INTRODUCTION

The use of information and communications technologies to extend educational opportunities ("tele-education") is a phenomenon that is growing rapidly on every continent. It was the topic of a worldwide study conducted earlier this year by the Commonwealth of Learning (Dr. Glen Farrell, Principal Investigator). This author investigated the phenomenon in the United States and the Caribbean. Other researchers reported on Canada, Latin America, Asia, the Pacific, Europe, Africa, India, and Australia. Several items of interest emerged from the study which might be relevant to the UNISPACE III roundtable.

FOUR GENERATIONS OF TELE-EDUCATION

In one sense, today's tele-education is a recent phenomenon, coinciding largely with the evolution of the World Wide Web as a commercial communications vehicle. In another sense, however, at least in the United States, this could be said to be the fourth generation of distance education.

The first generation was the introduction of "correspondence" education in the 1800s, especially its use by the land grant universities starting in the late 1800s to deliver agricultural education to farmers in rural areas.

The second generation came with the introduction of "television" to deliver educational opportunities to all people in their homes. This stage began with the commercial television offering of Sunrise Semester and Continental Classroom in the 1950s and expanded with the introduction on public broadcasting of more highly produced telecourses in the 1970s and 1980s, reaching its apex with the quality courses of the Annenberg/CPB Project in the 1980s and early 1990s.

The third generation began to emerge in the late 1980s when colleges and universities began to offer "on-line courses" sporadically, when the Internet was still largely funded by the U.S. government and was a "club" of university faculty and military personnel. This was an era of experimentation and searching for ways to use the "reach" of the Internet while still taking advantage of all that had been learned from the two preceding stages.

As we approach the end of the 20th Century, tele-education in the United States is entering its fourth generation with the introduction of complete "virtual programs" of study. Until institutions of higher education (IHEs, which includes both colleges and universities) achieved a critical mass of on-line courses, it was difficult to know what impact tele-education would have in the United States.A recent study by the Western Cooperative for Educational Communications (WCET), a program of the Western Interstate Commission for Higher Education (WICHE) (www.wiche.edu), documented the extent to which 1,400 of the 3,000 colleges and universities in the U.S. offer distance education courses and programs (tele-education). The study found that 79% of all the institutions offer one or more distance education course (broadly defined to include correspondence courses, telecourses, Web-based courses, site-to-site videoconferencing, and other delivery modes), and one-third offer one or more complete degree programs at a distance. Those data are consistent with the findings of other recent studies. Most of those institutions offering complete distance education programs do so as an extension of their campus-based programs, which continue to dominate their mission. Only a few U.S. IHEs, such as National Technological University, Western Governors University, and the University of Phoenix, can be considered to be "virtual universities" in the sense that other countries have such institutions.Interest in tele-education at the university level is so great that many traditional universities are rushing to create Web-based courses just so that they can say they are offering virtual learning opportunities. The interest has also spawned the development of a new monthly on-line journal, the Virtual University Gazette (www.geteducated.com/ vugaz.htm) that tracks new programs not only at universities but also those offered by the professions and business and industry. The Gazette is published by Vicky Phillips, CEO of Lifelong Learning (Waterbury, VT), a distance learning consulting firm.Phillips has also co-authored, with Cindy Yager, The Best Distance Learning Graduate Schools, a 322-page publication that profiles 195 accredited graduate schools that offer complete degrees at a distance. Published by The Princeton Review and Random House Publishers, (www.randomhouse.com) the 1999 edition has several chapters of advice for the reader, on such topics as what to look for in distance education programs, how to select among delivery technologies, and how to seek financial aid to pay for the degree. The publication includes degree programs that are delivered through the Internet, videocassettes, audiocassettes, broadcast and cable television, and computer technologies. It also includes a chapter on corporate-sponsored graduate degree programs.

THE PERVASIVENESS OF CHANGE

One of the forces that is driving the expansion of tele-education in the United States is change: change in pedagogical thinking, change in the communications infrastructure throughout the country, and change in the capacity and functionality of information and communications technologies. The pace of change is so great that it is almost impossible to get a stable picture that will be valid for any length of time.

In the first place, our understanding of the nature of learning and the relationship between the learner and the educational institution is changing. At the lower levels (elementary and secondary schools), the emphasis is on learning that is student-centered, project-based, and activity-oriented. It is based largely on the pedagogical theory of the constructivists (i.e., that students must learn to construct new learning from disparate sources of information). At the higher education level, the change is reflected in a more "customer-centered" approach that affects not only how students are treated as they interact with the institution, but the very nature of the courses themselves, making them more practical, with content that the students can apply immediately in their jobs.

Second, the information and communications infrastructure in the U.S. has expanded greatly, to the point where most households have a full range of telecommunications technologies. The technologies are becoming an integral part of life in most households. It is not unusual, for example, for middle class households to have several television sets, cable television service, a couple of VCRs, one or more computers, two phone lines, a cell phone, video games, and more. It is important to note that educational applications are not driving the increased accessibility of these technologies. Commercial interests are driving their expansion. Educators are the beneficiaries of this expanded availability of the technologies.

Third, the technologies have experienced great expansion of functionality in recent years. Whereas in the past, cable television systems were limited to 12 channels, and computer storage was limited to 20 megabytes of storage, and telephone transmission of data was at a slow speed of 1200 baud, now the technologies have much greater capacity and functionality. Cable systems regularly carry 130 channels of programming and are expanding to offer telephony and high speed data access as well as television programs. Computer storage of 8 to 10 gigabytes and processing speeds of 400 megahertz are now available at reasonable prices. Data travel through telephone lines at up to 53 kilobytes per second. And we in the United States are blessed to have an affordable fixed-price telephone pricing system so that we can use the Internet for an unlimited amount of time each month for one low monthly charge. This is something that many other countries do not enjoy.

Furthermore, the technological differences among the media that once separated them from each other are quickly disappearing. The emergence of a single communications platform that supports the interoperability of technologies is no longer a pipe dream. We live in the "age of convergence."

The expanded capacity of the technology has also encouraged the development of new applications, most of which were stimulated by non-education interests, but which nevertheless hold promise for educational applications. Real Video, for example, was developed to "stream" live television and radio programming. But what potential it holds for educational applications! Likewise, video conferencing networks (such as the 400+ site Sprint Video Network) were developed to facilitate business meetings. But what potential they hold for remote site-based distance education!

The telecommunications industry itself is stimulating further change. Industry jobs that did not even exist ten years ago now require training and work force upgrading annually, if not more often. This is having a major impact on the work force itself. For example, in a small area of Northern Virginia, there are 19,000 hi-tech jobs that are vacant because there are not workers with sufficient training to fill them.

All of these changes are converging to create a time of unprecedented opportunity for new ways to deliver and support educational opportunities. Tele-education is a major beneficiary of the changes.

MORE THAN APPLICATIONS OF TECHNOLOGY

It is easy to become wrapped up in today's technologies and to lose sight of the pedagogical purposes of tele-education. Indeed, the technologies have a certain allure, and in some cases they have been at the center of educational applications. However, as IHEs get more experience with offering tele-education courses, they soon realize that the new delivery platforms demand a new paradigm of learning. It is no longer feasible to use the "sage on the stage" paradigm that has dominated traditional education for centuries. The learners must play a much more active role and they need wide flexibility in when and how they access the faculty member, other students, and instructional resources. The role of the faculty member has to change. The types and quality of instructional resources that support learning have to move beyond the traditional textbook model.

Many institutions have tried various new approaches, and the search continues. One paradigm that holds great promise is the model of "The Four Conversations." The model places a strong emphasis on the dialogic nature of learning. It maintains that all learning consists of four types of dialog:

a. the "conversations" a learner has with an instructor;

b. the "conversations" among groups of learners;

c. the "conversations" a learner has with instructional resources; and,

d. the "conversations" a learner has with him/herself (i.e., reflection).

The challenge for tele-education is to make appropriate use of communications technologies to support each of the four dialogs. An assessment of tele-education programs would examine: how well the programs facilitate the learner communicating with the instructor (asynchronously or in real time); how the learner can contact other students to discuss issues and study together; how the learner has access to the instructional resources of the course and the tools needed to use those resources; and how the program encourages the student to assemble and reflect on the information gotten through the first three conversations.

TWO BARRIERS TO EFFECTIVE TELE-EDUCATION

Many tele-education programs in the United States have run up against two barriers that are often not apparent but present real hurdles to further development of the programs. The first barrier is that they are technology-driven. The programs themselves are often initiated because a new technology becomes available (e.g., a videoconferencing facility, a new television production studio, etc.). Even those that have pedagogical starting points often become "tracked" into a process that uses one or two technologies which invariably introduce limitations to the program.

The second barrier is that the tele-education programs adopt a traditional pedagogical paradigm. They create a learning environment that closely resembles the roles, processes, and resources found in face-to-face learning programs.

In succumbing to these two barriers, tele-education programs fail to take full advantage of a range of resources available to the instructor and learner alike. Furthermore, they fail to employ the full power of some of the new information and communications technologies to support improved pedagogical approaches.

Those who are inclined to doubt the existence of these two barriers should consider the examples shown in the grid below. It shows clearly that most of today's tele-education programs are technology-driven and based on a traditional academic paradigm. The reader is encouraged to plug other programs into the grid. The author is especially interested in learning about programs that might appropriately fall into the lower right quadrant of the grid.

Notes:

(a) Educational television programming of the 1950s, such as Sunrise Semester

(b) Telecourses of the 1970s-80s

(c) Audio and video conferencing of the 1980s-90s

(d) One-off Internet courses and "shovelware" of the 1990s

(These applications tend to be driven primarily by one technology and to follow the discursive approach of a traditional classroom. They transfer the traditional classroom paradigm to a new medium.)

(e) Interactive CD-ROM courses of the 1990s

(Some of today's CD-ROM course projects, while still technology driven, are reaching to use the technologies in ways that were not possible before the advent of today's technologies.)

(f) Video and audio courses of the Annenberg/CPB Project of the 1980s-90s

(These courses had three unique characteristics: first, they were created to serve a social need – to provide tertiary-level educational opportunities to those who could not take advantage of traditional opportunities; second, they took advantage of advanced educational design to allocate to various media the part of the instructional process they could do best; and, third, they had built-in quality control procedures.)

(g) Approach of the Western Governors University

(The suite of products and services provided by WGU is also designed to serve a social need – to make educational services available to larger numbers of learners at times and places of their choosing, using a variety of appropriate technologies.)

(h) Approach of innovative corporate universities of the 1990s

(Some corporate universities are developing new pedagogical paradigms that often mix new instructional approaches (such as shorter, more intense courses) and new applications of the technologies.)

(j) Approach of the University of Phoenix

(This is a highly consumer-driven model that uses a mixture of traditional and newer instructional approaches and technologies.)

(k) New services such as those offered by the PBS ACCESS Project

(While not a program of study, this project is developing a suite of services that will help learners craft an individualized distance education program by taking appropriate advantage of a variety of instructional packages and support services delivered through a variety of technologies.)

SAMPLE PROGRAMS IN THE UNITED STATES

This section will describe a few selected leading edge initiatives in tele-education in the United States at the close of the 20th Century, especially those that are scaleable worldwide through space technology. It does not pretend to be a comprehensive listing of all such programs in the country. In fact, for every program included, there are dozens that have not been included.

The programs described below share some common characteristics:
