Developing a database of authoring system software

AuthorBase, a working prototype database of authoring system software, was developed as part of a study of authoring software conducted by the National Library of Medicine. In this article, the authors discuss development issues ranging from the scope of the database to what information to document. The prototype demonstrates that records of reasonable integrity can be derived from vendor-supplied information. However, users should understand that the database is only a starting point in searching for authoring software and a resource for becoming generally familiar with the technology.

Authoring Tools for Component-Based Learning Environments

We argue that a focus on building an authoring tool for a complete learning environment is misplaced. An analysis of the task of authoring a commercial educational system reveals it to be best accomplished through authoring separate components. For many of these components, authoring tools already exist and need not be duplicated for use in educational systems. Connecting the various components together is a separate authoring task, and parts of this task are different for educational systems than for typical component-based software. The second half of this article describes the Visual Translator, an authoring tool we have written specifically for this purpose.     

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.     

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.     

The Educational Object Economy: Alternatives in Authoring and Aggregation of Educational Software

The Educational Object Economy (EOE) emerged from research on end-user authoring tools for multimedia software and, by 1997, developed into a library of over 2000 freely available interactive simulations for learning. The organization's original goals and its ongoing interest in alternative methods of software authoring led to continuing connections with component-based software development and collaborative development models. Subsequent focus on learning resource development in developing countries has led to contributions to projects in India, Turkey, Brazil, and other countries. Although the need for learning resources in these and other countries is great, component-based approaches have not yet been adopted.     

Novice and experienced instructional software developers: effects on materials created with instructional software templates

The development of instructional software is a complex process, posing high demands to the technical and didactical expertise of developers. Domain specialists rather than professional developers are often responsible for it, but authoring tools with pre-structured templates claim to compensate for this limited experience. This study compares instructional software products made by developers with low production experience (n = 6) and high production experience (n = 8), working with a template-based authoring tool. It is hypothesized that those with high production experience will be more productive and create software with a higher didactical quality than those with low production experience, whereas no differences with regard to technical and authoring quality are expected. The results show that the didactical quality was unsatisfactory and did not differ between groups. Nevertheless the templates compensated for differences in experience because the technical and authoring quality was equal for both groups, indicating that templates enable domain specialists to participate successfully in the production process.     

Web 2.0 authorship: Issues of referencing and citation for academic integrity

Web 2.0 authoring forms such as wikis and blogs, social bookmarking, and audio and video podcasting pose a challenge to academic authorship traditions. This paper reviews the provisions made in major academic referencing and citation style guides for acknowledging content and ideas that may be published using these new web authoring forms. It offers an overview of features of web 2.0 authoring forms and explores concepts of authoring that can help academics to understand the challenges of working with these forms. It provides examples of referencing and citation in scholarly and scientific communication, and concludes that the conceptual basis of referencing and citation as expressed in current systems and standards needs reform in order to bring academic integrity to the use of these new forms of authorship.     

Evaluating the use of multimedia authoring with dyslexic learners: a case study

This paper reports on the findings of a case study set up to explore the possible benefits that dyslexic learners might have when engaging in the creation of their own multimedia project. Two children with specific learning difficulties worked with the author to develop a multimedia presentation. The children developed authoring skills (such as planning and drafting, composition, revision and reflection, proof reading and presentation) and became active, motivated learners. It is believed that the open-ended character of a multimedia authoring package can encourage creative thinking and interest for content and style of presentation.     

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.     

An authoring and learning kit for digital electronics

A multimedia component kit for digital electronics authoring and learning is presented. It is based on a sophisticated structuring mechanism and a flexible link management scheme. Components available on the Internet facilitate sharing and reuse of educational software during the authoring process, make possible the support of all phases of the learning process, and allow students to achieve their desired depth of understanding. Emphasis is put on the implementation of a great number of components based on simulation and animation that provide a high level of interactivity and allow some presentation difficulties inherent in the subject to be overcome. An analysis of the impact of using the kit for authoring and learning is currently being performed.

Some uneasy inquiries into ID expert systems

Alternative approaches to developing software automating instructional development are described in this article. Information management and expert system approaches are compared. General assumptions underlying the development of all authoring tools, including conventional authoring systems, and additional assumptions underlying the development of expert ID tools are identified. Questions are raised concerning the viability of ID automation tools. It is argued that conventional authoring systems may not be as inadequate or inferior as ID expert system developers have claimed, and that of two approaches to ID automation, tools emphasizing information management are probably most useful. Information management tools, however, still may be inappropriate in some contexts.     

Authoring and GTE

This paper examines GTE from an authoring perspective. It describes how GTE may be used to create a piece of courseware and reviews the potential difficulties that authors face when using such a tool. It summarises two studies that were carried out to investigate how GTE is used by actual authors, and concludes that GTE designs are hard for authors to test and evaluate because of the complexity of such designs. It finishes by arguing that authoring tool developers should give greater consideration to supporting the task of authoring, and that such consideration should occur at all stages of a new tool's development.     

Dynamic Courseware Generation on the WWW

We have developed a tool for the authoring of adaptive CAL courses, called "Dynamic Courseware Generator" (DCG). It generates an individual course according to the learner's goals and previous knowledge, and dynamically adapts the course according to the learner's success in acquiring knowledge. The DCG runs on a WWW server. The learner receives from this server an individualised course targeted to a specified goal. Afterwards, s/he is adaptively guided by the course through a space of teaching materials on the WWW. Unlike other CAL courses on the WWW, a course produced by the DCG is interactive, it tests the learner's knowledge and dynamically adapts to the student's progress. The authoring tool can be used also for collaborative authoring and learning.     

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.     

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.
