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.     

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.     

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.     

The educational potential of multimedia authoring as a part of the earth science curriculum—a case study

The purpose of this study was to assess the potential of multimedia authoring, as a learning tool, using the software ASTOUND. The subjects in this study were 32 students in two Grade 12 classes. The context of the study was a multi‐disciplinary environmental unit about earthquakes. Students were provided with basic background about earthquakes via laboratory experiments and field trips. At a later stage, the students did in‐depth independent projects on selected topics related to earthquakes. Once completed, the students presented their projects using the multimedia software ASTOUND . The research consisted of the following stages: a pre‐development phase; curriculum design phase; implementation and evaluation. The research tools included: questionnaires, interviews, observations, concept mapping, and an analysis of the multimedia presentations. The findings showed that an integration of laboratory exercises, field trips, and an independent study project, could lead to meaningful learning. However, although most of the students enjoyed using the multimedia program, there was no evidence to support the assumption that it contributed to knowledge acquisition. In fact, much of the time invested in multimedia authoring was devoted to producing decorative effects, reducing the time available for meaningful learning. © 2000 John Wiley & Sons, Inc.

课件制作软件比较初探

随着现代教育技术越来越多地被应用到教学中来,制作多媒体课件也越来越重要,而选择合适的软件是课件制作的首要问题.文章就几款常用的课件制作软件在数据数据整合、教据处理、动画制作、交互设计能力及易用性、可修改性、播放的系统要求等方面做了一些比较研究,并据此提出各软件适用的情况.     

Authoring systems reassessed

A study of authoring system technology was done to update a previous study done in 1985. While the earlier study focused on software selection methods, the current one emphasizes trends in authoring tool characteristics, vendor approaches to the market-place, and evaluation methods. It also raises questions about some of the often tacit assumptions underlying the technology's development and use.     

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 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.     

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.     

高职院校多媒体教学的探索与思考

目前多媒体教学已经无可争议地成为高职教学的主流,随着教育技术的逐步发展,要求教师将更多更新的教育技术手段包括多媒体制作手段应用于教学[1],为此山东省教育部门也花费了大气力在整个高等院校广泛地开展了教育技术培训活动,但是由于学习时间短、部分教师基础差、培训理论性强具体动手机会少、教师后期的学习得不到保证等问题,所以收效甚微,大部分院校仍然存在教师盲目使用网上下载课件、课件就是教材原文,讲课过程就是念教材、缺乏跟学生互动等问题,尤其缺乏注重动手能力,注重创造思维的优秀教学课件,本文试图从多媒体课件在教学中的运用理念上作深入探讨,实现现代化信息技术在教学实践中的高效运用.     

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.

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.     

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.     

ESCOT: Coordinating the Influence of R&D and Classroom Practice to Produce Educational Software From Reusable Components

In a 3-year project, a consortium of university, nonprofit and commercial educational software developers formed a testbed for the rapid assembly of educational software from reusable component tools. This testbed incorporated interactive learning tools from a variety of university, nonprofit, and commercial developers, and hosted decentralized authoring teams consisting of teachers, developers and educational technologists. Within its testbed, the Educational Software Components of Tomorrow (ESCOT) project achieved notable success in (a) producing a large collection of technology-rich learning activities with reuse rates estimated at 90% and (b) scaffolding authoring teams in successful and rewarding collaborative development experiences. Fortunately, since ESCOT was funded as a National Science Foundation research project, we have had time to reflect on the conditions that led to our achievements. In this article, we reflect on the three activities of the project that we believe were most responsible for its success: (1) the selection of a unit of software production (2) the development of a strategy to allow reuse of interoperable software components and (3) the structuring of a distributed, team-based authoring process. We observe that a common characteristic across these activities was reciprocal influence from both the fields of research-based software development and teaching practice.     

The Potential of Interactive Video

Interactive video combines two well‐established media, video cassette and computer‐assisted learning (CAL), in an attempt to combine the advantages and overcome the deficiencies of both. The paper describes a feasibility study of the medium, using a package that includes a video presentation intercut with interactive CAL programs, on the subject of signals in communication technology. The necessary hardware is described, and two ways of authoring the educational software are compared. Finally, the educational implications of the new medium are discussed together with a consideration of the logistic and administrative problems it presents.     

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.     

Distance Education Trends: Integrating new technologies to foster student interaction and collaboration

Current trends in the field of distance education indicate a shift in pedagogical perspectives and theoretical frameworks, with student interaction at the heart of learner‐centered constructivist environments. The purpose of this article is to explore the benefits of using emerging technology tools such as wikis, blogs, and podcasts to foster student interaction in online learning. It also reviews social software applications such as Writeboard?, InstaColl?, and Imeem?. Although emerging technologies offer a vast range of opportunities for promoting collaboration in both synchronous and asynchronous learning environments, distance education programs around the globe face challenges that may limit or deter implementation of these technologies. This article probes the influence of technology on theory and the possible implications this influence affords.
