Towards
a Global Platform for Knowledge Exchange: Forward Links and Microcredits in
Learning Environments
A
Proposal by Bruce McHenry (bmchenry@alum.mit.edu)
What’s
Missing in OpenCourseWare?
MIT’s
OpenCourseWare (OCW) initiative will broadcast the equivalent of a good
students’ course binders containing the syllabus, course notes, quizzes with
answers and exams. This material
will be static and principally be of use to other teachers designing their
courses. OCW does not address the
fundamental inefficiency of having thousands of instructors design separate
courses about essentially the same topics.
It would be far better to have signature courses which have well
defined learning objectives and requirements for credit.
The Internet, which makes it possible to bridge time and space, creates
the theoretical possibility of delivering courses globally.
But realizing this will require the transformation of education, from
what is essentially still a cottage industry into a much more organized and
integrated system. A
Platform for Knowledge Centers
Franchises,
which require a buy-in from partners and pool certain resouces, provide one
model for organizing education. Each
franchise may be built around a body of knowledge, and leading teacher-authors
will have an opportunity to create and operate the knowledge centers; it is to
these individuals that benefits will accrue.
The MIT Media Lab, by virtue of its name, mission, and a preponderance
of research on interactive experiences, could also participate by taking a
role in defining the next generation platform for the operation of such
knowledge centers. MIT
could also lead a buyer’s coalition by teaming up with procurers at other
leading universities, and probably also the Department of Defense.
As the single most largest client, the DoD has been able to galvanize
the industry by requiring compliance with the SCORM standard (packaging and
certification within learning modules). A
Middle Approach Between Open and Closed Source
The
degree of proprietary control is a key variable for both the suppliers and
buyers of the platform. A knowledge exchange exchange system will have strong
network effects - its value increases strongly with the number of users, and
so does the potential for locking in customers, as with MS Windows.
The alternate approach, typified by other layers of Internet protocols
such as TCP/IP and HTML, is to make the standards non-proprietary.
MIT
could develop a middle road with vendors, in which the following are carefully
negotiated: 1) the length of time that the source code remains completely
closed and proprietary, 2) the availabilty of source code to certain trusted
groups. The model would be
inspired by the open Linux development process: a) there would be many
separate components, b) each component will have its own development leader
and internal contribution system. Extending
the Linux approach, each component could have a licensing agreement with
timetables for opening the source code, and an ownership stucture based on
negotiations between the development leader and the contributors.
This
seemingly complicated structure would help the software industry to mature and
develop a less closed form, with programming teams being able to work
independently and add value where they are best able to do so.
Revenues would be realilzed during the closed period, and decline to
near zero as the deadline approaches for opening the software.
But so long as project leaders continue to respond to the almost
certain demands to maintain and improve their code, they will control the
releases of new versions having later opening dates, and continue to benefit
from multiple sales of their new work. However,
the opening dates guarantee that clients will not be indefinitely locked in if
a component developer becomes incompetent or unresponsive. The
Next Layer
The
next layer must build upon standards, such as for OKI/OCW, SCORM etc.
It will be concerned with how the learning environment is managed: who
interacts with whom and how, whether the interactions are recorded, reused and
refined, and crucially: how people are motivated to contribute to and improve
the quality of the centers of knowledge. This
layer should instantiate the recurring vision of a knowledge network that
works more like the brain itself, where new ideas integrate with and modify
pre-existing thought. The
original representations on the network must be open to change - not by
anybody at any time, but through a carefully managed process.
Allowing changes and negotiating their value will be intrinsic, and
depend on enabling technologies, such as “forward linking” and “microcrediting”. WWW
links must be valid when the page is written, and so necessarily point
backward in time. Forward links,
on the other hand, would be allowed on a page after it is posted.
They are a kind of annotation, but would be much more if also
integrated with microcredits. The
credits will serve to motivate, and negotiation over their value would inform
the selection process. In a
learning environment, credits could contribute towards raising the final
grade. But microcredits could
also represent ownership with present and future payments.
Credits could apply to revisions distributed widely and with
substantial aggregated value. Although
the price of the OpenCourseWare materials will be zero, learning environments
built upon such materials already contribute to student satisfaction, will
have increasing real value, and eventually be funded out of tuition. The
Next Initiative
The
process of opening up the learning environments will likely proceed in a
series of small steps, following opportunites as they arise.
It is difficult to predict these in advance, but it is timely to
support the development of a well documented, major proposal to develop and
deploy a next-generation platform. The
platform would include features such as (the actual specification will be set
by a relatively small working group of experts and checked off by
participating teacher-authors): Ø
forward
linking Ø
credits,
and reputation building on the same Ø
real-time
interactions with matching of the participants Ø
recording,
refinement and re-use of the interactions Ø
progressive
revelation of questions and answers Ø
ability
to raise and resolve disagreements The
courses would ideally be taught at several places – including
cross-registration at a couple of other leading schools to start – and
include learners off-campus who are neither enrolled in a degree program, nor
even expected to complete the whole course.
The
proposal’s budget would provide for: Ø
Faculty
time to develop the courses Ø
Compensation
set aside for significant emergent contributors Ø
Procurement
of the platform Ø
Staff
to negotiate terms with the vendor(s) and write the proposal in coordination
with faculty principal investigators MIT
could establish an appointment to begin the work for this project.
The appointee should have approval from the Provost and President, and
be allowed access to relevent meetings, such as those held by CEP, OCW, OKI,
AMPS and Sloan.
