In teaching undergraduate time series courses, we have used a mixture of various statistical packages. We have finally been able to teach all of the applied concepts within one statistical package; R. This article describes the process that we use to conduct a thorough analysis of a time series. An example with a data set is provided. We compare…

In this article, "Translation Commentary" refers to an English composition written by a learner of both English and translation, submitted together with his or her translation output. In an academic setting combining English-to-Chinese translation and English as a second language, this article deals with both the issue of translation and that of…

An RSS feed is a list of topics made available from a webpage via a standard XML file format known as RSS, an abbreviation of either Really Simple Syndication or Rich Site Summary (Wikipedia, 2006). The end-user subscribes to their favorite Internet content site via RSS-aware software. Once subscribed, announcements with appropriate links are…

The way in which computer algebra systems, such as Maple, have made the study of physical problems of some considerable complexity accessible to mathematicians and scientists with modest computational skills is illustrated by solving the multiple pendulum problem. A solution is obtained for four pendulums with no restriction on the size of the…

The existing maximum likelihood theory and its computer software in structural equation modeling are established on the basis of linear relationships among latent variables with fully observed data. However, in social and behavioral sciences, nonlinear relationships among the latent variables are important for establishing more meaningful models…

Some students show a lot of artistic talent. Astounding sketches of a Mini Cooper done with a pen in an English-composition spiral-bound notebook scream talent and success. But teachers, parents and guidance counselors want to help artistically talented kids avoid the macaroni-and-cheese existence common to aspiring artists--working just to make…

With new and inexpensive computer-based methods, measuring the speed of light and the Earth's radius--historically difficult endeavors--can be simple enough to be tackled by high school and college students working in labs that have limited budgets. In this article, the author describes two methods of estimating the Earth's radius using two…

Technological tools have the potential to offer students the possibility to represent information and relationships embedded in problems and concepts in ways that involve numerical, algebraic, geometric, and visual approaches. In this paper, the authors present and discuss an example in which an initial representation of a mathematical object…

If we look into the past we will discover that the teachers of thermodynamics were always trying to interpret an important part of their science by using geometry. The relation between geometry and thermodynamics is of great interest and importance in teaching thermodynamics. This article examines the way undergraduate students of thermodynamics…

Helping students understand the general nature of scientific models is increasingly regarded as an important goal of the middle and high school science curriculum (e.g., J. K. Gilbert & C. Boutler, 1998. "International Handbook of Science Education"; Kluwer, London; A. G. Harrison & D. F. Treagust, 2000. "Science Education," 352-381). In addition,…

In this study, the author explored the extent to which students read the supplemental, in-chapter material contained in introductory accounting textbooks. A total of 668 students enrolled in 2002 spring and fall semesters at 3 universities in the southern United States participated in the study. The results showed that the participants considered…

Intelligent learning systems (ILSs) have evolved in the last few years basically because of influences received from multi-agent architectures (MAs). Conflict resolution among agents has been a very important problem for multi-agent systems, with specific features in the case of ILSs. The literature shows that ILSs with cognitive or pedagogical…

This article discusses a computer game design and animation pilot at Washington County Technical High School as part of the advanced computer applications completer program. The focus of the instructional program is to teach students the 16 components of computer game design through a team-centered, problem-solving instructional format. Among…

Outline Processor Markup Language (OPML) is an emerging format that allows for the creation of customized research packages to push to patrons. It is a way to gather collections of Web resources (links, RSS feeds, multimedia files), organize them as outlines, and publish them in a format that others can share and even subscribe to. In this…

A small class of functions is described that easily lend themselves to two-dimensional and three-dimensional visualizations at the basic calculus level. The intended audience is those educators involved in the instruction of elementary calculus. This note is an educational piece that begins with the question: "What happens if a function defined on…
