DIMPACK Version 1.0 for assessing test dimensionality based on a nonparametric conditional covariance approach is reviewed. This software was originally distributed by Assessment Systems Corporation and now can be freely accessed online. The software consists of Windows-based interfaces of three components: DIMTEST, DETECT, and CCPROX/HAC, which…

The advances in information technologies and the Internet significantly promote the prosperous growth of electronic commerce in recent years. Simply surfing the Internet allows consumers to conveniently explore endless product choices and a flood of related product information. As one of the most important sources of product information,…

Aspect-oriented software design (AOSD) enables better and more complete separation of concerns in software-intensive systems. By extracting aspect code and relegating crosscutting functionality to aspects, software engineers can improve the maintainability of their code by reducing code tangling and coupling of code concerns. Further, the number…

This article discusses the accessibility of two content management systems, Berkeley Electronic Press's Digital Commons and OCLC's CONTENTdm, widely used in libraries to host institutional repository and digital collections content. Based on observations by a visually impaired student who used the JAWS screen reader to view the design and display…

This paper investigates the uses of the aorist and the progressive tenses in spoken Turkish and the extent to which they are used interchangeably. Demo version of Spoken Turkish Corpus was analyzed using EXMARaLDA software. The tokens were divided into the categories of uses. Results indicate that there were a total of 206 tokens of the aorist and…

The University of Wolverhampton has been using Turnitin as a teaching aid with groups of students since 2007, but in 2011 changed its policy to encourage student access on a formative basis across the institution. In one School, 748 students undertaking final year undergraduate projects were invited to check multiple drafts via Turnitin before the…

Growth is a concept of particular interest for economic discourse. This paper sets out to explore a small corpus of economic growth, which consists of articles from "The Economist". The corpus software used in this study is a web-based tool Wmatrix, an automatic tagging software able to assign semantic field (domain) tags, and to permit…

Instructional developers and others creating apps must choose from a wide variety of app development tools and technologies. Some app development tools have incorporated visual programming features, which enable some drag and drop coding and contextual programming. While those features help novices begin programming with greater ease, questions…

An important factor for success in project-based learning (PBL) is that the involved project groups establish an atmosphere of social interaction in their working environment. In PBL-scenarios situated in distributed environments, most of a group's work-processes are mediated through the use of production-focused tools that are unconcerned with…

Assistive Technology (AT) revolutionized the process of learning for special needs students during the past three decades. Thanks to this technology, accessibility and educational inclusion became attainable more than any time in the history of special education. Meanwhile, assistive technology devices remain unreachable for a large number of…

This paper investigates the use of a cloud computing environment to facilitate the teaching of web development at a university in the Southwestern United States. A between-subjects study of students in a web development course was conducted to assess the merits of a cloud computing environment instead of personal computers for developing websites.…

Context is what makes mathematical modeling tasks different from more traditional textbook word problems. Math problems are sometimes stripped of context as they are worked on. For modeling problems, however, context is important for making sense of the mathematics. The task should be brought back to its real-world context as often as possible. In…

EvoluZion is a forward-in-time genetic simulator developed in Java and designed to perform real time simulations on the evolutionary history of virtual organisms. These model organisms harbour a set of 13 genes that codify an equal number of phenotypic features. These genes change randomly during replication, and mutant genes can have null,…

Computer-based spell checkers help to correct misspells instantly. Almost all the word processing devices are now equipped with a spell-check function that either automatically corrects errors or provides a list of intended words. However, it is not clear on how the reliance on this convenient technological solution affects spelling learning.…
