On my
previous blogs, I have been accentuating on how technology partakes to the
daily lives of people. Most especially, the gadgets we use every day. As a
future educator, it is a must for us to know how these gadgets contribute to
education, particularly the computers.
It was pointed out on EdTech1 the role of computer in
education, and the advent of computer is recognized as the third revolution in
education. The first was the invention of the printing press; the second, the
introduction of libraries; and the third, the invention of computers,
especially so with the arrival of the microcomputer in 1975. Thus emerged computer
technology in education.
Soon computer-assisted instruction (CAI) was introduced using
the principle of individualized learning through a positive climate that
includes realism and appeal with drill exercises that uses color, music and
animation. The novelty of CAI has not waned to this day especially in the basic
education level as this is offered by computer-equipped private schools. But the
evolving pace of innovation in today’s Information Age is so dynamic that
within the first decade of the 21st Century, computer technology in
education has matured to transform into an educative information and
communication technology (ICT) in education.
Typical
CAI provides
·
text
or multimedia content
·
multiple-choice
questions
·
problems
·
immediate
feedback
·
notes
on incorrect responses
·
summarizes
students' performance
·
exercises
for practice
·
Worksheets
and tests.
Types
of Computer Assisted Instruction
Drill-and-practice. Drill and practice
provide opportunities or students to repeatedly practice the skills that have
previously been presented and that further practice is necessary for mastery.
Tutorial. Tutorial activity includes
both the presentation of information and its extension into different forms of
work, including drill and practice, games and simulation.
Games. Game software often creates a
contest to achieve the highest score and either beat others or beat the
computer.
Simulation. Simulation software can
provide an approximation of reality that does not require the expense of real
life or its risks.
Discovery. Discovery approach provides a
large database of information specific to a course or content area and
challenges the learner to analyze, compare, infer and evaluate based on their
explorations of the data.
Problem Solving. This approach helps
children develop specific problem solving skills and strategies.
Advantages
of CAI
·
one-to-one
interaction
·
great
motivator
·
freedom
to experiment with different options
·
instantaneous
response/immediate feedback to the answers elicited
·
Self
pacing - allow students to proceed at their own pace
·
Helps
teacher can devote more time to individual students
·
Privacy
helps the shy and slow learner to learns
·
Individual
attention
·
learn
more and more rapidly
·
multimedia
helps to understand difficult concepts through multi sensory approach
·
self
directed learning – students can decide when, where, and what to learn
Limitations
of CAI
·
may
feel overwhelmed by the information and resources available
·
over
use of multimedia may divert the attention from the content
·
learning
becomes too mechanical
·
non
availability of good CAI packages
·
lack
of infrastructure
