This paper provides a history of the "Pachyderm 2.0 Project," a partnership led by the New Media Consortium (NMC) and the San Francisco Museum of Modern Art (SFMONA), and funded by the Institute for Museum and Library Services (IMLS). The project brings software development teams and digital library experts from six NMC universities together with…

The purpose of this article is to introduce end-user development (EUD) processes to the CALL software development community. EUD refers to the active participation of end-users, as non-professional developers, in the software development life cycle. Unlike formal software engineering approaches, the focus in EUD on means/ends development is…

We will argue that CALL can usefully be viewed as a subset of computer software engineering and can profit from adopting some of the recent progress in software development theory. The unified modelling language has become the industry standard modelling technique and the accompanying unified process is rapidly gaining acceptance. The manner in…

These FORTRAN programs and MATHEMATICA routines were developed in the course of a research project titled "Achievement and Assessment in School Science: Modeling and Mapping Ability and Performance." Their use is described in other publications from that project, including "Latent Traits or Latent States? The Role of Discrete Models…

This book in intended for use by individuals who are comfortable with exploring new software and who want to learn LinkWay (one of a new generation of hypermedia programs) scripting. The book contains several chapters which are divided into three themes. The first part of the book is a review and starts with Chapter 0 providing a brief overview of…

Implementation of a computer-based model for morphological analysis and synthesis of language, entitled P-KIMMO, is discussed. The model was implemented in Quintus Prolog on a Sun Workstation and exported to a Macintosh computer. This model has two levels of morphophonological representation, lexical and surface levels, associated by…

Describes HTML (HyperText Markup Language) and its use on the Internet's World Wide Web, including main HTML tags and their syntaxes. Alternatives to HTML, such as Adobe's Acrobat software and Sun's new Java application language, are briefly described. (Author/LRW)

This paper has shown how XML (extensible Markup Language) can be used to mark up content. Since XML documents, with meaningful tags, can be interpreted easily by humans as well as computers, they are ideal for the interchange of information. Because XML tags can be defined by an individual or organization, XML documents have proven useful in a…

E-learning provides a convenient and efficient way for learning. Formative assessment not only guides student in instruction and learning, diagnose skill or knowledge gaps, but also measures progress and evaluation. An efficient and convenient e-learning formative assessment system is the key character for e-learning. However, most e-learning…

Portfolio authoring tools within teacher preparation institutions have changed dramatically as portfolios have moved from paper to electronic formats and now to the Web. This study used Engestrom's Cultural-Historical Activity Theory (1987) to examine how portfolio tools, along with external influences and institutional contexts, mediate the…

This paper presents a goal-based scenario approach to teaching introductory database concepts to undergraduates using two different scaffolding methods. One method, termed "worked-out examples," attempts to reduce extraneous cognitive load by requiring students to complete increasingly complex missing parts of worked out examples. The other…

Open source has continued to evolve and in the past three years the development of a graphical user interface has made it increasingly accessible and viable for end users without special training. Open source relies to a great extent on the free software movement. In this context, the term free refers not to cost, but to the freedom users have to…

The popularity of web-based learning systems has encouraged researchers to pay attention to several new issues. One of the most important issues is the development of new techniques to provide personalized teaching materials. Although several frameworks or methods have been proposed, it remains a challenging issue to design an easy-to-realize…

This student book presents information, games, and activities designed to develop computer literacy and skills. The text is aimed at middle elementary level students but may be adapted for use with younger or older students. Topics are presented in sequence to provide a complete knowledge base. However, each topic is presented with clarity that…

Many have had high expectations for the impact of computer-based technology on educational practice. By and large, these expectations have not been realised. It has become evident that innovative technology alone does not necessarily guarantee progress--nor perhaps even significant change--in educational practice. This has led educational…
