Describes a tutorial tool which allows the execution of a C program to be graphically displayed. VINCE (Visual Instruction for Novices in a C Environment) is written in Java, allowing it to be used on the Web. Students can enter their own C code, or select from a menu of pre-written tutorials, each illustrating a particular aspect of programming.…

A study was conducted to propose a research-based model for a longitudinal data research system that addressed recommendations from a synthesis of literature related to: (1) needs reported by the U.S. Department of Education, (2) the twelve mandatory elements that define federally approved state longitudinal data systems (SLDS), (3) the…

Jmol is free, open source software for interactive molecular visualization. Since it is written in the Java[TM] programming language, it is compatible with all major operating systems and, in the applet form, with most modern web browsers. This article summarizes Jmol development and features that make it a valid and promising replacement for…

The primary purpose of the study was to determine if a treatment that concentrates on building programs from previously written modules can improve the decomposition processes of novice programmers in the C++ programming language and, hence, programming performance. For purposes of performance analysis, a subsample of 23 students was divided into…

This paper introduces Ontoolsearch, a new search system that can be employed by educators in order to find suitable tools for supporting collaborative learning settings. Current tool search facilities commonly allow simple keyword searches, limiting the accuracy of obtained results. In contrast, Ontoolsearch supports semantic querying of tool…

eXtensible Markup Language (XML) is a new technology that is currently being extolled by many industry experts and software vendors. Potentially it represents a platform independent language for sharing information over networks in a way that is much more seamless than with previous technologies. It is extensible in that XML serves as a "meta"…

This paper provides operational semantics for imperative programming languages that legitimize the phraseology used in the statement and proof of a fundamental theorem of program correctness. Some of the phrases used in the theorem are normally undefined, but intuitively appealing. This paper attempts to give precise meaning to the questionable…

This article describes the Australian Informatics Competition (AIC), a non-programming competition aimed at identifying students with potential in programming and algorithmic design. It is the first step in identifying students to represent Australia at the International Olympiad in Informatics. The main aim of the AIC is to increase awareness of…

Personalization of user interfaces for browsing content is a key concept to ensure content accessibility. In this direction, we introduce concepts that result in the generation of personalized multimodal user interfaces for browsing XML content. User requirements concerning the browsing of a specific content type can be specified by means of…

We present COLLECT-UML, a constraint-based intelligent tutoring system (ITS) that teaches object-oriented analysis and design using Unified Modelling Language (UML). UML is easily the most popular object-oriented modelling technology in current practice. While teaching how to design UML class diagrams, COLLECT-UML also provides feedback on…

Individualized exercises are a promising feature in promoting modern e-learning. The focus of this article is on the QuizPACK system, which is able to generate parameterized exercises for the C language and automatically evaluate the correctness of student answers. We introduce QuizPACK and present the results of its comprehensive classroom…

This chapter states and explains that a Learning Design is the result of a knowledge engineering process where knowledge and competencies, learning design and delivery models are constructed in an integrated framework. We present a general graphical language and a knowledge editor that has been adapted to support the construction of learning…

Introduction: In this research project, an empirical pilot study on the relationship between JavaScript™ usage and Website visibility was carried out. The main purpose was to establish whether JavaScript™- based hyperlinks attract or repel crawlers, resulting in an increase or decrease in Website visibility. Method: A literature survey has…

Three different approaches to teaching introductory programming are reviewed: the incremental approach, the sub-language approach, and the mini-language approach. The paper analyzes all three approaches, providing a brief history of each and describing an example of a programming environment supporting this approach. In the incremental approach,…

Discusses computational tools for learning programming and describes a system that was developed to help university students acquire the capability to model computational problems independently of a specific programming language. User-system interaction is explained; and system architecture is described, including specification acquisition, a…
