Investigate and Decide Learning Environments: Specializing Task Models for Authoring Tool Design

The complexities of building educational software can be reduced by relying on appropriate tools for adapting and re-using similar, previous applications. Although researchers have been creating tools for automating some aspects of software design, most of these tools typically aim for generality, attempting to cover a broad class of interactive programs in many domains. However, this approach may not be effective for building complex interactive systems, and fails to re-apply the instruction and design expertise implicit within prior software applications. An alternative is to provide tools which use specialized, rather than general, task models, tailored specifically to a target category of software. In addition, an understanding of the authoring task itself can inform the design of such specialized authoring environments. This article presents a prototype authoring tool for interactive educational software, called IDLE-Tool. Investigate and Decide Learning Environments (IDLE) is introduced as the task model around which the tool is based, and a model of the authoring process, called Guided Case Adaptation, is offered as an approach to employing the model and an exemplar in tandem to effectively support the design process.     

Metadata and Memory: Lessons from the Canon of Memoria for the Design of Content Management Systems

To date, most of the research on usability and content management systems has focused on the end-user products of such systems rather than on the usability for technical communicators of the single-source authoring tools offered within these systems. While this latter research is undeniably important, attention needs to be paid to the plight of technical communicators attempting to use single-sourcing tools. Otherwise, technical communicators in workplaces risk becoming semi-skilled contingent labor rather than empowered knowledge workers. This essay, therefore, attempts to open a debate about the design of content management systems by turning to the rhetorical canon of memory as an appropriate source for insights into how stored information can be flexibly retrieved and used during composing activities.

AIDA: a methodology independent support tool for educational software authoring

Many authoring tools have been proposed in an attempt to find more effective ways to face the challenge of developing educational software. However, most of them are reported to be restrictive, since they are strongly connected to a specific educational software development methodology. The AIDA (Ambiente Integrado para o Desenvolvimento de Aplicações educacionais) authoring environment was developed at the University of Coimbra having as its main objectives the support of most of the activities involved in authoring and making educational software development easier. The AIDA system is based on a design module, i.e. a prototyping tool allowing the creation of Windows-based software, including multimedia features. The system assists evaluation activities and it caters also for support on translation and cultural adaptation, as well as on the reutilization of educational materials. The use of the AIDA environment is illustrated by three small examples using different development methodologies.     

AIDA: An integrated authoring environment for educational software

This paper describes an integrated authoring environment, AIDA (Ambiente Integrado de Desenvolvimento de Aplicações educacionais). It is an open tool, giving the author a high degree of freedom both in package characteristics and design methodologies used. This environment integrates several modules. The core of the design module is a prototyping tool, allowing the creation of evolutionary prototypes. These prototypes can include several types of multimedia components and can be used as part of the final package. The AIDA environment also includes other options that support evaluation, learning materials re-use, communication between authoring team members and translation and cultural adaptation of packages to work in different environments. An experimental version of this authoring environment was implemented and the results of its evaluation are encouraging. In this paper we also present an example of a package created with the AIDA authoring environment.     

Creating next generation blended learning environments using mixed reality,Video Games and Simulations

Summary The goal of this article has been to discuss next generation learning environments and next generation training technologies as well as the learning and design challenges faced in using these. Specifically, we discuss theoretical and design principles of constructivist learning environments and how advanced technologies can potentially support meeting these principles as well as the challenges they may pose to various types of designers, instructional, game, graphic and programming. To address methods for designing complex environments, we also address the use of methodologies and authoring systems with various tools to support the design process. In this context, to illustrate how tools can be used to help instructional design teams manage the complexities of developing for these environments. As an example, we discuss one tool,IIPI CREATE, that supports this process and organizes the development process     

Cognitively based models of courseware development

Many researchers are attempting to develop automated instructional design systems to guide subject matter experts through the courseware authoring process, a process that usually includes analysis, design, production, implementation, and maintenance. What is lacking in many existing efforts, however, is a systematic method for analyzing the interplay between user characteristics, the authoring environment, and the resulting quality of computer-based instruction (CBI). In this article, a cognitively oriented method for developing a useful and predictive model of the process of designing CBI is proposed, and its use in three small-scale case studies in Air Force training settings is reported.

Modeling and supporting the authoring process of multimedia simulation based educational software: A knowledge engineering approach

Traditionally, support for authoringeducational software focuses on the authoringprocess: the nature and sequence of theactivities that must be performed to deliverthe required product. As a consequence, themethods that are used tend to have a stronglinear flavor, which resembles the classicalwaterfall approach. Development strategies ascurrently used in software engineering shiftthe attention from activities to products(see De Hoog et al., 1994). A generalimplementation of this approach can be found inthe CommonKADS methodology (see Schreiber etal., 2000). The present article describes howthis new development approach has influencedthe design of an authoring system formulti-media simulation based educationalsoftware, the Simquest authoring system.     

Authoring for simulation-based learning

This paper describes the SAM (Simulation and Multimedia) project and the rationales behind it. SAM focuses mainly on integrated simulation-based learning environments and creates a framework for authoring, modelling and learning. In these frameworks existing software tools are used where possible and an exchange of tools is enabled. Specialised tools support all actors: learners, authors and modellers. Emphasis will be put on methodologies and graphical tools supporting global course design and integration of simulations. Tools enable also the implementation of general and local course control including instructions for the monitor to recognise and evaluate learner behaviour.SAM methods and techniques are developed to design adaptable courses to meet different learner profiles and to integrate simulations in courseware. This implies a technical integration: the simulation package must accept external control and support an exchange of data. It also implies a conceptual integration: instructional domain concepts must be connected with the model entities; variables, parameters and relations.     

Interactive technology and authoring tools: A historical review and analysis

Computer systems, interactive technologies, and the software tools for authoring multimedia programs have evolved over the past several decades. The evolution of multimedia technology is discussed and current alternatives for authoring multimedia programs are described. Issues related to analyzing authoring tool requirements and selecting software are presented and trends in the evolution of authoring tools are identified. Many factors affecting the selection and use of authoring software are exogenous to the technology itself. Both technological trends and market forces must be considered.     

Flexible authoring and delivery of online courses using IMS Learning Design

Since the publication of the IMS Learning Design (IMS LD) specification in 2003, many initiatives have been undertaken to build authoring tools that are simple enough to be used by non-technical instructors and teachers. IMS LD's technical complexity is believed to be a major burden for the adoption of the specification. We have developed a new approach for course authoring and delivery that hides most of the complexities and is powerful enough to create highly flexible online courses. Key aspects in this approach are (1) integration of IMS LD authoring and delivery tools in order to enable teachers to adapt courses in runtime and (2) the use of templates to standardize aspects of the LD. This article reports on the research and development of this approach, as well as a first implementation by the Open University of the Netherlands as part of an integrated e-learning system.     

Information,Instruction, and Learning: A Hypermedia Perspective Originally published in 1991, PIQ 4.3

Hypermedia as defined by Osgood (1987) is a tool for linking nonlinear information presented in the form of graphics, animation, video, and sound. One important question for instructional designers regarding hypermedia is how it can be used as an instructional or learning tool that enhances rather than inhibits learning. Creating hypermedia applications is a quick and easy alternative to creating courseware with older authoring systems and languages which took many hours to learn. This ease of application creation, combined with a tremendous increase in information available to our society, has resulted in a proliferation of hypermedia databases in school, university, and industry settings that is gradually moving into homes. Many of these databases are simply information media. This paper identifies important issues related to classifying a hypermedia-based information system appropriately. Based on a discussion of these issues, a call for systematic research which clarifies the role that hypermedia-based information systems can and should play in an instructional or learning environment is set forth.     

Needs of elementary and middle school teachers developing online courses for a virtual school

Eight teams of elementary and middle school teachers developed pilot online courses for the North Carolina Virtual Public School (NCVPS) in the USA. A qualitative case study with focus groups and a follow‐up survey helped to identify common needs of these non‐traditional course designers during course development efforts. Findings suggest virtual schools can better support non‐traditional course designers by providing leadership components such as technical expertise, regular feedback, and clear expectations, including an understanding of the target students. Findings further suggest designers need a range of bite‐sized professional development on replicating model courses, using course management systems, assessing learners online, designing with copyright and safety issues in mind, integrating Web tools, and developing course documentation for deployment. The article concludes with a discussion of support structures that may aid instructors tasked with online course development.     

Computer-aided authoring of assessment instruments: An activity-theoretical approach

Abstract

Various researches have been conducted on the role and importance of assessment in education as well as its impact on the learner and the overall learning process. In fact, the way assessment is formulated in a particular subject shapes the way students learn. They focus their learning to comply with assessment requirements that they anticipate. In this article, the study is focused on the written examination papers (teacher-made tests) that are normally prepared at the end of a semester or an academic year to assess students of secondary and tertiary levels. The study also investigates how well papers are set and balanced according to the cognitive levels defined by Bloom (1956) and the learning outcomes/objectives as defined for the subjects. A collaborative process model as a framework for the design of such tests that can enhance the evaluation process is proposed. A brief argument is made for a case for a computer-supported collaborative environment to implement such a framework and which is based on activity theory. Such a framework is implemented in the form of MYSTIC; a collaborative authoring software for assessment instruments. The software allows stand-alone as well as collaborative authoring of examination papers and also helps academics' decision-making concerning the examination paper balancing and moderating process by graphically displaying and comparing marks allocated per question paper against the learning objectives     

Techniques for Creating Computer-Based Instructional Text: Programming Languages,Authoring Languages,and Authoring Systems

This article examines the use of computers to deliver instructional text. The focus is on procedures for the creation of computer-based instruction (CBI) lessons. The development of CBI lessons is separated into two aspects: the design of the lesson and the authoring of the lesson. Three primary techniques for authoring CBI lessons are the use of general-purpose computer programming languages, CBI authoring languages, and CBI authoring systems. These authoring techniques are described, including the advantages and limitations of each. Authoring systems are divided into three categories according to the type of CBI lesson they will support. Considerations are given for selecting from among the authoring techniques. Emerging trends in authoring techniques are discussed.     

We!Design: A student-centred participatory methodology for the design of educational applications

The development of educational applications has always been a challenging and complex issue, mainly because of the complications imposed by the cognitive and psychological aspects of student–computer interactions. This article presents a methodology, named We!Design, that tries to encounter the complexity of educational applications development from within the participatory design framework. The methodology enables computer literate students and designers to cooperate in the design of applications that (1) enhance typical educational processes for which students have extensive experience in, such as note taking or assessment, and (2) are well‐suited to the technological, social and cultural particularities of each educational environment. The methodology can be easily applied in real educational contexts and consists of two phases. During the first phase, students participate in short‐duration design sessions where they formulate needs, tasks and interface prototypes for the educational application under examination. In the second phase, the designers systematically analyse and then integrate student suggestions. In order to evaluate the methodology, it was applied in the design of two educational applications: an electronic assessment environment and a course website. A total of 86 undergraduate informatics students participated in 22 4‐hour design sessions. The methodology was evaluated by collecting students' responses through questionnaires and by introspection on the video recordings of the design sessions. The design sessions proved to be a very intriguing experience for the students while the methodology's products managed to respond to their personal needs and expectations in an efficient and effective way.     

The current status of instructional design theories in relation to today's authoring systems*

It is of course very difficult to accurately project important characteristics of the future state of any rapidly evolving field, and the field of authoring systems for computer‐assisted instruction (CAI) is no exception. However, strong trends in evolving CAI systems of today would seem to indicate some important characteristics of the software systems underlying tomorrow's automated instructional systems. Under the premise that form follows function, this paper will explore the functional impetus of some of the most important trends extant in terms of their roots in a powerful, emerging technology of instructional design. This technology promises to complement the advancing hardware and software technologies, by supplying that sine qua non of successful instructional materials. It is inevitable that systems of the future will make (and indeed are making) significant accommodations of this vital technology as it matures, and therefore some important characteristics of tomorrow's systems can be predicated upon what is already known of this technology of instructional design.
