Strategies for implementing distance learning coursework have evolved and expanded with the growth and maturation of the World Wide Web. The requirements, advantages, and disadvantages of the most common strategies are compared and contrasted. Initially limited to individual efforts, software development has eased the burden of individual faculty and has opened up strategies for greater participation. Institutions attempting large-scale implementations however may find infrastructure requirements overwhelming. An emerging large-scale strategy involves an institutional partnership with a for-profit Application Service Provider (ASP). The ASP specializes in total systems solutions for developing and delivering Web-based distance learning programs. Recent experiences at California State University, Fullerton with an ASP are discussed.
Introduction
The United States Distance Learning Association’s Website currently defines distance learning as, “the acquisition of knowledge and skills through mediated information and instruction” (2000). While not new, the growth of distance learning offerings has grown significantly over the past five years. Lewis et. al. (1997) in a National Center of Education Statistics [NCES] report, stated that an estimated 25,730 distance education courses were offered by higher education institutions in academic year 1994-95. The primary delivery modes were two-way interactive video and one way pre-recorded video. Lewis et. al. (1999), using the latest NCES survey revealed that by academic year 1997- 98 this number jumped to 54,470. As an indication of the rapid change in delivery modes, term “internet-based technologies” was absent from the 1997 NCES survey and prominent in the 1999 NCES survey. The 1999 survey revealed that asynchronous and synchronous computer based instruction were primary modes of instruction for some courses at 58 and 19 percent of institutions respectively. A major finding of the 1998-99 information technology survey of the National Association of State Universities and Land-Grant Colleges [NASULGC] (1999) was that two-thirds of NASULGC institutions reported collaborating with business/industry, government/communities, other higher education institutions, or other organizations on a “virtual university” or an IT-supported distance-learning project.
The rapid expansion of distance learning has placed pressure on faculty to deliver effective courses, although the efficacy of distance learning has not been proven conclusively. For instance, THE INSTITUTE for Higher Education Policy (1999) reports that there is a relative paucity of true, original research dedicated to explaining or predicting phenomena related to distance learning. In addition, they report that the overall quality of the original research is questionable and thereby renders many of the findings inconclusive. Faculty are still expected to jump on the distance learning bandwagon. A National Education Association [NEA] (2000) poll of more than 400 distance learning instructors indicated that more than half of distance learning faculty spend more hours on their distance learning course than traditional classes. In spite of this, 84% do not get a corresponding reduction in workload, and 63% are compensated for their distance learning course as if it were part of their normal course load. Berg (2000) supports this observation by concluding that there is a tendency towards treating distance learning courses as regular load for faculty and in not including a royalty structure in these agreements.
The need for faculty buy in to distance learning is crucial. The NEA poll (2000) found that three-quarters of the respondents hold positive feelings about distance learning, compared to only 14% who hold negative feelings. Still, it is necessary to assist the faculty in course development and delivery. The Campus Computing Project (1999) survey concluded that assisting faculty efforts “to integrate technology into instruction” remains the single most important information technology (IT) challenge confronting American colleges and universities over the next two to three years. This need is supported by “how-to” guides such as Boettcher & Conrad’s (1999) Faculty guide for moving teaching and learning to the web and Yoakam, Franklin, & Warren’s (1999) Distance learning: A guide to system planning and implementation. Boettcher & Conrad provide faculty and administrators with a set of practical guidelines for implementing Web-based learning in postsecondary institutions. Yoakam et. al. present a comprehensive look at three critical components of a distance learning system: technology systems, instructional systems, and management systems.
A key observation regarding these guides is the increased importance of institutional commitment. The financial investment in Information Technology, according to the NASULGC (1999), currently equals about 5% of a member university’s operating budget (with a maximum of about 11%). Distance learning has evolved beyond simple delivery systems and into the business mainstream. Hanna (1998) identifies and classifies new organizational models that have emerged in the era of digital competition. These involve traditional universities, extended traditional universities and distance education/technology-based universities. Of particular interest is the emergence of university/industry strategic alliances. Syllabus Magazine (2000) in their Buyer’s guide list 13 Online Course Delivery and Development Tools that offer enterprise, or near enterprise solutions. Also listed are six Web Development Tools to assist in the creation of interactive Web sites.
These major implementation tools are only a few years old. They coincide with the growth of the Internet and the World Wide Web. This paper looks at how the web-based strategies for distance education have evolved from pioneering efforts less than ten years ago to the current direction of large-scale implementations involving university/industry alliances. Insights are provided by examining the experiences at California State University, Fullerton. These observations are likely indicative of trend and direction of web-based distance learning.
Multiple strategies exist for implementing distance learning coursework. Factors impacting these strategies include course development, course delivery, computer network connectivity, and the degree and quality of student and instructor support. Course delivery includes issues of remote student interaction with faculty via video, audio, computer, etc. Network connectivity deals with network configurations, transmission speeds, and other technical details. In this context support is related to both time concerns (e.g. is there someone there who can help me?) and technical issues (e.g. why can’t I log in?). Table 1 classifies the “Level” of effort invested in implementing a distance learning course. Each Level requires the involvement of different Participant resources; each would employ different course development Processes; and each requires different degrees of technical infrastructure and support (Connectivity and Student Support). Qualitative terms of Low, Medium, and High are used for each of these factors to provide a point of reference for total labor hours invested, level of technical complexity and organizational commitment.
The Ad Hoc Development process typically entails the use of basic tools such as HTML editors (hyper-text markup language for web pages), or more advanced software packages such as FrontPage, a Microsoft Web site creation and management tool. These tools became available when the Internet went graphical with the advent of browser technology circa 1995. Web page construction software has continued to improve in capabilities and user friendliness; archaic commands and editing are no longer needed. The category, Purchase/license/utilize course development systems includes the use of Web-based learning tools such as WebCT (http://www.Webct.com/) or Blackboard (http://www.blackboard.com/ ). These systems, developed around 1997 by faculty at the University of British Columbia and Cornell University respectively, enable non-technical instructors to produce online courses without much concern for the technical underpinnings of the systems. As well, they provide a self-contained and well-defined Web-based learning environment that developers using Ad Hoc processes would otherwise have to invent themselves. Both these tools were available to develop and deliver Web-based distance learning courses long before for-profit companies adopted them for distribution to a much broader higher education marketplace. In Fall 2000 Blackboard released an enterprise edition that serves as an Application Service Provider (ASP).
The Complete Out source Development/ASP process evolves when institutions partner with for-profit companies (ASPs) for assistance in identifying the market, training theirinstructors, developing their courses, hosting their programs, evaluating their progress, and reporting on the status of the systems. An example of such a vendor is The Learning House, Inc. . (http://www.learnignhouse.com). These companies are only a few years old (circa 1998), and fulfill an important and growing segment of the distance learning market.
The simplest level of Connectivity has an instructor using his or her own desktop PC as a server. Bulletin boards and e-mail capability have existed on mainframes for decades. Using a PC as a server requires some degree of digital communication capability. Limited capabilities were available in the mid-1980s. The simplest level of Student Support results when an instructor is involved in all aspects of communication with students by being available at designated times for interactions, and perhaps communicating via email. “Network” connectivity might involve a school server maintained by instructional staff during normal business hours. Wide spread use local area networks emerged in the late 1980s. Student Support would be available during business hours (typically 9 AM to 5 PM). The most sophisticated Connectivity involves a complete Web-hosted service that is maintained and administered on an around-the-clock basis by either an institution or an ASP vendor. Student Support would then be available for 24 hours/day, and seven days/week (24/7). Mainframe support has historically been 24/7 whereas 24/7 on-line Internet support is relatively recent.
Selecting one level of effort option from each factor may identify basic implementation strategies. Of course, not every combination results in a feasible strategy. One infeasible option would be an Individual Instructor using Ad Hoc Development with a network providing 24/7 support. Another infeasible option would be full institutional participation using a personal computer as a server. Some of the factors fit together naturally. For example, full Web hosting would normally be accompanied by 24/7 support; using a PC as a server would normally have limited support. By excluding the unnatural combinations Table 2 provides five feasible implementation strategies.
