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.     

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.

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.

Developing a pedagogical-technical framework to improve creative writing

There are many evidences of motivational and educational benefits from the use of learning software. However, there is a lack of study with regards to the teaching of creative writing. This paper aims to bridge the following gaps: first, the need for a proper framework for scaffolding creative writing through learning software; second, the lack of technical scaffolding in creative writing learning software; third, the need for customizable learning software that requires little programming knowledge; and fourth, personalized learning. To develop our initial framework, Merrill??s First Principles of Instruction is used as pedagogical scaffold and story setting, characters and story structure as component-based technical scaffolds. These were tested in a low-fidelity prototype. User testing indicates an increase in creativity, improvement in story development, clarity of ideas and language skills. We also derive two design principles, i.e. identity and interactivity. Based on these findings, a high-fidelity prototype, named Storyworld, is developed. T-test analyses on results indicate significant improvement in overall creative writing skills, as well as grammar, structure and creativity. The prototype utilizes component-based design in the technical scaffolds, which is encapsulated in a tidy framework that can be personalized for individual learning needs. Our most important contribution is a proper framework combining technical scaffolds and pedagogical scaffolds that not only makes learning more effective and motivating for students, but is also cost-effective in redesigning and personalizing lessons and systems.

Evaluation of a Computer-Supported Learning System

Educational content on the Internet is rapidly increasing. Academics and businesses are placing more course material online to supplement classroom and business training situations. In addition, significant increases in undergraduate enrollments in information system courses, and the rapid pace of new knowledge in the field, have led researchers to call for new innovative approaches to learning. Prior researchers have reported that this new Web‐based training technology (which has its foundation in computer‐based training) has not integrated sound pedagogical practices into the authoring process when developing new tutorials. This paper summarizes an experiment to evaluate the effect on posttest scores of a Web‐based authoring tool that prompts the developer to build multiple presentation styles into the learning module. Early results indicate that the tool is more effective than traditional HTML‐authoring tools and that the number of exercises affects posttest scores in a positive manner. No effect on posttest scores was observed for the number of examples in the learning module.     

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.     

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.     

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.

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.

Educational affordances and learning design in music software development

Although music software has become increasingly affordable and widely adopted in today’s classrooms, concerns have been raised about a lack of consideration for users’ needs during the software development process. This paper examines intra- and inter-sectoral communication pertaining to software development and music education to shed light on the improvement of the educational affordances for music software in classroom teaching and learning. Semi-structured interviews with music software developers (n = 3) and music teachers (n = 15) are used to gain insights into how to enhance the educational affordances of music software. The findings of this study fill a gap in the literature by detailing the knowledge exchange required to effectively develop music education software. Improving the synergy between the knowledge bases of software development and music education could enhance novel educational affordances, providing music teachers with the opportunity to develop new, pedagogically sound music teaching and learning activities.     

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

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.     

Generative aspects of the Computer Based Educational Software System (CBESS)

A system of computer-based instruction (CBI) authoring and delivery tools was developed in which generative CBI techniques were used to dynamically create instructional presentations from content databases during program execution. Three applications using these techniques are examined with regard to trade-offs between case of development and limitations imposed by program specificity: 1) A semantic network was used to represent large bodies of terse facts to be memorized. The need for authors to create large numbers of question screens was avoided by a feature enabling questions and foils to be generated on-the-fly from database assertions as the student programs ran. 2) Technical vocabulary training was accomplished with a generative approach in which an array of student learning activities were automatically generated from a database minimally consisting of technical terms and their definitions. 3) A more difficult program allowed greater interface and lesson control flexibility for creating more sophisticated practice lessons in which new instances were dynamically inserted into templates for questions, anticipated answers and feedback. A common application theme emerging from field-testing the programs was their use in learning resource centers to address specific learning objectives from larger courses.     

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.     

Developing Country-Tailored Policy for the Provision of Schools with Educational Software and Content: The Case of Lithuania

In many countries, the development and introduction of educational software into general education is one of the key issues of national ICT policies. However, differently from other issues of ICT in education, this question is much more country-specific. Therefore, each state shall look for individual solutions that match its economic, social, cultural and other national requirements the best. This paper analyses the development of country-tailored policy for schools' provision with educational software and content. While having generic objectives, the research investigates the case of Lithuania. Initially, the paper gives a review of the Lithuanian context. Then, it analyses the policies and practices of other countries and abstracts potential solutions of the key strategic issues, relevant to the development and implementation of educational software into general education. In parallel with theoretical investigation, the research ratiocinates and demonstrates how each solution, proposed in the Lithuanian strategy of schools' provision with educational aids, has been adapted to the national peculiarities.
