Summary

The nature of work and learning in our knowledge-based society and economy requires active participation by individuals and groups in the construction of knowledge. Active construction of knowledge, participation in collaborative learning, and building on learners' interests and experiences outside of school are major threads in educational reform and new curriculum standards. In this paper, we will provide examples of student work that not only demonstrates their own learning as young "knowledge" workers, but also makes a contribution to their community, to the learning of others, and to the base of knowledge available on the Internet. We will construct a brief vision of learning, teaching, and knowledge building in the future that assumes broad participation in these activities.

I. Introduction

Kris Abel, then a ninth grader at Patch American High School in Stuttgart, Germany, attended the D-Day Commemoration Ceremony at Patch Barracks on May 26, 1994, with his grandmother Ms. Vernell Tanner, widow of a World War II veteran. Kris shared his first-hand experience in this historic and personal event with people across the world through his school's World Wide Web server, with the help of teacher Pat Ridge. In his essay Kris says:

The appearance of the many veterans and their wives was one of the main attractions for me and my grandmother . . . They helped to personalize the event and make it official. With their solemn presence, the goals of the WW II Commemorative Command Program were achieved . . . From a personal perspective, I am proud to be related to a widow of a WW II veteran. My grandmother has been one of the great things that has helped me to understand the war pains of the countries involved in the war effort, and has given me even greater respect for the soldiers and their FAMILIES that experienced and paid the high price of war . . . I was the only one in the room under twenty and my grandmother was the oldest, so we attracted the attention of many . . . For the sake of the rest of us, D-Day + 50 must not be the end of the commemorative efforts of the world. Instead, it should be just the beginning of our respect and pride for the countries that were willing to risk a generation. We must show that their courage was not in vain, and that we understand the cost of our most deadly game.

-- Kris Abel

On June 1, 1994, Patch American High School's exhibit, "D-Day: The World Remembers," was announced on the National Center for Supercomputing Applications (NCSA) "What's New Page." In the following four months, more than 77,000 "visits" to its Web server were registered. The visitors represented people from 39 countries on the globe (ranging from Taiwan, to Russia, to Israel, to South Africa, to New Zealand, to Brazil, to the United States). The D-Day exhibit comprises work from a variety of sources, such as articles from Stars and Stripes, invasion maps from Department of Defense historians, newsreels of the landing, and speeches from Churchill and Truman. The main exhibits, however, are student and teacher essays and photos on the topics of D-Day and World War II. This exhibit continues to attract visitors and researchers from around the world. Click here to see a sample of the following materials.

Like children (and learners of all ages) in many different places in the world today, the students at Patch American High School are seeing their unique local resources in a new light because they now have a worldwide audience for their work. They have the opportunity to create new knowledge and understandings by bringing their own unique perspective to local phenomena and information.

II. Schools as Learning Organizations in a Knowledge-Based Society

Once the principal source of wealth was natural resources. Then it was mass production. Today it is clearly the problem-solving capacity of the human mind--making products and tailoring services to the needs of people all across the globe.

--President Clinton, February 1994 speech to the American Council on Education

The changing nature of the world's economic system--the shift from an industry- based society to an information-based society--is a pervasive factor driving educational changes for people of all ages. Society is shifting to the application of knowledge as the primary means of raising productivity. Phillip Schlechty (1990) argues, "In an information-based society, knowledge work is the primary mode of work, since information provides the primary means by which work is accomplished" (p. 35). This presents qualitatively different challenges to traditional companies. Innovative companies are responding to these challenges by transforming, in Peter Senge's terms, into "learning organizations":

. . . organizations where people continually expand their capacity to create the results they truly desire, where new and expansive patterns of thinking are nurtured, where collective aspiration is set free, and where people are continually learning how to learn together (Senge 1990, p. 3).

Effective knowledge workers need to develop new higher-level skills for accessing, selecting, manipulating, and representing information in a variety of formats. But this alone is not sufficient. As George Leonard said in 1968, "The highly technological, regenerative society now emerging will require something akin to mass genius, mass creativity, and lifelong learning" (Leonard 1968).

That vision of a quarter-century ago is now reality. We are facing the challenge of large-scale knowledge production. The report of the Secretary's Commission on Achieving Necessary Skills (SCANS) 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).

Schools, in turn, can respond to this challenge by taking seriously the constructivist approach to learning. 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. We can then extend the metaphor of a learning organization to the school system (cf. Goldberg and Richards 1995).

----------------------------------------------------------------

III. Creating Knowledge in Networked Communities

In this section we explore examples of students and teachers contributing to the National Information Infrastructure (NII) by producing authentic products that represent their growing skills and knowledge.

A. Distributed Collaborative Inquiry

Collaborative inquiry in networked communities (Hunter 1993b) is a genre of learning, teaching, and knowledge-creating activity that illustrates many elements of educational reform and the knowledge-based society. Students in schools around the nation and the world gather data from their local environments, such as acidity of their rain water, quality of the indoor air, ozone levels, water quality in rivers and streams, biological indicators of changes in climate or pollution, effects of ultraviolet light on plant and animal life, species diversity, wildlife populations, and migration patterns. They work in teams, often engaging parents and other local community members (such as scientists or engineers from a local water department) in their investigations. Each team is also part of a virtual community of scientists, students, and teachers in other schools. Each school contributes to a collective database that includes information from many different geographic locations. Through the networks, the students work together to aggregate, analyze, and interpret the data and share their discoveries and interpretations. The large database gives students the opportunity to recognize geographic patterns in the data and provides a basis for comparing local data with data from other locations; data gathered locally now have more value because it is shared with a geographically distributed community.

There are hundreds of such collaborative inquiry projects and communities organized by teachers, experts, and students. Such projects help students move between the concrete, physical world they can touch and measure, and the electronic world of data they analyze to make and communicate powerful abstractions--exactly the kind of workers Reich (1991) characterizes as "symbolic analysts." By learning to observe and describe their local physical and social world in ways useful to people in other locations, they learn to create knowledge, a role that in earlier times was enjoyed by only the small minority of scientists, inventors, writers, industrialists, or statesmen.

In these kinds of collaborative inquiry communities, the learner has a real and responsive audience. This is highly motivating, just as it is motivating to any professional to get feedback from colleagues or audiences. The beneficial effects of this motivational aspect on learning have been studied in a systematic way by educational researchers, including Margaret Riel, who has studied children's writing (Riel 1990), and Nancy Songer, who is studying children's learning about weather and climate (Songer 1994).

Global Lab

Over the past several years, teachers and researchers have begun developing tools and standard methods that help make virtual communities more productive. 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. To make meaningful scientific comparisons with sites from around the world, students and teachers must ensure that all factors influencing measurements are identical; when students in Moscow and Boston establish uniform guidelines to compare data, they learn the rigors and excitement of research. Students learn to investigate trends, compare their findings with local regulations and standards, and report and analyze data. The use of common instruments and software helps establish a common basis for collaboration. A peer review system, access to scientists for online assistance, and participation in collaborative research groups help develop quality research projects. Much work needs to be done in establishing mechanisms for maintaining quality of the knowledge produced.

Project GLOBE

Because they are located all over the world, schoolchildren can often monitor many more sites for environmental studies than the professional scientific community could support. This is the basic idea of the GLOBE project initiated by Vice President Gore. Eventually, when large numbers of students and teachers have the appropriate tools, skills, and network participation, they will fill an important role in areas such as monitoring atmospheric ozone, ultraviolet light, water pollution, soil pollution, and bioindicators of global, regional, and local change. The economic value of students' work has already been recognized by some of the companies that produce instruments and sensors. These companies value data collected in diverse circumstances and locations for testing their products; the companies provide the products to the community at reduced prices.

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).

In Ann Arbor, Michigan, school children's data on water quality have been of such utility to the town that banks and the Chamber of Commerce have established low- cost loans for parents to purchase computers for children, and companies are offering jobs for students to earn their own computers.

B. Systems Thinking

At Gonzaga High School in Washington D.C., students and their teachers are creating an Internet World Wide Web server on the subject of earth system science. Students use systems modeling software (STELLA II), data visualization tools (NCSA Image and NCSA Collage), and data from NASA databases to research earth system science topics. In each project, the students conduct background research, create hypotheses, develop a strategy for data search, investigation, and testing, model the system qualitatively and quantitatively, and communicate their findings through a hypermedia document using NCSA Mosaic on the Internet. The teachers, Mike Keeler and Farzad Mahootian, are collaborating with teachers in other D.C. schools to form an exchange of such models and course materials through their Internet server.

C. Today's Students--Tomorrow's Citizens

If Chris Tanski and Seth Ladd are examples of tomorrow's workers, we all need to wake up and take notice.

Both are high school students who have already been working to develop educational programs and materials for use by learners anywhere in the world. With some support from BOCES staff, and with multiple talents already in their possession, these young students have exemplified what happens when motivation and opportunity converge.

Chris Tanski

When eighth grader Chris Tanski first approached the Central New York Regional Information Center (CNYRIC) for an electronic mail account in 1993, he was supported by Mr. Kieran O'Connor, then his social studies teacher, now a CNYRIC systems consultant. Chris used his assigned e-mail address to access and maintain discussions on topics such as golf and skiing. As he probed the local e-mail system, the programming staff who had not encountered a motivated student on this system were worried. But their worry was unfounded. By tenth grade, Chris used his knowledge to move on to become a software developer with a local Cortland City company and, more importantly, a developer of Internet-delivered resources on a computer maintained by NASA to support learners across the world. As his skills developed, BOCES staff passed information along to Vicki Dick, Cortland's microcomputer support contact, about a national award for exemplary students. Chris was nominated by Vicki and selected as the winner of the high school division of the 1995 Technology Leaders Competition. In June 1995, he returned to Cortland with a new Compaq portable computer, after having addressed several thousand educators at the 1995 National Educational Computing Conference in Baltimore. (Contact Dan Lake about a video of Chris's speech.)

Chris has now moved to Pittsford, New York, where he is working on "Quest," NASA's K-12 Internet project. There Chris has spent the entire summer implementing the advanced interactive features of the NASA server. "Quest" has several purposes: to help schools and teachers connect to the Internet; to point to useful resources and information; and to assist teachers integrating the Internet into their classroom to support restructured math and science learning. Steve Hodas of NASA (hodas@nsipo.nasa.gov) commented, "We would like to connect teachers with NASA projects so that kids can see what real scientists do!"

Seth Ladd

When eleventh grader Seth Ladd was asked by his art teacher, Bob von Hunke, to join a team formed by Dan Lake to create a unique community resource to share with the world, he readily agreed. With the information from Bob von Hunke's computer- based ceramics curriculum, and with information supplied by the Everson Museum in Syracuse, New York, Seth and a team of students from the Fayetteville-Manlius High School Computer Graphics Club proceeded to create a resource available to anyone in the world studying ceramic objects and teaching how to create with clay. Called "ClayNet," this project is a model for the dissemination by teacher-student-community member teams of local resources that help represent this community's cultural pride. (EdNote: this site has evolved into Ceramics Today.)

Using the opportunity and knowledge gained from this endeavor, Seth has formed his own consulting enterprise. He produces Web pages for area small businesses so that they may advertise on the Internet. He is also working during the summer to help automate some of the BOCES registration procedures used by teachers to subscribe to workshops held by the CNYRIC Learning Technologies Department. In the fall, he will continue adding Everson imagery to the F-M ClayNet project as part of an independent study effort working with other students.

Chris and Seth are prime examples of the idea that learning and work may be integrated into a profitable enterprise by motivated students. All they need are support and opportunity provided by their teachers--and in these two cases, support from OCM BOCES support staff working to create productive learning environments in our community.

D. Juneau, Alaska--Dzantik'i Heeni Middle School

Juneau, Alaska, has been networking all the schools in the district over the past year. The district-wide network is used in the schools to restructure the curriculum and meet the new Alaska standards. Collaboration is underway with the University of Alaska on a new Masters in Teaching program. The Dzantik'i Heeni Middle School is a Co- NECT demonstration site. The BBN Co-NECT design is a model for whole school change incorporating project-centered learning, portfolio assessment, cluster-based management, and, underlying and supporting this, a technological infrastructure.

To support the cultural diversity of its students, Dzantik'i Heeni Middle School has an enduring theme celebrating diversity and invites community participation for one month of the year. The Dzantik'i Heeni Web server describes the schools, community, and school projects, including one where students are developing interpretive guides for two popular trails in the Juneau area and another called Alaska Online that is the product of an ongoing curriculum project. The story below is about the Dzantik'i Heeni Middle School's work on the Alaska Online project.

My grade eight students and I quickly entered the technology revolution last school year. Together we crafted a project we call "Alaska Online." The project goal is to educate people about our great state by publishing useful information on the World Wide Web.

As our project grew, students developed working relationships with many community, state, and federal organizations. They became keenly aware that Alaska Online was very different from their previous classroom experiences. They clearly understood that our classroom was making a valuable contribution to the global computer network.

Throughout the project students faced and overcame many challenges. Many of these students were at risk, lacked writing skills, and had lost pride in their community. In many ways this project helped them overcome these problems. Getting involved, learning about their community, taking on the responsibility of working with professionals in the Alaskan federal agencies, all gave them a sense of ownership, awareness of their abilities, and pride. One challenge was to fill the role of a professional writer. I recall the day a student asked me, "Do I really have to rewrite this piece again?" My response was, when we write for a potential audience of 30 million people, we don't want to spell things incorrectly. He smiled and went to draft another paper.

IV. Foundation for Participation

The following characteristics of active learning provide a foundation for a participatory vision of education:

Creating this kind of foundation will be a collaborative effort or partnership among administrators, university faculty members, community, business, labor, and political leaders, as well as parents, teachers, and students.

The central value of internetworking to support learning and teaching for our changing world is that internetworking can support or enable authentic learning experiences and cross-institutional collaborations needed for the reform of education (Hunter 1993a). When learners and teachers contribute to the information infrastructure by participating in virtual communities and by setting up information services on the networks, their experience has many of the visionary qualities summarized above. The key characteristic of internetworking that enables this kind of experience is that the people who use the Internet are creating and exchanging knowledge, rather than passively receiving someone else's information. There is a danger that the networks could be used to transmit and amplify traditional and outmoded elements of schooling instead of providing a mechanism for the transformation to lifelong learning needed by all citizens. Many well-intentioned efforts to apply technologies to schooling (often in the name of "reform") still assume such factory-era constraints as segregation of learners by age, a sequential curriculum, an emphasis on everyone learning the same thing at the same time, learning activities confined to the school or classroom, no participation of parents in the learning activities of their children, knowledge predigested by experts, teacher as authoritative knowledge base, memorization of facts today for use in later years, subjects isolated by disciplines, same roles for all teachers, right answers to all test questions, students following procedures written by outside authorities, class periods too short to think in, teachers as the only audience for students' work, and abstractions separated from experiential context.

How we shape and engineer the technology, tools, organization of knowledge, and virtual communities on the expanding Internet information infrastructure will directly affect the potential productivity, roles, and equity of opportunity of young people in the near and distant future, and thereby will affect the kind of society into which we evolve.

These examples of learner and teacher contributions to the current Internet provide a glimpse of what is possible with today's technology, infrastructure, and organizational arrangements. However, the value that people can contribute and the value that they get is limited by the local networking infrastructure, tools, and services on the Internet, and by the free-for-all nature of the interactions on most current virtual communities. Most contributions wind up as flotsam and jetsam on a vast chaotic sea of e-mail, newsgroup messages, and Web pages--with little order, discipline, quality assessment, structure, retrievability, review, or aggregation.

There has been considerable recent progress in developing software that makes it easier to get onto the networks and discover information from personal computers. As more people attempt to participate and more virtual communities are formed, we are gaining more insight into the kinds of tools and services needed for full participation, including user construction of knowledge and information services. The Clinton-Gore Administration's National Information Infrastructure plan recognizes the importance of broad-based participation in the development of the Internet and the evolving nature of the NII:

[T]he NII will be of maximum value to users if it is sufficiently "open" and interactive so that users can develop new services and applications or exchange information among themselves, without waiting for services to be offered by the firms that operate the NII. In this way, users will develop new "electronic communities" and share knowledge and experiences that can improve the way that they learn, work, play, and participate in the American democracy (NTIA, 1993).

----------------------------------------------------------------

V. Vision of Large-Scale Participation

Many factors affect the value of contributions made by individuals and groups. In the National School Network Testbed, BBN is collaborating with over 100 organizations that are exploring models for leveraging Internet access for educational innovation (Hunter 1995). This research has made it clear that scaling up is not a simple matter of physically connecting more people and organizations to the Internet. Rather, scaling up has many dimensions--technical, organizational, educational, economic, and social. What is to be maximized? Is it the number of people who have access to the networks? Is it the ease with which these people can learn to take advantage of the resources? Is it the educational opportunities they have had that make them competent managers of information and creators of knowledge? Is it the contributions that they have an opportunity to make? Is it the accessibility of their contributions to others, within and outside of their own local and virtual communities? Is it the social creativity and solutions to problems that result from this synergy? Is it the effectiveness of a new economy based somehow on individuals' (or groups') contributions to knowledge?

If internetworking and the National Information Infrastructure are to support the transformation outlined here, then "scaling up" has to mean all these things, and more. Decisions made by government agencies, corporations, and communities about investment in infrastructure and educational reform will take into account the mechanisms needed to make progress on all of these fronts. The following four-part vision (of a school as a learning organization) may help to guide our decision-making, particularly with regard to elementary and secondary education in the future:

  1. 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; pre-planned courses, textbooks, teacher training programs, technical support staff, and the like may not always be available to meet an individual's particular learning need. 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. Similarly, software and networked information services for educational purposes will be designed with the assumption that people will be taking on these responsibilities. For example, "ease of use" is a commonly requested characteristic of networks, information services, and software, but there is always a trade-off to be made between ease of use and complexity or functionality. In the quest for ease of use of information and tools in the Internet, we must be careful not to exclude people from participating in the more complex and rewarding tasks of constructing knowledge. Students will learn how to deal with phenomena that are new and more complex than they are "ready" for, and will have opportunities to make sense out of situations before they understand all the first principles.

  2. 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. The communications networks will support teaching by people whose primary work is not formally teaching, but who have expertise in industry and other public sectors. Incentives to perform these part-time and out-of- school teaching and mentoring roles will be devised. Communities and school districts making an investment in new curricula or technology should not attempt to overlay such innovations on outmoded methods of operation of schools; rather, they will look broadly for new opportunities to engage people in nontraditional roles.

  3. 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.

    School itself is a more integrated system. School is divided into smaller clusters, where teachers and students and their families get to know one another and form a sense of community. Collaborative groups work on meaningful projects, and just-in-time seminars and workshops provide support for the projects.

  4. Educational reforms will evolve in synchrony with the evolving information infrastructure. As a society, we are working hard on educational reform at the same time that we are evolving a new information infrastructure. There is a danger that the enormous efforts now put into educational "reforms" will turn out to be irrelevant to the circumstances of learning and working in a networked, knowledge-creating society. Current investments in reformed curriculum frameworks, standards, assessments, teacher in-service programs, and the like should take advantage of networking to reduce industrial-age constraints; at the same time, they can contribute vitally to the evolving information infrastructure to the learning benefit of everyone.
