Though technology has been instrumental
in changing the structure of curricula, it has its
pitfalls, Dr. Uemura warns, “I love technology.
But technology is not education.
“Technology sometimes tempts us to give
too much information. And sometimes
machines put up barriers between you and
the student. Personal contact is still the
most important aspect of being a good
teacher. But, if I want to show clinical cases
and use the best tools available to teach,
then I have to use visual technology and
relational models. Chalk and a blackboard are
insufficient. In many cases, a digital image is
worth a thousand—even a million—words.”
The Veterinary Education and Technology
Services unit is working to develop a series
of real-life computer simulation models of
diseases and virtual patients using Clinic
Soft, a computer program first developed at
the University of Iowa Medical School that
has been adapted to veterinary patients. As
they review the case, students learn about
pharmacology, pathology, anatomy and use
that information to solve problems.
College faculty are also developing more
responsive systems for tracking and
monitoring patient care so that clinicians,
students, referring veterinarians, owners,
and producers can access records online to
determine patient status. In the VTH, this
means putting records into computer format
so they can be easily retrieved to avoid
delays, especially in critical care.
Dr. Larry Booth, associate professor and
director of Veterinary Education and
Technology Services, discusses the impact
of technology for teaching students and
providing better service to owners, producers
and referring veterinary practitioners. “Where
are we going? Quality information, anytime,
anywhere, means converting things into
useable form and making information available
quickly.” The use of interactive digital
video has had a profound impact not only on
“My constant struggle: I still don’t know the
best way to teach,” said Dr. Etsuro Uemura,
professor of biomedical sciences. “My
main concern is what do students need to
know and how much information and help
should I give them?” As he talks about the
opportunities and challenges posed by the
use of technology in teaching, Dr. Uemura
demonstrates the computer-simulated “virtual
dog” he developed as a teaching tool.
Dr. Uemura’s combined background in
veterinary medicine and computer
programming helps him to engineer innovative
teaching tools that inspire a new generation
of techno-savvy students. His “virtual dog”
provides students with hands-on experience
examining and diagnosing neurological
disorders. To use the program, students
click on various icons—a hand to lift an
eyelid and examine the eye, a box that
generates specific symptoms of
damage to the nerves or brain.
Other models used in the college
provide an animated stethoscope
that transmits the sounds of a
virtual animal’s healthy or damaged
heart and lungs. These simulated models
provide students the opportunity to practice
their examination skills, create a safe
learning environment, and provide teachers
with good assessment tools as they prepare
students to work with live animals.
Traditionally, student assessment occurs
through tests, quizzes, and direct observation
of specific techniques. The lag time between
delivery of instruction and assessment of
student understanding imposes a great
burden on the learning process. Imagine the
impact on learning if teachers received
immediate feedback about how well students
are understanding materials covered in
lectures and discussions.
There is no need to imagine. The college
recently outfitted targeted classrooms with
Personal Response Systems—infrared systems
where receivers are mounted on the walls
and students are provided transmitters that
are “clicked” in response to multiple choice
questions integrated into lectures. Student
responses are then tabulated and posted so
the lecturer can determine how much time
to spend in review of specific material.
teaching and service but also on reducing
the number of live animals used in courses.
Dr. Booth notes that the use of digital video
and digitized images has revolutionized
teaching. “A lot of the cases we see are
seasonal and fall outside student rotation
schedules. Student often don’t get a chance
to see routine and major cases. For example,
students aren’t always in the clinic during
foaling season. Our goal is to work with
faculty to develop a database of digitized
video cases to provide students with
opportunities to review cases they might
otherwise miss during their rotations.”
Digitized video is incorporated as a teaching
tool in a variety of different applications.
Teachers use video-endoscopes to demonstrate
procedures such as examinations of colons,
ears, and joints. A tiny camera projects
images for a classroom of up to a
hundred students. The images can
then be saved and recorded as a
digital movie for future teaching
purposes. This approach eliminates
the cumbersome process of having
each student look through the scope and
decreases the anxiety of the animal being
examined.
Dr. Booth identifies the next teaching tool
on the horizon. “Our goal is to set up a skills
laboratory where students could use realistic
mannequins using tutorials. It’s an ideal
model for student learning. It allows them to
practice and develop a variety of critical skills:
intubation, IV access, splinting, bandaging,
CPR, inserting urinary catheters, giving
injections. Some students are so worried
about the animal that they have trouble
paying attention to technique. If students
practice on a model, they have much more
confidence when they work with live animals.”
Though students seem engaged by the
technology, they are clear about the real
focus and objectives of their education which
is to care for and promote the health and
welfare of animals. A fourth-year veterinary
student comments: “Being a good doctor
is based on who you are and what you put
into it. I started my training working with
teachers who used chalkboards, lecture, and
discussion. Technology can enhance but not
compensate for natural ability.”
