INTRODUCTION
We
are at a critical moment in the evolution of e-learning. After many
years of development, e-learning has become an important business
process for corporations, which are now exploring how to better educate
and manage their employees who rely on fresh knowledge to perform.
E-learning is also at the top of the agenda of public and private
universities, which are looking for ways to extend their influence and
reach new types of customers. And e-learning has attracted the
attention of the investment community as companies have emerged to
capture market opportunities in technology, content, and services.
Despite
all the recent activity, models for how people teach and learn online
are still immature. A new approach could take care of the long-standing
e-learning bugaboos: low enrollments and high attrition rates stemming
from user dissatisfaction. The cause of this problem is the separation
of people in time and space; but it can be overcome by building
environments where people talk to one another, build relationships, and
teach one another.
While there is no simple answer,
there is
one key idea that has been overlooked in the design and implementation
of many of the e-learning programs on the market today:
Learning is fundamentally both social and experiential.
It is the context of the learning—all of the elements that
comprise the
experience around the content—that is most
important.
This paper
will lay out the OTTER Group's model for how best to teach and learn
online. It will look at many of the elements that must be managed to
create e-learning programs where real knowledge is gained, where
communities of learning are created, and where high levels of student
satisfaction are generated.
TOO MUCH CONTENT, TOO LITTLE
CONTEXT
The
emphasis of most e-learning programs to date has been on the
accumulation, organization, and delivery of content. This is manifested
in all aspects of how the new sector has been organized: in the
business and operating models of the service and technology providers;
in the design and organization of the content and learning management
systems that are now widely used; and in the investments venture
capitalists, publishers, universities, and corporations have
made.
With
all of the information now available on the Web, it is possible to find
really good content on just about any subject. And once information
becomes digital, it wants to become free—so much so that MIT
is now
considering making the underlying content of all its 2,000 courses
available on the Internet without charge. In a recent article in
The Chronicle of Higher Education,
MIT's president, Charles Vest, was quoted as saying: “I think we're in
a kind of brief shining moment in general in that the World Wide Web is
making information available to the world for free. I would like to
think that, for at least a brief period of time, we could be a leading
source of higher education on the Web.” According to MIT Civil
Engineering Professor Steven Lerman, MIT can make this content
available free of charge because, “the syllabus and lecture notes are
not an education. The education is what you do with the
materials.”
MIT
is visionary in realizing that it can give away its syllabi and lecture
notes and retain what is of real value: the navigation through these
materials by superb teachers (the pedagogical process); the social
aspect of learning with incredibly smart peers (the learning
community); and the knitting together of content, pedagogy, and
community into a unique learning experience, which is what people are
buying when they step on to the MIT campus.
Former
OTTER
students, even when working with the best professors at Harvard and
MIT, have told us that they value their interaction with one another as
much as they value the content being delivered by their professors.
Thus, the ideal class is organized around what we call the 50/50 rule.
At least 50 percent of the time students spend in the virtual classroom
is spent interacting with and learning about other students. When the
social aspect of the classroom is missing, student dissatisfaction
rises dramatically, as does the attrition rate.
When
we think
about our own learning experiences, we remember not only what we
learned, but how and where we learned. A very large part of the value
we derive from our educational experiences comes socially and
informally—from the context. It comes from the relationships
we build
around the substance of what we are learning. In college, it's the
late-night study sessions, the interesting conversations around the
lunch table, an informal chat during a professor's office hours, the
insights of our classmates in a case study discussion. At conferences,
seminars and off-site meetings it's the networking. The rich context
that we gain from informal, peer-to-peer conversation is often what
helps us make the content more memorable and useful.
In most
e-learning programs offered today, the burden for learning is placed
wholly on the shoulders of the learner. When a learner goes to a course
web site, she enters a grid that does not vary from course to course,
consisting of a menu of activities: announcements, documents,
assignments, external links, communications, and tools. The course is
served up as content that is devoid of any context. She is expected to
navigate this material on her own, without much support. She is offered
email links to faculty and other students, but not much more.
E-learning
should be first and foremost about creating a social space that must be
managed for the teaching and learning needs of the particular group of
people inhabiting that space. This requires a platform that can be
easily modified to take into consideration the needs of the particular
learners in the course. In an optimal arrangement, a student will know
a great deal about his fellow students and faculty before he begins
working through the material. He will be prompted with questions that
have been very carefully designed to encourage him to link the material
he is learning to his own knowledge and experience, as well as
stimulate him to interact with other students and the faculty via email
and chat. This model will use the database underlying the course to
link people and information in new ways that will help him understand
the community of learners he has joined, as well as affect his
relationship with the material itself.
With the
right enabling
technologies, the learner can take advantage of the context in
interesting new ways: if she thinks that someone has posted something
particularly insightful, she can choose to automatically filter out
every posting that individual has contributed to the course. She can
rate her fellow students' postings and emails and have the system mine
the data for the most highly rated information. Even in an online
discussion with thousands of comments posted by hundreds of students,
the most valued information will automatically be recognized by the
professors and read by all of the learners. Such a system also allows
for something that is often overlooked in the e-classroom: recognizing
and acknowledging the most valuable contributors.
PEDAGOGY + CONTENT + COMMUNITY = VALUED
LEARNING EXPERIENCE
When
the focus is no longer content but rather the management of the
learning experience, then the pedagogical process becomes the most
important factor in the design and support of that experience. And that
process is fundamentally idiosyncratic. It's also what makes learning
pleasurable and beautiful. To experience a wonderful teacher's pedagogy
is to be inside her mind.
To be effective, each
course must be
customized both to the pedagogical process of the teacher or
subject-matter expert and to the individual needs of the learner.
Currently, customization of online learning programs often amounts to
changing color schemes or turning features of the platform on or off.
But
customization at a deeper level can mean changing the fundamental
organizing principles of the course space. In a pilot course the OTTER
Group is currently running, we wanted an organization that reflected
the functional tasks of a global securities trader with very little
time. The design was for a small group of people (30) focused on very
specific tasks. Many complex ideas were presented in a linear fashion,
and the students needed to be guided by specific questions. This tight
focus demanded a course environment reflecting that task-oriented need.
To guide students, we made class discussion the most prominent object
on the screen, followed by the group project area. Document
exchange—relatively unimportant for this course–was
placed in the least
prominent spot. We employed simple page designs, making them
task-oriented rather than information-oriented by emphasizing both the
names of the task areas within the course space and deliberately
organizing the functions that were accessible in each of those areas.
Rather than have a “home” page, we made “discussion” the root page of
the class. We also created a directory page called “Who’s
Who” because
we wanted to encourage students to get to know each
other.
The importance of these types of contextual
changes is best illustrated in one of my favorite books of 2000:
The Tipping Point, by Malcolm Gladwell. In his
chapter on “The Stickiness Factor” he explains how the producers of
Sesame Street
made television sticky: “They discovered that by making small but
critical adjustments in how they presented ideas to preschoolers, they
could overcome television’s weakness as a teaching tool and
make what
they had to say memorable. Sesame Street succeeded
because it learned how to make television sticky.”
Gladwell
analyzes two Sesame Street segments to see how the context and
formatting affect learning and retention. One involves the spelling of
the word HUG by a female Muppet. In this segment the
letters HUG are the central feature on the screen.
In a second segment involving the spelling the word
CAT,
Oscar is the central feature. Researchers at Harvard's School of
Education tracked pre-schoolers’ eye movements and found that
the
students focused on the letters in the HUG segment
but on Oscar in the CAT
segment. The kids weren't watching the letters because Oscar was so
interesting: “Oscar was sticky. The lesson wasn't.” This seemingly
small adjustment in the context of how the information was presented
had enormous implications for how much was actually
learned.
In
another example of how to create stickiness, Gladwell cites an
experiment done at Yale in the 1960s on increasing the likelihood that
students would get tetanus shots. It turns out that variations in the
type of information given the students about the dangers of tetanus had
no impact whatsoever on the likelihood of their getting vaccinated.
Only one thing dramatically raised the rates of vaccination from 3 to
28 percent: “including a map of the campus, with the university health
building circled and the times that shots were available clearly
listed.”
Gladwell's analysis of the importance of
contextual and
formatting innovations should be mandatory reading for anyone thinking
about using the Internet as a teaching tool. These small but critical
adjustments in context and format are just as important to the learning
process of global traders as they are to pre-schoolers.
COURSES AS LEARNING
COMMUNITIES
An
enormous amount of lip service has been paid to the creation of
learning communities in the e-learning arena. Most of the services
promoted as communities are really just transactional: fronts for the
sale of content. The truth is that a community is very difficult, if
not impossible, to create from scratch—at least without
enormous
resources (time and/or money) matched with deep social and structural
understanding. It is much easier to recruit and organize an existing
community into a learning community than to start fresh.
Sociologist Amitai Etzioni, in a recent article in
Contemporary Sociology, (http://www.gwu.edu/~ccps/etzioni/A276.html)
defines communities as having the following attributes:
- A web of affect-laden
relationships
among a group of individuals, relationships that often crisscross and
reinforce one another (rather than merely one-on-one or chainlike
individual relationships).
- A measure of commitment
to a set
of shared values, norms, and meanings and a shared history and
identification within a particular culture.
Etzioni
expands this definition to say that communities need not be
territorial: “many ethnic, professional, gay, and other communities are
geographically dispersed.” Also, the bonds that are found within
communities go beyond the instrumental into the realm of
affection. And they are at some level
exclusive.
It
is important to keep these definitions in mind when developing learning
communities. In the OTTER Group’s work with universities, for
example,
we have been most successful when we have drawn upon alumni as the
starting place for marketing and managing e-learning programs. An
alumni group fulfills all of the criteria Etzioni lays out: an
exclusive group whose relationships crisscross and reinforce one
another, by virtue of common cultural experience, with a set of shared
values, norms, and meanings, linked together with bonds of
affection.
In
the early pre-web 1990s, we developed Harvard Business School's first
distance learning program, a seminar via satellite on service
management, marketed to HBS's 50,000 alumni. This proved to be an
extraordinarily successful program, in part because it tapped into the
affiliations and knowledge that were already in place within this
tightly-knit community. First and foremost the learning experience was
very simple to market: we conducted one direct postal mailing to the
HBS alumni list of 50,000. Our extremely high conversion rate of 7,000
participants has only been replicated when we were marketing to
communities of similarly high degrees of affiliation: other alumni
groups and the extremely tightly bound American Library
Association.
For
HBS service management program, only 1 in 6 of the attendees were
actual HBS alumni. The rest were “guests”—colleagues,
employees, and
friends that the alumni had referred of their own accord. The service
management learning experience was extremely well received by this
community of participants, with an overall satisfaction rating of 9 out
of 10. Over 90% of the 7,000 participants said that they would buy
similar e-learning programs from HBS. We would not expect to find such
loyalty among students derived from a random
sample.
In a current
pilot program on the science of persuasion as a social skill, the
learning community begins with the marketing of the course. We are
sending emails to the students who have taken the course and asking
them to go to our web site where they can add comments about how they
have successfully used the material in the course in their personal and
professional lives. Specifically, we are asking them to debunk the
three major misconceptions people have about the mastery of persuasion:
that it is innate and cannot be learned; that it is self-evident and
therefore trivial; and that its practice is unethical.
This
inquiry is intended to reactivate and engage the community of course
alumni who will themselves refer us to interested buyers within their
organizations. Further, the responses of former students will build a
set of multiple points of view about the course to be read by
prospective students. By reading testimonials that are focused on the
alumni’s successful experiences in applying the course
knowledge,
prospective students will have a chance to see the existing community
around the course and imagine themselves fitting into it. The same
process applies to working with corporations: draw from a pool of
people who are already affiliated with one another; make selection for
the course exclusive; and tap into the connecting and selling energy of
managers and sponsors.
To make all of this work, a
new category
of community manager is needed: the Learning Director. For university
programs, Learning Directors are drawn from the alumni of the school or
course. In corporations, they are drawn from the ranks of key managers
and/or the training and education departments. They are trained to act
in the role of what Howard Gardner calls
pedagogistas. Learning
Directors have some knowledge of the content, but their expertise is
really in the context: they understand the personal and organizational
issues around engaging the students. Learning Directors make sure the
students feel connected to the professor, material, and one another.
They highlight student comments that are very insightful or relevant,
and they prod someone who has not spoken up in three weeks.
In
our course on financial technology for global traders, the Learning
Director understands the course materials; he is also a bank insider
who knows how the course is going to be received by the learners. He
knows what will interest them, and how they can apply what they are
learning to their business practices. He acts as a mediator between the
professor and the students. He selects the most relevant of the
professor’s questions to highlight for student discussions.
He also
selects the best comments and ideas to flow back to the professor.
Learning
directors also serve as the beta testers for our pilot programs,
allowing us to create programs that are highly interactive at large
scale. We like to think of them as the Avon Ladies of the knowledge
economy.
PERSONALIZATION
One
of the great advantages of the web is that it can organize information
so that it is personalized to an individual's needs. But today's
e-learning programs are often organized around the needs of the content
providers, not around those of the individual learners: students are
served up homogenized, standardized content “course cartridges” and
“e-packs.” In the physical world, people organize their own notebooks,
choose their study techniques and even pick where they will sit in the
classroom based on their own needs. Personalization is an area where
the power of databases can rival offerings in the physical classroom.
Information can be organized in such a way that learners are given only
what they need when they need it. They also can be given total control
over their learning environments. Meaningful user-controlled
personalization
is something that needs to be incorporated into e-learning design from
the beginning, rather than as a frill or
afterthought.
The Web
offers the ability to create deep profiles of students and use that
information to create personal, unique learning experiences. Profiling
is more than just finding out what skill and information gaps the
students have. It is about understanding the learner’s
context as a
whole human being and shaping the content and course experience
accordingly.
Sophisticated polling methods can be
used to build
a set of independent variables about students that can later be
cross-referenced with questions that deepen their understanding of one
another and the material they are studying. In the OTTER
Group’s course
on persuasion, we have students take a 360-degree evaluation over the
Internet. They assess themselves along several key metrics and then
they have ten people (bosses, spouses, subordinates, clients) assess
them along those same metrics. This assessment is handled anonymously
via email and then collated in a central database on the web. Once
these profiles are built, they can be used as reference points in
teaching case materials.
For instance, because it
turns out
that the buyers of SUVs and Minivans are very different
psychologically, one of the questions we asked students in the
persuasion course is which they’d prefer to buy. According to
an
article in The New York Times, “Sport utility buyers
tend to be
more restless, more sybaritic, less social people who are
‘self-oriented,’ to use the automakers' words, and
who have strong
conscious or subconscious fears of crime. Minivan buyers tend to be
more self-confident and more
‘other-oriented’—more involved with
family, friends and their communities.” The SUV vs. Minivan distinction
proved to be an interesting variable in how groups of students made
decisions about retaining or firing struggling managers in our case
study discussions. In a case in the course, a manager ineptly handled a
politically charged situation with two warring bosses. After reading
the case, students were asked to decide whether the manager should have
been fired or retained. The class was equally divided. Interestingly,
SUV drivers—i.e., those who were more
self-oriented—were more likely to
want her fired than minivan drivers. This exercise ended by asking
students what they thought her job title is today, ten years later.
Most students placed her as either VP of Manufacturing or unemployed.
(She is currently the CEO of Handspring.) Cross-referencing unusual and
compelling personal data not only helped this particular “learning
community” understand itself better, but it also changed the students'
relationship with the material itself by giving them insight into their
own decision-making processes.
The
technology platform that the OTTER Group prefers for our e-learning
programs is both free and open source. It was originally developed by
an MIT computer scientist, Philip Greenspun, to support collaboration
and knowledge-sharing among a community of amateur photographers. It is
worth studying the operation of this true learning community (http://photo.net),
as there are many lessons to be learned there for teaching and learning
online. (It is also worth reading Philip Greenspun's book,
Philip and Alex's Guide to Web Publishing, which can
be read online at http://www.arsdigita.com/books/panda/ or
found at Amazon
or at a local bookstore.) Greenspun first created Photo.net to share
what he knew about photography. He started by writing a 30-page story
about a trip to Berlin and Prague, illustrated with about 60 photos. He
then invited people to contribute their experiences. By simply
including an “add-a-comment” link at the bottom of every article, he
helped users build a great repository of photographic knowledge.
The
company that has built our platform of choice, ArsDigita, was founded
by Greenspun and evolved out of Photo.net. The toolkit upon which the
platform rests, the ArsDigita Community System, places social
interaction and collaboration—the management of the learning
experience—at the center not only of its design, but also of
its
operating philosophy. One of the great strengths of the open source
software movement and the reason that it yields superior
programs—programs that reflect the specific needs of the
communities of
people and individuals who are using the software–is that you
have
access to a large community of developers with many ideas. With closed
source software, you only have as many ideas as the group of people who
created the program generates or as their lawyers will allow.
For
example, the next version of the ArsDigita software will contain chat
protocol that is written with academic exchange and collaboration in
mind: chat postings can be threaded as they are posted so that inquiry
and answers between students and professors can be well documented.
Automatic transcripts of chats are generated that can be organized by
time and by thread. Because the software is open source, this kind of
enhancement can be readily added to the functionality of the platform
by any of the many people working on the system, and this best practice
of archiving threaded chat can then be used freely by others.
As more users adopt the software and adapt it for
their specific needs, the best practices in e-learning will be shared
by getting built into the software itself. In
the past year, the ArsDigita Community System has been developed as a
content and learning management system, now called ACES (the ArsDigita
Community Education System). You can read the case study about its use
at MIT's Sloan School of Management, as well as download the software,
at: http://www.arsdigita.com/customers/casestudies/mit.
We
believe open source to be the best technology strategy for the
development of shared knowledge and learning. In a recently published
book on the open source software movement, Rebel Code: Inside
Linux and the Open Source Revolution,
author Glyn Moody talks about the values that have driven the
development of the Internet: “as the Internet moves closer to the heart
of the modern world, it inevitably carries with it the free programs
that drive it, and seeds the values that led to their creation.
Its
basic code of openness, sharing and cooperation is starting to spread
outside the confines of one or two high-tech industries.”
We
believe that the code of openness, sharing, and cooperation that is at
the heart of the e-learning process is also at the heart of successful
academic institutions and corporations. At OTTER, openness is a pivotal
part of our company's technology and operating strategies and value
system. Sharing knowledge and ideas is one of the
great joys of
being human. We take advantage of that phenomenon in our course design.
We pay careful attention to it in the technology platform we choose. We
have the most meaningful jobs in the world: we connect
people–including
some of the world’s great teachers–across time and
space to share
ideas, knowledge, and wisdom so that they can teach and learn from one
another. And we learn so much in the
process.
