This article is an abbreviated version of
the paper entitled How Teaching Should be Conducted
in an IT Era: Back to the Future submitted for publication
in a forthcoming issue of Asian Journal of Surgery.
In a recent issue of The Rapidly Changing Face of Computing
(Harrow, 2000), we are reminded of how far we have come on
the technology evolutionary scale. In 1977, the popular Digital
VAX11/780 minicomputer was five feet tall, cost around $150,000
(USD), weighed hundreds of pounds, contained less than one
megabyte of memory, consumed six kilowatts of power, and often
needed special air conditioning and a raised floor. It cranked
out at one million instructions per second (1 MIPS). Twenty-three
years later, we have the Compaq iPAQ H3600 handheld computer:
five inches tall, weighing about six ounces (including its
battery) and costing about $500 (USD). It has 32 megabytes
of RAM, 16 megabytes of ROM, and delivers in the palm of your
hand 142 times the compute power of the Digital VAX.
The leaps in technology are astounding, but is technology
serving us or are we serving technology? During these last
23 years of escalating computer use in all faculties, its
impact on university teaching is still largely a promise (Larose
et al., 1999). Although widespread computer use has brought
about the development of interesting applications of computer
technologies, such as the Integrated Virtual Learning Environment
(IVLE) at NUS and other e-learning environments, computer-assisted
pedagogy is not commonplace. The integration of Information
and Communication Technology (ICT) into the university environment
has been largely based on the inherent attributes of the technology
rather than its role in contributing towards meeting specific
learning objectives (Doiron, 2000). Will technology continue
to call the shots?
During this same period of time, major corporations and government
agencies around the world have embraced computer-based training
(CBT) as a cost effective and efficient tool to achieve particular
staff training objectives. They also came to recognise the
value of using the systematic approach to creating support
materials for training: Instructional Systems Design (ISD).
ISD proposes a set of instructional models that make use of
various instructional strategy components to produce a course
of instruction (Dick and Cary, 1990). Throughout the years,
classical CBT and Computer-Based Learning (CBL) has been designed
with reference to learning theories developed by David Ausubel,
Albert Bandura and Robert Gagné. Much of todays
pedagogy still adheres to Gagnés five categories
of learning (i.e. intellectual skills, cognitive strategies,
verbal information, motor skills, and attitudes); and the
vast majority of CBT/CBL produced have been based on his behaviouristic
approach.
Although, most CBT/CBL design will address some or all of
Gagnés nine general instructional events (Gagné,
1965), Web-based Learning (WBL) is providing an added social
communication aspect not previously available. Gagnés
events of instruction include gaining attention, informing
learners of the objective, stimulating recall of prior learning,
presenting the new material (stimulus), providing learning
guidance, eliciting performance, providing feedback, assessing
performance, and enhancing retention and transfer. As you
can deduce, some of these events are best handled through
social interaction in a classroom setting rather than being
preconceived and programmed to appear on screen when triggered
by the user. In most CBT/CBL, programmed learning guidance
and feedback is restrictive and impersonal, assessing performance
is weak, and activities for enhancing the transfer of knowledge
are non-effectual.
Recently, the work of social constructivists like Lev Vygotsky,
a Russian psychologist and philosopher of the 1930s, is being
touted as the missing evolutionary link in the education of
Homo Erectus. Vygotsky emphasises the influences of cultural
and social contexts in learning and supports a discovery model
of learning (Luria, 1976). It is up to the student to construct
his or her own understanding in his or her own mind, and the
teacher acts as a facilitator during this process. Learning
should also take place in a meaningful context, preferably
the context in which the knowledge is to be applied.
Regardless of the convenience that ICT brings to teaching
and learning, lecturers more than ever need to reflect on
their role in the learning process. Teaching must be grounded
to basic principles of good practice in tertiary education.
These principles include encouraging contacts between students
and faculty, developing reciprocity and co-operation among
students, encouraging active learning, giving prompt feedback,
emphasising time on task, communicating high expectations,
and respecting diverse talents and ways of learning (Chickering
and Gamson, 1987).
Present ICT can play a very active role in supporting some
of these principles of good practice (Chickering and Ehrmann,
1996). For example, having a course web site with a student
and teaching staff email roster makes faculty and students
more accessible. Students can also benefit from customised
computer-mediated communication (CMC) tools that facilitate
study groups, collaborative learning, group problem solving,
and discussion of assignments. Some IT developers responding
to the educational market needs are producing sophisticated
interactive learning programmes such as simulations, 3D visualisation
and virtual reality environments that provide immediate meaningful
feedback to the learner.
With the plethora of IT and electronic communication tools
available, will the practice of teaching and the activities
that produce learning undergo a radical change? Just as the
adoption of other technologies like the electric light bulb,
the automobile, the telephone and the television, to name
only a few, has changed the way we live, ICT will engender
changes to this and future generations. I believe that as
we endeavour to make perspicacious use of ICT, it will support
meaningful learning experiences, enable collaborative exchanges
without time constraints, and empower students to take greater
control over the curriculum sequence. With this independence,
students will ultimately learn to value ICT for the key role
that it will play in meeting the challenges of life long learning
throughout their career. We are now in the year of Arthur
C. Clarkes 2001: A Space Odyssey, and thankfully HAL
9000 the computer who says, I can tell from the
tone of your voice, Dave, that youre upset. Why dont
you take a stress pill and get some rest. is not in
command of our mission of Discovery. Lets
make sure that we integrate technology appropriately.
