"Learner Contributions to Knowledge, Community, and
Learning"

Effective knowledge workers need to develop new higher-level
skills for accessing, selecting, manipulating, and representing
information in a variety of formats.
We are facing the challenge of large-scale knowledge production.
The SCANS report says, "Modern work is just too complex for a
small cadre of managers to possess all the answers" (SCANS
1992, p. 16). Workers at every stage or level of a knowledge-based
organization must contribute to the production of knowledge.
"A learning organization is an organization in which people
at all levels are, collectively, continually enhancing their
capacity to create things they really want to create" (Senge,
as quoted in O'Neil 1995, p. 20).
If children and teachers are engaged, collaboratively, in
actively constructing their own knowledge, then schools are laying a
foundation for the intellectual development of the knowledge worker
(cf. Goldberg and Richards 1995).
In the Global Lab project organized by TERC, teachers, high
school students, and research scientists around the world study
local and global ecological change. They use low-cost instruments
and sensors such as ozonometers, ion-selective probes for soil and
water monitoring, and field data loggers.
Such networked educational projects sometimes have direct and
concrete benefits to the local school and neighborhood. One example
is the series of air quality studies conducted by Global Lab
students in Pease Middle School in San Antonio, Texas, which
resulted in improvements to the ventilation system of the school and
a new appreciation by parents and administrators of the
contributions their young people can make (Berenfeld 1993).
Responsibility for one's learning will be shared by all. The pace
of change is too fast for individuals to depend totally on others to
structure their learning and information for them; ...new curriculum
frameworks, instructional materials, assessment and testing schemes,
and teacher training programs will take into account these increased
responsibilities for information management and knowledge creation.
Responsibility for teaching and mentoring will be shared more
widely than in the past.
Classroom teachers will not be expected to have expertise in all
the areas of knowledge their students are encountering.
Learning is seen more as a process. Intelligence is recognized as
diversified, and authentic assessment tells us to look at it in
context. Teachers and administrators are also learners. In that role
they are typical learning organization managers. They are mentors;
they guide, provide access to resources, facilitate.
The Evolution of Learning Devices:
Smart Objects, Information Infrastructures, and Shared Synthetic
Environments

Over the course of the industrial revolution, motors shrank in
size and cost, disappearing inside household appliances and
workplace tools to create new kinds of machines. Through a similar
process, we are now embedding computers and telecommunications into
our everyday context, making possible three innovative types of
learning devices. Smart objects, with embedded microprocessors and
wireless networking, explain their own functioning and help us
create "articulate" educational environments that
communicate with their inhabitants.
The coming generation of computers and telecommunications is
different from prior evolutions of information technology because it
is dramatically reversing the century-old trend toward a crowded
ecology of devices. Different species are fusing together; the
radio, television, telephone, copier, fax, scanner, printer, and
computer will eventually coexist in a single box. Soon, the ecology
of information technologies will have only a few superspecies
remaining that synthesize and extend the capabilities of all current
devices.
Global information infrastructures ... are ... extending our
nervous systems so that we can communicate and learn across barriers
of distance and time, exploring and contributing to virtual think
tanks (Dede 1994). As a result, the means for creating, delivering,
and using information in business, government, and society are
swiftly changing. To successfully prepare students as workers and
citizens, educators must incorporate experiences into the curriculum
that enable students to create and utilize new forms of expression
and that can be activated just in time, at any place, and on demand
(Dede and Lewis 1995).
The "information superhighway" ... is an inadequate
analogy. Backward-looking metaphors focus on what we can automate
but miss the true innovation: redefining how we communicate and
educate by using new types of messages and experiences to be more
effective. Since emerging forms of representation, such as
hypermedia and virtual reality, are in their early stages of
development, we are just beginning to understand how they shape not
only their messages, but also their users.
The core skill needed in today's workplace is not foraging for
data, but filtering a plethora of incoming information. The emerging
literacy we all must master requires immersing ourselves in a sea of
information and harvesting patterns of knowledge, just as fish
extract oxygen from water via their gills. In this environment,
educators must understand how to structure learning experiences that
make this kind of immersion possible. Preparing students for full
participation in 21st century society will require expanding the
traditional definitions of literacy and rhetoric to encompass "immersionlike"
experiences of interacting with information.
Another type of emerging electronic environment is the virtual
exhibit that duplicates museums and other real-world settings.
Virtual exhibits make possible a wide variety of experiences without
the necessity of travel or scheduling.
Teachers must provide unsophisticated learners with educational
experiences that enable them to construct their own knowledge and
make sense of massive, incomplete, and inconsistent information
sources. In order to create a learner-centered environment in which
students can take full advantage of information infrastructures, it
is vital that educators augment the traditional curriculum with
collaborative, learning-through-doing activities based on linked,
online materials and orchestrated across classrooms, workplaces,
homes, and community settings.
Virtual communities that provide support from people who share
common joys and trials are a second means for enhancing student
learning through information infrastructures. ...This alternative
conception of authenticity may reflect a different kind of learning
style than the visual, auditory, symbolic, and kinesthetic
distinctions now used.
Virtual communities can help bring about close cooperation and
shared responsibility for learning among all the educational agents
of society families, social service agencies, workplaces, mass
media, schools, and higher education. For example, involving
families more deeply in their children's education may be the single
most powerful lever for improved learning outcomes.
Since video game consoles are widely found even in poor and rural
households, they offer a promising installed base of learning
technologies if we develop educationally rich material that takes
advantage of these systems.
Educators must help all students become adept at distanced
interaction, for skills of gathering information from remote sources
and of collaboration with dispersed team members are as central to
the future American workplace as learning to perform structured
tasks quickly was to the industrial revolution. Also, by increasing
the diversity of human resources available to students, distributed
learning can enhance equity and pluralism, while preparing young
people to compete in the world marketplace. Virtual classrooms have
a wider spectrum of peers with whom learners can collaborate than
any local region can offer and a broader range of teachers and
mentors than any single educational institution can afford.
Today's "couch potatoes," vicariously living in the
fantasy world of television, could become tomorrow's "couch
funguses," immersed as protagonists in 3-D soap operas while
the real world deteriorates. The most significant influence on the
evolution of education will not be the technical development of more
powerful devices, but the professional development of wise
designers, teachers, and learners.
Digital Technology and its Impact on Education

So what is the difference between the past two decades of
computers and Internet access and the present, since even now WWW
access requires computers and an Internet connection? The difference
is that the Web represents Information, and information cannot be
disregarded the way that computers can be ignored. Teachers cannot
choose to ignore or have their students omit available information
on any subject when the goal is for them to learn. A revolution is
taking place in education.
In fact, the idea of a browser needs to give way to the more
encompassing idea of a Web environment that is flexible and dynamic
and can be customized to the needs of the moment. Java, a new
programming language from Sun Microsystems, opens up these
possibilities by allowing programs to be sent over the Web in a
secure fashion. Programs that are executed locally when they arrive
at the user's desktop are an example of "mobile code."
The availability of additional bandwidth through, say, cable TV
Internet access, would be of obvious value in enhancing real-time
collaborations, especially those involving huge data sets, high
speed visualization, and real-time video.
This technology is moving toward fully digital conferencing
techniques that go beyond video and encompass a completely rendered,
customizable, bandwidth-sensitive, 3-D representation of each
participant, in a fully 3-D environment for the conference and any
accompanying data or simulation results.
Some of the current tools include a Web-based group calendar,
chatting capability, capability for threaded discussion and group
meetings, writing tools, document storage and publication tools, a
project management tool, a forms tool, workspace management tools,
and more. New asynchronous tools are currently under development,
and the synchronous tools being developed through the Habanero
effort will become features of this workplace very soon.
An obstacle that needs to be overcome is the view many hold that
computers and Internet connectivity are "tools" for
learning, and thus an increased grade point average is the only
measure of value for these resources. A more important perspective
is for administrators and school boards to realize that the Web
represents a new environment for learning and teaching and that very
soon every teacher and student will need access to the information
represented on the Web in order to be competitive in their work and
in their lives.

Networking Universally Available"

Commercial networks emphasize privacy and security issues over
cost and access considerations. For educational and community
networks, cost and access are the primary concerns, and network
architectures that neglect these factors are unlikely to be
sustainable for very long.
But one must bear in mind that maintenance costs for wireless
links are likely to be higher than those for fixed wiring and that
the bandwidth available for wireless communications is extremely
limited compared to the bandwidth of fixed copper or fiber
infrastructure.
Local aggregation of traffic. School districts can aggregate
traffic and purchase bulk connectivity to pass this traffic to the
Internet cloud. Municipal governments can play a similar role for
community centers and government offices. These groups assume a
portion of the responsibility for network management and thereby
reduce costs for the end users.
Advances are also being made in the area of Web editors, which
simplify the task of creating resources to be placed online via the
World Wide Web. These advances are reducing the costs of training
students and teachers to create multimedia presentations for online
distribution and increasing their ability to develop these resources
as part of their standard classroom activities.
Connecting the Connectivity and the Component Revolutions to Deep
Curriculum Reform

Rapidly emerging industry systems and standards, such as OpenDoc
and OLE, solve many of the technical problems described above. The
basic idea is as follows. Large, stand-alone software systems will
give way to relatively small, interoperable components that can be
produced independently of one another, include their data in common
file structures (such as a single notebook of the type described in
the scenario), and share screen space and control.
Many more producers can participate in the market at a component
level, and schools can purchase and assemble what they need from a
wide variety of components, upgrading piecewise as needed over time.
This fits the fluidity and adaptability depicted in the scenario,
which contrasts starkly with the slow change of most schools and
system

The network can reach handhelds through a simple serial wire,
infrared, or wireless digital radio and turn them into Internet
clients and servers. With this capacity, a student can hold the
entire cyberspace infosphere. There is no need to possess hard
drives for on-board personal files, no need to squeeze in an
encyclopedia or huge databases, no need to have computational
muscle; these capacities can exist at a remote server.
Soon there will be schools where all students have their own
networked computer that they can use year in and year out, at home,
in school, on the bus, on vacation, and in the family car. For these
students, education, especially science education, can be much
richer and more interesting and meaningful. Networking will soon
make these new uses possible with affordable handhelds, rendering
these computers far more useful than they would be without
connectivity.
Over the next decade, handheld computers will change a great
deal, so it is unreasonable to use the current models as a guide.
Wide bandwidth digital networks--pipes--will reach into every
home and school in a decade, whether the data is moved over the
power line, cable, telephone, satellite dish, fiber, or dedicated
digital line. In homes, these pipes will terminate in a server
computer that might called a set-top box because a TV will be
connected to it. But the server will do much more than simply
provide a TV signal; it will also provide network access to all the
computers in the home, including the kids' handheld computers, using
wireless, infrared, and wires. Schools will also have ubiquitous
networking, so that no student will need to carry files in a
handheld computer, but can have full access at home and in school.
Synchronous and asynchronous communication among students locally
and worldwide--using combinations of speech, text, drawings, and
pictures--will be commonplace. Two-way video will be expensive and
less used outside business, because of the demands it makes on
bandwidth and simultaneity. The most common piece of software will
be client network tools descended from today's browsers, that
integrate access, authoring, and application control. The huge
market for these tools will ensure interoperability between
platforms and networks, creating a network as seamless and
transparent as the current telephone network.
There will be an explosion of network-based courses for teacher
professional development. The best of these will offer world-class
learning o
A profusion of netcourses will be available to students, ranging
from little more than organized tours of network resources to
sophisticated courses offered by scientific and educational experts.
Some will be free, while others will charge tuition.
Information technologies will support a full integration of
experimental science with mathematics in beginning student projects
and investigations. Starting at 6 years old, kids will be designing
and carrying out their own technology-rich investigations, gaining
experience with materials, design techniques, measurement, error
analysis, and interpretation.
Because of the skills and knowledge covered by the elementary
curriculum, mathematics at the middle levels (starting with kids 13
to 15 years old) will be freed from much of the beginning algebra
abstractions and instead will concentrate on numerical modeling,
estimation and, later, the use of algebraic formalism, particularly
with the help of graphers and symbolic manipulators.
The concentration on modeling, particularly dynamic modeling,
will provide a key underpinning for a range of scientific
theorizing, since dynamic models with feedback help students predict
the future of everything from astronomy to the stock market, from
global warming to school demographics.
"Renewing the Progressive Contract with Posterity: On the
Social Construction of Digital Learning Communities"
Robert McClintock, Institute for Learning Technologies, Teachers

First, people are converting all the contents of all the world's
cultures to digital form, making the results available to any person
at any place at any time. Second, people are gaining flexible
command of multiple ways to represent information, simulate
interactions, and express ideas, extending the reach of
intelligence, altering the spectrum of civilized achievement, and
lowering thresholds to cultural participation. Third, people are
externalizing diverse basic skills--to calculate, spell, remember,
visualize, compare, select--into the digital tools with which they
work, making practical mastery of such skills, once an outcome of
education, increasingly a given at its outset. As these changes
become evident in practice all around, educators sense that the
spectrum of pedagogical possibility alters significantly.
New media alter the ways of knowing and the opportunities for
participating in the creation of knowledge. Multimedia, and its
extension in virtual reality, is not merely a glitzy vehicle for
edutainment hype. It is an epistemologically interesting development
in our culture.
In deciding what to do with changing conditions, educators will
engage in the social construction of a new educational system, one
that will come about through diverse innovations undertaken here and
there by people and groups that share, to varying degrees, a common
understanding of what potentialities arise in their world of
practice with the new technologies.
We can do better in our extended present by recognizing that the
task facing educators is to reconstruct the whole system in ways
that will allow it to use new communications resources to overcome
the inherent, structural deficiencies of the current system.
People, acting in the face of uncertainty, must determine what
they can make of these emerging possibilities. Many groups and
interests, pursuing many divergent inspirations, are vying for
command, and a kaleidoscope of coalitions establishes, through
diverse initiatives, emerging norms of practice.
