Increasingly, colleges and universities are turning to open source as a way to meet their technology infrastructure and application needs. Open source has changed life for visionary CIOs and their campus communities nationwide. The author discusses what these technologists see as the benefits--and the considerations.

The present study investigated the utility of employing computerized speech content analysis software to detect feigned depression in psychologically healthy adults. Twenty-two subjects between the ages of 19 and 54 years old, who scored lower than 10 on the Beck depression inventory (BDI, 1996), were asked to speak freely in response to a neutral…

This paper reports on a field-based study of online help systems at the University of Maryland. After collecting data by means of interview, observation and focus group, analysis is grounded on the contextual data, thus shedding light on particular organizational and human behavioral issues on online help systems. The objectives of this research…

Technology Roadmapping is a consensus-driven process to identify, evaluate, and select technology alternatives to satisfy the needs of a particular group of people. It serves as a high-level planning tool to support the development, implementation, and communication of technology development strategies and plans. The outcome of a technology…

This article describes an activity for secondary school students that may constitute an appropriate opportunity to discuss with them the idea of proof, particularly in an algebraic context. During the activity the students may experience and understand some of the roles played by proof in mathematics in addition to verification of truth:…

A method of rendering the design of a course visible for the purpose of discussion amongst the members of course development teams is described. The paper begins by examining the way in which design is manifested in the area of course materials development and the approaches that have been used in attempting to document designs. The strengths and…

This article describes ways in which technology-supported mathematical investigation can engage students with substantive mathematics. It focuses particularly on the ways in which the NCTM Process and Content Standards for the elementary grades can be supported by the use of interactive software such as The Geometer's Sketchpad. (Contains 6…

The article discusses the use of L-systems, which provide students with a unique method to construct line fractals, including the Koch snowflake, the Sierpinski triangle, and the Harter-Heighway dragon. Applets that use L-system theory offer a graphics tool that promotes geometric reasoning, sparks enthusiasm, and connects to historical themes in…

This article is an interview with Tu Hui regarding the relative merits of "returnees" and "indigens". Tu Hui is currently chief products inspector at the Anyi Software company and one of the many indigens engaged in Information Technology. In this article, he states that, "the weakness of the indigens sometimes lies in…

We propose to use didactical theory for the design of educational software. Here we present a set of didactical conditions, and explain how they shape the software design of Cabri-Euclide, a microworld used to learn "mathematical proof" in a geometry setting. The aim is to design software that does not include a predefined knowledge of problem…

"Computer Simulations of Salt Solubility" by Victor M. S. Gil provides an animated, visual interpretation of the different solubilities of related salts based on simple entropy changes associated with dissolution such as configurational disorder and thermal disorder. This animation can help improve students' conceptual understanding of…

The torsional potential energy surface of a chemical compounds, the accessible conformations at a specified temperature and the transition states that connect these confirmations establishes many chemical properties such as dynamic behavior, reactivity and biological activity. A conformational search of n-pentane is presented using computational…

A simple Vernier software and Technology LabPro unit was used to interface a computer with a Durrum model 110 stopped-flow apparatus using the iron (III)--thiocyanate reaction. The software can readily be used to retrieve that data from the stopped-flow apparatus using one probe to measure the voltage and a second probe to trigger the data…

An IT decision maker gives an overview of public access PC software that's useful in controlling session length and scheduling, Internet access, print output, security, and the latest headaches: spyware and adware. In this article, the author describes a representative sample of software tools in several important categories such as setup…

The "Educational Media and Technology Yearbook" is dedicated to theoretical, empirical, and practical approaches to educational media development. All chapters are invited and selected based on a variety of strategies to determine current trends and issues in the field. The 2011 edition highlights innovative Trends and Issues in Learning…
