Negation, conjunction, and disjunction are major building blocks in the formation of concepts. This article presents a new model-based theory of these Boolean components. It predicts that individuals simplify the models of instances of concepts. Evidence corroborates the theory and challenges alternative accounts, such as those based on minimal…

Adoption of technology for teaching and learning is not as significant as the adoption and use of software that is used as a pedagogical extension of a teacher's approach to classroom instruction. It is the dynamic and integrated use of software that extends the pedagogical role of the teacher beyond the traditional lecture and discussion format.…

Information spreads online at a much faster rate than ever before, often without being confirmed by trustworthy sources. Students must be able to evaluate the online source and the online source's information for accuracy and credibility. In public speaking, argumentation, and persuasion classes (among others), students are taught to use confirmed…

Some have called plagiarism literary theft. Plagiarizing is akin to stealing the intellect of another person. At times, plagiarism occurs because of ignorance, sloppy authorship, or lack of knowledge about proper sourcing. Sometimes, it is done purposefully. Experts have suggested that the concept of intellectual ownership is limited to Western…

A small-group, web-interactive approach to teaching precalculus concepts was investigated. Following an online pretest, 3 participants were given a brief (15 min) presentation on the details of reciprocal math relations and how they operate on the coordinate axes. During baseline, participants were tested regarding their ability to construct…

In December, Microsoft announced a major security flaw affecting its Internet Explorer web browser. The flaw allowed hackers to use hidden computer code they had already injected into legitimate websites to steal the passwords of visitors to those sites. Reportedly, more than 10,000 websites were infected with the destructive code by the time…

Elearning has grown rapidly in importance for institutions and has been largely facilitated through the "walled garden" of the virtual learning environment. Meanwhile many students are creating their own personal learning environments by combining the various Web 2.0 services they find most useful. Cloud computing offers new…

A significant body of research identifies a large number of team composition characteristics that affect the success of individuals and teams in cooperative learning and project-based team environments. Controlling these factors when assigning students to teams should result in improved learning experiences. However, it is very difficult for…

Server virtualization enables a physical computer to support multiple applications logically by decoupling the application from the hardware layer, thereby reducing operational costs and competitive in delivering IT services to their enterprise organizations. IT organizations continually examine the efficiency of their internal IT systems and…

The Internet Age has seen the emergence of richly annotated image data collections numbering in the billions of items. This work makes contributions in three primary areas which aid the management of this data: image representation, efficient retrieval, and annotation based on content and metadata. The contributions are as follows. First,…

This article shares some personal reflections on several years of integrating educational technology into mathematics courses while retaining the direct interaction strengths of the traditional classroom.

Open source software is poised to make a profound impact on K-12 education. For years industry experts have been predicting the widespread adoption of open source tools by K-12 school districts. They're about to be proved right. The impact may not yet have been profound, but it's fair to say that some open source systems and non-proprietary…

In this paper, I suggest that it is perhaps time to consider the pedagogy of popular music in more extensive terms than conventional rock band practices have to offer. One direction in which this might lead is the expansion of the informal pedagogy based on a "garage band" model to encompass various modes of digital artistry wherever this artistry…

This article examines how Moodle, as an open-source Learning Management System, can be made more interoperable. The authors tested two software standards, LAMS and RELOAD, compatible with socio-constructivism norms. The analysis showed that pedagogic activities created with the LAMS-IMS Learning Design Level A Format are useable with Moodle but…

Geographically related queries form nearly one-fifth of all queries submitted to the Excite search engine and the most frequently occurring terms are names of places. This paper focuses on digital libraries and extends the basic services of existing library management systems to include new ones that are dedicated to geographic information…
