Handheld Devices: Toward a More Mobile Campus
- By Mary A.C. Fallon

Personal computing is on the move—if slowly—from the desktop to a more
mobile environment. Handheld devices, connected wirelessly to the campus
network, will certainly change the way we work and communicate. But how
soon, and when? Here, Mary Fallon offers an overview of the acceptance
and use of handheld devices on campus.
Most of the nation’s 3,913 accredited colleges and universities haven’t
launched initiatives that recommend or require students to use handheld
computers. Yet hundreds are experimenting with how to enhance learning
with the mobile devices—hoping to leverage the coming convergence
of wireless networks, Web services, and enterprise applications. Some
pilot projects, like those at Western Carolina University in North Carolina
and Loyola College in Maryland, are sputtering for lack of funds, or because
they aren’t central to the college’s technology strategy yet.
Small Devices, Growing Status
"Handhelds haven’t hit mainstream yet,"
says Mike Lorion, vice president of education for Palm Inc. "They are
still building momentum. Mainstream is a couple of years away." Palm,
which has garnered the lion’s share of handheld sales to college students,
faculty, and institutions, estimates sales to higher education climbed
10 to 15 percent over last year despite a slow economy. Lorion and a host
of educators say that Palm’s persistent financial difficulties don’t seem
to be having a negative effect on college sales.
While handheld initiatives on college campuses percolate, educators and
IT experts debate whether handhelds will supplement or supplant laptop
computers. Meanwhile, looming on the horizon are new types of portable
computers based on Microsoft’s Tablet PC software that could shove laptops
and handhelds aside, or at least give schools more choices. The first
tablets, which can be written on like paper, are being introduced this
month by Hewlett-Packard Co., followed by Acer, NEC, Legend, and Toshiba.
As an alternative, AlphaSmart Inc. licensed the Palm operating system
and in June introduced a mobile computer called Dana, that has a screen
3.5 times larger than a handheld screen and a full-size keyboard. The
Dana costs about two-thirds less than a typical laptop.
Access is the Issue
IT experts anticipate the array of computing form factors won’t be the
driving issue; instead the focus will be on how the range of computing
and telephony devices can share and distribute content and services anytime,
anywhere.
"All the stakeholders have to acknowledge that everyone wants access
to resources in new ways," says Gil Gonzales, chief information officer
for California State University at Monterey, which has a campuswide wireless
network. "Universities need to repackage their content and services for
a growing number of end-node devices—personal digital assistants (PDAs),
tablets, and embedded devices designed for single tasks."
Kendall Whitehouse, director of Advanced Technology Development for The
Wharton School of the University of Pennsylvania—where Palm handhelds
are as commonplace as telephones—is convinced that the most effective
strategy is to create a single universe of information that can be viewed
from different size windows, depending on which type of computer is accessing
it.
For many universities, re-creating all of the institution’s information
to be viewable via a Web browser that can be used by any type of computing
device could prove to be an expensive and daunting assignment. Equally
as challenging as that great leap forward in information access, is translating
anytime, anywhere access into exemplary pedagogy.
CSU Monterey has teamed up with Western Michigan University and received
two grants to develop a business plan for a wireless institute to study
how technologies are used, and to do applied research on how wireless
access changes learning and teaching. They expect new faculty projects
launched this fall will yield some answers by June.
Applications—Present and Future
College educators can expect to be challenged by the paucity of academic
software applications and e-textbooks for handhelds, the lack of professional
development training on integrating handheld computers and wireless access
into instruction, and the snail pace of providers of course management
software to enable handheld computer access to their products’ learning
tools.
"There has not been enough software written for academic purposes, and
you can’t rely on faculty to create robust, enterprisewide applications
for handhelds," says Ray Dannenhoffer, assistant dean for support services
and director of medical computing at the University of Buffalo’s School
of Medicine.
For the most part, colleges with handheld initiatives rely on basic productivity
software such as word processors, spreadsheets, and calculators, and the
ability of handhelds to view specially formatted Adode Acrobat Reader
PDF files and a smattering of e-Books.
But there are some faculty who are exploiting the key attributes of handhelds
to engage students in new ways and to assess their students’ understanding
of subjects.
Physics professor William F. Junkin, of Erskine College in South Carolina
modified an application called Beyond Question for Palm handhelds. The
student-response software works in combination with WebTarget Access Point,
a new wireless technology from TriBeam Technologies that extends the communication
range of the Palm handheld’s infrared ports to 50 feet. The Beyond Question
modification allows Junkin to electronically poll a classroom of students
using Palm handhelds and see their responses displayed on his desktop
computer in the classroom.
"Because I receive immediate feedback, I can determine my students’ level
of understanding at any point in time," Junkin says. "This free flow of
communication keeps students involved, thinking analytically about the
material, and more inclined to discuss their ideas."
Because WebTarget supports multiple users with bi-directional wireless
communication, Junkin can gauge how well students understand a lesson
by sending a set of multiple-choice questions to their Palm handhelds,
receiving their answers within a second or two, and viewing their responses
several different ways.
Junkin can view answers as they correspond to a seating chart, as answers
from a work group, as an anonymous histogram that shows how many students
choose a particular answer, or as a spreadsheet that lets him quickly
spot which students are having difficulty and which ones are ahead of
their classmates.
"I can immediately determine if a single student or the entire class
understands the lesson," Junkin says. "When this [anonymous histogram]
view is displayed for the class to see, students know if others share
their views. Their commitment to an answer increases their desire to participate
in the discussion, but no one is embarrassed by the anonymous display
of the responses."
In a similar fashion, business professor Don Sower of the University
of North Carolina at Greensboro relies on a Palm handheld computer customized
with LearnTrac classroom management software from eLearning Dynamics.
The wireless application gives him the means to get student feedback during
class much like television networks and public opinion experts analyze
live audience responses.

The First Wave: Mobile Medicine
The first discipline to integrate handheld computers is the field of
medicine. Handhelds are as common as stethoscopes at dozens of U.S. medical
schools today. Physicians and student doctors alike are quickly embracing
this mobile, wireless technology to keep pace with their always-on-the-go
work mode and the deluge of new information that informs their daily practice.
Medical schools are leading the way in the deployment of handheld computers
and wireless technologies to monitor student performance, enhance student-educator
communication, improve course management, and ensure that students have
the latest information as they move between classrooms, hospitals, libraries,
and clinics throughout their communities.
About one-fifth of the country’s 125 medical colleges require their third-
and fourth-year medical students to use handheld computers. Even at medical,
dental, and nursing colleges that don’t require handhelds, large numbers
of students own personal digital assistants (PDAs).
Handheld computing at the University of Louisville
School of Medicine
At the University of Buffalo, the largest concentration of handheld devices
can be found in the medical school. "Handhelds, with their instant-on
ability, are a natural for the medical professions. With them you can
provide more-informed patient care right at the patient’s bedside,"
says Ray Dannenhoffer, assistant dean for support services and director
of medical computing at the University of Buffalo’s School of Medicine
and BioMedical Sciences.
In August, the University of Louisville School of Medicine became the
first medical school to provide all of its 594 medical students with the
mobile devices (Palm m500s). "We want to ensure that our students
graduate with the skills they will need to practice medicine in the 21st
century," says Ruth Greenberg, director of health sciences academic
programming for the University of Louisville. "We believe that many
of those skills require technological familiarity. By the time our students
graduate medical school, using a PDA should be second nature to them.
For the most part, I don’t believe having medical students using PDAs
will change how students learn the practice of medicine. At the same time,
however, I do believe the PDA is changing, and will continue to change,
the way physicians practice medicine."
Today, physicians use handheld computers to write accurate prescriptions,
monitor critical information such as vital signs and medication at the
point of patient care or from outside the hospital or their offices, track
patient care, calculate a variety of health indices, and access reference
materials such as pharmacop'eias that explain drug interactions. Some
medical textbooks have been converted into e-Books readable by some handheld
computers. Many of the medical colleges requiring students to use handheld
computers are creating customized applications to track patient care.

Polling with handheld computers "has broadened the discussion participation
in my classes," says Sowers. "People have had a chance to see how their
ideas are shared by their colleagues, and they gain confidence from that."
"Technology is not going to replace the relationship between student
and teacher, it’s going to multiply it," says Robert Harris, president
of Paradigm Research, which recently produced a white paper on LearnTrac.
Going into the second year of a handheld initiative that requires all
first-year undergraduate, law, and medical students to buy Palm handhelds,
University of South Dakota CIO Roberta Amber ech'es that sentiment. She
reports that USD educators have experienced an increase in the interactions
between students and faculty, greater student participation in classroom
discussions, and students developing better organizational skills.
As always, issues bubble around support and training. Preparing this
summer for the second year of its handheld initiative, the University
of Minnesota Duluth found it necessary to invest $50,000 to train computer
science and engineering faculty on how to better use their HP iPAQ Pocket
PCs as teaching tools, and to create software applications to fill the
void, reports James P. Riehl, dean of the College of Science and Engineering
and professor of chemistry at the University of Minnesota Duluth. "You
have to invest money in faculty development if you want to incorporate
handhelds in a meaningful, pedagogical way," Riehl says.
Some of the software void could be filled by course management providers.
They are inching toward making their applications easily readable and
accessible by handhelds.
Chris Vento, chief technology officer for WebCT, believes handhelds "…have
potential—in the next one to two years you’ll see much more traction with
handhelds, but it won’t be ubiquitous for about five years." With that
perspective, Vento isn’t rushing WebCT into making its products handheld
accessible by tackling the basic functions like calendering and e-mail.
Instead, WebCT is trying to determine what applications and level of access
will differentiate them from competitors while maintaining a focus on
enhancing teaching, learning, and assessment. WebCT expects that its first
handheld-specific "learning tools," such as quizzes and polling, will
be introduced this summer.
Wireless Technologies and Handheld Devices
The next wave of technological change is building momentum as campuswide
wireless networks begin to proliferate. Many colleges are installing wireless
access points to provide coverage in libraries or classrooms. And The
Campus Computing Project’s 2002 survey notes an increase in the number
of institutions making wireless access available throughout the campus.
The percentage of U.S. higher education institutions offering wireless
access everywhere on campus via 802.11b, commonly known as WiFi, jumped
from 6.2 percent in 2001 to 10 percent in 2002.
"There has been a big leap in wireless between last year and this year,"
says Kenneth C. Green, director of the Campus Computing Project and visiting
scholar at Claremont Graduate University.
"While wireless local area networks (LANs) are in their infancy, and
they have associated problems such as lack of ease of installation and
configuration, security issues, and scalability issues, one can look ahead
and see dramatic changes in bandwidth, price and ease of use over the
next few years," according to Charles R. Bartel, director of operations,
computing services for Carnegie Mellon University, and John C. Meerts,
director of information technology services for Wesleyan University, co-authors
of a next-generation wireless presentation at the EDUCAUSE 2002 Evolving
Technologies committee meeting this past October.
Wireless LANs don’t have the capacity to address high-bandwidth demand
applications, but they can handle applications such as e-mail, Web browsing,
instant messaging, polling, and small file downloads. The ability of wireless
networks to handle those applications is prompting colleges to encourage
the use of handheld computers and to lobby manufacturers to produce handheld
computers that take better advantage of the wireless network’s capabilities.
Currently, most handhelds require a special 802.11 sled or card to access
the network, or a monthly access service fee much like a mobile phone.
Even if a campus is totally wireless, once faculty, administrators, and
students step off campus, access disappears. One solution may be Bluetooth,
considered a personal wireless network technology, that colleges such
as East Carolina University, Wake Forest University and Carnegie Mellon,
are exploring. The latest HP iPAQ Pocket PC has integrated Bluetooth and
some Palm OS handhelds provide Bluetooth capabilities through a tiny card
placed in the expansion slot.
"Not all learning happens on campus," reminds USD’s Roberta Amber. "Bluetooth
will let students and faculty go into the field and share documents and
information and collaborate easily. Faculty are saying they need this
type of mobility."
Handhelds are still a novelty for many of the 14.5 million U.S. college
students. But because mobile, wireless technology has the potential to
allow people to learn and collaborate anywhere and anytime, it is expected
that during the next five years we will see a big change in the way students
and educators interact—and how information and instruction are delivered
via myriad handheld devices.
