This paper describes an investigation looking at the underlying mathematics of poker machines. The aim of the investigation is for students to get an appreciation of how poker machines are designed to ensure that in the long-term players will inevitably lose when playing. The first part of this paper describes how students can model a simple poker…

Snowflakes falling in Brisbane, Australia would likely make news headlines during any season of a given year, even during winter. Year 8 students at Ormiston College which is located in Brisbane, have made their own snowflakes--of a kind. Using the programming language Scratch, all Year 8 Mathematics students wrote code to construct Swedish…

In this paper, an example is offered of a problem-solving task for senior secondary school students which was given in the context of a story. As the story unfolds, the task requires progressively more complex forms of linear programming to be applied. Coding in MATLAB is used throughout the task in such a way that it supports the increasing…

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…

In the first issue of "Australian Educational Computing," in 1986, Cumming and Abbott reported a controlled comparison of top-down and bottom-up teaching strategies for Grade 5 and 6 students' use of a simple logic programming language. They found that both strategies were rated highly by students and teachers, and gave useful learning;…

Discusses the use of computers in undergraduate mathematics. Highlights include external software, including spreadsheets and theorem provers; computer generated assessment; multimedia software; computer programming languages; geometric visualization tools; computer algebra systems; and examples from the United States, the United Kingdom, and…

This book presents examples of how libraries are using XML (eXtensible Markup Language) to solve problems, expand services, and improve systems. Part I contains papers on using XML in library catalog records: "Updating MARC Records with XMLMARC" (Kevin S. Clarke, Stanford University) and "Searching and Retrieving XML Records via the…
