Introduction

As the Internet is rapidly emerging, the World Wide Web, commonly known as the Web, has become an increasingly prolific and dynamic medium for sharing information (Khan, 1997). The recent emergence of the Web as a new learning medium (delivery system) is definitely a blessing for education and training fields. The Web provides an open, dynamic and flexible learning environment with implications for countless applications with respect to education and training. Numerous names are used to describe Web-Based Learning (WBL) activities, including Web-Based Training (WBT), Web-Based Instruction (WBI), Internet-Based Training (IBT), Online Training (OT), Advanced Distributed Learning (ADL), Online Learning (OL), and Distributed Learning (DL) to name a few; for our purposes, however, we will use WBT.

The design, development and implementation of WBT for a distributed, open and flexible environment would greatly benefit from an authoring system, which allows designers to create meaningful educational/training materials. This chapter discusses important aspects of authoring environments for open and distributed system. In creating WBT, we should explore the similarities and differences between open and closed systems. An understanding of open systems and its systemic relationship with various components of the learning environment would play a very critical role in WBT design and development.

Open vs. Closed Authoring Tools

Most of the larger and more established authoring tools that currently exist, such as Asymetrix ToolBook and Authorware, were developed with a closed system in mind. In addition, this older generation of authoring tools were designed to accommodate the assumption that the learning resulting from the CBT would take place in a state of solitary confinement. These tools were instrumental in helping a designer to create Computer-based Instruction (CBI), Computer-assisted Instruction (CAI), or Computer-based Training (CBT), for example, which almost always called for some degree of interaction between the learner and content to meet the instructional goals (Phillips, 1998). WBT challenges us to break the solitary confinement of closed systems (CBT) by designing for an open, flexible and distributed learning environment. To point, Phillips (1998) contends that the Web provides opportunities for learners to experience instruction on three levels:

  • Between the learner and content,
  • Between the learner and instructor and
  • Among other learners.

“One of the challenges for instructional designers charged with the task of suggesting the best use of an instructional medium such as the World Wide Web is the inevitable and incessant rate of change of information technologies” (Welsh, 1997). The Web as a learning medium has tremendous potential for delivering instructional materials, but becomes problematic for designers and developers when using authoring software that may not be able to accommodate new functionality of emerging information technologies.

Web-Based Authoring for Open Systems

The demand within the past five years has sharply increased for WBT (virtual universities, corporate intranets and extranets). According to McGee (1999), "Technology-based training, including Web-based solutions, will represent half of all training by the year 2002, up from 25% [in 1998]." For example, The White House Office of Science and Technology Policy (OSTP) and the Department of Defense (DOD) launched the Advanced Distributed Learning (ADL) initiative to ensure ready public access to high-quality education and training materials on the Web that can be tailored to individual learner needs. This ADL initiative and most of the literature surrounding WBT address several common goals. At present, there is not a single authoring tool that adequately addresses all issues concerning Web-based learning environments.

Because the Web is a new medium and many of us in the field of education and training are used to developing learning materials for closed systems (e.g., CAI, CBT, etc.), developing learning materials for open systems (e.g., WBI, WBT, etc.) can pose a new set of challenges, for which solutions are still in the formative stage. “While having an open system has its appeal, it can make designing for it extremely difficult, because in an open system, the designer agrees to give up a certain amount of control to the user” (Jones & Farquhar, 1997). Instructional designers now face difficult choices regarding tool selection, with particular concern as to whether a given tool will be stable enough in the future not to require adjustments and re-programming to their products in the future. Even more importantly, many designers are wondering how they will be able to implement with success a newer instructional paradigm (indirect instruction) in a medium that is not yet fully comparable (in terms of productivity) with the high interactive functionality of the old paradigm (direct instruction) (Gibbons, Lawless, Anderson & Duffin, 2000).

In designing WBT, we must focus on issues important to learners and how to use the Web’s potential in concert with instructional design principles (Ritchie & Hoffman, cited in Khan, 1997a). Khan has been researching the question, “What does it take to provide the best and most meaningful flexible learning environments for learners worldwide?” He learned that there are numerous factors that help to create a meaningful learning environment (see chapter 8), many of which are systemically interrelated and interdependent. A systemic understanding of these factors can help designers create meaningful distributed learning environments. In addressing these systemically interrelated issues for WBT we should seek support from the following knowledge bases (but not limited to following): Instructional design, cognitive and educational psychology, curriculum development, distance education, innovation and change, telecommunication, database, artificial intelligence, software engineering, and media production.

Status of Web-based Authoring Tools

To date, many of the existing Web-based authoring tools do not seem to address many of the aforementioned critical factors surrounding WBT. Some authoring packages for closed systems are trying to expand their capabilities for the Web by allowing designers to simply “upload” current CBT to the Web, for example. However, as we already learned years ago in translating print-based materials to CBT, it is again important to note that authoring tools not initially developed to accommodate an open and flexible system may not be able to address the scope and needs involved in designing purely Web-based instructional and training materials.

Currently, existing Web-based authoring tools do not support the pedagogical and other critical issues that arise when instructional materials are transported to the Web. At a recent PC Week Magazine PC Week Shoot-Out held at the Institute for Defense Analyses in conjunction with the U.S. Department of Defense, PC Week Labs and Shoot-Out judges from the corporate, higher education, and government sectors evaluated systems designed to manage the distributed learning process. Several judges emphasized concern surrounding pedagogical implications and other issues relating to open and flexible learning systems. Specific reactions include the following observations: "Across all industries and academia there is a tremendous concern for standards and for finding just the right instructional methodologies and metaphors" (Plagis-Tsitsikaos, 1999, p.134). In addition to pedagogical issues, Khan (1999b) noted, “Major challenges in designing distributed courseware are management, user interface, resource support and cultural issues" (p. 134). “Area of specialty is understanding how people learn. Need for morre dynamic, flexible, adaptive systems” (Sonwalker, 1999, pp. 134).

Dabbagh, Bannan-Ritland and Silc (2000) used the WBL Framework to review courses

developed by several of the more popular Web-based authoring tools. They found that the

WBL Framework (see chapter 39) provides a competent guiding mechanism for the

development of the Web-based courses. According to Dabbagh, Bannan-Ritland and Silc

(2000):

In order for WBI to be effective, it must be pedagogically driven, dynamically designed, interaction oriented, and content specific. Focus should be placed on designing a pedagogical approach appropriate for the content, inclusion of organization and interaction strategies that enhance the student’s processing of the information, and integration of the medium’s attributes to support the designated goals and objectives of the course. Developers of Web-based training and educational materials need to place emphasis on these tasks and view the technology in relation to its capacity to deliver the planned design.

There is a tremendous need to develop an authoring “system” which will address all WBT-related issues discussed above. After reflecting on the various factors critical to open and flexible learning environments, Khan (1997b) developed aFramework for Web-based learning(see Figure 1). Various WBT factors are clustered into the following eight dimensions:

  • Pedagogical
  • Technological
  • Interface Design
  • Evaluation
  • Management
  • Resource Support
  • Ethical
  • Institutional

Each dimension has several sub-dimensions (see column 1 Figure 3) consisting of items that address a specific aspect of a Web-based learning environment. To find more detailed information about the WBL framework please read chapter 8. Khan (1998) strongly believes that the WBL framework should provide the architecture for a comprehensive authoring system for an open and flexible learning environment. As previously noted, Dabbagh, Bannan-Ritland and Silc (2000) found that the WBL framework provides a competent guiding mechanism for the development of the Web-based courses. In addition, after reviewing the framework, Reeves (personal communication, 2000) indicated that it provides a useful approach to clarifying the complexities of Web-based learning environment.

Figure 1: The WBL Framework

AuthorWeb

The suitability of the WBL framework is so comprehensive that it was significantly instrumental in developing AuthorWeb, a Web-based authoring system for designing open learning environments (Khan, 1999a). At present, no other tool is available to adequately address the issues concerning all eight dimensions of the Web-based learning environments. In 1997, Khan developed the conceptual model for AuthorWeb and presented it at the 1999 Association for Educational and Communications Technology (AECT) convention. The response toward the development of AuthorWeb was overwhelmingly positive. The inception of AuthorWeb’s development began with a vision of providing a tool that would assist educators, trainers and course developers to create meaningful online courses without prior skills or knowledge in instructional design, computer programming and issues critical to distance learning environments. AuthorWeb’s development process benefits from the input of various substantiated perspectives, including instructional design, cognitive and educational psychology, curriculum development, distance education, innovation and change, telecommunication, database, artificial intelligence, software engineering, and media production.

As we discussed earlier, AuthorWeb’s framework is rooted in the WBL framework (Khan, 2000). Each dimension of the framework has several sub-dimensions (see Figure 2), each consisting of items focused on specific aspects of the WBT learning environment. These items are represented as simple queries in the AuthorWeb system. AuthorWeb can be used in two ways, (1) By providing the designer with the flexibility to create a course using its various features and tools like any other comprehensive authoring software, (2) By providing the designer with five easy-to-follow stages of development for course creation (see Figure 2).

Figure 2: Course Creation Process by AuthorWeb

As previously stated, creating effective WBT can be an overwhelming process, and the WBL framework with its eight dimensions addresses the comprehensive nature of the WBT learning environment. The five-stage course creation process outlined by AuthorWeb adequately involves the designer in creating comprehensive WBT. At each stage, the WBL framework helps the designer to identify and clarify the critical issues and complexities in the WBT environment, and provides guidance on addressing these issues appropriately. The following section outlines the course creation process.

Stage I. Initiation

In its opening screen, AuthorWeb provides the designer the opportunity to express the vision of the overall instruction. This vision will eventually be translated into a course. At this level, the designer can include any information they feel is necessary to convey into their vision of the course. AuthorWeb will provide guidance in this process through a series of basic questions aimed at refining the designer’s vision to a more concrete and discrete level. These questions may include, for example: “What would you like your students/trainees to be able to do at course completion?” For conceptual support, the designer will have access to examples of other vision narratives in the AuthorWeb database as well. The goal for this vision creation step is to encourage the designer to articulate what they actually want developed without the perceived limitation of an instructional model traditionally imposed by a given software package. AuthorWeb includes functionality to allow the user the revisit and/or rewrite their initial vision and save it in a searchable database – or a designer can opt to skip this vision creation step all together.

Stage II. Design

Once the vision is created, AuthorWeb will retain and abide by the scope of the designer’s original vision throughout the development process. The steps that follow will introduce the WBL framework into the vision to create a truly meaningful Web-based learning environment. In effect, the designers will be asked to consider and address all eight dimensions and sub-dimensions of the framework (see Figure 3). The designer starts at the pedagogy dimension, but they will then be able to determine the sequence in which they will address the seven remaining dimensions. Not that the designer can also leave and visit another dimension at any time in their development process.

AuthorWeb provides an easy-to-use Design Table format that guides the designer through the process. Figure 3 is a snapshot of the Design Table which includes scrollable columns:

  • Dimension Column lists all eight dimensions and sub-dimensions of the WBL framework, which encompasses the WBT learning environment.
  • Item Column contains items related to all dimensions.
  • Feature Column contains the AuthorWeb features.

The functionality of the Design Table is very flexible. The designer can start with any of the three columns of the Design Table. If a designer chooses to start with the dimension column by selecting a specific dimension, which will prompt relative items and features to appear in the item and feature columns respectively. For example, the selection of the 5.2 sub-dimension prompts items 5.200 through 5.299 to appear chronologically in the item column and the relevant feature will appear in the feature column that is most related to item 5.200.

The naming convention of AuthorWeb's features was selected in a way which will allow designers to immediately recognize its basic functionality. In addition, each feature will be supplemented with a description. If the designer encounters content-specific items that are not in the list (i.e., item column), the designer can simply locate the AuthorWeb feature that most closely addresses that content-specific issue. In addition, by using AuthorWeb, a designer may be able to identify more items relevant to their course content. As new technology and research surrounding WBT emerges, AuthorWeb will make sure more and more of these items and their relative features are available to the designers and learners. Because all issues surrounding WBT can be placed in AuthorWeb’s WBL framework, the inclusion of such new items will be facilitated by the AuthorWeb’s adaptive software.

Figure 3: An AuthorWeb Feature for an item relevant to a WBL Dimension.

Within the scope of this chapter we will only be able to highlight and briefly discuss a few of AuthorWeb’s features. The following section lists some of AuthorWeb’s features:

Breaking News

If a designer would like to use multiple methods for announcing changes in the course schedule, course assignments, etc., AuthorWeb can afford the designer a high degree of latitude with the Breaking News feature (originating from the management dimension of the framework). This feature provides the learner with multiple options for receiving key communication pertaining to course announcements (see Figure 3).

Instructional Design

AuthorWeb’s Instructional Design feature (originating from the pedagogical dimension) will provide designers with just-in-time guidance on instructional theories, models, methods and strategies for both well-defined and ill-defined domains of learning as it relates to course content. Whatever the pedagogical philosophy (instructivist or constructivist) espoused by the designer, this feature will give the flexibility to choose the best method, given their course vision and course attributes.
