Preface
During the
early 1990s, many of those interested in the impact of information
technology liked to talk about "paradigm shifts." Despite its attainment
of cliché status, the concept of a paradigm shift is a powerful one.
Most who were once skeptical of the impact of the Internet on the ways
we do business in all facets of society now recognize that our paradigms
are, in fact, shifting.
The word paradigm comes from the
Greek word paradeigma, meaning "model" or "pattern." A paradigm
represents a way of looking at the world, a shared set of assumptions
that enable us to understand or predict behavior. Paradigms have a
powerful influence on individuals and on society because our view of the
world is determined by our set of assumptions about it. To put it
another way, our vision is often affected by what we believe about the
world; our beliefs often determine the information that we
"see."
Extending this concept to technology, a paradigm effect
may prevent people from seeing what is happening around them and from
realizing the potential in a new application of technology. As Jim
Wetherbe, Bobby G. Stevenson Chair in Information Technology at Texas
Tech, puts it, "The biggest obstacle to innovation is thinking it can be
done the old way." Familiar examples of how, in Wetherbe’s words,
"technique lags behind technology" come to mind:
- Faced with the invention of the telegraph, the Pony Express
initially responded by buying faster horses. When that failed, the
organization tried to hire better riders. It did not realize that the
world had changed, and the Pony Express went out of business.
- Shot from a single fixed position while actors paraded in front
of the camera, early motion pictures were essentially stage plays on
film. In 1903 The Great Train Robbery introduced narrative
storytelling to films along with parallel action. Filmmakers intercut
two or more stories taking place at the same time shot from different
camera positions and distances, and an entirely new art form was
born.
- The
first ATM was located inside a bank and was available only during
banking hours. Bankers viewed this technological innovation as an
automated teller. Real innovation did not occur until ATMs were placed
outside banks and in malls, grocery stores, and airports, available
twenty-four hours a day.
As we
enter the new millennium, colleges and universities are offering
thousands of online courses and, in the process, are ostensibly altering
centuries-old methods of teaching and learning. Some would argue that
this represents a paradigm shift. But does it?
There is no
question that the higher education community has moved well beyond the
time-and-place-specific campus paradigm of the 1980s and early 1990s,
when discussions of IT applications consisted primarily of wiring the
classroom or wiring the campus. Most of those engaged in online learning
programs promote the benefits of 24/7 access to courses and degree
programs. Because they may not need to go to campus as frequently or at
all, students also value the flexibility offered by online programs. A
lot has changed.
At the same time, a lot has not changed. The
vast majority of online courses are organized in much the same manner as
are their campus counterparts: developed by individual faculty members,
with some support from the IT staff, and offered within a semester or
quarter framework. Most follow traditional academic practices ("Here’s
the syllabus, go off and read or do research, come back and discuss."),
and most are evaluated using traditional student-satisfaction methods.
This is hardly surprising, since most online courses are offered by
traditional institutions of higher education. To return to our paradigm
discussion, a paradigm provides boundaries for behavior, guidelines for
action, and rules for success. All paradigms give practitioners a
worldview that enables them to solve specific problems. The higher
education paradigm, honed and perfected for hundreds of years, has
served us well.
Leaders of the old paradigm community have a
tremendous amount of time and energy invested in using the old rules.
Consequently, they are often resistant to change and less likely to look
for creative, innovative approaches to new opportunities. In much the
same way that Thomas Kuhn (who first called our attention to the idea of
paradigm shifts) observed scientists trying to "save the theory," so too
do defenders of the old paradigm focus their efforts on old solutions to
new problems.
The problem with applying old solutions to new
problems in the world of online learning is that these applications tend
to produce results that are "as good as" what we have done before—what
is often referred to as the "no significant difference" phenomenon.
Thomas L. Russell’s compendium of more than 355 comparative research
studies suggests that students in technology-based (typically, distance
learning) courses learn as well as their on-campus, face-to-face
counterparts (http://teleeducation.nb.ca/nosignificantdifference/).
These studies have typically been used by distance educators to defend
the quality of their courses and programs against the once-predominant
view that learning takes place only in a physical classroom. What we
need now, however, are new approaches that go beyond producing no
significant difference.
On December 8–9, 2000, in Phoenix,
Arizona, we gathered a group of faculty and administrators—those who
were already "moving the ATMs outside the bank," so to speak—to consider
the question of how to move online learning beyond being "as good as"
traditional education. Before our meeting in Phoenix, we asked
participants to think about how information technology can be used
specifically to address the major challenges of higher education:
improving quality, increasing access, and reducing costs. This paper,
like the symposium discussion, is organized as a response to those
objectives.
As we began our discussion in Phoenix, we asked
symposium participants to do three things. The first was to analyze
their assumptions about distributed learning. For example, although it
is generally acknowledged that the more-effective online learning
environments are learner-centered, there is much controversy and
disagreement about what "learner-centered" means.
Advocates of
"community" may demand residencies or synchronous online sessions,
sincerely believing that such activities are learner-centered. Others
view asynchronous learning environments as a keystone of
learner-centeredness because such environments offer students greater
flexibility. Is asynchronous communication de rigueur if one is
learner-centered, or is synchronous exchange an important part of the
learning experience? All too frequently, even innovative institutions
fall back on a one-size-fits-all approach ("All of our student must do .
. ."), forgetting that students are different and have different needs.
What do we really mean by being learner-centered?
The second
thing we asked the symposium participants to do was to step out of their
paradigms and identify the strengths of each of the distributed learning
approaches that we discussed at the symposium—especially in regard to
particular kinds of students or particular academic topics—rather than
advocating for one approach versus another. Are there some general
principles that distinguish more innovative approaches?
Third, we
asked the participants to explore what needs to be done to improve
online education. Rather than comparing online learning with traditional
higher education, how can we identify new models and talk about what is
better rather than what is "as good as"? What are the important
variables that create a rich online learning experience, one that makes
real improvements in academic practice? How can each of us learn from
others’ approaches and borrow aspects that can be integrated into our
own learning environments?
A few words about terminology are in
order. Throughout this paper, the terms distance learning, distance
education, distributed learning, and online learning are used
more or less interchangeably. At times, the use of distance learning
seems appropriate because the issues under discussion most frequently
concern off-campus (distance) versus on-campus learning. At other times,
particularly when describing the new higher education environment, the
phrase distributed learning more clearly expresses the changing
nature (and the blending) of all forms of higher education. In any
event, the reader should not draw unwarranted conclusions from a
particular usage.
There is a saying among aficionados of
Thoroughbred racing: "It’s not how fast you run; it’s how you run fast."
Our goal in this paper is to show that it’s not providing student
services online; it’s how you provide student services online. It’s the
difference between online office hours and Rio Salado College’s "Beep a
Tutor" idea: immediate on-demand help for students having learning
problems. It’s the difference between a campus bookstore that mails
books to distance learners and a professor who provides a one-click link
on a course Web site to a particular Amazon.com page so that students
can order the required book.
As you read this paper, we urge you
to ask yourselves whether you are taking advantage of the capabilities
of information technology in general and the Internet in particular as
you design online learning environments or whether you are simply
migrating your on-ground approaches online. Only by doing the former
will we move beyond "no significant difference."
I.
Individualization: The Key to Innovation
One can
think of distributed learning programs as existing on a continuum from
rather traditional, teacher-led distance learning programs on the
one end (e.g., faculty teaching via television, faculty putting their
courses on the Web, faculty leading computer-conference-based seminars)
to more innovative, learner-centered programs that rely on a
combination of high-quality, interactive learningware, asynchronous and
synchronous conversations, and individualized mentoring on the other
end. The former programs follow traditional schedules and structures
(e.g., semesters, group meetings), may be delivered to fixed sites or
involve residency requirements, and tend to be developed primarily by
individual faculty members with appropriate IT support. The latter are
modularized and self-paced, may include group experiences as appropriate
and desirable, are delivered anywhere (sites, homes, and workplaces),
diagnose students’ skill and knowledge level as they begin their
programs of study, award credit for learning acquired outside formal
educational structures to enable students to move more quickly through
their programs, and are developed by teams of faculty, instructional
designers, learning theorists, and IT staff, sometimes in partnership
with commercial providers.
An example of a well-regarded
traditional online program is the Master of Science degree in Library
and Information Science (LEEP3)
at the University of Illinois at Urbana-Champaign (see University of
Illinois at Urbana-Champaign. Master of Science Degree: LEEP3). Courses
and programs on the teacher-led end of the spectrum emulate face-to-face
pedagogies and organizational frameworks, striving to make their quality
equivalent to that of on-campus offerings. Programs such as LEEP3 do a
fine job of replicating high-quality campus experiences. But do they go
as far as they might in making significant improvements in the cost, the
quality, or the access dimensions of student learning? Do they take full
advantage of the inherent strengths of the Internet, which enables
greater flexibility, convenience, and personalization?
A
fundamental premise of this paper is that as long as we continue to
replicate traditional approaches online—and continue to treat all
students as if they were the same—we will once again find the "no
significant difference" phenomenon vis-à-vis quality, and we will make
only a negligible dent in the access problem rather than taking full
advantage of the networked environment. And because these approaches
bolt on technology to traditional teaching approaches, they will fail to
reduce costs and, indeed, will frequently increase overall
cost.
Despite the fact that the higher education community tends
to treat quality, access, and cost as three separate and distinct
issues, they are very much intertwined. It is now widely recognized, for
example, that higher education’s historical approach to increasing
quality—adding more faculty, more facilities, more resources—has
simultaneously increased costs. We also know that access will be
directly affected if the cost of higher education to students continues
to rise. So too does a one-size-fits-all definition of academic quality
limit access for students who bring diverse preparation, abilities, and
interests to each learning experience. Conversely, because these three
issues are so inextricably linked, there may be ways to address all of
them simultaneously by using information technology. This paper gives
example after example of how a particular approach to improving quality
can also reduce costs while increasing access. Even though the issues of
quality, access, and cost are addressed in separate sections below, the
interrelationships among them will become apparent.
As we think
about how to design more effective online learning environments, one
thing is clear. We need to treat students as individuals rather than as
homogenous groups. Rather than maintaining a fixed view of what all
students want or what all students need, we need to be flexible and
create environments that enable greater choice for students.
Participants know from their own experience that students differ, for
example, in the amount of interaction that they require with faculty,
staff, or one another. At the British Open University, for example,
approximately one-third of the students never interact with other people
but pursue their studies independently. New York’s Excelsior College
reports that 20 percent of its students take up to 80 percent of staff
time, indicating a strong need for human interaction, in contrast to the
80 percent of students requiring very little interaction.
A
number of institutions, like the University of Central Florida, are
trying to understand possible relationships between students’ learning
styles and online course development and delivery as well as the
implications of that understanding for how we design online learning
environments (see University
of Central Florida. Reactive Behavior Patterns: Implications for
Web-based Teaching & Learning). In a recent paper, UCF
researchers summarized a number of studies that have examined the
learning styles of students who enroll in distance education
courses:
- Boverie, Nagel, McGee, and Garcia (1997) incorporate the Kolb
Learning Style Inventory (1998) into their study of learning styles,
emotional intelligence, social presence and their relationship to
satisfaction with distance education. They conclude that only social
preference exists as a significant predictor of course
satisfaction.
- Tyler and Baylen (1998) use the Learning Styles Exercise
developed by Kiersey and Bates (1978), finding the majority of their
Web-based students are extroverted and judging, contrasting strongly
with the instructor’s preference for introversion and perceiving. They
speculate that differing perceptions of courses may be explained by
contrasts (and potential conflicts) in learning styles between the
instructor and students.
- James and Gardner (1995) propose that learning styles are cast
within a perceptual, cognitive, and affective framework, and suggest
instructional design components for distance education that conform to
learner needs within those three components.
- Verduin and Clark (1991) argue that attention to the mode of
learning preferred by students is important to the instructor who is
designing distance learning experiences. They cite that Canfield
(1983) developed a learning style model and instrument that bears
relevance to online learning, and suggest that maturity has relevance
in learning style considerations.
- Ross and Schultz (1999) make recommendations for the
interaction of online learning and learning styles relying on the
theories of Dunn and Dunn (1978) and Gregoric (1982). They make
specific suggestions for teaching and learning activities that conform
to learning preferences of students.1
One
implication of this research is that we need to think more creatively
about how to develop course designs that respond to a greater variety of
learning styles rather than concluding that online learning is more
suitable for one type of student than another. The University of Central
Florida has determined, for example, that the passive-independent Long
type is more at risk in UCF’s online courses than are other types of
students. Because certain types of students respond more positively
to today’s versions of online courses, some institutions have thought
about counseling students who may not be successful not to take online
courses. Instead, we need to be more thoughtful about course design so
that we include structures and activities that work well with diverse
types of students.
Taking this approach rather than limiting
enrollment in online courses for some students requires real change,
since it requires us both to understand our students as individuals and
to offer many more learning options within each course. This paper is
structured around a series of case studies presented by symposium
participants. Some of these cases deal with courses, others with degree
programs, and still others with institutions. At the symposium,
participants described how their courses, degree programs, or
institutions are trying to move beyond the "no significant difference"
phenomenon by breaking away from the one-size-fits-all approach of
traditional environments, whether on campus or online. We call these
paradigm shifters the new providers.
All of the cases
address increasing quality, improving access, and reducing costs to one
degree or another, some more so than others. Each was selected because
its approach to online learning is in some way differentiated from the
instructor-led, semester-bound "traditional" approach that is
predominant in higher education today. As a whole, they are
characterized by such things as flexible enrollment options for
students; personalized, on-demand, 24/7 student services; innovative
curricular design that includes a focus on applied or problem-based
learning taught by practicing professionals; and learner assessment that
is integrated throughout the curriculum by diagnosing students’
knowledge and skill levels as they begin their programs of study and by
responding accordingly.
Among the new providers, we distinguish
between the groundbreakers, or those who have been leaders in
breaking away from traditional approaches in many respects, and the
new pacesetters, or those who have moved further along the
continuum toward greater individualization for students.
No
institution, program, or course described in the case studies has moved
as fully along that continuum as is possible—and some have done more in
one arena than another—but each illustrates a way to think about moving
beyond the "no significant difference" phenomenon as we gain greater
experience and knowledge about the intersection of online learning and
the individual needs and interests of our students.
II.
Improving the Quality of Student Learning
When asked
about their views on the quality of online learning, most people in
higher education begin by comparing what occurs in an online course with
what goes on in the traditional classroom. A common assumption is that
online learning cannot measure up to the in-class environment. In
contrast, because of their years of direct experience with online
learning, the symposium participants began their discussion about
quality with the conviction that online learning is certainly as good as
classroom learning. Rather than trying to compare one format with the
other, symposium participants spent most of their time discussing the
following question: What kinds of approaches to online learning will
improve the quality of student learning? Consequently, they were able to
come up with many ideas about how to improve quality by taking advantage
of the capabilities of information technology and the Internet. In doing
so, they considerably broadened what we mean by a "high-quality"
learning experience. This new concept of quality takes us far beyond
what is possible in a conventional classroom.
A fundamental
premise of the symposium is that greater quality means greater
individualization of learning experiences for students. This means
moving away from teaching and learning ideas that begin with the thought
that "all students need …" Information technology enables us to meet the
needs of diverse students when, where, and how they want to learn. When
we think about how to utilize technology to improve learning, the key is
to focus on what we can do with IT that we cannot do without it.
Technology can create environments that provide individualized learning
approaches that serve each person in ways that he or she can most
benefit.
Many of the leading institutions described in the cases
in this paper tend to be attached to one way of doing things (e.g.,
synchronous versus asynchronous approaches). They thus illustrate pieces
of the puzzle, if you will. Yet we are moving toward an online
environment that radically increases the array of possibilities
presented to each individual student. The ability to customize the
learning environment so that each student can achieve in a variety of
ways increases the likelihood that learning success online will be
higher than learning success in the traditional classroom, dominated by
a one-size-fits-all approach. Thus, the "right way" to design a
high-quality online course depends entirely on the type of students
involved.
Most of today’s online courses consist of putting the
faculty member’s course online. These "traditional" online courses, much
like their campus counterparts, are developed and delivered by
individual faculty members, with some support from IT staff. Most follow
traditional academic practices ("Here’s the syllabus, go off and read or
do research, come back and discuss."), and most are evaluated using
traditional student-satisfaction methods.
All of the new
providers described below use technology to create a learning
environment that is quite different from the traditional model. As one
symposium participant put it: "We do not put the faculty member’s course
online. Rather we use the faculty member’s expertise to define the
learning outcomes, the applications of that learning, the content, and
potential difficulties that students may encounter." Rather than trying
to replicate a teaching model online, the idea is to create what has
been called a "resource" model, an environment in which students
interact and wrestle with learning materials directly (or in teams),
under the tutorial guidance of a mentor.
Both the groundbreakers
and the new pacesetters agree that students (either directly or in
teams) need to interact with learning materials that allow them greater
choices of assignments and resources. The key goal is for the students
to become engaged in active "doing" in the learning process—that is, to
move beyond merely reading text. Where the two kinds of new providers
part company is the level of individualization to which the course
aspires. While increasing the quality of courses from an
instructional-design perspective, the groundbreakers tend to maintain a
one-size-fits-all approach, holding to the conviction that their
particular model is the "best." In contrast, the new pacesetters create
a far richer learning environment in which students may make a variety
of choices that meet their particular learning needs.
The
Groundbreakers
Rio
Salado College, the University of Phoenix, the British Open University,
and Cardean University share a common approach to course development and
delivery. Rio Salado’s "systems approach" typifies this
model.
Individual courses at groundbreaking institutions are
designed in the context of clear goals and desired learning outcomes set
by content experts. The learning activities required of students are
well thought out and correspond to what we know about human learning. As
an example, UNext’s Cardean University business courses are designed
based on the "learning by doing" philosophy of John Dewey and on current
social constructivist views of learning.
The groundbreakers make
several significant gains in quality when compared with those
institutions using the traditional method of putting courses online.
First, the level of the instructional design, including both pedagogical
and technological aspects, is greatly increased. Rather than the
single-source ("do your own thing") instructional development process
employed by most institutions, the groundbreakers involve teams of
experts in course development. Second, quality-control processes are
more centralized, more collegial, and more elaborate than those in the
traditional approach. Finally, course support structures, both during
development and during delivery, are tightly integrated with the courses
themselves, so that both students and faculty are assured of rapid
responses to their needs.
The New Pacesetters
Virginia Tech, Drexel University, and Ohio State University, all
part of the Pew Grant Program in Course Redesign,2
are developing new approaches that radically increase the quality of
both the students’ learning experience and the learning outcomes
achieved. Ohio
State uses a buffet analogy to capture this new approach to online
learning.
Many believe that mass customization is emerging as the
organizing business principle of the twenty-first century.
Internet-based e-commerce now makes it possible, for example, for
customers to order computers designed to their exact needs and
specifications, obtain customized home mortgages, and compile music CDs
containing any combination of songs. By offering students a buffet of
learning opportunities that can be customized to their learning needs,
Ohio State, Virginia Tech, and Drexel University are pointing the way to
a radically new approach to online learning.
Courses offered by
the new pacesetters have five key features that can improve the quality
of student learning:
- An
initial assessment of each student’s knowledge/skill level and
preferred learning style
- An
array of high-quality, interactive learning materials and
activities
- Individualized study plans
- Built-in, continuous assessment to provide instantaneous
feedback
- Appropriate, varied kinds of human interaction when
needed
1. Assessment of
Knowledge/Skill Level and Learning Style The first step
in creating an individualized learning environment is to assess each
student’s entering skill and knowledge level as well as his or her
preferred learning style. Florida Gulf Coast University (FGCU) offers an
introductory general-education course called "Styles and Ways of
Learning." In that course, students complete the Myers-Briggs Type
Indicator (MBTI) instrument, which identifies students’ preferences
among sets of mental processes or mental habits. The MBTI makes students
aware of the various ways in which they engage the world most
successfully—for instance, through collaborative or individual
experiences and through hands-on or intellectual processes. In its
redesign of its introductory art-appreciation course, "Understanding the
Visual and Performing Arts," FGCU will create learning activities that
build on differences in students’ learning styles so that students can
be directed to the learning activities most suited to their preferred
learning styles, thus giving them a greater chance of completing the
course successfully.
In those environments that take full
advantage of IT’s capabilities, such assessments are incorporated into
course software. In its redesign of introductory statistics, Ohio State
will integrate, directly into its course software, a learning-style
inventory instrument developed by Barbara A. Solomon and Richard M.
Felder at North Carolina State University (http://www2.ncsu.edu/unity/lockers/users/f/felder/public/ILSdir/ilsweb.html).
This instrument, which helps students develop a self-awareness of their
learning style, scores students on their degree of active versus
reflective learning, sensing versus intuitive learning, visual versus
verbal learning, and sequential versus global learning. The course team
will also integrate a study skills assessment instrument, developed by
Ohio State’s Academic Learning Lab, to guide students in making
appropriate choices from the buffet of learning
opportunities.
Riverside Community College’s redesign of its
college algebra course is based on using ALEKS (Assessment and LEarning
in Knowledge Spaces), a Web-based, artificial-intelligence program that
generates individualized student assessments, study plans, and active
learning sets. Through sophisticated modeling of each student’s
"knowledge state" of elementary algebra, ALEKS focuses clearly and
precisely on exactly what the student is most ready to learn at a given
moment. Based on this information, ALEKS creates customized active
learning sets for each student. Students then work through the
customized sets, building momentum, confidence, and ultimately, subject
mastery. ALEKS also provides collective reports on the students in all
classes, pointing out common problem areas that can be addressed.
Because ALEKS is Web-based, it is available to students twenty-four
hours a day, seven days a week.
2. An Array of
Interactive Materials and Activities All the new
pacesetters offer students a broad array of learning materials and
activities. In Virginia Tech’s Math Emporium, for example, numerous
types of learning experiences are available. Students gravitate toward
the kind of experience they find best for them. Since students have
different learning preferences, the availability of recorded lectures
and interactive, Web-based materials enables some students to complete
the course primarily on their own, interacting with faculty and other
students only to the extent required by the course. Others prefer to
take advantage of the variety of support activities and facilities as
well as opportunities to interact with course faculty, teaching
assistants, and peer mentors. By working collaboratively to design the
course, faculty members are able to create, change, adapt, and add to an
ongoing body of materials.
Effective Web-based materials, often
called learningware, go far beyond simply transferring
traditional material to the Web, since a simple transfer cannot improve
learning. Rather than replacing textbooks, these materials supplement
them with activities: interactive simulations that can be actively
manipulated, that provide engaging and challenging tasks, and that
supply instant feedback on performance. Computer games like "flight
simulator" are the ready analogy here; these can be devised in virtually
any field. Good learningware engages the full range of the human senses
through multimedia technology (e.g., visual examples of concepts, short
news clips, or foreign-language conversations that can be reviewed as
many times as a student desires) and almost always forces students to
make learning decisions. In other words, good learningware encourages
active learning.
3. Individualized Study
Plans Unlike
traditional course structures that engage students in the same series of
activities regardless of students’ disparate abilities and interests,
individualized learning environments permit students to move quickly
through content they already know and spend more time on areas they find
more challenging. Students engage in study at their preferred time
rather than at prescheduled times. Students do not all have to do the
same thing but rather learn at their own pace.
The new
pacesetters’ courses are not completely self-paced, since experience
shows that laissez-faire, unstructured, totally self-paced models do not
work well and can lead to high attrition rates. Having freedom and
responsibility for their own learning may be substantially different
from students’ previous educational experiences. The greatest problem is
getting students to spend time on task. Some students are extremely slow
to log in; if students fall behind, they often lack the support to catch
up in time, and many simply won’t make it. Good online programs include
a clear structure that paces student learning and builds in mastery
assessments to certify progress and achievement of learning goals.
Commercial course-management software packages such as WebCT and
Blackboard are able to track students’ time on task online. Students
need help in adapting to this different style so that they do not
mistake freedom of choice for a lack of course
requirements.
Drexel uses the term "self-scheduled" rather than
"self-paced" in describing its new learning environment. Students can
plan their work on a particular module to fit their schedule as long as
they complete each module by the end of the week. Thus, at the end of
each week, all students working on a particular module will have taken
the final assessment for that module and will be at the same point:
ready to move on to the next module. The goal is to maximize students’
flexibility in learning the course material as best fits their learning
preference and schedule while providing enough structure for them to
make the same kind of forward progress as in a traditional course.
Linking students to a definite learning plan with specific mastery
components and milestones of achievement and creating some form of
early-alert intervention system are critical components of course
design.
4. Built-in Continuous Assessment When faculty
members shift the traditional periodic assessment model (midterm and
final examinations) toward continuous assessment, students view
assessment as a learning experience rather than as an all-or-nothing
performance measure. Few people would be surprised to learn that
students, if allowed to do so, will often put off study until shortly
before exams and that such cramming does not lead to long-term retention
of information. Spacing quizzes (either graded or non-graded) throughout
the semester improves overall understanding and retention of terminology
and concepts.
The advantages of continuous assessment include an
increase in the time that students spend studying, a higher level of
familiarity with tested material and of comfort with the testing
process, immediate feedback, and the ability to see the result of effort
on achievement. Assessing students’ understanding of concepts is very
effective in detecting areas in which students are not grasping the
concepts, thereby enabling corrective actions to be taken in a timely
manner, and in preparing students for higher-level activities in the
computer labs. Periodic mastery testing helps students keep up with the
readings and recognize holes in their understanding, and it promotes
understanding of the content. Threading assessment continuously
throughout a course also obviates the threat of cheating.
Online
assessment tools, moreover, have increased in sophistication and now
make continuous assessment more feasible and easier to manage. UIUC’s
Mallard and Michigan
State’s CAPA are two examples of these sophisticated software tools.
Computer-adaptive testing and assessment of individual students’
strengths and weaknesses can craft customized paths of learning that
present learning materials tailored to meet assessed gaps in abilities
and provide tasks that are appropriately challenging. Carnegie Mellon
University has developed an "intelligent tutor" that can follow a
student’s progress and adapt the learning environment to respond to
areas of difficulty a student may have. The ALEKS mathematics software
package can quickly display the location of individual learners or
groups of learners on a particular vector of development, allowing
faculty mentors to plan interventions accordingly.
5. Appropriate, Varied
Human Interaction Helping
students feel that they are a part of a learning community is critical
to persistence, learning, and satisfaction. In many cases, human contact
is necessary for more than just learning content. Encouragement, praise,
and assurance that they are on the right learning path are also critical
feedback components, helping students get through rough times and keep
on working. Knowing that someone is there to help when they get stuck
and to get them moving again gives students the confidence that they can
succeed.
Such active mentorship can come from a variety of
sources, such as traditional instructors (faculty and graduate teaching
assistants) and more advanced undergraduate students. Access to a large
support system of fellow students and tutors who are available virtually
around the clock is a key component to these new
designs.
Students also learn from each other. Research has shown
that students in distance education take on the role of "teacher" more
often than do students in traditional classrooms. This not only has
obvious implications for the content and mode of instruction but also
sets up a model of learning communities that is invaluable when our
students enter the work world. Knowledge-management software can
structure a situation in which students can be actively encouraged to
get in touch online with others who recently encountered and overcame
similar problems.
III. Increasing Access to Higher
Education
When asked
how online learning can lead to greater access to U.S. higher education,
most people think about increasing access to campuses and their current
structures and services. Symposium participants were able to come up
with far more creative ideas about access—ideas that take advantage of
the capabilities of information technology and the Internet. In so
doing, they broadened considerably what we mean by access, moving
beyond giving students who cannot travel to a classroom the opportunity
to participate in higher education. Access means different things to
different people; it does not have a one-size-fits-all definition.
Information technology enables us to expand our definition of access to
meeting the learning needs of diverse students when, where, and how they
so desire. Technology can create environments that provide
individualized access to learning, access that serves each person
in ways that he or she can most benefit.
Symposium participants
generally agreed that the key to designing more-accessible learning
environments is to eliminate constraints. As one participant put it, the
more virtual (anyplace, anytime) the delivery model, the more accessible
it is. Too many distributed learning models still burden students with
the constraints of time and place (someplace, same-time). In addition to
those of time and place, there are academic constraints that contribute
equally to limiting access. Just as the standard semester is emblematic
of time constraints, so do standard academic structures like the
three-credit course or the institutionally based degree program restrict
access to higher education.
Asynchronous learning environments
have done a lot to eliminate the constraints of time and place, but have
they done as much as possible to take advantage of the capabilities of
the Internet? The overwhelming majority of online programs, like their
on-campus counterparts, follow traditional term (semester or quarter)
"class" models, a classic case of applying old solutions to new
problems. Why? Most surely the reason is institutional convenience; few
would argue that students prefer fixed start times. Clearly, information
technology can support new structures that offer greater flexibility for
students. Indeed, without the support offered by information technology,
individualizing instruction is both expensive and logistically
challenging. Once an institution recognizes how information technology
can manage a more diverse approach to organizing instruction, there is
little reason to retain a lock-step approach.
The
Groundbreakers
In
contrast to prevailing practice, Rio Salado College, the University of
Phoenix, and Cardean University have revolutionized the college
calendar. At all three institutions, entering students do not have to
wait until the next semester begins in order to enroll. At Rio Salado,
students have access to more than two hundred online courses, the
majority of which start twenty-six times a year (the remainder usually
start six to eight times a year). This means that any student who wants
to take a course never has to wait more than two weeks to start. In
addition, although each course is advertised as a fourteen-week class,
students are allowed to accelerate or decelerate as needed. Rio never
cancels a class that is offered online. If only one student enrolls, he
or she can be accommodated. Information technology provides the
management system that enables faculty members to handle several starts
at once, keeping everyone on track.
The University of Phoenix
uses a rolling-cohort model in its online programs, enabling a course to
begin as soon as eight to thirteen students are ready to start a
particular study. Cardean University also allows its MBA students to
begin at any time, once a cohort of about twenty-five is established. In
both cases, students share a common discussion environment and an
instructor, whose role is to build community and facilitate students’
discussion of the application of course concepts to their work
environment.
The University of Phoenix, like Rio Salado and
Cardean, makes flexible access to its programs and courses one of its
highest priorities. Study at each of these institutions is primarily
asynchronous. Each has a focus on providing greater access to learning
for working adults—the majority of whom are isolated from typical
college classrooms by time, geography, or transportation barriers—and
each has designed its environment accordingly. When these institutions
survey students about what they like most about their programs, the
convenience factor of having access to education when students want and
need it always ranks high.
The New Pacesetters
Just
as information technology enables institutions to create more flexible
access to existing courses and programs by eliminating the constraints
of time and place, so too does it allow us to expand our definition of
access to eliminate academic constraints. Pacesetting institutions are
increasing access via information technology in three important
academic dimensions: academic resources, degree programs, and
learning through modularization.
Increasing
Access to Academic Resources Some
institutions are going beyond creating access to tradi-tional faculty
and other academic resources. Rio Salado has found a way to eliminate an
academic constraint—the need for students to come to the physical campus
to take laboratory-based courses. Rio teaches anatomy and physiology
courses completely online using virtual techniques, reducing laboratory
costs without sacrificing quality (see Rio
Salado College, Online Human Anatomy).
Out of several hundred
online courses offered by Rio Salado, four science courses rank in the
top eleven, an indicator that students want this expanded kind of
access. At the British Open University, expensive or dangerous home
experiment kits (e.g., chemistry laboratories, telescopes, microscopes)
have been replaced by virtual instruments and experiments. Most science
courses at the university are CD-ROM-based. In addition, both Rio Salado
College and the British Open University emulate field trips online
(e.g., field trips by geology students have been replaced by virtual
field trips that can draw more easily on high-quality support
materials).
Increasing Access to Degree Programs Whereas most
people in higher education think about access within a construct of time
and place, symposium participants pointed out that academic policy
constraints are frequently more potent. Expanding access to higher
education requires overcoming the many academic barriers established by
individual institutions. The issues of access to full-degree programs
and of credit transfer among multiple institutions have been a challenge
to colleges and universities for many years, but the existence of the
Internet and the explosive growth of online learning have radically
escalated their importance.
Although not all online learners seek
degrees, many do. Public-policy goals that drive most virtual university
efforts, for example, include increasing the number of degree-program
graduates. As one symposium participant commented, it is an accepted
truism in higher education that adult learners will not begin a degree
program if they cannot see how they will complete it. If online learning
is going to expand access significantly in the near future, we will need
to increase the number of degree programs that students may complete
entirely at a distance.
Institutions that accept transfer credits
or work experience relatively freely, while offering virtual degree or
certificate programs, are especially effective at increasing access.
Many students may prefer to take courses from more than one institution,
and this trend is accelerating.
At Excelsior College, students
can pick and choose how they will complete their degrees and which
learning services they need to advance their educational goals,
depending on their particular life circumstances. Some students use all
of the Excelsior College learning services, some use none, and some pick
and choose. Some students complete their degrees exclusively through
credit-by-examination, some take courses from many different
institutions, some rely on distance education courses to complete their
degrees, and some attend only one institution in their local
communities. Some students take a few examinations, a few distance
courses, and a few classroom courses taught at one or two local
institutions. In addition, since Excelsior places no caps on the kind or
amount of transfer credit that it will recognize from regionally
accredited colleges, students do not need to repeat learning they have
already achieved in other collegiate settings. The college thus reduces
the total number and cost of courses that students must take to complete
their degrees (see Excelsior
College, What You Know Is More Important than Where or How You Learned
It).
Students at Excelsior College have neither cohorts nor
calendars. They can create programs of study that combine on-campus
courses, online courses, test preparation, and independent study to
individualize the time and place of study while achieving common
learning outcomes as validated by Excelsior’s highly regarded
standardized examinations. Trading academic residency for rigorous
assessment clearly expands access to higher education.
Increasing
Access to Learning through Modularization To make
learning available to the greatest number of people, we can modularize
or break down educational content into smaller chunks that can be
reorganized or recombined to meet the learning needs of individual
students. Modularization characterizes most of the features of the
buffet-style courses described in the preceding section on improving
quality.
By modularizing course content, pacesetting institutions
are able to tailor the study to different types of students with
different goals. Like Ohio State, Drexel University is exploring how
modularization can benefit both students and institutions (see Drexel
University, Modularizing Computer
Programming).
Modularization moves us further along the
continuum from what has been called just-in-case learning to
just-in-time learning. As applications of information technology
become more sophisticated, we can identify weaknesses in students’
learning as they progress through a course. Students can then focus on
these areas of weakness and spend less time on content areas they
already understand. Customized learning materials can be presented to
students in order to provide more practice and/or greater variety in the
types and levels of difficulty. With such focused study, students can
potentially decrease the time they spend on a particular course,
increase their success rates, and reduce the number of times they repeat
a course, all of which play an important role in increasing access to
U.S. higher education.
IV. Reducing the Costs of Teaching and
Learning
When the
issue of cost is raised in relation to online learning, many people in
higher education focus on the question, does online learning cost more
or less than traditional instruction? The predominant belief is that it
costs more. Temple University’s president, David Adamany, typifies the
views of many; he was recently quoted in the Chronicle of Higher
Education as saying, "No one has yet found a way for online learning to
be economically viable."3
The
issue of cost is directly related to that of access. As one symposium
participant noted, it is very difficult for most existing institutions
to expand access, whether on campus or online, without facing
significant budget increases. Without new funding sources, enrollments
can only expand on the margin: where courses and programs have
insufficient enrollment and new students can fill empty seats. A
contributing factor is that productivity in higher education is
declining. Between 1977 and 1997, the number of students in higher
education has increased by 27 percent while the number of faculty has
increased by 56 percent, resulting in a decline in the student/faculty
ratio from 16.2:1 to 15:1.4
One
symposium participant commented that faculty, via threats of
unionization, had forced the participant’s institution to limit the
number of students in online courses to twenty, which in turn limits the
ability both to scale (i.e., produce more cost-effective courses) and to
serve more students (i.e., increase access). Indeed, a new, emerging
paradigm for traditional online courses calls for a 20:1 (or less)
student/faculty ratio, reflecting the on-campus small seminar. Campus
leaders are rightly concerned that such applications of information
technology are increasing instructional costs rather than controlling or
even reducing them. Online learning offers enormous possibilities for
guiding and managing instruction, for communicating with students, and
for assessing student performance and knowledge on a much larger scale
than is currently the norm if we can change the student/faculty ratio.
The issue is, how can we handle large numbers of students
cost-effectively?
Rather than simply comparing the costs of one
form of instruction with another, symposium participants were asked to
consider the following question: What kinds of approaches to online
learning do you believe can lead to a reduction in instructional costs?
By thinking of ways to take advantage of the capabilities of information
technology and the Internet and, in so doing, by reconceptualizing the
way that courses are designed, participants were able to come up with
many creative ideas about how to make collegiate instruction more
cost-effective.
The highest cost component of instruction is
faculty personnel. Currently, the job of a faculty member—whether in
class or online—is seen as monolithic: a collection of tasks that are,
with few exceptions, carried out by one person. Faculty usually believe
they must and will play all roles in the course-development and
course-delivery process. Traditional online providers suffer from what
one symposium participant called a "craft mentality," in which a
high-priced faculty member is her or his own developer and technical
support person, not to mention learning theorist. Information technology
offers the possibility of altering this paradigm. Once the many roles or
tasks that a faculty member performs are disaggregated—that is,
separated and seen individually—the opportunities for substitution and
cost reduction become clearer.
Higher education has known for
decades that substituting cheaper labor for more expensive labor reduces
instructional costs. The use of graduate teaching assistants, adjunct
and part-time faculty, and other instructional personnel has enabled
institutions to keep their costs from rising beyond what they are now.
The knock has always been that our dependency on part-time faculty
reduces the quality of instruction, and anecdotal evidence seems to
support that view. The academy, broadly, worries about institutions that
rely too heavily on adjunct faculty for two reasons: (1) the academic
program may fall into the hands and control of administrators who make
decisions based on financial expediency rather than academic quality;
and (2) quality assurance may be difficult to maintain, since the
academy has neither the infrastructure nor the culture to support a
close monitoring of ubiquitous and disenfranchised adjunct
faculty.
Both the groundbreakers and the new pacesetters follow a
strategy of substituting cheaper labor for more expensive labor and of
employing more differentiated kinds of labor in both course development
and delivery. What distinguishes their methods from higher education’s
historic approaches? First, both types of new providers rely on
technology-based, common or centralized development of course structures
and course materials, enabling a much tighter level of quality
control.
Second, both take advantage of the ability of IT to
disaggregate instructional roles to even greater levels of granularity
while ensuring overall course coherence. Third, both reduce the
duplicative development costs of individual faculty members and enhance
the quality of instructional and assessment materials. And fourth, both
enable multiple faculty to teach the same material and thus to handle
more students.
The Groundbreakers
Originated by the
British Open University and replicated with their own twists by the
University of Phoenix, the Dallas Community College District, and
Cardean University, groundbreaking institutions focus on creating an
efficient course-development process and supporting that process with
tools that increase efficiency. The model is one in which large,
up-front investments are made in single courses, using the best
expertise possible in the development team, with the expectation that
very large numbers of students will ultimately enroll. In 1999, for
example, the British Open University piloted what is now its most
successful online course—"You, Your Computer, and the Net"—with 800
students. This year, the course had a total student cohort of some
12,000.
For course delivery, the groundbreaking model employs a
relatively small core of full-time faculty to set academic standards,
oversee curriculum, establish academic policies including degree
requirements, and so on. Part-time, adjunct faculty carry out the bulk
of instruction. The University of Phoenix, for example, has 240
full-time faculty and more than 8,000 part-time practitioner faculty
members. Rio Salado has 25 permanent faculty and 750 adjunct faculty.
Quality control is strong because, in each case, courses are developed
and monitored centrally, unlike the adjunct model used by most
traditional institutions in which part-timers have relatively free rein
to teach as they like.
Despite their gains in cost-effectiveness
on many fronts, several of the groundbreaking institutions have created
a relatively expensive delivery model by restricting the student/faculty
ratio to anywhere from 9:1 at the University of Phoenix to 25:1 at
Cardean. To support the smaller ratios, Phoenix charges one-third more
tuition for its online courses than for its classroom-based courses.
While taking advantage of IT to coordinate course development and to
ensure a high level of quality control over course delivery, these
institutions have failed to exploit fully IT’s disaggregating
capabilities. For examples of how this can be done, we turn next to the
new pacesetters.
The New Pacesetters
Encouraged by
the Pew Grant Program in Course Redesign, several institutions are
pursuing an alternative to large, up-front investments in course
development. This model takes advantage of existing materials that have
been developed commercially or by other universities. In its online
college algebra courses, Rio Salado College, for example, requires
students to purchase Academic Systems mathematics software just as they
would purchase textbooks. Rio then uses this commercially produced
software as the foundation for its online mathematics courses. In
addition to defraying the cost of materials development, basing the
course design on sophisticated software enables instructors to handle a
higher number of students (from 25–30 to 125) in their courses, thus
further reducing the overall cost per student.
Like the
groundbreakers, the new pacesetters reduce course-delivery costs by
using technology to serve large numbers of students. Their efforts are
differentiated by the further disaggregation of the faculty role and the
substitution of technology-based interactions for human labor. Though
appearing more traditional than the groundbreaker model in many
ways—especially since full-time, tenured faculty frequently serve as
lead faculty in course delivery—the new pacesetter model is, in fact,
more radical and thus offers greater possibilities for both cost savings
and quality improvements. A straightforward example of this approach
is how the University of Illinois at Urbana-Champaign (UIUC) has doubled
enrollment in foreign language courses by relying heavily on Mallard, a
UIUC-developed intelligent assessment software program that automates
the grading of homework exercises and quizzes (see University
of Illinois at Urbana-Champaign, The Spanish
Project).
Pacesetting institutions are breaking through the
small-seminar model for online instruction and are creating new
paradigms that are both high-quality and cost-effective. Once again,
individualization is the key idea. Our buffet metaphor is appropriate
here. Rather than serving a "fixed meal" of instructional resources,
these new designs allow students to take advantage of resources
according to their own needs. Redesign involves moving from an expensive
and inefficient push strategy, which presents all material to all
students in the same way and at the same time regardless of their
particular needs, to a pull strategy. Students access the material they
need when they need it, an approach that takes into account differences
in learning preferences and abilities. The latter strategy is not only
more effective in dealing with learning issues but also more economical
in dealing with resource issues because students use only as much
resource as they need. Organized around computer-based assignments, with
on-demand tutorial assistance provided as required, these new designs
are dramatically reducing both student failure rates and instructional
costs.
High-cost, full-time faculty members are no longer the
only resource. Instead, resources are matched to the level of difficulty
and type of instructional task. Different types of personnel are
employed to do different kinds of tasks. In its redesign of its college
algebra course, Rio Salado, for example, has found that 90 percent of
students’ questions were not math-related and did not require a faculty
member to respond. Rio hired an aide to answer these questions, leaving
the faculty member free to respond to content-related questions and
consequently to handle more students. Possible substitutions used in
pacesetting courses include nontenured for tenured faculty, adjuncts for
full-time faculty, graduate teaching assistants for various kinds of
faculty, undergraduate teaching assistants for faculty or for graduate
teaching assistants, and professional staff for traditional
faculty.
As an example, Virginia Tech has redesigned its linear
algebra course, taken each year by 2,000 first-year students majoring in
engineering, physical science, and mathematics. Virginia Tech, like most
other higher education institutions, tried to control costs in the
traditional mode by employing a mix of tenure-track faculty (ten),
instructors (thirteen), and graduate teaching assistants (fifteen) to
teach thirty-eight sections of the course. The redesign radically
changed the mix of human and technological resources, resulting in a
two-thirds reduction in the cost per student (see Virginia
Polytechnic Institute and State University, The Math Emporium:
Student-paced Mathematics 24x7).
Although many believe that learning environments targeted to
particular learning styles and individual learning needs are more
expensive than traditional one-size-fits-all methodologies, the
introduction of new designs based on information technology can allow
for more cost-effective ways of learning—cost-effective for both the
institution and the student. As noted above, the new pacesetters’
buffet-style courses have five key features that can improve the quality
of student learning. These five features are also major contributors to
cost reduction.
1. Assessment of Knowledge/Skill Level and Learning
Style A first step in
implementing a pull strategy in which students use as much instructional
resource as they need is to assess their knowledge and skill level as
they enter the course or program and determine their preferred learning
style. Based on those assessments, students can then elect the most
efficient path through the required course materials. Drexel’s modular
approach to its introductory computer programming course, for example,
allows students to earn from one to three credits based on their
performance on a knowledge and skills placement test. Students do not
need to spend time covering material they already know and can move on
to other studies. Drexel can reduce the amount of instructional
resources to correspond more accurately to students’ needs. Similarly,
Ohio State’s modular format will enable it to eliminate one-fourth of
the course repetitions, thereby opening slots for an additional 150
students per year.
2. An Array of
Interactive Materials and Activities Each of these
new learning environments reduces the number of lectures and/or class
meetings, replacing presentations of content with a variety of
activities supported by interactive software. Some eliminate several
lectures; others eliminate all lectures. The premise is that faculty do
not need to spend as much time (or any time) presenting information.
Lectures are replaced with a variety of learning resources, all of which
involve more-active forms of student learning or more-individualized
assistance. In many instances, computer-based tutorials and feedback
substitute for instructor-based tutorials and feedback. Such a strategy
is not only more effective in dealing with learning issues but also more
economical in dealing with resource issues because students use only as
much resource as they need. Savings occur from reducing the number of
instructors required and also from freeing up classroom space. Reducing
classroom contact hours, for example, from three to one or two through
the use of virtual instruction makes it possible for up to three courses
to use the classroom hours previously reserved for one
class.
3. Individualized Study Plans Without the
availability of information technology tools, creating and managing
individualized study plans for students would be highly labor-intensive
and hence costly. Sophisticated course-management software, however,
enables faculty to monitor students’ performance, track students’ time
on task and overall progress, and intervene when necessary to correct a
student’s deviation from planned study on an individualized basis.
Students can create a definite learning plan requiring periodic log-ins
(e.g., students have to take a quiz by—not at!—a fixed time every week
and an exam by a scheduled date at the end of each module). Many types
of communication can be automatically generated to provide needed
information to students. Instructors can use e-mail to communicate with
students as a way to encourage students to "come to class" with online
materials. Regular weekly, computer-generated e-mails can inform
students about their progress and, if necessary, suggest additional
activities based on homework and quiz
performance.
4. Built-in Continuous Assessment The automated
grading of homework (exercises, problems), low-stakes quizzes, and tests
and exams for those subjects that have correct or easily assessed
outcomes not only increases the level of student feedback but also
offloads these rote activities from faculty and other instructional
personnel. The result is either a reduction in the number of required
instructors or the ability to increase the number of students in any
given course. Michigan State has shown that the application of
technology can reduce the instructional costs of large traditional
lecture courses from 10 percent to 30 percent. The largest cost savings
was due to the reduced need for teaching assistants for grading and
recitation sections.
5. Appropriate, Varied
Human Interaction Faculty who
teach traditional online courses frequently complain about overload due
to the difficulty of responding to numerous e-mails or managing
complicated listservs. The best of today’s threaded discussion
technologies enable easy-to-access and easy-to-manage communication
among students and between students and their instructors. Wise
instructors may seed class-wide discussions and monitor these
discussions, but they seldom take responsibility for responding to every
posting by a student. They emphasize student-to-student interaction and
interaction with the material in ways that force students to formulate
most of their postings for peer review and response by their fellow
students. Instructors who use these technologies and pedagogies ask
students to take more responsibility for their own learning. By
emphasizing student-to-student mentorship and interaction as much as
possible, we can increase student involvement and improve learning
outcomes. This not only is effective but also saves expensive faculty
time.
V.
Sustaining Innovation
Throughout
this paper, we have reiterated the view that individualization is the
key to moving beyond the "no significant difference" phenomenon.
Currently in higher education, both on campus and online, we
individualize faculty practice (that is, we allow individual faculty
members great latitude in course development and delivery) and
standardize the student learning experience (that is, we treat all
students in a course as if their learning needs, interests, and
abilities are the same). The conclusion reached by symposium
participants is that we need to do just the opposite: individualize
student learning and standardize faculty practice.
It is curious
that most academics react with horror at the thought of standardizing
faculty practice but do not think twice about standardizing the student
learning experience. With its connotations of words like regulate,
regiment, and homogenize, the word standardize does not
precisely capture what we mean. What we need is greater consistency in
academic practice that builds on our accumulated knowledge about
improving quality, increasing access, and reducing costs. Sustaining
innovation depends on a commitment to collaborative development and
continuous quality improvement that systematically incorporates feedback
from all involved in the teaching and learning process.
The
Internet offers unprecedented opportunities to collect, organize, and
analyze large, real-time research. Online environments provide enormous
information-capturing potential because every move that every student
and every faculty member makes is potentially recoverable and able to be
analyzed. Sources include responses to online surveys regarding student
satisfaction and perceptions; tracking of learner behavior on site (On
what learning points do students spend the most time? What is the
sequence and pattern of interest? What questions do students ask?);
transactional data on student registrations, dropouts, and completions;
and interaction and outcome data generated from baseline assessments,
exercises, and exams.
To take advantage of these capabilities, we
need a new kind of "institutional research" designed to determine which
are the most efficient and effective paths for different kinds of
learners in particular curricula or courses, so that we can make active
adjustments in learning designs. We also need to be much more
sophisticated about monitoring and measuring costs. Students,
instructors, institutions, accreditors, and consumer agencies all have
access to this data, enabling benchmarking and competency assessment.
Because of the feedback available, digital products and services can be
fine-tuned, and product development can be accelerated. The ultimate
vision here is the kind of continuous quality improvement systems used
by automated industrial production systems that are for the most part
self-monitoring.
It is not coincidental that the new providers
discussed above have taken the first steps toward implementing this
vision. At the institutional level, Excelsior College, Rio Salado
College, the University of Phoenix, and the British Open University are
known for building a continuous assessment loop through the collection,
analysis, and dissemination of data. In monitoring the quality and
effectiveness of its academic program—the strengths and weaknesses of
the materials and services provided—each keeps an eye primarily on two
things: student learning outcomes and customer and student satisfaction
with all experiences at the institution. Excelsior College, for example,
does a major student-satisfaction survey every three years. For each
graduate, the college does a six-month follow-up survey and a three-year
follow-up, as well as an additional three-year follow-up for students
who complete graduate school. The University of Phoenix conducts
end-of-course surveys among both students and faculty in order to gauge
the success of both the individual class and the individual instructor.
The British Open University tests and edits its courses based on
assessment data that is collected throughout the course-development
process.
At the course level, Virginia Tech, Michigan State, the
University of Illinois at Urbana-Champaign, and all of the projects
involved in the Pew Grant Program in Course Redesign treat the course
not as a "one-off" but as a set of products and services that can be
continuously worked on and improved. Two factors in their design
strategies are key: the collective commitment of all faculty teaching
the course and the capabilities provided by information technology.
Would it be possible for a single professor conducting an online class
to develop such creative, comprehensive, learner-centered designs as
exemplified by the new pacesetters? Perhaps, if the individual spent
most of his or her career working on the class. Would it be possible for
institutions to offer a buffet of learning opportunities to thousands of
students annually without the aid of information technology? Most
certainly not. IT enables best practices to be captured in the form of
interactive Web-based materials and sophisticated course-management
software. Rather than reinventing the wheel at the start of each term,
the new pacesetters can add to, replace, correct, and improve an
ever-growing, ever-improving body of learning materials. This, in turn,
leads to greater possibilities for individualization.
Earlier in
this paper, we commented that the leading institutions described in the
cases do not offer full-blown solutions to the question of how to move
beyond the "no significant difference" phenomenon but instead illustrate
pieces of the puzzle. Because they share a commitment to continuous
quality improvement, all are in an excellent position to incorporate
ideas from others. Already committed to a rolling-cohort strategy, the
University of Phoenix, for example, could enrich its approach by
assessing students’ learning styles, creating cohorts based on those
assessments (either homogeneous or heterogeneous), and designing course
variations to correspond accordingly. Virginia Tech’s math courses and
UIUC’s foreign language courses could incorporate the credit and content
modularization ideas pioneered by Ohio State and Drexel. Groundbreakers
in distance learning, Rio Salado and the British Open University could
learn from the on-campus buffet providers and set new standards of
excellence for off-campus learners. In each case, the systemic approach
of the new providers enables them to incorporate the best of online
academic practice.
This symposium was the fourth of the Pew
Symposia in Learning and Technology. The purpose of this symposia series
is to conduct an ongoing national conversation about issues related to
the intersection of technology and student learning and ways to achieve
this learning cost-effectively. The new providers who participated and
others cited in the paper are creating a new higher education paradigm,
which includes new boundaries for behavior, new guides to action, and
new rules for success. As we continue to develop online courses and
programs, let’s follow their lead, building on the strengths of the
Internet to create new learning environments that surpass traditional
modes of instruction.
