The ability to scan retention data over a wide range of eluent composition opens up the possibility of a computerized selection of the optimal separation conditions. The major characteristics of retention behavior, peak-shape effects and pH effects evident in ion chromatography (IC) using common stationary phases and eluents are illustrated.

Computer algebra systems are frequently used for research. In addition, some instructors have based entire advanced courses around these systems. One benefit is that they allow students to become familiar with the methods of calculus by individual experimentation. However, instructors have generally seen computer algebra systems as unsuitable for…

This study used verbal protocol analysis to examine the behavior of an individual with visual impairment using a self-voicing application to find information on the World Wide Web. The results indicated that executing actions (such as typing or pressing keys) and interpreting the computer system's state (data gathering) were the most frequent and…

This article provides suggestions for developing a laboratory-based research methods course using computers. We describe important considerations for creating this type of course including selecting software, choosing experiments, and teaching students with different levels of computer skill. We also include 3 model projects that required…

This paper describes a series of awareness-raising activities for English language secondary school teachers-in-training -- with a view to evaluating future, that is, "intelligent", CALL for English language teaching. The paper first puts the development of CALL applications into perspective (after Atwell, 1999; Warschauer and Healey,…

This article describes a simple computer program which graphically demonstrates both Type I and Type II statistical errors.

Conventional wisdom says that people should not buy anything in education until research is seen. The following questions should be asked: (1) Does that particular technology enhance learning? (2) Does that piece of software increase test scores? and (3) Do those machines reduce absenteeism? Of course the answer is always yes. No vendor is going…

Which high-tech products give you the most grief? Surprisingly, more people singled out TiVo and replay digital recording systems than personal computers, according to a recent survey by Best Buy. Nine percent of people said they found these TV devices difficult to use. The same percentage found PDAs (personal digital assistants) difficult. Only 2…

Robots make a wonderful context for teaching students about many concepts important to technological literacy. They can provide an authentic context and produce high levels of motivation. According to Standards for Technological Literacy: Content for the Study of Technology (STL) (ITEA, 2000, 2002), there are six core concepts that should be…

This paper will discuss our approach to, success with and future direction in rapid prototyping for architectural modeling. The premise that this emerging technology has broad and exciting applications in the building design and construction industry will be supported by visual and physical evidence. This evidence will be presented in the form of…

Virtual reality (VR), as an emerging visualization technology, has introduced an unprecedented communication method for collaborative design. VR refers to an immersive, interactive, multisensory, viewer-centered, 3D computer-generated environment and the combination of technologies required to build such an environment. This article introduces the…

The Archivists' Toolkit is a software application currently in development and designed to support the creation and management of archival information. This article summarizes the development of the application, including some of the problems the application is designed to resolve. Primary emphasis is placed on describing the application's…

When properly utilized, the Internet can transcend the limitations of physical space, supporting the freedom of imagination and information on which the library profession is founded. The software described in this article (WebCalender, Dynix, Mambo) can benefit libraries by allowing their patrons to take full advantage of today's technologies.

The ready availability of Internet resources has made it easier than ever for students to plagiarize and many higher education institutions have resorted to checking essays with plagiarism detection software. Student behaviour is likely to change in response to this increased scrutiny but not necessarily in the desired direction. Internet…

When a mid-sized public college made a politically unpopular decision to purchase new student information system software, a team of fourteen people from across campus was assembled and charged with facilitating the transition from the home-grown system. This case report describes the challenges they faced as they worked to understand their…
