Computer programs and models are used to express respect for life by not sacrificing any animal but these alternatives might be deeply flawed. Alternatives to dissection are perverse alternatives that tend to preserve the features of inappropriate dissections like destructiveness, reductionism and objectification.

Chris Davis and Jennifer Davis embrace the teaching environment of their science and technology magnet school. Using their students? skills in Web development, PowerPoint, Photoshop, and other technologies, the authors create lessons that help students ?make connections with one another and with the community.?

Research on psychometric methods is heavily dependent on software. The quality, availability, and documentation of such software are critical to the advancement of the field. In 2000, an ad hoc committee of NCME recommended that NCME adopt policies that promote greater availability and better documentation of software. This article follows the ad…

In this article, the main characteristics of the educational browser YADBrowser are described. One of the main objectives of this project is to define new languages and object models which facilitate the creation of educational applications for the Internet. The fundamental characteristics of the object model of the browser are also described.…

Metadata is often created in a time-consuming process by catalogers, digital library technicians, and others. It is then underused in the systems. But recent experiments by some library organizations indicate that only the surface is being scratched on what data can do. The American West Project at the California Digital Library (CDL) is…

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…
