A heuristic description is given of the rediscovery with "Sketchpad" of a less-well-known, but beautiful, generalization of the nine-point circle to a nine-point conic, as well as an associated generalization of the Euler line. The author's initial analytic geometry proofs, which made use of the symbolic algebra facility of the TI-92 calculator,…

The global software industry is in the midst of a major evolutionary shift--one based on open computing--and this trend, like many transformative trends in technology, is being led by the IT staffs and academic computing faculty of the higher education industry. The elements of this open computing approach are open source, open standards, open…

Asynchronous computer conferencing refers to the use of computer software and a network enabling participants to post messages that allow discourse to continue even though interactions may be extended over days and weeks. Asynchronous conferences are time-independent, adapting to multiple time zones and learner schedules. Such activities as…

Forty Swedish elementary students, 7-12 years of age and working in pairs, constructed a series of bar graphs and pie charts using a graphing application software as an instructional tool under the guidance of the researcher. After successive withdrawal of help, each pair drew a small number of graphic displays manually at the end of the data…

There is a tremendous amount of pressure on educators to incorporate highly advanced computer-mediated communication (CMC) into the classroom, but the research shows that this is not an easy task. Part of the difficulty learners experience within current network applications is a lack of support from the design of the software for the development…

With the advent of English as a global language, the ability to write well in English across diverse settings and for different audiences has become an imperative in second language education programmes throughout the world. Yet the teaching of second language writing is often hindered by the great amount of time and skill needed to evaluate…

The present paper describes the design, implementation and evaluation of a cryptography module for final-year software engineering students. The emphasis is on implementation architectures and practical cryptanalysis rather than a standard mathematical approach. The competitive continuous assessment process reflects this approach and rewards…

The computer numerical control (CNC) flatbed router is a powerful tool and a must-have piece of equipment for any technology education program in which students will produce a product--whether it involves Manufacturing, Materials Processing, or any of the vast array of Project Lead the Way courses. This article describes an activity--producing a…

As the frequency with which Classroom Response Systems (CRSs) are used is increasing, it becomes more and more important to define the affordances and limitations of these tools. Currently existing literature is largely either anecdotal or focuses on comparing CRS and non-CRS environments that are unequal in other aspects as well. In addition, the…

Data-logging exercises in science classrooms assume that with the proper scaffolding and provision of contexts by instructors, pupils are able to meaningfully comprehend the experimental variables under investigation. From a case study of knowing and learning in a fish hatchery using real-time computer statistical software, we show that…

This paper describes how the Multi-Attribute Utility Theory can be combined with adaptive techniques to improve individualised teaching in an Intelligent Learning Environment (ILE). The ILE is called Web F-SMILE, it operates over the Web and is meant to help novice users learn basic skills of computer use. Tutoring is dynamically adapted to the…

This paper outlines a research project in which three- and four-year-old children in one nursery engaged with editing software to create short animated films. Research questions were related to the knowledge and understanding of multimodal texts that the children developed in the activity, the skills they demonstrated in undertaking the animation…

Every dollar counts in today's school libraries, where a resource is evaluated not just by the cost, but also by how many students will utilize it. A recent survey shows that many school librarians rely on their state to help provide (and pay for) databases that their students can access from the school media center or at their public library.…

This paper provides a brief description of Hyper-G, the first second-generation hypermedia system. The first section identifies problems with first generation hypermedia systems. The following sections discuss the new concepts that are implemented in Hyper-G, including user accounts and billing, structuring of data, caching and replication, native…

At the request of state legislature, the two-year branch campus of New Mexico State University at Alamogordo (NMSU-A) began using an economic impact model developed by the Eastern Association of College and University Business Officers (EACUBO) to document accountability. The EACUBO Model uses information about the institution and economic data…
