).


Using biotechnology in education for online
identification is an ethical issue; therefore
more empirical studies need to be done to
alleviate any dissonance.
