CMS and ePortfolio: At the Crossroads

Course management systems offer powerful support for teaching, but they truncate
student learning at the end of every term. ePortfolios offer a longitudinal
learning environment in which a student can organize and maintain learning connections,
but they may lack the orchestrated vision of an experienced educator. These
alternate structures for capturing, evaluating, and reflecting on student work
should intersect on the student’s desktop to deliver a powerful multiplier
effect to an institution’s eLearning environment.
The CMS has entered the elite ranks of critical infrastructure components,
joining e-mail and payroll as required systems to meet the demands of a majority
of higher education institutions. It is easy to understand why; the CMS provides
indisputable value to the teaching function. A well-designed course
site packages a syllabus, calendar, access to grades, assignment drop boxes,
and perhaps content and class interaction opportunities all in one convenient
place. A faculty member who skillfully uses CMS gains in both efficiency and
effectiveness.
While students generally report that they too value well-designed courses and
course supplements tied to the CMS, they are being shortchanged if the CMS offers
the only gathering place on the eLearning landscape. Course management systems
require that the faculty member owns the learning environment, for it is the
faculty member who must evaluate student work and assign a grade. The learning
objectives, assignment descriptions and goals, faculty comments, and class discourse
disappear from the student’s view as the term, and their course access,
ends. The management structure imposed by the security needs of the CMS encourages
a transmission model of education, whether that philosophy indeed suits the
instructor, or whether the instructor favors a constructivist model of education.
The constructivist model of education is premised on the belief that deep learning
relies on existing structures and knowledge held by individual students. From
varied bases, learning occurs as the student’s knowledge schema assimilates
new information (interrelates it with existing categories of knowledge) or accommodates
(modifies learning schema held by the individual students) to new knowledge.
Educators who ascribe to constructivist principles want to help students learn
how to learn in their own unique ways. Constructivist faculty use CMS assignments
and discussions to encourage students to contextualize and argue from their
own sets of experience; but the results always are time-bound and unavailable
for reinforcement from different classes.
In contrast, ePortfolios offer a marvelous prosthetic for constructivist learning
and can organize the instructor’s teaching outcomes within student-generated
learning categories. Principal components of an ePortfolio system include an
underlying database that supports pre-existing rubrics for contributed content
(sometimes called a scaffold), a repository that holds digital assets (student
work) created by the owner of the ePortfolio, the capacity for the portfolio
creator to build new categories with their own new labels to describe their
work (sometimes referred to as a template), and description and comment fields
for organizing insights tied to the digital assets.
Because the student is the owner and creator of her/his ePortfolio, there is
no need for the work, and faculty and fellow student critiques, to disappear
at the end of the term. Indeed, one of the primary uses cited for ePortfolios
is this support of a student’s lifelong learning, giving the creator a
handy place to document growth and new connections made over a course of study
or career.
It might be illustrative to provide an example of how a student ePortfolio
could help a student bridge and make connections between two courses supported
by a CMS. For the first semester of her freshman year, Katherine enrolls in
Introductory Biology. She is assigned a paper on natural selection, dutifully
surveys the Biology literature, prepares a paper on Darwin’s Origin
of the Species, and deposits it in the assignment drop box of the CMS.
The term ends and this CMS learning environment is locked away from Katherine’s
future review. In her second term, Katherine chooses a course in American History.
The history teacher asks for a critique of the 1925 Scopes Trial, the famous
“Monkey Trial” in which a high school biology teacher was charged
with illegally teaching the theory of evolution. Katherine completes this assignment,
but can only draw on a rapidly receding memory of her biology course. If she
had deposited her Darwin paper in an ePortfolio contextualized by her Biology
teacher’s assessment and her classmate’s discussion, the previous
work would be re-viewable to inform her history assignment. These unforeseen
opportunities for connections multiply over the student’s academic career.
The ePortfolio system encourages this more unified development of student work
because the student decides what to keep and what to discard. The juxtaposition
of diverse works and community commentary suggest connections that might not
be apparent in the linear and segregated record of work that exists in the faculty-owned
CMS. Much like good time management skills, an organized, all-in-one-place,
chronicle of academic work is invaluable to most students.
To deliver on the promise of ePortfolios, several infrastructure/policy requirements
must be in place. The institution must provide students with file space in an
ePortfolio software system. Ideally, both the CMS and ePortfolio system support
WebDAV (drag and drop from the student desktop) and permit single sign-on. Further,
the ePortfolio system needs to be flexible and adaptable to meet many different
learning needs, and in the best of circumstances, if a student moves from one
institution to another, their ePortfolio should travel with them. The Open Source
Portfolio Initiative (http://theospi.org) is pursuing this design philosophy
in their version of ePortfolio. The software is freely downloadable, adaptable,
templates are provided to help scaffold student knowledge, and the software
supports the ability for students to represent and share their work with knowledge
communities of their own choosing.
The CMS has established itself as mission-critical software because it provides
an extremely valuable vehicle in which to organize an instructor’s class,
objectives, assignments, and class discourse. As such, it is more an instrument
of teaching than it is of learning, and it is challenged to facilitate serendipitous
connections that bridge many classes silo-ed in CMS. ePortfolios offer great
functionality to support student-centered learning that emerges over time.
We are currently at a crossroads in eLearning. The appropriate intersection
of CMS and ePortfolio is the student desktop, enriched by intuitive content
creation tools and frictionless WebDAV file-moving protocols. The student’s
work, efforts, and reflections delivered to an instructor within the CMS offers
the student the benefit of an experienced educator helping to guide further
learning. An ePortfolio supports a student’s own learning connections
and unanticipated future needs based on that same work, effort, and reflection.
Forward-looking institutions should support both CMS and ePortfolio and seek
system interoperability to contain costs and provide the best student learning
experience.
