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…

ISO--International Organization for Standards highlights the activities of WG8 (Working Group 8 of ISO) in the alignment of standards for a common tree model and common query languages. Examines the how Document Style Semantics and Specification Language (DSSSL) and HyTime make documents easier to work with and more powerful in their ability to…

Reports on a computer application in which collaboration did not precede project design. Important project parameters established without author input presented ethical dilemmas in balancing contract obligations and methodological rigor. (Author/CK)

Proposes a model for digital library and hypermedia organizations that is adaptive, providing different conceptual orderings to support browsing for different individuals' or groups' needs. Highlights include types of links, document ordering and the Gray code (a binary programming code), adaptive classification, and an economic model for document…

Describes CGI (Common Gateway Interface) scripts that are available on the Web and explains how librarians can use them to make Web pages more interactive. Topics include CGI security; Perl scripts; UNIX; and HTML. (LRW)

Discusses downloadable executable content, or mobile code, on the World Wide Web; evaluates the security features offered by the Java and Safe-Tcl programming languages; and describes the basic mechanisms of each of the proposed security models. Presents current implementations, as well as upcoming extensions, and evaluates their efficiency and…

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…

While the object oriented paradigm and its instantiation within programming languages such as Java has become a ubiquitous part of both the commercial and educational landscapes, its usage as a visualization technique within mathematics undergraduate programmes of study has perhaps been somewhat underestimated. By regarding the object oriented…

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…

Advances in information and communication technologies give us the ability to reach out beyond the time and place limitations of the traditional classroom. However, effective online teaching is more than just transferring traditional courses to the World Wide Web (WWW). We describe how we have used "off the shelf" software and the infrastructure…

This paper describes applications of logic programming technology to the teaching of the inductive method in computer science and mathematics. It discusses the nature of inductive thought and its place in those fields of inquiry, arguing that a complete logic programming system for supporting inductive inference is not only feasible but necessary.…

The idea of using "Learning Objects" in teaching has become very popular in the last few years. Although the concept of using objects in teaching is not new, the power of the computer technology and the Internet gives educators large opportunities and endless combination of possibilities in applying new theories to web-based education.…

The use of programming language was studied in an eighth grade science classroom. The goal of the EMERGE curriculum is to enable students to understand the global patterns that they observe. EMERGE was used in an eighth-grade classroom of 12 students, with a range of abilities (3 had learning disabilities), in 21 sessions over 3 months. For the…

Introductory courses in computer science at colleges and universities have undergone significant changes in 20 years. This article provides an overview of the history of introductory computer science (FORTRAN, ANSI flowchart symbols, BASIC, data processing concepts, and PASCAL) and its future (robotics and C++).
