Recognition of the need to move from research "on" children to research "with" children has prompted significant theoretical and methodological debate as to how young children can be positioned as active participants in the research process. Visual research methods such as drawing, photography, and videography have received…

Learning mathematics is a complex and dynamic process. In this paper, the authors adopt a semiotic framework (Yeh & Nason, 2004) and highlight programming as one of the main aspects of the semiosis or meaning-making for the learning of mathematics. During a 10- week teaching experiment, mathematical meaning-making was enriched when primary…

There is a critical need for research into the use of digital technologies to support the assessment of performance on complex tasks in schools. This paper reports on a component of a pilot study aimed at investigating the use of digital forms of performance assessment, manageable within schools, with high levels of reliability and capable of…

Modern information technology and computer science curricula employ a variety of graphical tools and development environments to facilitate student learning of introductory programming concepts and techniques. While the provision of interactive features and the use of visualization can enhance students' understanding and assist them in grasping…

With computers, tangible tools are represented by the hardware (e.g., the central processing unit, scanners, and video display unit), while intangible tools are represented by the software. There is a special category of computer-based software tools (CBSTs) that have the potential to mediate cognitive processes--computer-based cognitive tools…

This survey examined the home pages of 36 Australian university library World Wide Web sites. Reports were run on these pages, using a service that checks the HTML for validity and reports errors, a service that checks usability by the visually disabled, and a program that checks the HTML, corrects and reports errors, and improves efficiency style…

Examined how exposure to a program of fractal computer graphics affected the perceptual sensitivity of sixth-grade students (n=197) to the natural visual environment. MANCOVA analysis of collected data and students' written responses to questions indicated that environmental perceptual sensitivity was higher for subjects exposed to fractal images.…
