Instructional design (ID) is the systematic process of planning events to
facilitate learning. The ID process encompasses a set of interdependent
phases including analysis of learners, contexts and goals; design of
objectives, strategies and assessment tools; production of instructional
materials; and evaluation of learner performance and overall instructional
design effort (Gagne, Briggs, and Wager, 1992).
Automated instructional design (AID) tools assist instructional designers and others in creating instructional products to improve learning. AID systems aid in the production of courseware (Gros & Spector, 1994), or in the development of computer-based instruction (CBI), although some tools guide users in general decision-making that can apply to a range of instructional products and solutions.
AID tools may eliminate some physical ID tasks such as storyboarding and test generation (Muraida & Spector, 1993). However, the strength of AID tools lies in their ability to guide novices and non-ID professionals through the process of creating effective instruction (Tennyson & Barron, 1995; Chapman, 1995). AID tools are especially useful in situations where instructional design expertise is lacking and subject-matter experts and others are responsible for developing instruction [as seen in military courseware development (Muraida & Spector 1993)].
This Digest focuses on four types of tools that guide users through the ID process: expert systems, advisory systems, information management systems, and electronic performance support systems. Authoring tools are also mentioned as popular mechanisms for supporting the production of computer-based instruction. Some tools contain features representing more than one type of system.
ID Expert from the ID2 Research Group (Cline & Merrill, 1995) was created to develop and deliver computer-based instruction more efficiently. ID Expert is based on Instructional Transaction Theory, a "second generation" theory of instructional design (Cline & Merrill, 1995; Merrill et al, 1996; Locatis & Park, 1992). According to Instructional Transaction Theory, instruction is based on transactions (sets of interactions) between the system and the learner in order to accomplish a given task. ID Expert assists designers in creating transactions by presenting a set of decision-making steps involving instructional components, formatting, resources, etc. ID Expert is considered a prototype system and has not yet been released commercially (Merrill, 1997).
The United States Air Force Armstrong Laboratory proposed two AID approaches that use expert system technology to provide expertise to novice instructional designers and subject matter experts in the design, production, and implementation of courseware used in Air Force training (Spector & Song, 1995). Guided Approach to Instructional Design Advising (GAIDA) uses tutorials and context-specific advice and examples. Experimental Advanced Instructional Design Advisor (XAIDA) uses the Instructional Transaction Theory framework to encapsulate context-specific knowledge. Both of these environments are results of the Advanced Instructional Design Advisor (AIDA) research project (Muraida & Spector, 1993; Spector et al, 1991).
Reactions to Expert Systems: While expert systems for instructional design can teach theory validation and function as authoring tools, they are limited by their inability to support analysis and design tasks (Paquette et al, 1994). ID expert systems attempt to control the instructional design process, a process involving a large number of interrelated elements, and so must rely heavily on the knowledge and experience of the individual practitioner (Duchastel, 1990). Several instructional technologists have proposed systems that more subtly advise the instructional designer, rather than prescribe a set of solutions. Some examples are described below.
Building on Duschastel's "workbench," Paquette et al (1994) introduced a performance support system called AGD (a French acronym meaning Didactic Engineering Workbench). AGD provides procedural instructional design information to guide users in defining the learning system (e.g., analyzing training needs, designing pedagogical structures). AGD includes a rules-based advisory component that offers advice regarding specific design decisions made by users (e.g., amount and nature of objectives).
Other performance support systems tools include Designer's Edge from Allen Communication (Chapman, 1995) and Instructional DesignWare from Langevin Learning Services (Langevin Learning Services). Like AGD, these tools support the planning phases of instructional design, but contain a much more general advisory component (e.g., context-specific online help, wizards, and tutorials).
In contrast to AGD, Designer's Edge and Instructional DesignWare lead designers through all tasks involved in instructional design, but place more emphasis on the ultimate production phase. Both tools provide a graphical representation of the instructional systems design model, thus leading to additional support for completing each step of the model. Data entered by users are cross-referenced with all steps to enhance continuity between phases. Usable reports and documents such as evaluation instruments, content outlines, lesson plans, and checklists can be generated by the users.
The primary difference between the two products lies in their intended audiences and purposes. Designer's Edge is for both novice and experienced instructional designers planning computer-based instruction. The product includes support for scripts, storyboards and other CBI production needs. Integration with external software applications is also supported (Allen Communication, 1997). Instructional DesignWare is intended for course designers and trainers interested in producing either computer-based or classroom training. For this reason, more support is provided for decisions regarding media selection and course and presentation materials (Langevin Learning Services).
Although they do not necessarily support the preliminary planning stages of instructional design, instructional designers use authoring tools in the development phase to produce computer-based instruction (Paquette et al, 1994; Locatis & Park, 1992; Merrill, 1997). Some authoring tools take advantage of the World Wide Web by providing features that integrate Web content into computer-based instruction and deliver instruction over the Web (e.g., WebCT).
According to Merrill (1997), authoring tools simplify the programming process and allow experienced users to create effective and visually-appealing instruction, but require a steep learning curve in order to take full advantage of their features. Current popular authoring tools include Macromedia Authorware 4.0, Aim Tech IconAuthor, WBT Systems TopClass, and Asymetrix Toolbook.
Some AID tools support instructional design by focusing on the cognitive aspects of instructional design (e.g., ID Expert, AGD, etc.). Some highlight the procedural steps of ID (e.g., Designer's Edge, Instructional DesignWare). Others support the production phase only (i.e., authoring tools for computer-based instruction).
In general, AID tools that support the planning and evaluation phases of ID are not as widely used by practitioners as tools that focus on the authoring and media production phases (Chapman, 1995). One exception may be Designer's Edge which has been cited as one of the most popular CBT authoring tools despite its intended purpose as a pre-authoring system (Kemske, 1997). Regardless of its strength or approach, the value of a particular tool or type of system is measured by how well it can support a particular designer's task (Gros & Spector, 1994).
