This article describes a SAS macro to assess model fit of structural equation models by employing a test of the model-implied vanishing tetrads. Use of this test has been limited in the past, in part due to the lack of software that fully automates the test in a user-friendly way. The current SAS macro provides a straightforward method for…

The purpose of this paper is to describe a software package that can be used for performing such routine tasks as controlling listening experiments (e.g., simple labeling, discrimination, sentence intelligibility, and magnitude estimation), recording responses and response latencies, analyzing and plotting the results of those experiments,…

The NCTM curriculum states that students should be able to "compare and contrast the real number system and its various subsystems with regard to their structural characteristics." In evaluating overall conformity to the 1989 standard, the National Council of Teachers of Mathematics (NCTM) requires that "teachers must value and encourage the use…

The Wireless Online Tutoring System (WOTS) is a web-based, synchronous groupware system that has been developed to facilitate student collaboration in group projects. It supports interactive and collaborative structured-diagramming and is equipped with group awareness features such as remote cursors, locking, and textbased instant messaging. Users…

In this article, the author describes his experience when Kathy Nichols contacted him seeking suggestions, recommendations--really anything he could think of--that might help her seize control of a bewildering and rapidly surging torrent of digital image files. The challenges that Nichols described interested him, and he felt they might be…

Today, a plethora of Web sites and software packages are designed specifically for English language learners, and not only are most teacher candidates well-versed in how to use technology, they are likely familiar with numerous software programs that are appropriate to use with children. Although teacher candidates may be well-trained in how to…

Providing quality technical support in K-12 environments can be challenging. Unlike the business world, there is generally a less-than-ideal ratio of technical staff to computers, numerous software titles from dozens of vendors, and of course--a much smaller budget. The Victor Central School District in Victor, New York, has employed a number of…

BusinessThinking [TM] is a computer-based e-learning package designed to teach technology skills and business information to adults, ages 50-69, who remain in the workforce. This article outlines results from usability testing for the material on using technology applications (Microsoft Word, PowerPoint, Excel and the Internet), and career…

One of the most beneficial uses for technology in the science classroom is data manipulation. During labs and other learning experiences, students can quickly put the data they collect into spreadsheets or databases. Then they can make comparisons, create graphs, draw conclusions, sort the data in new ways, and, ultimately, give their data…

Over the last 5 years we have developed, produced, tested, and evaluated an authoring software package to produce web-based, interactive, audio-enhanced language-learning material. That authoring package has been used to produce language-learning material in French, Spanish, German, Arabic, and Tamil. We are currently working on increasing…

With increases in the use of structural equation modeling (SEM) in the social sciences, graduate course offerings in this statistical technique can be expected to increase. Knowledge of the content of current SEM course offerings may provide ideas to instructors developing new courses or enhancing current courses. This article discusses results…

India has seen its economic fortunes take off in recent years. Last year, its gross domestic product rose 8 percent over 2004 in response to an expanded manufacturing sector. The country's large English-speaking population is leading India's transition into a world leader in the software services industry. American universities have taken notice,…

The expression of genes in cells of various tissue types varies considerably and is correlated with the function of a particular organ. The pattern of gene expression changes in diseased tissues, in response to therapy or infection and exposure to environmental mutagens, chemicals, ultraviolet light, and ionizing radiation. To better understand…

Item response theory (IRT) has become one of the most popular scoring frameworks for measurement data. IRT models are used frequently in computerized adaptive testing, cognitively diagnostic assessment, and test equating. This article reviews two of the most popular software packages for IRT model estimation, BILOG-MG (Zimowski, Muraki, Mislevy, &…
